1.1 GENERAL DESCRIPTION. The MUNRO Multi-Sett, hydraulic post driver is the
latest development in linkage-mounted post setting ma-
chines originally pioneered by us in 1963. It can be
easily fitted to any category 1 or 2 linkage tractor, pow-
ered from the tractor hydraulic supply, or from a P.T.O.
driven power pack.
In-built hydraulic tilt to the mast in two directions ena-
bles the Multi-Sett to operate effectively on sloping
ground, in fact, in any country accessible to the tractor to
which it is mounted. It uses an earth auger, semi auto-
matically swung into position, to drill a pilot hole into
which a post is driven. Auger sizes and cutting tips are
supplied to cope with most soil structures.
Emphasis in design and manufacture has been given to
durability, safety and performance, hence it is eminently
suited to farm fencing, fencing contractors, construction
authorities, etc. Controls are conveniently positioned for
safe precise and ergonomic operation.
1.2 HOW IT OPERATES. By moving the tractor, the Multi-Sett is positioned over
the spot where the post is to be driven. The forward/ aft
and side tilt controls are used to level the machine. The
built-in spirit level helps to ensure that the hole will be
vertical. The auto-digger is then swung into position
under the raised dolly (or hammer) so that the hole is
bored with the machine aligned in the driving position.
An auger of a diameter to suit the particular soil and size
of post is then selected and a pilot hole is bored to the
desired depth - up to 1.2M (48") if required. The weight
of the heavy dolly provides the force to feed the auger
into the soil, while the rate of penetration is easily and
infinitely controllable with a hand control. The auger is
then extracted by raising the dolly and the digger is
automatically swung clear of the dolly to its stowed
position.
above the prepared hole, the Multi-Sett is now ready for
driving. The post, which should be roughly pointed, is
placed over the hole and may be smacked into the
ground after the guard is swung into position.
Hydraulic power is used to raise the dolly to the top of
the mast. Free fall of the dolly then drives the post into
the ground. The pinch bar and chain are used to hold and
correct the alignment of the post whilst it is driven.
Continual up and down motion is readily controlled by
the dolly control handle until the post is driven to the
required depth. The dolly is under strict control at all
times, enabling short strokes if required. Also, if
desired, the dolly can be stopped in mid-flight.
At the top of its stroke, the dolly is brought to rest softly
by an in-built hydraulic damper. At the bottom of its
stroke, the dolly can rest on a rubber buffer in contact
with a rest plate. Care should be taken to arrest a freely
falling dolly by centralising the dolly control valve
BEFORE the buffer strikes the rest plate.
Dolly must be slowly lowered to the bottom of its
stroke using the bleed valve when not driving a post.
SECTION 1.
The control panel is conveniently located on the right
hand side with the hydraulic controls grouped for easy,
natural operation. Directional control information is
displayed on the panel. Safety guards allow the operator
to stand at the control panel close to the machine while
preventing them coming into contact with dangerous
parts of the machine during operation. Safety is further
enhanced by spring centring hydraulic controls. If a
control lever is released the action it controls stops
immediately
is obtainable eliminating difficulty in moving the
machine to the vertical position. Side tilt of 12 degrees
off vertical in either direction. Fore and aft tilt relative to
tractor depends on individual tractors. An average
would be 12 degrees in either direction. Angle of tilt may
be restricted by either tractor cabs, roll bars or
mudguards.
Stabiliser pads are provided to set the machine firmly on
the ground and eliminate the slack of sloppy tractor
linkages. Tilt action does not affect stability.
1.3.3 DIGGER AND AUGER DRIVE CARRIAGE.
This is easily swung from engaged to stowed position
with an automatic system utilising gravity, a ramp and
roller system. When engaging, it is simply a matter of
raising the dolly carriage to the extent of its travel,
bumping the unlatch lever and the digger automatically
swings into the drilling position where it is locked into
place by a small vertical movement of the dolly.
Disengaging is simply a matter of raising the dolly and
digger to the extent of its travel and the digger then
automatically disengages and stows to the side.
The auger drive shaft is spring mounted to provide
flexibility for the shaft in the case of an auger deflecting
off a rock during drilling.

Auger speed varies with engine speed or oil flow setting.
Ideal speed relates to ground condition and diameter of
auger. Desirable speed is 60-180 RPM with the faster

bleed valve to cope with the variety of ground conditions
and possible underground obstructions. It is possible to
feel, through the system, what is happening at the cutting
face, then the feed rate for the specific conditions can be
set.
1.3.3.3 AUGER CHANGING
The auger is secured in the drive chuck with a pin. A
sliding cover locks the pin in place during operation.
This allows for very fast auger changes to be made and
also presents a snag free surface while drilling. Always
ensure that the sliding cover is correctly positioned.

conditions. Special cutters can also be provided for
more rocky and difficult ground conditions.
1.3.4 DRIVING CONTROL.
The Dolly operating lever works in the direction of dolly
travel. The operator has complete control over the dolly
at all times. Release the lever and the dolly stops
irrespective of how fast it is moving. Full stroke or short
stroke operation is easily achieved.

operational as an uncontrolled hydraulic pressure spike
can damage components.

with tractor kit. The tractor kit contains all the
attachments which are necessary to fit a Multi-Sett to a
particular tractor. It is therefore essential to state the
correct tractor details when buying a Multi-Sett.

An hydraulic pressure relief valve is factory set for open
centre hydraulic systems at 13.8 m.p.a. (2000 p.s.i.).
This protects the machine in the event of a jammed
auger, stopping the dolly suddenly or any other
mechanical blockage which may restrict a machine
function.
For closed centre tractor hydraulics the relief valve is not
used as the closed centre system relies on the pressure
setting of the tractor.
A squelch valve is included to stop the falling dolly

operator could lead to an unsafe situation. No one
should be permitted to use the machine if they have not
been trained or read this manual, especially section 4.
1.53 MANOEUVRING.
(a). In order to retain tractor stability when moving the
tractor, lower the dolly to its lowest position. Never
move the tractor with the dolly elevated. See 1.6.3.1
Tractor size section for detailed stability information
(b). Particularly in hilly country, ensure that the tractor
has ample front weight to ensure safe steering and that
the rear wheels are set at their widest position. In
climbing steep ground, it is safer to back up a slope than
to drive forward.
THE Multi-Sett
1.6.1 GUARANTEE.
The Multi-Sett is guaranteed for a period of 6 months
from the date of purchase against faulty workmanship
and/or materials. The control valves and the hydraulic
motor which drives the auger, are proprietary items and
carry the manufacturers' warranty. Faulty goods are to
be returned to Munro Engineers at the claimant’s
expense for inspection before a warranty claim can be
accepted.
The machine will normally arrive strapped dolly down
on a pallet. The operator guard is fitted up to the
machine, but restrained by cable ties. Unstrap any loose
items. Use a sling of at least 750kg capacity to lift the
machine by the top frame bow up to vertical. The sling
point is the top bow of the MultiSett frame.
The machine can be fitted direct to the tractor (See
1.6.3.2 Fitting up) or can be safely stored by placing it
on a sturdy post with the frame snug against the post and
the dolly sitting on top of the post. The pinch bar chain is
then placed around the post and fitted to the chain anchor
bracket. Lock the chain in position so that a conscious
decision must be made to remove it. An alternative
storage arrangement is to hang the machine by the top
bow on a convenient strong beam with the machine feet
just touching the ground.

1.6.3.1 TRACTOR SIZE
The machine will normally fit on all tractors with CAT 2
linkage and most tractors with CAT 1 linkage. Tractors
with CAT 3 linkage must have CAT 2 adaptors fitted to
allow the MultiSett to be fitted.
Stability during transport and use needs to be considered
when deciding on a suitable tractor. When transporting
while attached to the tractor the linkage arms and tractor
take all the loads produced by the machine. When set
down on the ground for post setting the Multisett’s
support feet provide side to side stability and the tractor
provides for / aft stability.
The tractor manufacturer must be consulted if there is
any doubt as to the stability of the tractor with the
MultiSett fitted. The following information will assist
stability assessment when travelling:
Position of centre of gravity behind linkage pins
(MultiSett in vertical attitude, Dolly lowered) - 270mm
Height of centre of Gravity above the lower linkage pins
with dolly down - 903mm
with Dolly up - 1689mm.
The stability of the tractor may be severely compromised
if the machine is moved with the dolly up. All transport
movements should be with the Dolly in its lowered
position.
1.6.3.2 FITTING UP
All that is required to mechanically fit the machine to the
tractor is to have on hand the correct linkage pins and
clips (Cat 1 or Cat 2).
Some tractors require a different length top link
extension. Top link extension length is normally decided
when the machine is purchased. The correct Top link
extension is then supplied with the machine. If the Top
link extension needs to be changed, this task must be
carried out by an authorised service person as there is a
particular procedure to be used to ensure a safe
connection between top link rod and extension.
Back your tractor up to the machine, lower the machine
until the feet are just above the ground and fit the two
lower link pins. Lower the machine until it is sitting on
the ground, but the weight is still taken by your lifting
device. Refer to the hydraulic fitting instructions
(1.6.3.4) to fit up the hydraulic supply. When the
hydraulics are connected and operating, extend the top
link cylinder and fit the top link ram to the tractor.
Check all hydraulic functions are operational and the air
bleeding procedure below has been carried out. It is now
safe to remove the lifting device from the top bow. Refer
to the next section for setting up Operator guard.
1.6.3.3 OPERATOR GUARD
The operator guard when initially fitted in the factory is
set up so that all interlocking functions work correctly.
It is essential that this guard be in place and operational
before the machine is used. Failure to keep this guard in
operating order violates the relevant Occupational Health
and Safety Regulations and could lead to serious injury.
1. WHEN MACHINE IS FITTED UP TO TRACTOR– Cut
the plastic cable ties that secure the guard in the
closed and Up position. (See Fig 1633.1)
2. CHECK - That guard slides smoothly up and
down on it’s pivot and that it falls gently under
its own weight to the lowered position.
3. CHECK - That the guard can be easily lifted and
rotated out of the operators way after the dolly
lever interlock has been engaged over the Dolly
Lever.
Check the condition of the oil in the tractor hydraulic
system. If it is time for a scheduled change, or if there is
any appearance of contamination, particularly if your
tractor is an older model, then this is the opportunity for
an oil change. Don't forget the oil filter. The Multi-Sett
hydraulic system is susceptible to dirty or contaminated
oil. Operation with dirty or contaminated oil will void
the warranty and lead to damage and a reduction in
machine performance.
Check the oil level in the tractor system both before and
after installing the Multi-Sett. The Multi-Sett has been
tested at the factory and the Grade 68 hydraulic oil used
has been drained out, but not flushed. It may take an
extra two litres of oil.
Connect the high pressure hose between the inlet of the
main control valve and the tractor supply. Similarly,
connect the low pressure hose between the return
manifold of the Post-Sett and the tractor oil sump, using
(where necessary) a suitable adaptor (not supplied in
tractor kit). The orifice size in the return hose fitting
must be greater than 16mm. The low pressure return
must not be connected to the remote hydraulic return
line. Fittings required for a specific tractor, other than in
1.4 above, are to be supplied by the customer.

1.6.4 CLEANING.
Clean, if necessary, the mast channels to ensure they are
free of grit. Lubricate slide blocks now and after every
four hours of use. Neglect of this may cause damage
which is not covered by your guarantee.
1.6.5 CHECKING OPERATING FUNCTIONS.
The operational panel on the side of the main control
valve, below, has five guide directions for the control
handle of each operating function.
1.6.5.1 Check the Tilt Functions - Each function should
work smoothly. Each operating handle moves in the
direction of tilt to give you a convenient feedback "feel"
and to assist rapid and precise vertical setting of the
Multi-Sett. Factory-set orifices in each circuit control
their rate of movement. The correct ergonomic handle
arrangement is shown above.

circulating freely through the Multi-Sett circuit. Now
remove air from the Multi-Sett functions, (dolly, digger,
fore and aft tilt and side tilt) by operating the appropriate
control handle, (see control panel directions) and moving
each action over its full stroke several times. Tilt
functions should operate smoothly without shudder.
After any remaining mechanical fit up is completed test
all functions and ensure that there is no contact with the
tractor. Tilt the machine in all directions and raise the
linkage arms to make sure all clearances are satisfactory.
Inspect all hoses to make sure they are not catching or
kinking.
1.6.3.5 Power Pack
If your machine is supplied with a power pack the tank
will be mounted on the Post Sett carry beam or on the
side shift frame if a side shift is supplied. The pump,
gearbox, fittings and hoses are packed separately. The
pump gearbox must be filled with 90 grade gear oil via
the breather filler to the level indicator located on the
side of the gear case in line with the pump shaft. Fit the
gearbox and pump on the tractor PTO using the supplied
chains to secure it and take the operating torque reaction.
Check for snag points between the gearbox and linkage
arms. The gearbox may be tilted to clear obstructions.
Connect the 25mm tank return line between the fitting on
the filter on top of the tank and the return line on the
valve bank using supplied hose clamps. Connect the high
pressure supply hose between the pump outlet and the
supply connection on the valve bank. Connect the 25mm
pump suction line between the inlet side of the pump and
the lower fitting on the tank.
Make sure all hoses describe a smooth U shape to allow
for relative movement. Any kinks will cause damage to
the hydraulics due to oil starving. When all connections
have been made, checked and tightened, fill the tank
with approx 20litres of grade 68 Hydraulic oil. Check
for oil leaks at connections and observe oil suction hose
for tell tale air leak bubbles. Refer to 1.6.3 for the
remaining hydraulic connections.
1.6.5.2 Check the Dolly movement - It is important at all
times to avoid any damage or scratching of the smooth
surface of the dolly ram-rod, as the high-pressure seal in
the top of the ram will not function on a damaged rod.
At the top of the stroke the reversal of the dolly is
cushioned by an hydraulic damper. This will function
properly as installed unless badly scored by chips or dirt
trapped in the oil. At first the damping action may seem
firm, but as the oil warms and becomes thinner, the
damping action softens.
safely at any time by simply releasing the dolly handle.
The energy of fall will be dissipated quickly through the
factory-set squelch valve.
At the bottom of the stroke, the dolly comes to rest on a
rubber buffer and rest plate. While this stop is robust,
the dolly should not be allowed to drop heavily onto this
rest - stop the dolly first on the hydraulic valve.
The dolly ram rod seal at the top of the dolly lift ram will
weep a small amount of oil in use. This is normal. If the
seal leaks to the extent that oil is dripping from the seal
area then the seal requires replacement.
1.6.5.3 Check that the fixed rear dolly rod guard is in
place. Check that the vertically sliding dolly operator
guard is in place and operated correctly. The guard
should be easy to raise and lower smoothly. The
interlocking handle should prevent downwards operation
of the dolly control lever when the guard is fully raised
and swung to the side. When swung into place and
released the guard should travel downwards smoothly
until it reaches its lowest limit.
1.6.5.4 Check Digger Engagement.
(a). Raise the dolly fully up, noting that the last 25mm
(1” ) is damped and takes a few moments.
(b). Release digger from its stow latch by pushing the
release handle above and behind the valve bank. The
Digger should rotate around to a position vertically under
the dolly. The digger trip arm roller should smoothly run
down on the lower of the two ramp sections.
(c). Use the Auger Feed valve (Bleed Valve) to lower the
dolly approximately 150mm. The left and right dolly
latches should snap shut and engage the dolly positively.
(d). Slowly lower, then raise the dolly/digger unit over its
full stroke. Use the bleed valve to lower the dolly (Not
the dolly up down lever). The digger guide rod should
pass in and out of the top pivot guide and pass smoothly
through the Digger Pivot tube below. Lightly grease the
inside of the pivot tube and Top Guide.
(e). Raise the dolly/digger fully up. Check that the
digger automatically and cleanly unlatches from the
Dolly and the trip arm roller drops onto the top ramp of
the engager ramp on the upper left side of the mast
assembly. The Digger supported by the trip arm roller

(a). Practice fitting and removing augers. Best done with
digger disengaged. Check that the auger retaining pin
cover slides easily over the pin, locking it in place. Do
not use any other pin as the safety of the locking system
will be compromised. Finally, re-stow the digger.
(b). Get the feel of the motor-control handle. Note that it
spring returns to off from either operating position. Spin
the motor without an auger both forward and reverse.
Note that the shaft stops if the dolly is raised. This is
because oil priority is given to the dolly lift cylinder.
(c). Check the motor speed against tractor revs using
table C section 3.2 to check that the tractor is performing
correctly.
(d). Get the feel of the auger feed control. This can be
done with the digger stowed. Close the handwheel just
enough to arrest dolly motion. Never over tighten.
(e). Fit auger. Raise dolly. Engage digger.
Adjust swing frame in or out from mast to suit auger and
post diameters. Using feed handwheel, lower digger
until cutter point rests on ground, then close the feed
handwheel.
Check that the auger is plumb. Set it plumb. See para
2.74.

Stop the auger and lower it onto ground surface. Rotate
and use feed valve to drill hole.
If the ground surface is rough with grass tufts, tree roots
or rocks, chip smooth with a spade to provide an even
entry for the auger.
auger jammed. Remove by sequentially raising and
reversing. Care is needed here. Reversing the auger
without raising the dolly could cause the auger cutter to
break.
should then smoothly run around the ramp, swing the
digger carriage to its stowage position. Check that the
trip arm roller is nestled in the pocket created by the
cutout in the top ramp and the release arm assembly.
(g). Check for smooth operation of the digger swing
frame by releasing the clamp handle. This clamp can be
adjusted for position and tightness by releasing the
clamp several turns and re-positioning the hexagon head.
(g). Test the movement of the dolly.
Lower dolly with the bleed valve handwheel set at a
fixed position. The dolly should move slowly down
through it’s stroke. Engage digger and dig a 95mm
(3.75") hole. Spin auger until the tailings cease to come
out of the hole. Raise the dolly. It should lift the auger
smoothly out of the ground. If it fails;
- ensure the hole has been cleared properly.
- that the auger has not caught on an underground
obstruction.
- then look for the digger carriage fouling some part of
the frame.

SECTION 2.
OPERATING INFORMATION
2.1 HYDRAULIC CIRCUIT. The hydraulic circuit is shown in Fig. 2.1. Oil enters the
main control valve. If all control spools are in the neu-
tral position, oil passes freely through the valve and back
to the tank with little back pressure in any oil line. All
functions are locked and cannot move until the appropri-
ate control handle is operated.
If the dolly ram is raised to its up limit, the up damper
will arrest the motion and the pressure relief valve will
There is an intermediate position of the dolly spool
which allows the oil flow to be divided between dolly
and motor. This is useful when extracting a jammed
auger which can be rotated as it comes out of the ground.
A pressure relief valve fitted to the valve control bank
unit been factory set at 13800 kPa (2000 p.s.i.) and
should not be altered. The main pressure relief valve in
this hydraulic circuit provides protection for all valve
functions. A second relief valve is situated on the multi-
spool valve. This is set at maximum and therefore not
used.
Three point linkage - category 2 preferred.
- category 1 acceptable.
Tractor hydraulics preferred if suitable, namely;-
Pressure 15200 kPa (2200 p.s.i.) and higher preferred.
Pressure 10400 kPa (1500 p.s.i.) minimum.
Delivery, 23-45 litres per min. (5-10 g.p.m.)
Remote hydraulics or isolating valve essential.
Remote Jack Tapping, direct on tractor ram NOT SUIT-
ABLE. See also further explanation, 2.27.
Hydraulic power pack is available if tractor hydraulics
are not suitable.
2.2.2 RATED DELIVERY.
borne in mind that tractor manufacturers ratings are all
quoted at a high engine speed. When post setting, the
tractor is stationary with very little power required. A
"fast idle", say, of 1200 to 1400 r.p.m. is suitable and the
rated delivery should be lowered in proportion to the
engine speed. This is important, for some modern trac-
tors have rated deliveries higher than the acceptable
maximum of 45 litres per min. (10 g.p.m.). Also don't,
be confused between American (U.S.) gallons min. and
British (Imperial) gallons min. One Imp. gallon equals
1.2 U.S. gallons. All gallons quoted in this text are Im-
perial gallons.
The relief valve is factory set to 13800 kilopascals (2000
p.s.i.) which should be lower than the relief valve setting
for the tractor hydraulics.
Allowing the dolly to fall will discharge oil freely into
the tank. However, if the dolly is stopped in mid-flight
the squelch valve will dissipate the energy and bring the
dolly safely to rest. The squelch valve is factory set to
17,900 kPa (2600psi). Oil returns through the manifold
to the tank.
Controlled slow down-feed of the dolly (to control the
descent rate of auger drilling) is obtained by adjusting
the bleed valve. Oil is slowly released from the dolly lift
ram to the tank through the manifold.
If the digger spool is set to operate and the dolly is then
raised, oil is delivered to the ram and the motor stops.
Page 10
control valve and pipework are required to allow the
Multi-Sett to operate successfully. If your tractor has
such a system and you have been supplied with an open
centre Multi-Sett, a modification kit know as a John
Deere Kit is required. Contact your agent to arrange for
the necessary modifications.
employing a gear pump. The Post Sett hydraulics are set
up for this arrangement as standard. Supply can be taken
direct from the tractor remote oil supply or from the
optional power PTO pack. Return from the post set must
be direct back to tank, not via the tractor return remote
connection.
2.3 THE MAST. This consists of two 100 x 50mm channels and a tiltable
carrying beam. It is normally very durable, but can be
strained by careless driving. See 4.38, 4.39 for the
correct procedure. The carry beam is designed to
withstand the impact of a 38 kw (50 h.p.) tractor
reversing into a post. Very helpful for removing posts.
2.4 THE DOLLY. This moves on four Plastic slide blocks, to reduce
friction and minimise wear.
It is attached to the top of the ram by a self aligning joint
- see Fig. 2.42.
It is important to strike the post at a point on the
undersurface of the dolly as close as possible to the mast.
Repeated impacts on the outer extremities of the dolly
may cause undue strain. See para 4.39.
Under normal operating conditions minimal lubrication
of the slide blocks is required. If unused for some time or
very dirty, some dry lubricant applied to the inner mast
surface will give full performance. See Recommended
lubricants sect 3.3.
2.4.1 DISMANTLING AND ASSEMBLY.
The dolly may be removed vertically with a crane or by
laying the Post-Sett horizontally on a truck or loading
bay. In this case the digger and hydraulic ram unit
should first be removed and then it is quite easy to
manhandle the main frame on and off the dolly.
To disconnect the Thrust Nut assembly, use a 13mm
spanner to hold the ram rod. Unlock the nyloc nut.
When replacing be sure to lock the nyloc nut, thrust
washer and thrust nut as tightly as you can pull on a
couple of 18'' spanners.
NOTE; Never grip the rod with multi-grips and take care
not to burr the spanner flats.
2.4.2 THRUST NUT ASSEMBLY.
The dolly thrust nut position should be set to allow the
digger to be easily swung into position with the dolly
fully raised, see 2.4.3. When this position is attained the
thrust washer and nyloc nut should be tightened up
against the thrust nut, see Fig 2.42.
Fig 2.42 Dolly Ram Joint
Page 11
2.4.3 DOLLY HEIGHT.
The ''full up'' height is normally set with the Thrust nut at
its lowest point on the ram rod. If the digger to dolly
latches do not release from the dolly when the ram is
fully up then the dolly can be adjusted up to obtain more
latch movement. Using spanners, unlock the thrust nut.
Back off the nyloc nut about two turns. Using an open
end spanner to hold the ram rod, adjust thrust nut up or
down. Test and re-tighten. If the thrust nut is adjusted
up then thread locking compound (Loctite) must be used
to prevent the thrust nut from loosening downwards.
2.4.4 REPAIRS.
will require the removal of the dolly from the mast
frame. This is best done with the machine held vertical
and the dolly lifted by a crane or front end loader.
Alternatively the machine is placed horizontally with the
dolly on the ground. The frame is then supported and slid
off the dolly after removal of the two retaining bolts at
the top of the frame.
2.5 THE HYDRAULIC RAM. DESCRIPTION.
The ram and valve gear are built as a unit which may be
easily removed and replaced. The ram is a displacement
type. This means that there is no piston on the end of the
rod and the oil, in effect, merely "pushes on the end of
the rod".
2.5.1 FUNCTIONAL EXPLANATION OF RAM.
RAM FOOT is located in a loose box at the base of the
mast and the actual support is a "pimple" in the centre.
RAM ROD is attached to the dolly by a special joint
consisting of a conical thrust nut and rod buffer
assembly.
The purpose of this arrangement is to ensure that a direct
thrust is applied to the dolly (and the ram) with no side
load on gland or ram rod, even if the mast is a little
crooked or the dolly loose.
The whole ram assembly is prevented from rotating in
the mast by the square base and reaction link to take the
force of the operating handles, etc..
2.5.2 MAINTENANCE.
Check regularly that the dolly-ram joint is kept tightly
locked. Check the condition of the urethane Rod buffer.
Check that the ram gland nut is tight. Never grip the
piston rod with multi-grips on the polished section.
2.5.3 UP DAMPER.
The up damper brings the upward moving dolly to rest
gently at the top of its stroke. Oil is trapped by the
cushion piston in the annular space between the ram rod
and the damper cylinder in the gland. This space forms
the cushion chamber. Oil escapes slowly from the
cushion chamber smoothly arresting the dolly motion.
The action of this damper is independent of the valves,
but varies with the viscosity of the oil.
2.5.4 DOWN STOP.
A rubber-cushioned stop arrests the dolly at the lower
limit of its travel. In normal use, this should not be used
to stop the dolly, but the dolly should be "caught on the
oil", allowing the squelch valve to safely and quickly
slow the dolly's down travel.
2.5.5 SEAL.
The ram rod seal is simple to service, but care is
required. The following is the procedure:-
DISMANTLING - See Fig. 2.5.
a. Remove the rod guard.
b. Do not break any hydraulic connection.
c. Raise dolly and rest it on a post or block of wood so
that the top of the ram rod is accessible.
d. Relax oil pressure by opening bleed valve.
e. Undo nyloc nut and thrust washer on top of ram rod .
Drop rod into ram to clear dolly.
f. Remove keeper from bottom of dolly lift cylinder.
g. Remove reaction link on bottom of valve bank.
h. Unscrew ram cap.
i. Lever the bottom of the dolly ram cylinder out of it’s
retaining box and allow it move down by approx. 30mm.
J. Tilt ram clear of mast (towards tractor).
k. Rod and damper gland may now be withdrawn from
the ram tube using a twist and pull motion. Place a clean
rag around the rod, underneath gland assembly and over
mouth of tube to wipe rod as it comes out to save spilling
oil.
a. Grasp spanner flat of rod in vice.
b. Remove damper piston from bottom of ram rod.
Always remove the gland from the lower end of rod to
avoid seal damage by the thread. The seal can now be
easily removed from its cavity.
ASSEMBLY.
Assembly is the reverse of the above. Take care to avoid
damage to the seal as it is eased onto the sealing surface
of the ram rod. Check that the pressure and wiper seals
are oriented correctly. Keep the high pressure seal in its
seat with fingers during assembly and fitting.
2.6 MAIN CONTROL VALVE. A general description has been given under 2.1
The valve is connected through a high pressure oil port
to the dolly ram. Occasionally check the tightness of the
union nut connecting the valve to the oil port.
2.6.1 JACKING SCREW.
Note that a jacking screw between the ram tube and
valve mounting plate is used to position the valve with
respect to the oil port. If the valve is removed from the
oil port, ensure that the jacking screw adjustment is
checked when re-assembling. The jacking screw should
support the weight of the valve bank before the union nut
is tightened.
2.6.2 TO ADJUST THE RELIEF VALVE.
This is factory set at 13.8 m.p.a. (2000 p.s.i.) and should
not normally require any further adjustment. If attention
is required a pressure gauge will be required to indicate
setting. See Sect 5.2. A Tee fitting will also be required.
a. Undo and remove the dome nut located near the high
pressure supply entry hose.
c. Adjust the pressure using a screw driver by either
screwing the threaded adjustment needle into or out of
the valve body. Screwing in will increase the pressure,
screwing out will decrease the pressure. Only a small
amount of adjustment should be attempted (say 1/2 to 1
turn) and then the pressure checked.
d. Re-tighten the lock-nut once the pressure setting is
obtained and replace the dome nut.
e. Never screw the relief valve spindle all the way home,
as this will prevent the overload working and the tractor
pump could be ruined.
f. If correct pressure setting cannot be obtained then the
fault is normally in the tractor hydraulics (ie., tractor
relief valve, worn pump, etc.).
2.6.3 BLEED VALVE.
The bleed valve is used to provide a slow descent by
exhausting oil from the dolly ram under pressure back to
the tank at an infinitely variable hand-controlled rate.
The squelch valve limits pressure peaks in the ram
hydraulics is also incorporated in the bleed valve body
2.6.4 THE KNACK OF OPERATING.
If the dolly is raised and stationary, a slowly applied
steady pull on the dolly handle will permit the dolly to
fall slowly. If the lever is pulled smartly (but not
necessarily hard) free fall will be achieved. Do not use
this method for drilling as the sudden movement could
damage the auger.
a. Operating the handle to "lower" smartly, but not hard.
b. When steadily "stroking", "lower" just before dolly
reaches top of mast.
This knack is quite easily acquired and is important for
smooth operation and long life of your machine. If there
is a bang or the machine jumps up when the dolly
reaches the top of it’s travel then you have not got the
knack yet.

2.7.4 ADJUSTMENTS - PLUMBING THE AUGER.
2.8 LEVEL SET. The level set is an aluminum casting with two level vials
set at right angles. It is fitted and adjusted correctly at
the factory. (See Fig. 2.8)
Keep the level tubes covered when the machine is not in
use. The liquid will fade in prolonged sunlight.
2.8.1 Level Set Adjustment
If the level set should work loose during use it can be re-
adjusted:
a. Using a good carpenter's level placed against the
flange of the mast channel, plumb the Multi-Sett fore
and aft. Using the adjusting screw, place the level set so
that the fore-and-aft bubble reads level. Hold the
assembly firm with finger pressure on the mounting
screw while making this adjustment. If necessary the
lock-nut should be removed and placed underneath the
casting.
b. Repeat this for the side tilt. This time placing the
carpenters level against the side of the mast. Repeat the
bubble adjustment for the side tilt bubble. The for/aft
and side to side level adjustments are entirely
independent.
c. When the level set has been positioned true, lock the
lock nuts tightly and screw up the nut on the mounting
bolt. Make this just firm, too much pressure will bend
the casting and crack the tubes.

2.7.2 Auger position may be moved to and from the

wander if it meets an obstruction.
2.7.3 Digger engage latch D - To lock the Digger to the
underside of the Dolly. Firm engagement of this is
normally automatic. Adjustment is not normally
required, Significant wear will require the replacement
of the latches and pins. Oil pins occasionally.

2.9 SAFETY IN OPERATION. The use of the Multi-Sett for setting posts has a number
of hazards if not used correctly. The Multi-Sett has many
inherent safety features which protect the operator from
injury when the machine is operated correctly. It is
therefore very important that only trained operators are
permitted to operate the machine. The following
sections describe specific safety precautions that help to
produce a safe work method. Reference should also be
made to Section 4 “Operator Technique”.
2.9.1 GENERAL SAFETY INFORMATION
soles and steel toe caps.
Wear eye protection and gloves when splintery posts are
being used.
threads.
noise levels can be quite high.
When lifting the machine on the tractor linkage or tilting
it, make sure that the machine or its attachments do not
contact any part of the tractor, cabin or roll bar.
Take care when maneuvering on sloping or hilly ground.
Never move the tractor with the dolly up.
The machine is designed to be operated by one person
only. Do not operate the machine when another person is
close by. Warn other persons working in the vicinity of
the machine, not approach the machine while it is being
operated.
Perform the daily safety check described below:
It is good practice to leave the bleed valve open when
not operating the machine. This makes sure the dolly is
always down and prevents other untrained people raising
the dolly. Remember to close the bleed valve before
raising the dolly otherwise the dolly will not rise.
When moving or operating the Post Sett remain aware of
over head obstacles especially over head power lines.
Contact with live overhead wires can be fatal.
When performing other tasks while the Post Sett is
attached to the tractor or transporting from one worksite
to another disengage the PTO or oil supply to the Post
Sett to prevent excess wear and oil heating and to
minimise the risk of unintended operation of one of the
Post Sett hydraulic functions.
When work is completed and the machine operator will
not be in the immediate vicinity of the Post Sett, turn the
tractor off and take the key with you to prevent
unauthorised use by untrained people.
2.9.2 SAFETY IN DRILLING
there may be underground services in the vicinity.
Contact Dial before you Dig 1100 (in Australia) or the
relevant authority before proceeding.
system has a number features to ensure safe operation. It
relies on three springs in the digger carriage assembly
and one on the release lever. Ensure that these springs
are free to operate.
inexperienced operators. Always follow the following
safe operating tips:
Never touch any part of the auger with your hand or
foot while it is rotating.
Use care in starting holes in stoney ground. Stones
may have to be cleared to allow the auger to start.
Keep augers in good repair. Bent, broken or cut
flights must be repaired. Bent augers must be
straightened or replaced. Properly shaped cutters
start easily.
Always use the correct auger locking pin in the auger
chuck. If the original is lost, spares are available
from the factory. The locking sleeve must slide
loosely over the auger chuck and not jam on the pin.
Always check that the auger chuck slide cover is
down over the auger retention pin prior to drilling
each hole. Do not allow clay or sod to lift this cover
during drilling.
2.9.3 SAFETY IN DRIVING.
The safety chain and pinch bar are the best way of
guiding and handling the post during driving. Using
your hands or feet to guide the post during driving are
both ineffective and dangerous. See section 4.38 for
correct operator technique.
The dolly operator guard will prevent hammering
operation of the dolly unless it is in position. It also
effectively keeps the impact zone isolated from the
operator when driving. Ref Figs 2.931 & 2.932.

Never under any circumstances attempt to place your
hand or other part of your body above or on top of the
post, or allow any other person to do this. Serious injury
could result.
The operator guard is designed to allow full access for
digging and post installation. This is easily achieved by:
Dropping the dolly interlock lever into place (See
Fig 2.933)
you (See Fig 2.935)
and out of the way behind the machine (See Fig
2.936). The guard will latch in the stowed position
and the dolly lever down operation will be prevented
by the dolly interlock lever.
Closing the operator guard is simply achieved by:
Lifting the operator guard slightly to unlatch it
Swinging the guard around into position. It will latch
automatically on the top guard latch above the digger
carriage. (See Fig 2.937)
existing fence wire.
The dolly interlock lever is then lifted up to allow
hammering operation of the dolly. (See Fig 2.934)
The guard now effectively prevents access to the
impact zone during driving.
Do not lock the post chain around the post while driving.
This will cause the chain to bite into the post and stretch
or break it. The post chain is to be used with the pinch
bar for safe operation.
The operator guard is provided to separate the operator
from the dolly when driving and to prevent large chips or
splinters of wood striking the operator. It must be on the
machine and operational at all times.

The Multi-Sett augers are built from a steel flight, fitted
with a square drive chuck and a replaceable cutter.
Feed carefully into stoney ground. Make sure the Post-
Sett does not move while the auger is in the ground or it
may get bent.
Note: the cutter is driven on one wing by the auger
flight. This must remain in contact at all times otherwise
the cutter will be driven on the bolt hole which could
cause the shaft to break losing the cutter.
Double wing drives with restrictors are available for
rockier conditions.
3.1.1 CUTTERS
Cutters made from S.G. Iron or steel, may be built up
and repaired indefinitely with hard facing weld or car-
bide blocks. It consists of a shaft, two wings and a spade
centre bit. The standard cutter is a compromise in design
to suit the widest range of circumstances. It can be read-
ily modified for specialist needs such as rock or cracked
ground. The standard cutters are carbide tipped.
THE CENTRE BIT, OR SPADE presents quite a prob-
lem because the cutter moves slowly. Standard cutters
use an extended "spade" which is satisfactory for all
conditions except in some rock.
FOR ROCK Several types of cutter are available for
different conditions. Unfortunately trial and error seems
to be the best method of determining which is best for a
particular rock type.
A standard cutter fitted with an “AS4” centre bit is avail-
able that works for most soft rock conditions.
For difficult rocky conditions a Button Carbide design
cutter (Gold Cutter) in sizes up to 7” and a winged AS4
cutter for above that are available.
The important thing to remember when drilling in rocky
ground is to regularly check the condition of your cutter.
A damaged cutter will rapidly deteriorate. If your cutter
becomes damaged replace it with a spare and repair the
damaged one.
hole in almost any rock except for solid quartz, basic
granite and glacial moraine. It can be used as a pilot for
a Multi-Sett auger, or for blasting.
CLEARANCE.
The cutter diameter MUST be larger than the flight, say
6mm per 100mm (1/4" per 4") of diameter. If not, the
auger will constantly jam in the hole.
POINTS FOR SUCCESSFUL CUTTER REBUILDING
1. Note clearance in 3 places.
2. Grind to sharp edge but NOT flush with parent metal.
Rake - 0 degrees.
Clearance - 10-15 degrees.

eliminate slack caused by wear.
3.4 FAULT FINDING.
The Multi-Sett unquestionably takes the effort out of
fencing and makes a better job. It makes the setting of
fence posts both an easy and satisfying task, and driven
posts are tighter than rammed ones. To listen to the
"crunch" - "crunch" and watch the post smoothly slide
away out of sight into the ground gives great satisfaction,
especially if you were on the driving end of a bar and
shovel the previous week.
4.1.2 SKILL STILL NEEDED.
However, although the Multi-Sett makes life easy, like
reading or writing, you must acquire a good deal of skill
to use the machine to the best advantage: a new operator
will first find the machine slow and have trouble getting
the posts straight and in line.
4.1.3 GOOD OPERATOR IS VITAL.
If you have someone at hand to tell you all the wrinkles
and warn you of all the pitfalls, you can learn most of the
skill in half a day. If you have to find out for yourself it
takes longer. The purpose of this section of the handbook
is to help you to find out. You can become a good oper-
ator with care and attention to detail.
4.1.4 NEW SCOPE FOR FENCES.
Not only does the Multi-Sett make post-setting a pleas-
ure and set posts tighter, but because of the ease and
simplicity of the task it invites you to improve your fenc-
es by the use of new methods and designs. This is the
subject of Part 4.4 of this section. By "improve", is
meant that you can make your fences cheaper, stronger,
and more versatile.
In buying a Munro Multi-Sett you have shown a good
deal of courage and are to be congratulated. You feel
you have outlayed a lot of money: the returns are uncer-
tain and you don't yet know how much it will cost you to
keep the thing going. The manufacturers are confident
your doubts will be satisfied.
4.1.6 DON'T STOP HERE.
You will still need more courage to change your designs
and methods of fencing: this is especially so if you are a
contractor. Part 4.4 of this section may interest you.
4.2 WHAT YOU MAY EXPECT TO
ACHIEVE. 4.2.1 THE GROUND - ALL SOILS IN ALL WEATH-
ERS.
You can drive posts into all types of soil and clay. Dry-
ness and hardness are no hindrance and in the height of
summer you can drive posts as tightly as if they grew
there. In the wet, so long as the ground will carry the
weight of your tractor, you can keep going, and go
quickly too: the Multi-Sett has been used in 150mm (6")
of running water to drive 2700mm (9') railway sleepers
1600mm (5') deep. A fallen fence was then pulled up to
these strainers and then made stock proof before the
flood subsided. Care must be taken, however, when
working in wet and slippery conditions.
ROCK AND GRAVEL IS A LITTLE SLOWER.
Naturally, you can't treat rock like soil, but you will be
amazed at what you can do. The going is slower, you
must drill a hole, and your post may only be a shade
larger than the hole. Crooked posts cannot be pushed
into line.
The easiest rock structures to work in are the uniform
soft ones such as shales, as found in the Central High-
lands of Victoria. Holes may readily be augered up to
152mm (6") diameter (larger, with care and special
equipment) rapidly and to full depth. A hardwood post
should not exceed the hole diameter by more than about
12mm (1/2"). Next to shale in ease of working come the
gravels. Fine gravels pose no problem but large stones
catch on the auger and make drilling frustrating. The
size of the post is not restricted in gravel as much as in
uniform structure of rock.
floating flints cause the same trouble as gravel.
A "Proline" type auger may be used as an alternative as
the Multi-Sett Motor is strong enough to drive it.
GRANITE AND BLUESTONE JUST DRILLABLE.
Large pieces of granite and bluestone may be drilled
43mm (1.75") diameter using the rock auger at rates
from 50mm (2") to 200mm (8") per minute. This hole is
sufficient to take 37mm (1.5") pipe or a steel post: if a
larger hole is required this one may be opened out with a
specialized button style rock tip (Gold Cutter) up to 6”,
but the drilling will be very slow and difficult.
SECTION 4.
OPERATOR TECHNIQUE.
Page 20
Basic granite and quartz cannot be drilled with the Multi-
Sett.
"Floaters" of any rock (usually bluestone) are most trou-
blesome because usually the auger strikes a sloping sur-
face and will not "start", and the hole, if drillable, is
limited to 43mm (1.75") diameter anyway. In such
country, the auger can only be used as a probe to select
post location free of rock.
4.2.2 THE POSTS -
ALL WOODEN POSTS.
The Multi-Sett was designed specially to drive split posts
and strainer posts as well as round posts. All types of
wooden posts may be driven, up to 3050mm (10 feet)
long and up to 380mm (15") in diameter.
10ft. long posts have to be driven with the Multi-Sett
raised on the extension legs. It is not recommended that
the machine be operated off the ground.
STEEL AND CONCRETE POSTS TOO.
Pieces of railway line, "I" beam, pipe and star posts may
also be driven satisfactorily. Concrete posts may be
driven if a suitable resilient cap is made.
4.2.3 SPEED AND ACCURACY WILL SUIT THE
MOST EXACTING LAND-OWNER.
accurately for all practical purposes. The Multi-Sett has
been demonstrated to the satisfaction of some extremely
fastidious customers with perfectly acceptable results.
HOW STRAIGHT IS "STRAIGHT"?
one expects to align them, either along their centres or
along one good face "perfectly accurately". If such a
row is later tested with a taut line, it will be found to be
far from perfect. With the Multi-Sett it is quite practical
to create just as good alignment as in hand-setting. Indi-
vidual posts may certainly be positioned within 6mm
(1/4") of desired position at foot and top but practical
fencing does not demand anything like such accuracy.
Except for gate posts, a more practical accuracy to aim
for (using any method) would be:-
SPEED.
c. The speed of working, as may be expected, varies
enormously. With soft ground, pre-pointed round posts
and a guide wire laid out you may achieve better than
one post per minute at 13.4m (44ft) spacing, which is
one hour, fifteen minutes to the kilometre of posts (two
hours to the mile). If the ground is hard you may expect
to set one post in less than 3 minutes. Strainer posts vary
even more widely, but 5-7 minutes may be regarded as
typical for 200 - 250mm (8" - 10") x 2300mm (7"6")
hardwood posts.
Apart from straight farm fencing you can use the Multi-
Sett for a lot of other things, for instance:-
Building yards.
Drilling for blasting operations.
4.3.1 NUMBER OF OPERATORS.
It is convenient to have two people on the job, but there
must always be only one person operating the Multi-
Sett or in the immediate vicinity for safe working. A
number of owners prefer to work single-handed with
satisfactory results.
4.3.2 SETTING OUT THE LINE.
Set out the line by the method you prefer. The simplest
way, however, is to run out a guide-wire to mark the
line.
This should be strained up between sighters just beside
the desired line. "Flip" the wire until it lies straight and
lay logs or stones on it in the hollows. The posts should
be driven 1" or 1/2" clear of the wire so that if a small
mistake is made, the wire is not deflected and the next
post consequently put in the wrong place.
If single posts are being set use the provided pinch bar to
mark the exact spot and back the machine up this mark.
4.3.3 DRIVING THE TRACTOR.
The simplest way is to drive along the line, straddling the
guide wire. This is also the quickest way, and the post
spacing may be measured by trailing a knotted rope or
chain from the Post-Sett. See Fig. 4.32.
In irregular country, or if it is preferred to sight the posts,
the tractor may be driven across the line. See Fig. 4.33.
If the ground is steeply sloping or very irregular, it is
sometimes wise to place the tractor at an angle to the line
facing exactly down-hill and reverse into position.
The rear mounted side shift option assists enormously in
efficiently setting out posts with one operator. This al-
lows the tractor to be driven beside the line and the side
shift used to obtain exact alignment.
4.3.4 TO DRILL OR NOT TO DRILL?
That is the question! It must be decided from experi-
ence. Usually, as one becomes proficient with the Multi-
Sett, one prefers to drill holes where in early days one
would have driven without a pilot hole. Time spent drill-
ing saves time in pointing the post, saves time driving
and saves time in straightening up crooked posts.
4.3.5 SIZE OF HOLE.
In plastic ground this is not important, a 95mm (3.75")
hole will suit a 100mm (4") or a 225mm (9") post. In
hard loam a 175mm (7") post is tighter driven into a
150mm (6") hole than into a 95mm (3.75") one. In shale
At ground lev-
Height ---- 6mm (1/4")

or hard subsoil the hole must not be much smaller than
the post, say 25mm (1") of diameter at most, preferably
12mm (1/2"). See also 3.1.3.
4.3.6 HOW TO DRILL A HOLE.
Position the machine firmly on the ground. Plumb the
machine carefully, using the tilt controls.
Having decided on post size (diameter) and auger diame-
ter (from 4.35), set the swing frame to ensure that the
post to be driven will be positioned correctly with re-
spect to the mast (see 4.39). This setting of the swing
frame will also determine the starting position for the
auger point with respect to the base of the mast.
Using the bleed valve, lower the auger (no rotation yet)
to the ground, and allow the auger point to rest on the
ground. Close the Auger Feed (bleed) valve.
Start the auger in the correct rotation and slowly open
the Auger Feed (bleed) valve. In soft ground, the auger
will bore a hole correctly aligned where you first posi-
tioned the auger point. Use the Auger Feed (bleed) valve
to control the rate of down feed. If you need to increase
or decrease the auger speed, do this by adjusting the
tractor revs.
As necessary, clear soil from the hole by raising the ro-
tating auger and spinning off the dirt at the top of the
hole.
valve to arrest the feed. While the auger is rotating,
press it into its true position with the back of a spade.
Stick the point of the spade into the ground close to the
auger and then press back using handle as a lever. While
still holding spade, slowly let the auger in a bit further.
And so on. If this does not stop the auger wandering,
stow the digger and dig away the obstruction by hand or
move the hole position.
Alternatively, stow the auger and dig away the hard crust
causing the deflection, then restart the auger as first de-
scribed.
If the soil gets softer at depth, it is not necessary to dig
full depth, and cleaning out is unimportant. If the soil
gets harder at depth, the hole should be drilled 300mm
(6") deeper than the post to be set, and must be cleaned
out. Regulate auger feed to allow tailings to clear.
The rock auger is hard to start. Chip a little depression
in the rock with the crowbar and start carefully. Run at
less than 100 r.p.m. and feed gently. The motor is strong
enough to break the rock cutter if it jams.
All cutters should be maintained in accordance with Fig.
3.13.
If the auger stalls out and stops, it is usually due to the
cutter hitting a root or piece of stone, or the auger being
fed too quickly. This will not harm the equipment as the
activating oil in the hydraulics bypasses the drive motor
through an automatic relief valve set at 2000p.s.i.
To start the auger again, turn off the bleed valve control-
ling the feed rate and the auger motor and give the dolly
lift handle a bump. This may allow the cutter to clear the
obstruction and the operator may then start the motor
again and begin feeding. It may be necessary to turn the
feed tap on and off constantly until the obstruction is
passed, whereupon normal feed methods may be adopt-
ed.
If the jam cannot be cleared by the above method, then
turn the feed off, work the dolly lift lever on and off
repetitively and go into reverse with the auger motor.
Page 22
Do not reverse the auger motor if there is significant
downwards pressure on the auger.
Once the auger is running freely in reverse, go into for-
ward mode with the auger and commence feeding again.
Remember that if you do not see soil coming out of the
hole you are drilling, you are feeding too quickly.
Sometimes a change in tractor revolutions will improve
efficiency.
If the going is difficult, then consider using heavier duty
augers with double start flighting in lieu of the standard
design. Remember that you can shear off the cutter stem
or break carbide tips by going into reverse without lift-
ing. You may also break off a cutter wing in forward
mode if the going is arduous.
Generally the standard augers and cutters are for medium
to easy going. Whilst standard augers handle 80-90% of
conditions, they are susceptible to abuse. A range of
Heavy duty Augers is also available for hard and contin-
uous going.
4.3.7 POINTING THE POSTS.
If a pilot hole is to be drilled, the point on the post is
unimportant. Some point is needed because a square
ended post will not necessarily follow the pilot hole and
shear the sides off the hole. This will fill the hole ahead
of the post instead of compacting the earth around it.
It is sufficient if the post is arrissed until the flat end is
roughly 2/3 the diameter of the pilot hole. If a pilot hole
is not to be drilled, the whole success of the driving de-
pends on the skill of the post pointer.
A post with a slight shallow lead will compact the sur-
rounding earth as it is driven.
4.3.8 DRIVING THE POST.
Lower the machine onto, or very close to, the ground. It
is not necessary to plumb the machine accurately. Place
the post about an inch clear of the mast. If a hole has
been drilled, this point should have been watched. If the
post has a bend in it, the bend should lie in the line of the
fence. The post is unlikely to be perfectly square on top,
and the high side should be placed nearest the mast.
Close the operator guard and steady the post with pinch
bar or roller guide and start it with gentle hits. The post
may start to go crooked. As soon as it does, guide it with
pinch bar, or pinch bar and chain. i.e. push the post back
into vertical position If the post is allowed to continue
crooked for even one or two hits, it will be impossible to
straighten it. The essential point is to pick up the misa-
lignment as soon as it deviates.
Continue driving to the desired depth.
Keep operator guard in place. IT IS NECESSARY.
Sometimes chips will fly (especially if top of post is not
square) and they come off at high speed!
4.3.9 AVOID JARRING.
The post and the Post-Sett must be positioned so that the
point of contact between dolly and post comes close to
the mast and on the centre line. See Fig. 4.39. The indi-
cation that this has been achieved is the deep "thunk"
noise and very little rattle when dolly strikes. A loud
crash and rattling of the whole machine results when the
point of impact falls outside the desired region.
Occasional failure to observe this precaution is inevita-
ble, and provided you don't mind the horrible noise, is
immaterial. Constant failure to observe this precaution
will lead to excessive wear and tear through the machine.
The reason for this is set out in the accompanying
sketches. Fig. 4.39-B to D.
Fig. 4.39B shows the dolly suspended at rest. The ar-
rows indicate the pressure of the slide blocks on the
channel.
Fig. 4.39C shows the dolly striking a post well inside its
centre of gravity. If it were not for the slide blocks, the
dolly would overturn, top outwards, and therefore press-
es very heavily on the channels, as shown by the large
arrows.
Page 23
NOTE WELL that the force on the channels is still in the
same direction; there is therefore very little noise. This
results in a clean hit.
Fig. 4.39D on previous page shows the dolly contacting
the post outside its centre of gravity. In this case it will
be seen that the dolly tries to overturn, bottom outwards,
and now presses heavily on the channels in the opposite
direction from previously. As the slide blocks move
across the small clearance in the channels they make a
loud noise and rattle the whole machine.
4.4 FENCE DESIGN. 4.4.1 GUIDE WIRE A GREAT HELP.
If a guide wire can be laid out it is definitely the simplest
way of aligning the posts. Where wires are to be stapled
this is straightforward, and where wires are to be reeved
through holes, the guide wire may be cut at the centre of
the line and then pulled through.
4.4.2 SOIL MECHANICS.
In many agricultural soils it is only the top 450mm -
600mm (18" - 24") of soil which gets wet and dry. Be-
low this depth, soil remains uniformly damp throughout
the year, and if posts can be set in, or partly in this zone,
they will be much firmer than shallow set ones.
4.4.3 LINE POSTS - USE FEWER AND LONGER
BUT DRIVE DEEPER.
One consequence of the foregoing paragraph, plus the
ease of setting with the Multi-Sett is that you can save
money by using fewer line posts. They can, with ad-
vantage, be longer, and set deeper, say 750mm or
900mm (30" or 36") deep instead of 600mm (24").
4.4.4 STRAINER POSTS.
2900mm (8' to 9'6") are better.
4.4.5 CURVED FENCES.
4.4.6 TIED GATEWAYS.
A very effective gateway may be produced by using two
driven gateposts, 1200mm to 1500mm (4 to 5 feet) deep,
tied to each other 50mm (2") below ground level with a
steel band - either 12mm (1/2") rod or 4 turns of no. 11
h.t. wire. This is quicker, cheaper and far more effective
than a stayed gateway. Provided the point of the post is
in solid earth, the assembly can never move. Posts
should not be less than 200mm (8") diameter. See Fig.
4.46.
Multi-Sett would be well advised to familiarise
themselves with these. The end assembly is the most
important part of the fence.

TOOLS REQUIRED
5.1 SPECIAL TOOLS. The special tools and test methods shown here should
only be used by a person who has;
A knowledge of the theory and operation of hy-
draulic systems and tractor hydraulics.
Mechanical and fitting skills.
5.11 PRESSURE TESTER.
This is shown in Fig. 5.11. It is indispensable when fault
finding. Connect up the Post-Sett with the Pressure
Tester inserted in the high pressure line feeding the Con-
trol Valve.
TO CHECK TRACTOR OVERLOAD PRESSURE.
Turn on the oil supply. Slowly close the valve on the
tester and note maximum pressure. Immediately re-open
valve.
If the pressure was maintained until the valve was re-
opened, the tractor is equipped with a relief valve and the
pressure observed was the tractor relief pressure.
If the pressure dropped back suddenly of its own accord,
without the need for the valve to be re-opened, then the
tractor was equipped with an "unloading valve", and the
pressure observed was the unloading pressure. This
reading is rather tricky, and the measurement should be
repeated twice. The highest reading obtained is the cor-
rect one. Turn the valve very slowly as high pressure is
approached.
(CONTROL VALVE).
Raise dolly. Hold lever to "raise" position. When the
dolly is steady at top of mast, read the pressure. If this
reading is less than the tractor pressure, it is the control
relief pressure. If it is the same as tractor pressure, then
probably the control valve relief is not operating; one or
other must be altered. Adjust, if necessary. Control
valve as in 2.62.
provide you with a post driver which is:-
Very effective in operation.
This performance can be achieved with a little regular
attention to:-
Cleaning and lubrication. (See Section 3.3).
Wherever possible, wear has been eliminated by careful
design. Where moving parts are a necessary part of the
functioning of the machine, life of components has been
prolonged by provision for adequate lubrication and
replaceable parts.
The following wearing parts are kept in stock for re-
placement purposes. Any servicing involving major
machine parts not listed should be discussed with the
factory.
machine serial numbers must be quoted when ordering
spares, in order to correctly identify parts.

SECTION 7.
SET TELESCOPIC UNIT. For the operating, maintenance and safety information,
refer to the appropriate sections of the manual covering
the STANDARD Multi-Sett machine. The additional
information specific to the TELESCOPIC Tele-Sett is
contained in the relevant sections of this supplement.
The telescopic mast enables the user to drive posts up to
3.4 m (11ft-2in) in any fencing material; steel, concrete,
or timber, up to 380 mm (14 in) in diameter.
In retracted form, the machine is little taller than a stand-
ard MultiSett. This flexibility is obtained at no sacrifice
to driving power, rigidity or stability – the longer post is
driven with the same power as with a standard machine.
The unit is engineered so that there is no deflection of
the mast on extension or under load. – an essential factor
in the swift, safe driving of long posts.
7.1.1 SUITABLE TRACTORS
Any larger category 1, or 2 linkage tractor with remote
hydraulic tapping. Minimum oil flow requirement is 20
– 25 litre per min. (5 gall per min) at 138 Bar (2000 psi.).
Heavier tractors are required for mounting the telescopic
Tele-Sett. Those of 40K.W. (60H.P.) and larger are
generally suitable.
Smaller tractors can be set up to take the TeleSett. For
example, by setting the rear wheels as far apart as possi-
ble, and by adding ballast weights to the front of the
tractor. Do not use on tractors which do not have this
facility, and do not use on tractors which have a narrow
wheel track. Tyres must have water ballast.
The tractor manufacturer must be consulted if there is
any doubt as to the stability of the tractor with the Tele-
Sett fitted. The following information will assist stability
assessment when travelling:
Position of centre of gravity behind linkage pins (Tele-
Sett in vertical attitude, Dolly lowered) - 270mm
Height of centre of Gravity above the upper lower link-
age pins with dolly down - 903mm
Height of centre of gravity above upper lower linkage
pins with Dolly up, Tele mast down - 1689mm.
The stability of the tractor may be severely compromised
if the machine is moved with the dolly up. All transport
movements should be with the Dolly in its lowered posi-
tion.
With the telescopic function retracted, the Tele-Sett op-
erates in exactly the same way as the Multi-Sett. In this
respect, all information contained in Section 2 of the
standard manual applies.
The hydraulic circuit as depicted in figure 1 applies, with
the exception of an additional valve unit added to func-
tion the telescopic mode. A flexible, large capacity, high
pressure hose, connecting the control valve to the tele-
scoping ram, replaces the Multi-Sett direct pipe connec-
tion, and allows the dolly, in extended mode, to be con-
trolled in the same manner as the MultiSett from the
standard operator position.
Auger drilling of holes is performed in the collapsed or
Tele mast down mode.
The digger should be engaged with the dolly only when
the telescopic mast is in the full down position. The
digger should then engage and disengage from the dolly
easily. If trouble is experienced, check first that the
digger engagement parts are lubricated with grease; then
check that the base of the telescopic frame is resting on
the down stop (metal to metal) and is not impeded by
accumulation of dirt or mud. A further check is to en-
sure that wear in the slide blocks fitted to the dolly or
telescoping mast is not the cause of the misalignment in
the engagement digger to the dolly. After checking these
points, any adjustment of the dolly height should follow
Section 2.43 in the standard Multi-Sett manual.
When the digger is engaged under the dolly, do not raise
the telescopic mast until after the digger has been proper-
ly stowed. Do not lever or mechanically force the digger
carriage into the operating or stowed position. It should
attach and stow without undue force. If not, there is
something wrong. Forcing the unit may distort parts
which will then require workshop repair
Page 30
Section 2.44 in the Standard Multi-Sett manual describes
how occasional wear in the dolly slide blocks can be
taken up by fitting special spacers. This procedure
should be followed also for the dolly on the telescopic
model.
It is important to regularly lubricate the slide blocks with
a dry lubricant. See Recommended Lubricants in section
3.3.
If necessary, a similar procedure can be followed for re-
fitting similar slide blocks on the elevating frame, alt-
hough in normal use these are subject to little wear. Lu-
bricate these slide blocks regularly.
An occasional dab of grease on the contact points of the
digger carriage, latch and dolly, will greatly assist easy
operation and stowing of the digger. See the lubrication
recommendations in section 3.3.
It is important to maintain the fit of the dolly in the
frame. A loose dolly will create sideways forces on the
frame when hitting an
