The control levers are direct-acting. The boom has hydraulic parallel holding of the feeder, which means that all the holes can be drilled parallel to each other. Each cyl-inder is marked using a colour coded system where the colour of the cylinder corre-sponds with the colour marking on the lever that controls it. This simplifies learning and makes it easier to directly select the correct direction for each lever. The speed of the cylinders is proportional to the travel of the levers, which makes controlling the boom smooth and adaptive.

Checks1. Check the oil level in the hydraulic oil reservoir and top up as necessary. See

maintenance instructions, Hydraulic systems: Changing oil.

2. Check the oil level in the lubricating oil tank and top up as necessary.

Setting up the rigWith each new setting-up of the rig it is essential that it is correctly aligned. See Safety, Rig stability.

1. Manoeuvre the rig to the where drilling is to take place. Position it at right angles to the centre of the tunnel face, parallel to the direction of drilling. It must be pos-sible to manoeuvre the booms past the parts of the rock face that protrude the most.

2. Set up the rig on its jacks. Start with the front jacks and then the rear jacks until the rig is level (observe the spirit level in the cab).

NoteThe following points are important to observe: The rig must be raised so that none of the wheels is in contact with the ground. The rig must be standing steadily while drilling to avoid disturbing the naviga-

tion.

Operators instructions 9. Drilling2. Start the hydraulic pump with start button (S105).

3. Make sure that the selector lever (Lrb) for small/reaming holes is in the desired position. Option.

4. Position the boom and feeder for drilling and apply the feeder dowel firmly against the rock. See operator instructions, Boom handling.

5. Start water flushing with lever (Law). Make sure the valve is fully open.

6. Start rotation drilling (rotation left) by moving the lever (Lr) forward.

7. Collaring: Start low percussion pressure by moving lever (Lh) to the centre posi-tion. At the same time, start forward feed by moving lever (Lf) forward. A low feed force is automatically attained.

8. Full drilling: Start high percussion pressure by moving lever (Lh) to its foremost position once the drill bit has entered the rock. A high feed force is automatically selected.

9. Once a hole is drilled, the percussion unit is automatically switched off and reverse feed is automatically engaged. When the rock drill has reached its rear end position, move the rotation lever (Lr) and feed lever (Lf) to their neutral positions.

10. Switch off water flushing with lever (Law).

11. Repeat steps 4 to 10 above for the next hole.

Cease drillingStop the drilling by moving the drilling levers to neutral position.

In the event of drill jamOn rock drills equipped with extraction unit (COP 1838 MEX) this must be started as follows:

1. Activate feed reverse by moving the feed lever (Lf) backwards.

2. Start collaring by setting the percussion lever (Lh) in collaring position.

Important points to consider when using the extraction unit.

The extraction unit must not be used as an aid for example - To drill with inadequate flushing agent. - To drill with such a feed force etc. that there is a risk of repeated drill jams

(applies in particular with poor rock conditions).52

Operators instructions9. Drilling When using the release function, the front section of the rock drill heats up rap-idly. For this reason, use the extraction unit for short periods, max. 30 seconds, and then allow the rock drill to cool down for at least 30 seconds as follows - Active feed reverse, so that the oil can circulate through the extraction unit.- If possible, activate flushing in order to cool the front section of the rock drill.

The release function must only be used with high percussion pressure as a last resort to loosen jammed rods as it involves major stresses on the drilling equip-ment. Avoid using rotation together with the release function as the rod joints are tightened very tight!

Air blowing of drilled hole, option1. Stop the feed and rotation when finished drilling a hole.

2. Blow the hole clean for 5-10 seconds by moving the lever (Law) to is rearmost position.

3. Once air flushing is finished, move the rock drill back to its rear end position with control lever (Lf).

4. Position for the next hole and perform a new collaring.

Changing drill bit

Safety

Changing drill bit against rock face

N.B. Never start percussion with the drill bit free without any resistance.

WARNING Moving parts. Risk of personal injury, clothes can be

trapped. Switch off the rock drill rotation when

changing drill bits. Switch off hydraulic pumps if the

operator's panel is left unmanned.53

Operators instructions 9. Drilling1. Operate the feeder until the drill centre has good contact with the rock face.

2. Move the drill bit forward until it presses against the rock face and drill in about 5-10 cm.

3. Make sure the rotation lever (Lr) is in neutral.

4. Move the water flushing lever (Law) forward to cool the drill bit.

5. Start high pressure percussion and high feed force by moving the levers (Lh) and (Lf) to their foremost position for three to five seconds.

NoteIf an attempt to release the drill bit fails due to insufficient percussion pressure, use button (Blb) on the operator panel to attain high percussion pressure.

6. Return the rock drill to its rear position by pulling lever (Lf) towards the operator without rotation.

7. Unscrew the old drill bit by hand and replace with a new one.

Changing drill bit in bottom of hole

N.B. Never start percussion with the drill bit free without any resistance.

1. Cease drilling approx. 10 cm before the hole is fully drilled by moving the drilling levers to neutral position.

2. Make sure the rotation lever (Lr) is in neutral.

3. Move the water flushing lever (Law) forward to cool the drill bit.

4. Start high pressure percussion and high feed force by moving the levers (Lh) and (Lf) to their foremost position for three to five seconds.

2. Always be observant for any water leaks from the rock drill.

3. See maintenance schedule, Rock drill.

System1. Make sure there are no fault indicator lamps on the electric cabinet. Attempt to

rectify any faults or call for service personnel.

2. Check the pressure gauges on the operator panel. If they suddenly show abnormal values, the drilling must be stopped immediately and the cause investigated.

3. Check the oil level in the hydraulic oil reservoir and top up as necessary. See maintenance instructions, Hydraulic systems: Changing oil.

4. Check the temperature of the hydraulic oil on the thermometer on the hydraulic oil tank. The temperature should be 30-60C during continuous drilling.

CAUTION Call for service personnel if a fault should

occur in the hydraulic, pneumatic or electrical systems while drilling is in progress.

Do not experiment with the systems. Simple faults can be made worse with risk

of personal injury.55

Operators instructions 9. Drilling5. Make sure there is oil in the lubricating oil tank and top up as necessary.

Figure: Lubricating oil tank

Hoses and couplings1. Make sure the percussion hoses to the rock drill do not vibrate abnormally. Vibrat-

ing hoses indicate malfunctioning accumulators on the rock drill. Stop drilling immediately and check or replace the accumulator. See maintenance instructions, Rock drill.

2. Ensure the hoses do not get trapped or jammed.

3. Make sure there are no leaks in hoses or couplings. Tighten or change leaking cou-plings and hoses.

SettingsFeed pressure

Setting feed pressureThe feed pressure must be adjusted to the drill bit diameter, bit type, percussion pres-sure, rock conditions, etc. It must be set so that the threaded joints of the drilling equipment do not come loose, causing abnormal wear or damage. Nor must the pres-sure be set too high, subjecting the drill rod to abnormal loads or increasing the risk of jamming.

When drilling in loose rock, it may be necessary to reduce the percussion pressure so that the feeder's maximum feed pressure is not exceeded.

NoteThe RPCF valve (V1a) must be disengaged while the feed pressure is adjusted. This is done by screwing the RPCF valve (V1a) clockwise as far as it will go.If the rig is equipped with a special reaming kit (option), there will be an RPCF valve for reaming (V1b). This must also be disengaged while the feed pressure is adjusted. (V1b) is to be disengaged in the same way as valve (V1a).

Anti-jamming protection

DescriptionThere are two types of anti-jamming protection:

RPCF (feed control) Return movement of the feeder, usually simply called anti-jamming

The anti-jamming protection features are integrated and therefore interact. The fol-lowing is an example to show what happens when the protection is activated and what the result is.

If the drill bit tends to jam in the hole due to e.g. joints in the rock, the rotation pres-sure will start to increase and the feed pressure to drop successively to around 40 bar. If rotation pressure continues to rise, the feed will change direction and the rock drill will return. As the rotation pressure subsequently drops, the rock drill will change direction once more. If the drill bit still tends to jam, this procedure will continue until the bit has passed through the joint in the rock.

RPCF feed controlRPCF (Rotation Pressure Controlled Feed) is an anti-jamming device that is engaged in the following circumstances:

The drill bit tends to jam in the rock

Rotation pressure increases

Broken/worn drill bit

Low hydraulic oil temperature

V17

V812

50 0

136

1261

Operators instructions 9. DrillingWhen RPCF is activated, the feed pressure will gradually drop until it almost reaches zero.

Feed (rock drill) return movementWhen RPCF is activated and if the rotation pressure still rises then the second anti-jamming device will engage. This means that the feed will change direction and the rock drill will reverse. When the rotation pressure then decreases the rock drill changes direction again and moves forwards.

Setting the anti-jamming protection

General

When adjusting the anti-jamming protection, the following settings must be made in order:

Setting the feed return movement

Setting RPCF, small hole

Setting RPCF, reaming hole (if the optional reaming hole kit is installed)

When the RPCF is to be set, there are two ways to proceed:

Setting RPCF during drilling Setting RPCF in a workshop

Setting the feed return movementNoteThe hydraulic oil must be at normal operating temperature before setting.

Valve (Vaj) must be used to set the rotation pressure at which the rock drill is to change direction.

1. Check the rotation pressure during normal drilling. The rotation pressure can be read on pressure gauge (Gr).

2. Connect a pressure gauge to pressure test outlet (G3).

3. Undo the lock nut used for valve (Vaj).

4. Adjust the set screw to 30-40 bar above the normal rotation pressure. Read the pressure from a pressure gauge connected to pressure test outlet (G3).

If the valve is adjusted too low, the rock drill will change direction too early.

If the valve is adjusted too high, the rock drill will not change direction and the risk of jamming will increase.62

Operators instructions9. Drilling5. Tighten the lock nut.

6. Now set RPCF before making any further settings.

Setting RPCF during drillingNoteThe hydraulic oil must be at normal operating temperature before setting.

Normal rotation pressure settings for drilling are 35-50 bar for small holes and 40-50 bar for reaming holes. If the pressure rises above normal, there is risk that the drill steel will jam. The RPCF valve must therefore be activated if the normal rotation pressure rises by about 20 bar during drilling.

Valve (V1a) affects the rotation pressure at which the feed pressure will start to be reduced for a small hole drill bit.

Valve (V1b) affects the rotation pressure at which the feed pressure will start to be reduced for a reaming hole drill bit.

1. If the rig is equipped with a reaming kit (option), make sure that lever (Lrb) is in the correct position.

2. Find some homogeneous rock in the area being drilled.

3. Screw in the adjusting screw used for the RPCF valve all the way.

4. Collar the hole firmly and proceed to full drilling at a suitable feed pressure.

5. Read the rotation pressure on the pressure gauge (Gr).

6. Screw out the adjusting screw used for the RPCF valve until the feed pressure starts to drop.

7. Screw in the adjusting screw used for the RPCF valve about one turn.

One turn corresponds to about 20 bar of rotation pressure.

A 20 bar increase in the normal rotation pressure is needed during full drilling before the RPCF function will start to reduce the feed pressure.

8. Tighten the RPCF valve lock nut.63

FAM I with angle indication FAM II with angle indication and hole depth measurement

Angle indication involves measurement and indication of the feeder's direction. The system calculates the deviation from the defined reference direction, which the feeder's direction should give with a full depth drilled hole. The deviation is pre-sented in cm.

For the system to present the correct values, the user must specify a reference direc-tion and a length for a full depth drilled hole (not drill steel length).

The system also shows instantaneously the attained hole depth when drilling, if equipped with hole depth measurement

Figure: Working menu1 Zeroing hole depth measurement2 Reading of user defined reference direction3 Selection of reference direction4 Maximum hole depth5 Vertical deviation6 Feed direction7 Measured hole depth

The feed direction is shown graphically in the form of a target where the bull's-eye represents the starting point of the hole. The target shows where the hole finishes up in the bottom of the blast. If the feeder is directed according to the reference direc-tion, the hole will end up in the centre of the target. Otherwise, there will be a devia-tion that is indicated with a line (6).

According to the figure above, the hole will deviate about 7 cm both vertically and horizontally.

The angle display will always be based on drilling the maximum depth of hole, i.e. according to the value at (4). Maximum hole depth must therefore be set before angle display will work.

The type of reference direction must also be chosen (3). If the rig symbol is chosen, the system will use a predefined reference direction, i.e. the rig's longitudinal axis. If the tunnel symbol is chosen instead, an optional reference direction can be defined.

If the hole depth measurement option has been chosen, the measured hole depth will be displayed (7). This also means it is possible to zero hole depth measurement (1).

Change the value for the maximum hole depth as follows:

Display the menu for setting the maximum hole depth. Place the cursor on the box with the numeric value and press Enter. Use the right and left arrow keys to place the cursor over the digit (ones, tens or

hundreds) that is to be changed. Change the value with arrow up (increase value) or arrow down (decrease value). When the entire value (all three digits) is correct, press ENTER for the system to

save the new value.

Reference directionThere are two alternatives for reference direction, Rig and Tunnel .

Rig Rig means that the longitudinal axis of the rig will be used as reference direction.

APC 50 (Automatic Powershift Control

Description of operationThe APC 50 shift control is used to prevent incorrect downshifting and changes in direction of travel that otherwise could damage the transmission.

Speed reduction must be done by releasing the accelerator and using the service brakes. Reducing speed by downshifting can damage the transmission and is there-fore prevented with APC 50.

The direction of travel, from forwards to reverse or from reverse to forwards, may only be changed while the rig is stationary. Changing the direction of travel while the rig is in motion can damage the transmission and is therefore prevented by APC 50.

Changes in the direction of travel and downshifting can be done at the following approximate speeds.

Table: Speed limits for downshifting and changing direction of travel

When attempting to downshift or change direction of travel at the wrong speed, the right-hand point of the display will flash to make the driver aware that this measure is not allowed and will therefore be prevented by APC 50.

Every attempt to make a forbidden gearchange is registered by APC 50 and is saved in its internal memory.
