2.4 Testing

All power units are tested at thefactory and their flows and pressuresare recorded on the test report,which is shipped with the power unit.Testing of the power unit is notrequired unless it is damaged duringshipping.

Always perform “before startupprocedures” found in section 3.3before testing. PortaCo HydraulicTester, Part Number T-00016-XX-0is recommended for all tests.

a. Set the hydraulic circuit to “OFF.”b. Connect hydraulic hoses to the

power unit. Connect the PortaCoHydraulic Tester to the oppositeend of the hoses. Make sure flowdirection is correct.

c. Start the engine and allow thehydraulic fluid to warm to about100 F/38 C.

d. Open the tester restrictor valve(fully open.) This representsminimum load.

e. Set the flow control to “ON” andset engine throttle for maximumspeed.

f. Check the flow rate and pressureon the tester gauges. The backpressure reading should be under17.3 bar (250 PSI). The flowreadings should match thoselisted in section 1.1 GeneralInformation of this manual.

g. With engine throttle set atmaximum speed slowly close therestrictor valve on the tester whileobserving the flow pressuregauges.

h. As the hydraulic system reliefvalve begins to crack (open) andbypass fluid through the valve,the flow rate will begin to drop.At this time, the pressure in thesystem should be between 145-155 BAR (2100-2250 PSI).

i. If the pressure is not as specified,the hydraulic circuit relief valvemust be adjusted or replaced.(See section 4.2 for procedure.)

- If the flow rate drops below thespecified range, the pump orcontrol valve may be worn.

- If the flow remains constant, butpressure does not increase, therelief valve may be defective.

2.5 Adjustments

The engine RPM’s and the hydraulicsystem flow and pressure relief areset at the factory and must not bereadjusted. DO NOT changegovernor setting or tamper withgovernor components, which mayincrease the governed engine speed.

WARNING: OPERATING THEPOWER UNIT AT EXCESSIVESPEEDS INCREASE THE DANGEROF PERSONAL INJURY.

2.6 Hose Requirements

The Prowler series are easily movedclose to the job site. It is not oftennecessary or advisable to use longhoses. All hoses must have an oilresistant inner surface and anabrasion resistant outer surface.Each hose must have male pipeends for most application. Longerhoses can be used when necessary,but can affect the operation of theengine due to resistance in the hose.

If small diameter or long hoses areused, or if restrictive fittings areconnected to the supply and returnports, the pressure required, to pushthe fluid through the system andback to the tank will be higher. Thiswill reduce tool power.

The pressure and return hose areconnected to the control block. A ½-inch male pipe hose end can beconnected, to H.T.M.A. flat-nosedquick-disconnect couplings

(available through your PortaCo, Inc.dealer) can be used. (see fig. 2.6A)

The upper port of the control block isthe pressure (oil out) fitting. A maleH.T.M.A. quick-disconnect coupling(without lock ring) must beconnected to the tool end of thehose, which is connected to this port.

*Important – Oil should alwaysflow from the male couplerthrough the female coupler.

The lower port is the return port. Afemale H.T.M.A. quick-disconnectcoupling should be connected to thisport.

NOTE: The pressure increase inuncoupled hoses left in the sun maymake them difficult to connect.When possible after use, connect thefree ends of the operating hosestogether.

HOSE TYPES

Hydraulic hose types authorized foruse by PortaCo, Inc. is as follows:

1. Labeled and certified non-conductive2. Wire braided (conductive)3. Fabric braided (not certified or labeled

non-conductive)

Hose 1: Listed above is the only hoseauthorized for use near electricalconductors.

Hoses 2 and 3: Listed above are conductiveand must never be used near electricalconductors.

HOSE PRESSURE RATING

10

The rated working pressure of thehydraulic hose must be at least 175bar (2500 PSI.)

2.7 Tool Connecting Procedures.

Inspect hose for cuts, crushing, leaks, orabrasion which maybe a safety hazard orreduce fluid flows.

WARNING: DO NOTATTEMPT TO LOCATEHYDRAULIC LEAKS BY FEELINGAROUND HOSES AND FITTINGWITH HANDS.“PIN-HOLE” LEAKSCAN PENETRATE THE SKIN.

Stop the engine before connectingthe tool and, or hoses to the offpower unit, and when switchinghoses or tools. Turn the hydraulicon/off valve to the off position beforestarting the engine. Make sure allhose are connected for correct flowdirection to and from the tool beingused. When routing hose in thework area, position them wherepersonnel will not be at risk oftripping over them where vehiclescan run over the hoses. Do not layhose over sharp projects.

3.0 OPERATING INSTRUCTIONS

3.1 Description of Power Unit

The PortaCo Prowler seriesHydraulic Power Unit has beendesigned for the purpose ofsupplying hydraulic fluid underpressure to power hydraulic handtools. PortaCo power units producea maximum pressure of 148 BAR(2150 PSI) and a maximum flow rateof 40 LPM (10 GPM) at 3500 RPMS.A petrol (gasoline) engine featuringand electric starter powers thePortaCo Prowler series power unit.The standard engine is a Briggs andStratton 16 hp V-twin Vanguard or18 hp V-twin Vanguard dependingon the model of power unitpurchased. See section 1.2 featuresof this manual for specifications. Seethe technical manuals supplied bythe engine manufacture includedwith this power unit for detailedtechnical specifications.

PortaCo Hydraulic Power Units havebeen designed for use indoors andoutdoors. Portaco power unitsshould not be operated under wetconditions, or at ambient operatingtemperatures, outside therecommended temperature range of-28 C to 43 C. (-20 F to 110 F).

The prowler series power unitsprovide the required flow andpressure to operate HTMA type 1,type 2, and type RR tools. OnlyOPEN-CENTER tools requiring 20,30, 40 LPM (5, 8, 10 GPM) and amaximum operating pressure of 138BAR (2,000 PSI) are to be used withthe Prowler series power units. See

section 1.1 General Information fordetail specifications on individualsmodels.

CAUTION: DO NOT USE CLOSED-CENTER TOOLS WITH THISPOWER UNIT.

During operation, the engine maybog, run at lower rpm, when underload. As the tool being used isloaded, meets with increaseresistance, the pressure required tooperate the tool increases. Theincreased pressure adds load to thepump which loads the engine thereby reducing the RPMS. As a result,the flow will drop as pressureincreases. The hydraulic system hasa pressure limiter set at 148 BAR(2150 PSI) which diverts the flowback to tank until the pressure dropsbelow 148 BAR (2150 PSI.)

Tools with higher flow and, orpressure requirements will notoperate at their full potential if usedwith the PortaCo Hydraulic PowerUnit. Tool with lower flow and, orpressure requirements may bedamaged if used with this power unit.

The engine throttle and the hydraulicsystem relief value are preset at thefactory and must not be altered forany reason without consultingPortaCo Inc. Any alterationsapproved by PortaCo Inc., can onlybe preformed by personnel qualifiedto maintain hydraulic systems.

For model G-18S10-58-W turn thecontrol valve counter clockwise tothe “OFF” position. (fig. 3.5B)

For model G-18D55-53-E turn allcontrol levers to the “OFF” position.(fig. 3.5C)

(Fig. 3.5B)

(Fig. 3.5C)

When connecting hoses to the powerunit be sure the tool is to the properport for tool rating. The outside malecoupler are rated at 20 LPM(5 GPM)each and the center port is rated at40 LPM (10 GPM) as labeled on thedecal see Fig. 3.2N. To operate thepower unit at 40 LPM (10 GPM),both 20 LPM (5 GPM) valve controlsmust be in the "OFF" position. Thepressure hose must be connected tothe center port 40 LPM (10 GPM),and the return hose can beconnected to either of the two returnports.(D) To start engine pull throttle knob

(arrow K fig 3.2J) out slightly, nomore than ¼ of travel. Pull thechoke knob (arrow J fig. 3.2J) out

and turn ignition key. (arrow H fig3.2J) until engine starts. Useshort starting cycles (15 secs. permin.) to prolong starter life.Extended cranking can damagestarter motor.

(E) Adjust choke as required to keepengine running for 3 to 5 minutesbefore pulling throttle to fullRpm’s

(F) Rotate the hydraulic control valveto the “ON” position or on somemodels select the flow required.

*Important – Make sure the controlvalue is in the full counter-clockwise position beforeconnecting or disconnectinghoses to the tool.

Tools used with the Prowlerpower unit must be designed foroperation with open-centersystems.

3.6 Shutdown

A. NORMAL SHUTDOWN

1) Observe all safety precautions2) Rotate hydraulic control valves

tot he “OFF” position.3) While holding red button on

throttle knob in press throttleknob until engine idles.

4) Allow engine to idle for 2 to 3minutes; then turn ignition “OFF”,rotate counter clockwise.

2) Disconnect the hoses from thepower unit pressure hose first.

Then disconnect hoses from thetool. When possible after use,connect the free ends of theoperating hoses together. Thepressure increase in uncoupledhoses left in the sun may make

them difficult to connect.3) Allow the hydraulic power unit to

cool down before enclosing in asmall area for transportation orstorage.

B. EMERGENCY SHUTDOWN

In the event of an emergency, suchas fire, immediately set the ignitionswitch to “OFF”. (Fig. 3.2J Arrow H)

3.7. Cold Weather Operation

Hydraulic fluids are thicker in coldweather; therefore, run the engine atlow idle long enough to bring thefluid temperature up to minimum of10°C/50 F or until the hydraulic tankfeels warm.

In cold weather, a cover over thecooler will allow faster warm-up.

3.8 Storage Preparation

To prepare the engine fortransportation or storage refer to theengine owner's manual. Remove theground cable from the battery.

To prepare the hydraulic system forstorage fill the hydraulic oil reservoirto the full mark, and check that thefill cap and filter are tight. Whenremoving from storage during a 3month or longer period, drain thewater from the hydraulic oil reservoir,if any condensation has occurred,and replace the hydraulic oil filter.(See section 4) This will remove anywater which, may have condensed inthe hydraulic oil reservoir duringstorage.

20

Store the PortaCo Prowler hydraulicpower unit on a smooth levelsurface. The power unit should bestored in a cool, dry environment

which is not subjected to rapidtemperature changes.

4.3 HYDRAULIC FLUID ANDENGINE MAINTENANCE

WARNING: SHUT OFF ENGINEBEFORE DOING ANYMAINTENANCE. TO PREVENTACCIDENTAL START-UP, TURNTHE IGNITION SWITCH OFF ANDDISCONNECT THE NEGATIVECABLE FROM THE BATTERYTERMINAL.

Engine Lubrication ServicingCheck the engine oil level andchange oil and filter as required inthe maintenance table section 4.1 ofthis manual.

The oil level should be between the“full” and “add” marks of the dipstick(Arrow A, Fig. 2.2A). Also illustratedin the engine manual. To add oil tothe engine remove the filler cap(Arrow B, Fig. 2.2A). Engine oilcapacity is 1.6 liters (1 ½ quarts)when changing oil filter.

The following oils are recommendedby the engine manufacturer:

Temperature Range Oil5° C (40° F) and above SAE 30¯18° C- (0° F) - 5° C (40° F) 5W-30

10W-305° C (40° F) and below Synthetic 5W-20

5W-30

When draining oil place a suitablecontainer under the drain plug(Arrow A, Fig. 4.3A) and removeplug. Drain engine completely andreplace plug.

When replacing engine oil filter(Arrow B, Fig. 4.3A) place a suitablecontainer under the filter and removefilter. Apply a film of clean oil to the

gasket surface of the new filter.Install new filter element and tightenone-half turn after initial gasketcontact.

Engine Fuel Servicing

Replace the fuel filter every 300 hrs.or yearly (Arrow C, Fig. 2.2A). Movethe clamps up t he hoses, pull hosesoff filter cartilage. Press hoses ontonew filter cartilage and repositionclamps over barbed end of filter.The arrow on the fuel filter mustpoint towards the fuel pump. (ArrowE, Fig. 2.2A)

NOTE: See engine manual foradditional service requirements.

NOTE: Dispose of all consumableitems (filters, oils….etc.) in a mannerthat is compatible with theenvironment. PortaCo, Inc. suggestsyou take such items in a sealedcontainer to your local service stationfor reclamation. DO NOT throwthese items in the trash or pour themon the ground.

Hydraulic Fluid Servicing

Removing CondensationOnce a week (Less often in hot dryweather) take a small sample fromthe bottom of the hydraulic tank byremoving the ½” N.P.T. drain plug(Fig 4.3B). If clear water appears,drain the tank until clean oil starts toshow. Always drain tank into asuitable container. If fluid is milky,allow unit to settle for 48 hoursbefore draining.

NOTE: Water in the fluid reduceslubrication and causes prematurewear. 1% water in a 140 BAR (2000PSI) system can cause a 2.5%increases in wear rate.

(Fig. 4.3B)

Replace Filter and Fluid

CAUTION: ALWAYS FOLLOWANY HANDLING PRECAUTIONSPUBLISHED BY THEMANUFACTURES OF THELUBRICANTS OR HYDRAULICFLUIDS USED.

- Remove the drain plug on theunderside of the hydraulic tank(Fig. 4.3B) and drain oil into asuitable container. Let reservoir

completely drain and reinstall theplug.

- Place the drain pan under thehydraulic oil filter and removefilter. (Fig. 4.3C)

- Apply a film of clean oil to thegasket surface of a new hydraulicoil filter. PortaCo Inc. number1083-OOP (LHA# SPE-15-10).

- Install new filter element andtighten one-half turn after initialgasket contact.

- Fill hydraulic oil reservoir with afluid recommended in section 3.2of this manual. Fill tank until oillevel is just below filler tube.Reservoir capacity is 18.9 leters(5.0 gal.)

- Dispose of oil and filters in aresponsible manor, see previousnote.

CAUTION: ALWAYS FOLLOW ANYHANDLING PRECAUTI0NSPUBLISHED BY THEMANUFACTURES OF THELUBRICANTS OR HYDRAULICFLUIDS USED.

(Fig. 4.3C)

- Start engine and allow to run atidle for 3 minutes

- Shut engine off, check oil leveland add fluid if required. Do not
