WARNING: PLACING THEPORTACO HYDRAULIC POWERUNIT ON EXCESSIVE SLOPES ORUNSTABLE GROUND COULDCAUSE THE UNIT TO ROLL ORTIP DAMAGING THE POWER UNITOR ENDANGERING WORKERS.

Locate hydraulic power unit in well litarea with a minimum ambient lightintensity of 200 lux weather indoorsor outdoors, particularly at night.Keep the power unit at least 1 meter(3.3ft) away from buildings,obstructions, and flammable objects.

3.5 Start Up

(A) Observe all safety precautionsfound through out this manualand the included motor manual.

(B) Connect hydraulic hose to theapplicable coupler on the controlpanel. Male couplers arepressure ports. Female couplersare return ports.

NOTE: Clean ends of couplersbefore connecting to prevent systemcontamination.

(C) Turn the control value fullycounterclockwise (OFF). (Seefig. 3.5A)

(D)

(Fig. 3.5A)

(E) Turn motor switch ON or plugunit into power source. Allow themotor to run without activatingthe tool, until hydraulic circuitsare warm.

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

Tools used with the electric powerunit must be designed foroperation with open-centersystems.

Tool Operationa. Start the motor as specified in

paragraph 2.b. Turn the hydraulic circuit to

the ON position or a flowsetting to start fluid flowing tothe tool.

3.6 Shutdown

A. NORMAL SHUTDOWN

1) Observe all safety precautions2) Rotate hydraulic control valves to

the “OFF” position.3) Shut motor off.4) Disconnect the hoses from thepower unit pressure hose first. Thendisconnect hoses from the tool.When possible after use, connect thefree ends of the operating hosestogether. The pressure increase inuncoupled hoses left in the sun maymake them difficult to connect.3) Allow the hydraulic power unit tocool down before enclosing in asmall area for transportation orstorage.

*Important- Do not store hoses indirect sunlight or any hot location.Expansion of fluids can causepressure build up.

When storing hoses the couplersat the hose ends should beconnected together to preventcontamination from entering thehydraulic system.

B. EMERGENCY SHUTDOWN

In the event of an emergency,immediately turn the motor off.

Cold Weather Operation

Hydraulic fluids are thicker in coldweather; therefore, run the motorwith the flow valve off long enough tobring the fluid temperature up tominimum of 10°C/50 F or until thehydraulic tank feels warm.

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

3.8 Storage Preparation

To prepare the hydraulic system forstorage fill the hydraulic oil reservoirto the full mark, and check that thefill cap and filter are tight.

When removing from storage duringa 3 month 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.

Store the PortaCo electric hydraulicpower unit on a smooth levelsurface. The power unit should bestored in a cool, dry environmentwhich is not subjected to rapidtemperature change

4.3 MOTOR AND HYDRAULICFLUID MAINTENANCE

WARNING: SHUT OFF MOTORBEFORE DOING ANYMAINTENANCE. TO PREVENTACCIDENTAL UNPLUG POWERSOURCE.

Motor Maintenance

*Important- Remove all powerservices and allow machine toreach stand still prior to servicing.

On single phase motor dischargestart and/ or run capacitors priorto servicing.

a. Lubrication this is a ballbearing motor. The bearingshave been given initiallubrication at the factory.Motors without regreasingcapability are factorylubricated for normal bearinglife.

b. Relubrication Intervals(Motors having regreasingcapability). New motorshaving been in storage forover a year should berelubricated by the procedurenoted below. The followingrelubrication intervals aresuggested as a guide for longoperating life.

c. Lubricant Baldor motors arepregreased normally withShell Oil Company’s “DoliumR”. Several equivalentgreases with the Baldorfurnished greases are

Chevron Oil’s “SRI No. 2.”,Exxon Mobil Polyrex, TexacoPolystar, Rykon Premium #2,and Pennzoil Pen 2 Lube

d. Procedure over-greasingbearings can causepremature bearing failure. Ifmotor is equipped withAlemite fittings, clean tip offitting, and apply grease gun.

Use 1 or 2 full strokes onmotors in NEMA 215 frameand smaller. Use 2 to 3strokes on NEMA 365 frame.Use 3 to 4 strokes on NEMA404 frames and larger. Onmotors having drain plugsoperate motor for 20 minutesbefore replacing drain plug.

On motors equipped withslotted head grease screw,remove screw, and applygrease tube to hole. Insert 2to 3 inch length of greasestring into each hole onmotors in NEMA 215 frameand smaller. Insert 3 to 5 inchlength on larger motors.Motors having grease drainplugs remove plugs andoperate motor for 20 minutesbefore placing drain plug.

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. Ifclear water appears, drain the tankuntil clean oil starts to show. Always

drain tank into a suitable container.If fluid is milky, allow unit to settle for48 hours before 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.

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. 4.3A Arrow A) and drain oilinto a suitable container. Letreservoir completely drain andreinstall the plug.

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

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