WARNING
To help prevent personal injury,
GENERAL
• Always wear eye protection whenever operating hydraulic equipment.
• Always wear hearing protection as required. Refer to the sound level (dB[A]) chart.
• Operation, repair, or maintenance of hydraulic equipment should be performed by a quali-
edpersonwhounderstandstheproperfunctionofhydraulicequipmentperlocaldirec-
tives and standards.
• Hydraulic equipment must be assembled correctly and then checked for proper function
before use. Use hydraulic components of the same hydraulic pressure ratings. An appro-
priate hydraulic pressure gauge is recommended to monitor pressure.
• Neverplaceyourhandsorotherbodypartsnearahydraulicuidleak.Neveruseyour
handsorotherbodypartstocheckforapossibleleak.Highpressureuidcanbeinjected
under your skin causing serious injury and/or infection.
• Highpressureuidispresentthroughoutahydraulicsystem.Alwaysusecautionwhen
operating, repairing, or maintaining this equipment. Before beginning any work on any
hydraulic system component, stop the equipment, disconnect from its power source, and
relieve all pressure in all parts of the system. Do not tamper with the internal hydraulic
relief valve settings.
• Avoid exposing hydraulic equipment (especially hoses) to extreme high or low tempera-
tures. Damage to equipment or failure may result and cause loss of control or injury to the
operator.
• Exercisecautiontoavoidtheriskofre.
• Do not drop any hydraulic system components. Damage to the equipment and/or injury
may result.
• Avoid slipping or falling by cleaning up any oil spills.
• Avoid back injury by always lifting equipment carefully.
• It is strongly recommended to view the Power Team Hydraulic Safety video tape before

POWER SUPPLY
Electric
Electrical Shock or Electrocution
• Anyelectricalworkmustbedoneandtestedbyaqualiedelectricianperlocaldirectivesandstan-
dards.
• Disconnect the pump from the power supply and relieve pressure before removing the motor case
cover or performing maintenance or repair.
• Never use an ungrounded power supply with this unit.
• If the power cord is damaged or wiring is exposed, replace or repair immediately.
• Changing the voltage on this unit is an involved, and if improperly performed, hazardous proce-
dure.Consultthemanufacturerforspecicinformationbeforeattemptinganyrewiring.
• All PE55 Series pump motors must be wired for clockwise (CW) rotation when viewed from the lead
end (top) of the motor.

Rev. 0 December, 2014
• Check the total amperage draw for the electrical circuit you will be using. (For example: Do not plug
a pump or pumps that may draw 25 amps into a 20 amp fused electrical circuit.)
• Do not attempt to increase the powerline capacity by replacing a fuse with another fuse of higher
value.Overheatingofthepowerlineandthepossibilityofarewillresult.
• Torewireamotorfromonevoltagetoanotherorwhenaowcontrolvalveischangedbetween
manual and solenoid, consult the electrical schematic in the pump’s parts list.
• Electric pumps should never be exposed to rain or water which could cause personal electrical haz-
ard.
• Avoid conditions which can cause damage to the power cord such as abrasion, crushing, sharp
cutting edges, or corrosive environment. Damage to the power cord can cause an electrical hazard.
HYDRAULIC HOSES AND FLUID TRANSMISSION LINES
• Avoid straight line tubing connections in short runs. Straight line runs do not provide for expansion
and contraction due to pressure and/or temperature changes. See diagrams in “Set-up Instruc-
tions” section of this form.
• Eliminate stress in the tube lines. Long tubing runs should be supported by brackets or clips.
Tubesthroughbulkheadsmusthavebulkheadttings.Thismakeseasyremovalpossibleand
helps support the tubing.
• Before operating the pump, all hose connections must be tightened with the proper tools. Do not
overtighten. Connections should only be tightened securely and leak-free. Overtightening can
causeprematurethreadfailureorhighpressurettingstosplitatpressureslowerthantheirrated
capacities.
• Should a hydraulic hose ever rupture, burst, or need to be disconnected, immediately shut off the
pump and release all pressure. Never attempt to grasp a leaking pressurized hose with your hands.
Theforceofescapinghydraulicuidcouldcauseseriousinjury.
• Donotsubjectthehosetopotentialhazardsuchasre,sharpsurfaces,extremeheatorcold,or
heavyimpact.Donotallowthehosetokink,twist,curl,crush,cut,orbendsotightlythattheuid
owwithinthehoseisblockedorreduced.Periodicallyinspectthehoseforwear,becauseany
of these conditions can damage the hose and possibly result in personal injury. Never repair with
tape.
• Do not use the hose to move attached equipment. Stress can damage the hose and possibly cause
personal injury.
• Hosematerialandcouplersealsmustbecompatiblewiththehydraulicuidused.Hosesalsomust
not come in contact with corrosive materials such as creosote-impregnated objects and some
paints. Hose deterioration due to corrosive materials can result in personal injury. Consult the
manufacturer before painting a hose. Never paint a coupler.
PUMP
• Do not exceed the hydraulic pressure rating noted on the pump nameplate or tamper with the in-
ternal high pressure relief valve. Creating pressure beyond rated capacities can result in personal
injury.
• Beforereplenishingtheuidlevel,retractthesystemtopreventoverllingthepumpreservoir.An
overllcancausepersonalinjuryduetoexcessreservoirpressurecreatedwhenthecylindersare
retracted.
• Always shut off the motor or engine and relieve pressure before breaking any connections in the
system.
• The motor or engine is the major part of the weight of the pump. Always take this into consideration
when lifting or moving the pump.

Rev. 0 December, 2014
CYLINDER
• Do not exceed the rated capacities of the cylinders. Excess pressure can result in personal injury.
• Do not set poorly balanced or off-center loads on a cylinder. The load can tip and cause personal
injury.
• Read and understand the cylinder operating instructions and warning decals before
using the cylinder.
DANGER
A double-acting cylinder or ram must have both hoses and all couplers securely connected to both
ports. If one of the two ports is restricted or becomes disconnected, pressure will build and the cylin-
der, hose or coupler can burst, possibly causing serious injury or death.
HYDRAULIC FLUIDS
• Properlydisposeofalluids,components,andassembliesattheendoftheirusefullife.
• Hydraulicuidshouldbecompatiblewithallhydrauliccomponents.

SET-UP INSTRUCTIONS
1. Filling The Pump Reservoir.
NOTE
Mostpumpsareshippedwithouthydraulicuidinthereservoir.Hydraulicuidmayhavebeen
shippedwiththepumpinaseparatecontainer.Ifhydraulicuidisneeded,use215SSU@100°F
(47cSt@38°C)hydraulicuid.
A. Clean the area around the ller cap to remove all dust and grit. Any dirt or dust in the hydraulic uid can
damage the polished surfaces and precision-t components of this pump.
B. Retract all cylinder(s) to their return position.
C. Remove the ller cap and insert a clean funnel with a lter. Fill the reservoir with hydraulic uid to 1”
(25,4 mm) from the cover plate, replace the ller cap.
2. Hydraulic Connections
Remove the thread protectors or dust covers from the hydraulic ports if applicable. Clean the areas around the
uid ports of the pump and cylinder. Inspect all threads and ttings for signs of wear or damage, and replace as
needed. Clean all hose ends, couplers and union ends. Connect all hose assemblies to the pump and cylinder.
Use an approved, high-grade pipe thread sealant to seal all hydraulic connections. Tighten securely and leak-
free but do not overtighten.
Hydraulic lines and ttings can act as restrictors as the cylinder or ram retracts. The restricting or slowing of the
uid ow causes back pressure that slows the cylinder’s or ram’s return. Return speed also varies because of
the application, condition of the cylinder or ram, inside diameter of hose or tting, length of the hose, and the
temperature and viscosity of the hydraulic uid.

3. Bleeding The System
After all connections are made, the hydraulic system must be bled of any trapped air. Refer to the diagrams
below.
With no load on the system and the pump vented and positioned higher than the cylinder or ram, cycle the sys-
tem several times. Check the reservoir for possible low uid level and ll to proper level with approved, com-
patible hydraulic uid as necessary (see “Filling The Pump Reservoir” section under Set-up Instructions).

7. Solenoid Controlled, Pilot Operated Valve Used With Double-acting Cylinders
PT
AB
9512
OPERATION
Neutral (HOLD): When both solenoids are de-energized, uid from pump circulates at free ow from the pres-
sure port “P” to tank “T”. Both cylinder ports are blocked.
Solenoid “A” Energized: Pressure to cylinder port “A”. Cylinder port “B” to tank.
Solenoid “B” Energized: Pressure to cylinder port “B”. Cylinder port “A” to tank.
NOTE
Pressure holds without loss when shifted from cylinder port to the neutral (HOLD) position.
Single-acting, Spring Return Cylinder: Either uid port “A” or “B” must be plugged with a steel plug on the
valve. With port “B” plugged, the sequence of operation is as follows: When solenoid is energized to position
“A”, uid port “A” becomes pressurized. When solenoid is energized to position “B”, uid port “A” becomes the
return port.
Double-acting Cylinders: When operating double-acting cylinders, uid port “A” can be connected to either
the advance or return port of the cylinder and uid port “B” will be connected to the remaining port. Sequence
of operation is as follows: When solenoid is energized to position “A”, port “A” becomes pressurized and ex-
tends the cylinder and uid port “B” becomes the return port. When solenoid “B” is energized, the opposite of
step 1 happens.
The application in Figure 5 represents a typical set-up using a control valve and multiple double-acting cylin-
ders (one double-acting cylinder may be used). Interow will occur.
If a different set-up or cylinder is being considered, contact your nearest Power Team facility.

ADJUSTING THE PRESSURE REGULATING CONTROLS
The pressure regulating valve and pressure switch are shown in Figure 6. The pressure regulating valve can
be adjusted to bypass uid at a given pressure setting while the pump continues to run. The pressure switch
can be adjusted to stop the pump at a given pressure setting. To ensure accuracy and low pressure differential
(approx. 300 PSI [21 BAR]) throughout the pressure range (1,000 to 10,000 PSI [70 to 700 BAR] depending on
the pump model), the pressure switch should be used with the pressure regulating valve. The pressure switch
must be set at a pressure lower than the pressure regulating valve to work properly.
1. Adjusting The Pressure Regulating Valve
NOTE
For easy adjustment of the pressure regulating valve, always adjust the pressure by increasing to the
desired pressure setting.
A. Loosen the locknut (B) on the pressure regulating valve, and back the adjusting screw or knob (A) out
a few turns by turning it in a counterclockwise (CCW) direction. This will decrease the setting to a lower
than desired pressure.
B. The pump must be completely connected electrically and hydraulically. Start the pump.
C. Slowly turn the adjusting screw or knob (A) in a clockwise (CW) direction. This gradually increases the
pressure setting. When the desired pressure is reached, lock the adjusting screw (A) in position by
tightening the locknut (B). Shut off the pump.
IMPORTANT
• The pressure range is from 1,000 to 10,000 PSI (70 to 700 BAR) depending on the pump model.
• The pressure switch must be set at a higher pressure than working range to prevent shut down dur-
ing adjustment.

2. Adjusting The Pressure Switch
Generally, the pressure switch should be used with the pressure regulating valve. A pressure switch can be
used alone for operating electrical devices such as motors, solenoids, relays, etc., which are located else-
where in the circuit. Refer to Figure 7.

ing The Pressure Regulating Valve”.
C. With the pump running and bypassing uid at the desired pressure, slowly turn the pressure switch
adjusting screw (A) in a counterclockwise (CCW) direction, decreasing the pressure switch setting until
the pump motor shuts off. Then lock the adjusting screw (A) in position by tightening the locknut (B).
D. Release pressure. Run the pump to check the pressure setting and cut-out of the motor. It may be nec-
essary to make a second adjustment.
NOTE
When the pressure switch setting is reached, the motor will shut off. However, the inertia of the motor

PREVENTIVE MAINTENANCE
WARNING
To help prevent personal injury,
• Disconnect the pump from the power supply before performing maintenance or repair
procedures.
• Repairsandmaintenancearetobeperformedinadust-freeareabyaqualiedtechni-
cian.
1. Checking The Hydraulic Fluid and Filling The Reservoir
The hydraulic uid level should be checked after initial set-up and after each ten hours of use.
A. Thoroughly clean the area around the ller cap with a clean cloth to prevent contamination of the hy-
draulic uid.
B. Cylinder(s) must be fully retracted and the power supply disconnected.
C. Remove the ller cap and insert a clean funnel with lter. Fill to proper level as instructed in “Filling The
Pump Reservoir” under Set-up Instructions.
D. Replace ller cap.
E. The frequency of uid changes will depend upon the general working conditions, severity of use, and
over cleanliness and care given the pump. Three hundred hours of use under general shop conditions
is considered a standard change interval. Rain, clean, and rell the reservoir with a high grade hydrau-
lic uid.

2. Maintenance Cleaning
IMPORTANT
Never use a high pressure washer to clean hydraulic components!
A. Keep the pump’s outer surface as free from dirt as possible.
B. Seal all unused couplers with thread protectors.
C. Keep all hose connections free of dirt and grime.
D. The breather-hole in the ller cap must be clean and unobstructed at all times.
E. Equipment connected to the pump must be kept clean.
F. Use a high grade hydraulic uid in this pump. Change as recommended (every 300 hours). Some con-
ditions may require the use of different viscosity hydraulic uids.
3. Reservoir Vent Air Filter (Optional for all pumps)
A. Remove the ller cap, and insert either the 45° tting or the straight tting. Fasten O-ring end of tting
into pump.
B. If the 45° tting is used, place the rubber spacer (included) on the top threaded portion. Then thread
the air lter on and hand tighten.
C. If the straight tting is used, thread the air lter on and hand tighten.
4. Draining And Cleaning The Reservoir
IMPORTANT
Clean the pump exterior before the pump interior is removed from the reservoir.
A. Remove the screws fastening the motor and pump assembly to the reservoir.
IMPORTANT
Donotdamagethegasketorpumplterorpressureregulatingvalveswhenliftingthepumpandmo-
tor off the reservoir.
B. Clean the inside of the reservoir and clean the lter.
C. Place the pump and motor assembly back onto the reservoir, and secure with machine screws.
D. Fill the reservoir with a clean, high grade hydraulic uid (refer to “Filling The Pump Reservoir” under
Set-up Instructions for proper uid level for your pump).
