POWER SUPPLY
Electric
Electrical Shock or Electrocution
• Any electrical work must be done and tested by a qualified electrician per local directives and
standards.
• 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 procedure.
Consult the manufacturer for specific 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. PE8 Series, PE17 Series, PE30 Series, PR10 Series, and PE46 Series pump motors
must be wired for counterclockwise (CCW) rotation when viewed from the lead end (top) of the motor.
• 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 fire will result.
• To rewire a motor from one voltage to another or when a flow 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 hazard.
• Avoid conditions which can cause damage to the power cord such as abrasion, crushing, sharp cutting

SAFETY PRECAUTIONS (POWER SUPPLY) CONTINUED -
Air Driven Motor
• A quick disconnect must be installed in the air line to the pump.
• Disconnect air supply and relieve pressure when pump is not in use or when breaking any
connection in the hydraulic system.
• Control circuit must comply with local directives and standards.
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 Instructions” 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 fittings. 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 fittings 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 fluid could cause serious injury.
•Do not subject the hose to potential hazard such as fire, 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 fluid flow 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 fluid 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 internal
high pressure relief valve. Creating pressure beyond rated capacities can result in personal injury.
•Before replenishing the fluid level, retract the system to prevent overfilling the pump reservoir or bladder.
An overfill can cause personal injury due to excess reservoir or bladder 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.
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 cylinder, hose or coupler
can burst, possibly causing serious injury or death.
HYDRAULIC FLUIDS
•Properly dispose of all fluids, components, and assemblies at the end of their useful life.
•Hydraulic fluid should be compatible with all hydraulic components.

Operating Instructions Form No. 102875
SET-UP INSTRUCTIONS
Filling The Pump Reservoir Or Bladder
NOTE: Most pumps are shipped without hydraulic fluid in the reservoir. Hydraulic fluid may have been
shipped with the pump in a separate container. If hydraulic fluid is needed, use 215 SSU @ 100° F (47 cSt @
38° C) hydraulic fluid. Pumps with a bladder are shipped with hydraulic fluid in the bladder.
1. Clean the area around the filler cap to remove all dust and grit. Any dirt or dust in the hydraulic fluid can damage
the polished surfaces and precision-fit components of this pump.
2. Retract all cylinder(s) to their return position.
3. Remove the filler cap and insert a clean funnel with a filter. Fill the reservoir with hydraulic fluid to 1" (25,4 mm)
(PE8, PE17 & PE30 series pumps to 1-1/2" [38,1 mm]) from the cover plate. PR10 series pump bladder must be
filled completely. Replace the filler cap. IMPORTANT: For PR10 series pumps, tighten filler cap 1/2 - 1 turn
after o-ring contacts sealing surface. Overtightening can cause pump damage on bladder equipped
pumps.
Hydraulic Connections
Remove the thread protectors or dust covers from the hydraulic ports if applicable. Clean the areas around the fluid
ports of the pump and cylinder. Inspect all threads and fittings 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 fittings can act as restrictors as the cylinder or ram retracts. The restricting or slowing of the fluid
flow 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 fitting, length of the hose, and the temperature
and viscosity of the hydraulic fluid.
HOSES TUBING
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 system
several times. Check the reservoir for possible low fluid level and fill to proper level with approved, compatible
hydraulic fluid as necessary (see “Filling The Pump Reservoir Or Bladder” section under Set-up Instructions).

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 fluid 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.

Single-acting, Spring Return Cylinder: Either fluid 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", fluid port "A" becomes
pressurized. When solenoid is energized to position "B", fluid
port "A" becomes the return port.
Double-acting Cylinders: When operating double-acting
cylinders, fluid port "A" can be connected to either the advance
or return port of the cylinder and fluid 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 extends the cylinder and fluid 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 cylinders (one double-
acting cylinder may be used). Interflow will occur.
If a different set-up or cylinder is being considered, contact your

ADJUSTING THE PRESSURE REGULATING CONTROLS CONTINUED -
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.
1. 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.
2. The pump must be completely connected electrically and hydraulically. Start the pump.
3. 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 during
adjustment.
Figure 6
Figure 7
NOTE: When the pressure switch setting is reached, the motor will shut off. However, the inertia of the motor
continues to deliver fluid for a brief period. The pressure regulating valve bypasses this surplus hydraulic
fluid, preventing it from going into the system. As a result, the pressure differential can be held to
approximately 300 PSI (21 BAR).

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 elsewhere in the
circuit. Refer to Figure 7.
1. Loosen the locknut (B) on the pressure switch, and turn adjusting screw
(A) in a clockwise (CW) direction. This
increases the pressure setting to a
higher than desired pressure.
2. Adjust the pressure regulating valve to the desired pressure setting. Refer
to the section titled “Adjusting The Pressure Regulating Valve”.
3. With the pump running and bypassing fluid 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).
4. Release pressure. Run the pump to check the pressure setting and cut-
out of the motor. If may be necessary to make a second adjustment.

Checking The Hydraulic Fluid And Filling The Bladder
The hydraulic fluid level should be checked after initial set-up and after each ten hours of use.
1. Thoroughly clean the area around the filler cap with a clean cloth to prevent contamination of the hydraulic fluid.
2. Cylinder(s) must be fully retracted and the power supply disconnected. Position the pump with the filler plug in the
up (or vertical) position.
3. Remove the filler cap and insert a clean funnel with filter. Fill the bladder completely full with a high grade
hydraulic fluid.
4. Replace filler cap. IMPORTANT: Tighten filler cap 1/2 - 1 turn after o-ring contacts sealing surface.
Overtightening can cause pump damage on bladder equipped pumps.
5. The frequency of fluid changes will depend upon the general working conditions, severity of use, and overall
cleanliness and care given the pump. Three hundred hours of use under general shop conditions is considered a
standard change interval. Drain, clean, and refill the reservoir with a high grade hydraulic fluid.
Maintenance Cleaning
IMPORTANT: Never use a high pressure washer to clean hydraulic components!
1. Keep the pump's outer surface as free from dirt as possible.
2. Seal all unused couplers with thread protectors.
3. Keep all hose connections free of dirt and grime.
4. The breather-hole in the filler cap must be clean and unobstructed at all times.
5. Equipment connected to the pump must be kept clean.
6. Use a high grade hydraulic fluid in this pump. Change as recommended (every 300 hours). Some conditions may
require the use of different viscosity hydraulic fluids.
Lubrication (Air Driven Motor Only)
If the pump is operated on a continuous duty cycle or a maximum speeds for extended periods, an automatic air line
oiler should be installed in the air inlet line as close to the pumping unit as possible. Set the unit to feed 1-3 drops of
oil per minute (one drop for every 65 CFM [1,8 M3/min.] of air) into the system, or refer to the pump manufacturer's
instructions. Use SAE No. 10 oil.
Engine Oil (Gas Engine Only)
Change engine oil as recommended for four stroke engines.
Mix the correct oil into fuel in proper ratio as recommended for two stroke engines.
Reservoir Vent Air Filter (Optional for all pumps except PR10 series)
1. Remove the filler cap, and insert either the 45° fitting or the straight fitting. Fasten o-ring end of fitting into pump.
2. If the 45° fitting is used, place the rubber spacer (included) on the top threaded portion.
Then thread the air filter on and hand tighten.
3. If the straight fitting is used, thread the air filter on and hand tighten. Sheet No. 7 of 8
