IMPORTANT RECEIVING INSTRUCTIONS
Visually inspect all components for shipping damage. If any
shipping damage is found, notify carrier at once. Shipping
damage is NOT covered by warranty. The carrier is
responsible for all repair or replacement cost resulting from
damage in shipment.
SAFETY INFORMATION
To avoid personal injury or property damage during system
operation, read and follow all CAUTIONS, WARNINGS, and
INSTRUCTIONS included with or attached to each product.
The manufacturer CANNOT BE RESPONSIBLE FOR
DAMAGE OR INJURY RESULTING FROM UNSAFE USE OF
PRODUCT, LACK OF MAINTENANCE, OR INCORRECT
PRODUCT AND SYSTEM APPLICATIONS. Contact the
manufacturer when in doubt as to safety precautions or
applications.
CAUTION: Always use the handle to carry the
pump. Carrying the pump by the hose may
damage the hose and or the pump.
WARNING: Make sure that all system components
are protected from external sources of damage,
such as excessive heat, flame, moving machine
parts, sharp edges, and corrosive chemicals.
WARNING: Always check product limitations
regarding pressure ratings, load capacities, and
set-up requirements. The system operating
pressure must not exceed the pressure rating of the
lowest rated component in the system.
WARNING: NEVER set the relief valve to a higher
pressure than the maximum rated pressure of the
pump. Higher settings may result in equipment
damage and/or personal injury. See chart above for the
maximum pressure rating.
DESCRIPTION
Figure 1 shows the main components of the pump. The dual-
purpose vent/fill camp acts as a pressure relief valve in case
of accidental reservoir pressurization. To provide an access
port at the rear of the reservoir for remote valves, use a
return-to-tank kit (model number PC-20).
INSTALLATION
Connecting the Pump
1. Thread hose into pump outlet. Use 1fi wraps of Teflon
tape (or suitable thread sealant) on the hose fitting,
leaving the first thread completely free of tape to ensure
that tape does not shed into hydraulic system, causing
damage.
2. Install a pressure gauge in-line from the pump for added
safety and better control.
3. Connect the hose to your cylinder or tool.
Pump Venting
This pump may be operated in a vented or unvented position.
(Vented pumps provide slightly better performance.) To vent,
turn the vent/vill cap counter-clockwise ⁄ turn. Close vent
prior to transporting pump to prevent leakage.
OPERATION
Before Using the Pump
1. Check all system fittings and connections to be sure they
are tight and leak free.
2. Check oil level in reservoir before operating pump. See
“Adding Oil to the Pump” on page 2.
Pumping / Using the Release Valve
1. Operate pump foot pedal to deliver hydraulic power to
system. Hydraulic pressure will be maintained until
release valve is open.

2. Open the release valve and release hydraulic pressure by
pressing the release valve down (see figure 1, item A).
Relief Valve Adjustment
All pumps contain a factory set relief valve to prevent over-
pressurization of the system. Lower pressure settings can be
ontained. Contact you authorized service center.
Air Removal
Removing air from the hydraulic system will help the cylinder
to advance and retract smoothly.
1. Vent pump reservoir.
2. Position the pump at a higher elevation than the cylinder.
3. Position the cylinder with the plunger-end down (see
figure 2). If using a pull cylinder, position the cylinder with
the plunger-end up.
4. Operate the pump to fully extend the cylinder. If using a
pull cylinder, operate the pump to fully retract the cylinder.
5. Open the release valve to retract the cylinder (extend the
cylinder if using a pull cylinder). This will force trapped air
to move up to the pump reservoir.
6. Repeat steps 1-5 untill the cylinder moves smoothly.
7. Add oil if necessary.
MAINTENANCE
Check oil level regularly.
Use only Enerpac hydraulic oil with these pumps to promote
long pump life and protect your warranty. Viton and EPR seal
kits are available for some hand pumps. Contact your
Enerpac representative for more information on these
products and their applications.
Adding Oil to the Pump
WARNING: Always add oil with the cylinders
fully retracted or the system will contain more
oil than the reservoir can hold. (With pull
cylinders, the cylinders should be fullly extended.)
1. Remove the vent/fill cap from the reservoir.
2. Fill reservoir only to level mark shown on pump.
3. Remove air from system if necessary. See "Air Removal".
Recheck oil level after removing air from the system.
4. Return the vent/fill cap to the reservoir.
Note: If you are not venting the pump, some air must be
left in the reservoir for the pump to function properly. If
the reservoir is completely filled, a vacuum will form,
preventing oil from flowing out of the pump.
Keeping Oil Lines Clean
When coupler halves are disconnected, always screw on dust
caps. Dirt or foreign matter may cause damage to pump,
cylinder, or valve.
Changing the Oil
The reservoir should be drained and refilled with Enerpac oil
at least once every 12 months. If the pump is used in dirty
environments, the oil should be changed more often.
1. Remove the vent/fill cap from the reservoir.
2. Tilt pump to drain out old oil.
3. Fill reservoir with clean oil to the level mark.
4. Replace the vent/fill cap.
5. Dipose of used oil properly.

Problem Possible Cause Solution
Cylinder does not advance,
advances slowly, or advances in
spurts.
Oil level in pump reservoir is low. Add oil. See page 2.
Cylinder advances, but does not
hold pressure.
Leaking connection. Check that all connections are tight
and leak free.
Cylinder does not retract, retracts
part way, or retracts more slowly
than normal.
Release valve is closed. Open the release valve.
Release valve open.
Load is too heavy.
Cylinder plunger binding.
Loose hydraulic coupler.
Air trapped in system.
Leaking seals. Locate leaks and have equipment
serviced by a qualified hydraulic
technician.
Check for damge to the cylinder.
Have the cylinder serviced by a
qualified hydraulic technician.
Remove air. See page 2.
Do not lift more than recommended
load.
Check that couplers are fully
tightened.
Close release valve.
Internal leakage in pump. Have pump serviced by a qualified
hydraulic technician.
Pump reservoir is over-filled. Drain oil level to full mark.
Loose hydraulic coupler. Check that all couplers are fully
tightened.
Air trapped in system. Remove air according to
instructions on page 2.
Hose ID too narrow. Use larger diameter hydraulic hose.
Cylinder retraction spring broken or
other cylinder damage.
Have cylinder serviced by a qualified
hydraulic technician.
