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.
ENERPAC CANNOT BE RESPONSIBLE FOR DAMAGE OR INJURY RESULTING FROM UNSAFE
USE OF PRODUCT, LACK OF MAINTENANCE, OR INCORRECT PRODUCT AND SYSTEM
APPLICATION. Contact Enerpac when in doubt as to applications and safety precautions.
WARNING
To avoid personal injury, always wear proper personal protective gear
when operating hydraulic equipment.
WARNING
The system operating pressure must not exceed the pressure
rating of the lowest rated component in the system.
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.
CAUTION
Carry the pump by the handle or the strap. Carrying or dragging
the pump by the hose can damage the hose and/or the pump.

INSTALLATION
Battery Pack
Slide the BP1724 battery pack into the battery compartment until it latches into place.
Illustration 1 on page 4 shows the proper installation of the battery pack.
CAUTION
The battery can be inserted only in the proper direction. Do not force
the battery into the compartment.
To remove the battery pack, press battery inward while pushing down on the battery
release latch (A). The battery will eject far enough to grasp and pull out.
IMPORTANT: Remove the battery from the pump when the pump is not in
use. Storing the battery in the pump will cause the battery to discharge rapidly.
To protect the life of the battery, store the battery pack in the charger.

Hydraulic Connections
Connect a hose from the pump to the tool.
Hand tighten couplers (C) fully to ensure that all connections are tight and leak free.
Oil Level
Place pump on level surface. Unscrew the vent/fill cap (D) to expose the reservoir fill
port. Add only Enerpac hydraulic oil. The reservoir is full when the oil level reaches
the lip (E) in the neck of the fill port.
IMPORTANT: Add oil only when the tool is fully retracted, or the system will contain
more oil than the reservoir can hold, causing oil to leak from vent/fillcap.

OPERATION
Oil Level
Check the oil before operating the pump. If oil level is low, add oil until oil level
reaches the lip in the neck of the fill port.
Venting
Venting is provided automatically through the vent/fill cap, which also protects against
reservoir over-pressurization.
Indicator Light
Illustration 4 shows the position of the indicator light (F). The light informs the operator
when the battery is depleted and when the motor has failed to operate.
When the battery needs recharging, the indicator light flashes, and will continue to flash
until the battery has been removed.
If the motor does not operate, the indicator fault light will go on and remain on as long
as the pressure pushbutton remains pressed. See the Troubleshooting table on page 7 if
the motor fails to operate.
With Manual Release Valve (See Illustration 5)
1. Close the release valve by turning the knob
clockwise.
2. To advance the tool, activate the pump motor
by pressing the pushbutton.
3. Releasing the button stops the motor.
4. To release system pressure, slowly turn the
release valve counterclockwise.
With Dump Valve
1. To advance the tool, activate the motor by pressing the pushbutton.
2. Releasing the pushbutton stops the pump and releases system pressure, retracting the
tool.

With Dump and Hold Valve (See Illustration 6)
1. To advance the tool, press the "PRESSURE" pushbutton.
2. Release the pushbutton and the pump will hold pressure.
3. To release system pressure and retract the tool, press the "RELEASE" pushbutton.
With Pendant
Illustration 7 shows the operating positions of the pendant
pushbuttons. The pendant duplicates the operation of the
pushbutton(s) located on the pump control panel.
With Dump Valve
Pressing the pendant pushbutton will activate the motor and advance
the tool. Releasing the pendant pushbutton will retract the tool.
With Dump and Hold Valve
Pressing the pendant PRESSURE pushbutton (1) activates the motor
and advances the tool. Release the PRESSURE pushbutton, and the
pump will hold pressure. Pressing the the pendant RELEASE
pushbutton (2) releases system pressure and retracts the tool.
MAINTENANCE
Battery Charging
Charge the battery by plugging in the charger and sliding the battery into the battery
holder. The yellow light flashes to indicate that the battery is charging. When the green
light goes on, the battery is fully charged. For complete information, see charger and
battery pack instruction sheet L1863.
Battery Care
Store the battery in the battery charger to maintain the battery in the fully charged
condition. Shelf storage will result in slow discharge of the battery. Store the battery
and charger in a cool dry environment. For complete information, see the charger and
battery instruction sheet L1863.
Changing the Oil
Change the oil in the pump once a year.
1. Run the pump completely out of oil, letting oil drain into a container.
2. Unscrew and remove the vent/fill cap.
3. Add new Enerpac hydraulic oil until oil level reaches the lip in the neck of the fill port.
4. Dispose of used oil properly.

BATTERY
RECYCLING The battery contains hazardous material. Dispose of the battery pack in accordance with
local regulations. For more information on recycling, see the battery recycling sheet,
L1873, which came with your battery pack.
TROUBLESHOOTING
The following information is intended as an aid in determining if a problem exists.
DO NOT disassemble the pump. For repair service, contact the Authorized Enerpac
Service Center in your area.
Problem Possible Cause Solution
Tool does not advance,
advances slowly, or
advances in spurts.
Oil level in pump reservoir
is low.
Add oil according to the instructions on page 4.
Release valve open. Close the release valve.
Loose hydraulic coupler. Check that all couplers are fully tightened.
Load is too heavy. Do not attempt to lift more than rated tonnage.
Air trapped in system. Remove air by holding the pump higher than the tool and cycling
it several times without building pressure.
Cylinder plunger binding. Check for damage to cylinder.
Have cylinder serviced by a qualified hydraulic technician.
Tool advances, but
does not hold pressure.
Leaking connection. Check that all connections are tight and leak free.
Leaking seals. Locate leak(s) and have equipment serviced by
a qualified hydraulic technician.
Internal leakage in pump. Have pump serviced by a qualified hydraulic technician.
Tool does not retract,
retracts part way, or
retracts more slowly
than normal.
Release valve closed. Open release valve.
Pump reservoir is
over-filled.
Drain oil level to lip in reservoir neck.
See page 4 for filling instructions.
Loose hydraulic coupler. Check that all couplers are fully tightened.
Air trapped in system. Remove air by holding the pump higher than the tool and cycling
it several times without building pressure.
Hose I.D. too narrow. Use a hydraulic hose with a larger diameter.
Cylinder retraction spring
broken or other cylinder
damage.
Have cylinder serviced by a qualified hydraulic technician.
Motor fails to operate
Red light "ON"
Internal thermal switch is
open
Wait approximately 20 minutes for the motor to cool.
Break in the wiring Have the pump serviced by a qualified hydraulic technician
Failure of the motor relay Have the pump serviced by a qualified hydraulic technician
