Troubleshooting tips
Symptom Possible Cause Corrective Action
Pump will not start • No power or wrong voltage • Make sure that the unit is plugged in.
• Make sure that the power voltage
is correct.
• Check for loose wires on the circuit board.
• Check for loose wires on the CRIMP
switch.
Motor stalls under load • Low voltage • Verify that the branch circuit conforms
to the electrical specifications on Page 4
of this manual.
• Remove any extension cords.
Electric valve will not operate • No power or wrong voltage • Check for loose wires on the circuit board.
• Low voltage • Check for loose wires on the CRIMP
switch.
• Make sure that the power voltage
is correct.
Pump fails to build pressure • External leak in system • Wipe away spilled oil, and locate the
• Internal leak in pump source of leak. If the hose assembly is
• Internal leak in valve leaking, tighten or replace it. If the
• Internal leak in system component pump or cylinder is leaking, refer to the
ENERPAC Repair Parts Sheets. Slight
oil seepage of the cylinder is normal.

and repair or replace them if necessary.
• Lubricate the die cage per the maintenance
procedures on Page 9.
• Lubricate the tie rod bushings per the
maintenance procedures on Page 9..
Crimp diameters change • Incorrect hose/fitting combination • Verify the correct hose/fitting combination.
• Incorrect die cage • Verify the correct die cage.
• Die cage or crimp insert damage • Repair or replace the damaged
components.
• Transducer is loose • Tighten the transducer and brackets, and
• Loose crimp machine components then reclaimable them if necessary.
• External damage to crimp machine • Tighten any loose bolts or screws
• Insufficient lubrication on dies • Lubricate the die cage per the maintenance
procedures on Page 9.
• Lubricate the tie rod bushings per the
maintenance procedures on Page 9.
DISPLAY blinks • Loose or broken wires • Tighten any wires that may have become
loose on the circuit board, pump electrical
enclosure, or CRIMP switch.
If the symptom appears to be solely pump or cylinder related, refer to the ENERPAC Repair Parts Sheets.
Any electrical checks must be done by a qualified electrician.
Refill oil reservoir with ENERPAC premium hydraulic oil only (ENERPAC P/N H-F-101).
Remember: The electric motor only runs during the crimping process. The motor energizes
when the crimp/retract switch or footswitch is pressed and de-energizes when the cylinder
has retracted.
