Die Cage Maintenance Procedures

1. L
 ubricate the die cage. For maximum service, ET4020
die cages require lubrication at 50-crimp intervals with
NEVER•SEEZ (Weatherhead Part Number FT1092).
FT1092 is an eight ounce container that will provide
sufficient lubricant for about 5,000 crimps.
Periodically remove NEVER•SEEZ residue that has built
up on the sides of the dies and in the crimp ring during
the crimping process. NEVER•SEEZ residue becomes
contaminated with metal and plating chips and airborne
contaminants, which can cause premature wear of the
dies and crimp ring. It should carefully be removed without
mixing it with newly applied NEVER•SEEZ.

2. D
 ie cage maintenance should be performed at 1000-
crimp intervals or every six months, which ever occurs
first. Die cages should be free of grease and debris and
inspected for worn or damaged components.

other springs.
c. T

d. Inspect remaining components, and replace those
that are badly worn.
Reassemble components, and liberally apply NEVER•SEEZ
to the die surface which slides along the spring plate.
Torque the die cage bolts to 50 in. -lbs.
Ensure that all dies slide in and out freely.

Troubleshooting Tips

Remember: The electric motor only runs during the crimping process. The motor energizes when the crimp switch is
pressed and de-energizes when the crimp switch is released or when the crimp cycle is completed. While retracting, the
hydraulic dump valve is energized. When the valve is energized, oil flow is directed from the pump to the cylinder. When
the valve is de-energized, oil flows from they cylinder back to the reservoir.

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 source is on.
• 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 schematics on Page 13 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 source of
• Internal leak in pump leak. If the hose assembly is leaking, tighten or
• Internal leak in valve replace it. If the pump or cylinder is leaking,

• Tie rods may be binding • Replace the tie rods.
• Die cage may be binding • Check the die cage and crimp ring for damage,
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 then
• Loose crimp machine components recalibrate 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 performed by a qualified electrician.
