Figure 6.0-1 Enerpac Ct-604 Pressure Relief Tool - PCC FTI PowerPak FT-B100 Series Operation, Maintenance, And Repair Manual

Symptom
Noisy and/or vibrating
pump operation.
Cylinder will not advance
or retract.
Cylinder advances and
retract erratically.
Pump builds full pressure
without puller attached
and will not release
pressure or allow puller
unit to be attached.
Solution Steps:
Once hydraulic pressure has been introduced to the hydraulic hose,
the pressure must be relieved before the coupler can be sufficiently tightened.
Procedure for relieving hydraulic pressure:
1. Remove Battery.
2. Disconnect coupler from PowerPak if connected.
3. Connect Enerpac CT-604 to the female coupler and
bleed off hydraulic oil to relieve the built-up pressure.
Figure 6.0-1 shows the Enerpac CT-604 Pressure Relief Tool.
4. Once pressure is relieved, coupler may be tightened and
reinstalled onto PowerPak.
5. Replace the battery.
6. Check oil level in PowerPak Reservoir.
