6. Shift the valve to the neutral position, allowing the
system pressure to return to 0 psi.
7. Recheck the final pressure setting by shifting the
valve and pressurizing the system.

6.0 MAINTENANCE
1. Periodically check all hydraulic connections to be
sure they are tight. Loose or leaking connections
may cause erratic and/or total loss of operation.
Replace or repair all defective parts promptly.
2. Periodically check the hydraulic oil level in your
system. Refer to the oil filling instructions for
complete data.
3. Change hydraulic oil approximately every 250-300
hours of operation. In dusty or dirty areas, it may
be necessary to change the oil more frequently.
7.0 HYDRAULIC SYSTEM
1. Keep all hydraulic components free of dirt,
grease, chips, etc.
2. Keep the hydraulic component operating in areas
that are uncluttered and free of unnecessary
equipment.
3. Periodically check your hydraulic system for
possible loose connections, leaks, etc. Replace
or properly repair damaged or leaking hydraulic
components immediately.
4. Check hydraulic oil in your hydraulic system
every 40 hours of operation or more frequently in
unusually dirty or dusty areas.
5. Oil temperature must be maintained less than or
equal to 150 °F (65 °C) by way of a heat
exchanger or other methods.
8.0 TROUBLESHOOTING
1. If the system will not build pressure, check relief
valves in pump for proper setting (refer to pump
repair sheet). Check and secure all hose
connections. If trouble is not corrected by this
action, remove cylinder and hoses from valve.
Now place a 10,000 PSI gauge directly in valve
port "A" and depress the "up" arrow button. If
pressure cannot be developed, the unit should be
taken to the nearest ENERPAC authorized service
center. If pressure develops, the problem is
located in the cylinder, hoses, or couplers.
2. For VE32 only. After advancing the load, the load
will automatically be held in place. If load drifts,
the unit should be taken to the nearest Enerpac
authorized Service Center.
3. Refer to Repair Parts Sheet L2612 for
"troubleshooting" suggestions.
9.0 STORAGE INSTRUCTIONS
In the event that the unit would be stored for any
prolonged period of time (30 days or more), prepare
the unit as follows:
1. Wipe the entire unit clean.
2. Disconnect all hydraulic and electrical lines to
prevent accidental operation.
3. Cover the unit with some kind of protective cover.
4. Store in a clean, dry environment that is NOT
exposed to extreme temperatures.
