6.0 TROUBLE SHOOTING
1. System will not build pressure. Check relief valve in the
control valve or in the pump, for proper setting (see pump
repair sheet or valve repair sheet). Check and secure all hose
connections. If trouble is not corrected, remove cylinder and
hoses from the valve. Now place a gauge directly in valve port
A and place the valve in advance. If pressure cannot be
developed, the unit should be taken to the nearest authorized
ENERPAC Service Center. If pressure develops, the cylinder,
hoses or couplers are the problem.
2. The cylinder will not hold load. This is an indication of worn
valve seals or load holding check valve that must be replaced
by an authorized Enerpac Service Center.
7.0 MAINTENANCE
1. Periodically check all hydraulic and air 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.
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.

8.0 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.

9.0 STORAGE INSTRUCTIONS

In the event that the unit would be stored for any great length of
time (30 days or more), prepare as follows:
1. Wipe the entire unit clean.
2. Disconnect all hydraulic lines to prevent accidental operation.
3. Cover the unit with some type of protective cover.
4. Store in a clean, dry environment that is NOT exposed to
extreme temperatures.
