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.
