GUIDE)

Only qualifi ed hydraulic technicians should service the pump or

system components. A system failure may or may not be the result

of a pump malfunction. To determine the cause of the problem, the

complete system must be included in any diagnostic procedure.

The following information is intended to be used only as an aid in

Figure 12, Relief Valve Adjustment

determining if a problem exists. For repair service, contact your

local Authorized Enerpac Service Center.

6.0 MAINTENANCE

Frequently inspect all system components for leaks or damage.

Repair or replace damaged components.

6.1 Check Oil Level

Check the oil level of the pump prior to start-up, and add oil, if

necessary, by removing the fi ll port cap. Always be sure hydraulic

wrenches are fully retracted before adding fl uid to the reservoir.

See Figure 2.

6.2 Change Oil and Clean Reservoir

Enerpac HF oil is a crisp blue color. Frequently check oil condition

for contamination by comparing pump oil to new Enerpac oil. As

a general rule, completely drain and clean the reservoir every 250

hours, or more frequently if used in dirty environments.

NOTE: This procedure requires that you remove the pump from

the reservoir. Work on a clean bench and dispose of used oil

according to local codes.

1. Unscrew the 13 bolts holding the coverplate to the reservoir

and lift the pump unit out of the reservoir. Be careful not to

damage the fi lter screen.

2. Pour all oil out of the reservoir.

3. Thoroughly clean the reservoir and reservoir magnet with a

suitable cleaning agent.

4. Remove the pick-up fi lter screen for cleaning. (Do not pull

on the screen or the bottom of the intake to avoid possible

damage.) Clean the screen with solvent and a soft brush.

Reinstall.

5. Reassemble the pump and reservoir, installing a new reservoir

gasket.

6. Fill the reservoir with clean Enerpac hydraulic oil. The reservoir is

full when oil level is in middle of the sight gauge (see fi gure 4).
