applicable local and national codes.
Daily
•
Check the pump and hoses for oil leaks.
•
Check the oil level of the pump prior to start-up, and add oil, if necessary, by removing the fill port cap. Always be sure
that the placing tool piston is fully returned before adding fluid to the reservoir. Refer to page

4.2 CHANGE OIL AND CLEAN RESERVOIR
•
Enerpac
®
HF oil is a crisp blue colour. 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.
•
Unscrew the 13 bolts holding the cover plate to the reservoir and lift the pump unit out of the reservoir. Be careful not to
damage the filter screen.
•
Pour all oil out of the reservoir.
•
Thoroughly clean the reservoir and reservoir magnet with a suitable cleaning agent.
•
Remove the pick-up filter 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.
•
Reassemble the pump and reservoir, installing a new reservoir gasket.
•
Fill the reservoir with clean Enerpac ® hydraulic oil. The reservoir is full when oil level is in middle of the sight gauge.
