Maintenance and Servicing

IMPORTANT - Only fully trained and qualified hydraulic technicians should service the pump or system components.
Please contact Avdel ® for your servicing, repair and training requirements. Service Instructions and repair parts sheet
are available on request.
The following checks and maintenance must be carried out on a regular basis.
Frequently inspect all system components for leaks or damage. Repair or replace damaged components. Electrical
components, for example, the power-cord, may only be repaired or replaced by a qualified electrician, adhering to all
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 11 and 12.
•
Check the stroke of the placing tool.
• Check the function of the High Pressure relief valve.
Weekly
•
Check for wear and tear on trailing cable.
•
Check for wear and tear on umbilical sleeve, trigger control cable and hydraulic hoses.
• Check for leakage and/or wear and tear on hydraulic quick connectors.
•
Check tightness of hydraulic fittings and fasteners on the pump unit.
• Check for oil contamination.
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.
