Troubleshooting Powerpacks

Atlas Copco Hydraulic Power Packs are precision-built units and, as such, do require a certain amount of care and maintenance

Hydraulic Oil should be completely changed after every 300 hours of operation, or at least twice a year. Always make sure the reservoir is filled with fluid. Always use Atlas Copco Maximizer range of oils for best performance.
Couplers and fittings should be checked periodically for leaks. Dirt or foreign materials should be kept away from fittings. Clean before use.
Hydraulic Gauge: Some gauges are liquid filled. Should this liquid level drop, it indicates external leakage, and replacement is necessary. Should the gauge fill with hydraulic oil, it indicates internal failure and it should be discarded.
Filter on Pump: The filter should be replaced twice a year in normal use and more often if the pump is used daily or in a dirty, harsh environment.
Remote Control: (Air Unit) The airline to the remote control unit should be checked for obstructions or kinks in the line periodically. If there is a bend or break in the line, it must be replaced. The spring- loaded buttons on the remote handle should be checked in the event of operating difficulties. (Electric Unit) The switch buttons should be checked periodically if any indications of problems exist.
Air Valve: This valve should be checked twice a year.
Armature: (Electric Unit) Check yearly.
Pumping unit: The pump should be overhauled every 2 years. This can be done by Atlas Copco or by a qualified hydraulic service centre.
