# 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: TITAN-mätare är vätskefyllda. Skulle denna vätskenivå sjunka, betyder det ett yttre läckage, och den måste bytas ut. Om mätaren fylls med hydraulolja, betyder det ett internt fel och den ska kasseras.

- 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.

- Fjärrkontroll (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: Pumpen bör ses över vartannat år. Detta kan göras av TITAN eller av ett kvalificerat hydrauliskt servicecenter.
