# 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 压力表内注入了液体。如果此液位下降，表示有外部泄漏，需要更换。如果压力表内出现液压油，表示有内部损坏，不应继续使用。

- 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.

- 遥控器 (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: 每 2 年应对泵进行一次彻底检查。可以由 TITAN 或合格的液压维护中心进行检查。
