Preventive Maintenance -
Hydraulic Power Packs
TORC, LLC. Hydraulic Power Packs are precision-built units and, as such, do require a certain amount of care and
maintenance.
• Hydraulic Oil
Oil should be completely changed after every 40 hours of operation, or at least twice a year. Always make sure the
reservoir is filled with fluid. If additional oil is required, use only high-grade hydraulic oil.
• Quick-Disconnects
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 rocker switch should be checked periodically if
any indication of problems exist.
• Air Valve
This valve should be checked twice a year.
• Brushes and Brush Holders
(Electric Unit) Check and replace, if worn.
• Armature
(Electric Unit) Check yearly.
