Preventive Maintenance - Hydraulic Power Packs
HYTORC Hydraulic Power Packs are precision-built units and, as such, 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 lled with uid. If additional oil is required, use only high-grade hydraulic oil.
Consult your local waste ordinace requirements for proper disposal of hydraulic oil. Most environmental
regulations prohibit the disposal of the hydraulic oil through ordinary means. Precaution should be taken
and hydraulic oil should be disposed of as hazardous when ever the local requirements are not clear.
• Quick-Disconnects
Fittings should be checked periodically for leaks. Dirt or foreign materiais should be kept away from ttings.
Clean before use.
• Hydraulic Gauge
Some gauges are liquid lled. Should this liquid level drop, it indicates external leakage, and replacement is
necessary. Should the gauge ll with hydraulic oil, it indicates internal failure and it should be discarded.
• Filter on Pump
The lter 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 air line 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 difculties. (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.
