PREVENTIVE MAINTENANCE -
Hydraulic Power Packs
:
WREN's Hydraulic Power Packs are precision-built hydraulic unit and, as
such, do require a certain amount of care and maintenance.
1.
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, such as Shell " Tellus oil"#46, Exxon " Teresstic"#46, Aral " Vitam DE"
#46 oder vergleichbares.
2.
Quick-Disconnects
: Fittings should be checked periodically for leaks.
Dirt and foreign materials should be kept away from fittings. Clean before
use.
3.
Hydraulic Gauge
: Gauges are liquid filled. Should this liquid level drop,
it indicates external leakage, and replacement it necessary. Should the
Gauge fill with hydraulic oil, it indicates internal failure and should be
discarded.
4.
Filter on Pump
: The filter should be replaced twice a year for normal
use, and more often if pump is in daily use.
5.
Directional Control Valve
: Should malfunctioning occur, disassemble,
inspect, and clean.
6.
Motor
: The motor shaft and bearings should be flushed and lubricated
once year.
7.
Pumping Unit
: The Pumping Unit should be overhauled every 2 years.
This can be done by WREN or by a qualified hydraulic service center.
