Changing the hydraulic oil
This is the accepted procedure for changing hydraulic
oil. Your oil supplier can tell you how to properly dis-
pose of used hydraulic oil.
Service steps
WARNING
Place the main electrical disconnect in the OFF
position and bleed down all high-pressure lines.
Place an
Out of Service
tag on the main electrical
disconnect and lock it out. Failure to do so can result
in equipment damage or injury to personnel.
1. Shut down the system.
2. Use a hose to drain the oil from the reservoir drain
valve into a container large enough to hold 37 gal
(140 L).
3. Remove the access cover from the reservoir and
thoroughly wipe clean the inside surfaces of the res-
ervoir.
•
If the oil was contaminated with metal particles
because of a pump or hydraulic piston failure,
see
Cleaning a contaminated oil system.
CAUTION
You must thoroughly clean the reservoir after metal
flakes have been pumped through it or the pump,
intensifier, shift valve, pilot valve, shift cables,
pressure control valves, and other components can
fail. Your warranty does not cover this damage.
4. Change the hydraulic oil filter. See
Replacing the
hydraulic oil filter.
