Checklist E Procedures; Test Or Replace The Hydraulic Oil - Genie Z-34/22 Service Manual

Test or Replace the Hydraulic Oil

Genie specifications require that this procedure be
performed every 2000 hours or every two years,
whichever comes first.
Perform this procedure more often if dusty
conditions exist.
Replacement or testing of the hydraulic oil is
essential for good machine performance and
service life. Dirty oil and a clogged suction strainer
or hydraulic filters may cause the machine to
perform poorly and continued use may cause
component damage. Extremely dirty conditions
may require oil changes to be performed more
frequently.
Note: Before replacing the hydraulic oil, the oil may
be tested by an oil distributor for specific levels of
contamination to verify that changing the oil is
necessary. If the hydraulic oil is not replaced at the
two year inspection, test the oil quarterly. Replace
the oil when it fails the test.
Note: When removing a hose assembly or fitting,
the O-ring (if equipped) on the fitting and/or hose
end must be replaced. All connections must be
torqued to specification during installation. Refer to
Specifications, Hydraulic Hose and Fitting Torque
Specifications.
Note: Perform this procedure with the boom in the
stowed position.
1 Close the two hydraulic tank shut-off valves at
the hydraulic tank.
Component damage hazard.
The machine must not be
operated with the hydraulic tank
shutoff valve in the closed
position or component damage
will occur. If the tank valve is
closed, remove the key from the
key switch and tag the machine
to inform personnel of the
condition.
