Test or Replace the Hydraulic Oil

Genie requires 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 suction strainers 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 often.
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 the
hose end must be replaced. All connections must
be torqued to specification during installation. Refer
to Section 2, Hydraulic Hose and Fitting Torque
Specifications .
Note: Perform this procedure with the boom in the
stowed position.
