Test or Replace the Hydraulic Oil

Note: Genie requires that this procedure be
performed every 2000 hours or two years,
whichever comes first.
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: The machine uses Dexron equivalent
hydraulic oil. 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: Perform this procedure with the boom in the
stowed position.

tank. Refer to Section 2, Specifications .
