Test or Replace the Hydraulic Oil
Genie specifications require 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 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. Refer to Section 2,
Specifications.
Component damage hazard. The
work area and surfaces where this
procedure will be performed must
be clean and free of debris that
could get into the hydraulic
system.
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.
