PROCEDURES
B-15
Perform Hydraulic Oil Analysis
Note: Genie specifications require that this
procedure be performed every 250 hours or
quarterly, 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: 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.
See E-1,
Test or Replace the Hydraulic Oil.
