B-4
Perform Hydraulic Oil Analysis
Genie requires 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 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. Refer to Section 2,
Specifications
.
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
