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 and a clogged suction strainer
or hydraulic filters 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.
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.

Inspect the Boom Extend/
Retract Cables
The boom extend/retract cables are responsible for
the extension and retraction of the number 3 boom
tube. Inspecting for foreign objects, damage and/or
improper adjustment of the boom extend/retract
cables on a regular basis is essential to good
machine performance and safe machine operation.
The boom extend and retract functions should
operate smoothly and be free of hesitation, jerking
and unusual noise.
