Perform Hydraulic Oil Analysis

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 frequently.
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.

Inspect the Boom
Extend/Retract Cables
Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
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 and related components 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.
1 Raise the boom to horizontal and fully extend
the boom.
2 After the boom is fully extended, lower the boom
until the platform is at chest height. Turn the
machine off.
3 Remove the boom end cover retaining fasteners
and remove the cover.
4 Remove the retaining fasteners from the access
covers located on the side of the boom at the
platform end of the machine. Remove the
covers.
