Test or Replace the Hydraulic Oil

Genie requires that this procedure be performed
every 2000 hours or every 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
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.
Note: Perform this procedure with the platform in
the stowed position.
1 Disconnect the battery pack from the machine.
Electrocution/burn hazard. Contact
with electrically charged circuits
could result in death or serious
injury. Remove all rings, watches
and other jewelry.
2 Open the power unit module tray.
