P2-2
Test or Replace the Hydraulic Oil
Genie requires that this procedure be performed
every 2000 hours.
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
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
2000 hour inspection, test the oil quarterly.
Replace the oil when it fails the test.
Note: When removing a hose assembly or fitting,
the O-ring (if equipped) on the fitting and/or hose
end must be replaced. All connections must be
torqued to specification during installation. Refer to
Specifications, Hydraulic Hose and Fitting Torque
Specifications.

Testing the oil:
1 Complete the hydraulic oil testing with an oil
distributor.
If the hydraulic oil passes testing at the 2000
hour maintenance interval, the oil must be
tested every quarter by an oil distributor until
the oil fails the test and is replaced.
If the hydraulic oil fails testing at the 2000
hour maintenance interval, the oil must be
replaced. After the oil has been replaced,
continue the scheduled quarterly maintenance
inspection.
Replacing the hydraulic oil:
1 Remove the drain plug from the hydraulic tank
and completely drain the tank into a container
of suitable capacity. Refer to Specifications,
Hydraulic Fluid Capacities Specifications.
2 Fill the tank with the proper hydraulic oil for
your machine. Refer to Specifications,
Hydraulic Specifications.
3 Engine Models: Prime the pump. Refer to
Repair Procedure in the appropriate Service
and Repair Manual for your machine, How to
Prime the Pump.
4 Clean up any oil that may have spilled.
Note: When replacing the hydraulic oil, it is
recommended that the hydraulic tank be cleaned
using a mild solvent and all hydraulic filters and
strainers be replaced.
Note: Always use pipe thread sealant when
installing the suction hose fittings and the drain
plug.
Note: After the oil has been replaced, continue the
scheduled quarterly maintenance inspection.
