Test or Replace the Hydraulic Oil

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.
The machine uses Dexron
equivalent hydraulic oil. 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.
Perform this procedure with the
boom in the stowed position.
When removing a hose assembly
or fitting, the O-ring on the fitting
and/or hose end must be replaced
and then torqued to specification
during installation.
Refer to Section Two, Hydraulic
Hose and Fitting Torque
