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. Refer to Section
2, Specifications.
Component damage hazard. The
work area and surfaces where this
procedure will be performed must
be clean and free of debris that
could get into the hydraulic
system.
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.
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
Specifications.
In extreme cold conditions,
20°F / -6°C and below, warm the
engine for 5 minutes before
operating to prevent hydraulic
system damage.
1 Turn the key switch to ground controls and pull
out the red Emergency Stop buttons to the on
