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 often.
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.
