Perform Hydraulic Oil Analysis
DINGLI requires that this procedure be
performed every 250 hours or quarterly,
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.
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. See E-1, Test or
Replace the Hydraulic Oil.
