Visual Inspection of the Hydraulic
Oil
Genie specifications require 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 and a clogged suction strainer
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. For hydraulic oil
specifications, Refer to Specifications,
Hydraulic
Specifications .
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. Replace the oil when it fails the
test. Refer to Maintenance Procedure,
Test or
Replace the Hydraulic Oil .
1 Collect a sample of hydraulic oil and place in
a clear container. Visually inspect the
hydraulic oil for the following:
•
Color: oil should be a clear, light-honey
colored
•
Appearance, oil should be clear and not
cloudy or visibly distorts the view through
the sight glass or container
•
Contains no particles, foreign objects, or
other contamination
•
The hydraulic oil can be inspected by smell
(can smell “hot” but not “burnt”) or rubbing
between fingers (should feel viscous and
free of any rough feel due to particles)
If the hydraulic oil passes all of the above
inspections, continue the scheduled
maintenance intervals.
If the hydraulic oil fails any of the above
inspections, the hydraulic oil must be tested
by an oil distributor or replaced.
Note: If the hydraulic oil was not replaced at or
before 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. After the
oil has been replaced, continue the scheduled
quarterly maintenance inspection.
Note: When replacing the hydraulic oil, it is
recommended that all hydraulic filters be replaced
at the same time.
