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.

Inspect the Hydraulic Filters
Genie specifications require that this procedure be
performed quarterly.
Maintaining the hydraulic filter in good condition is
essential to good system performance and safe
machine operation. The filter condition indicator
will show when the hydraulic flow is bypassing a
clogged filter. If the filter is not frequently checked
and replaced, impurities will remain in the
hydraulic system and cause component damage.
Note: There are four types of hydraulic filters: tank
return filter, medium pressure filter, high pressure
filter and drive motor case drain filter. The quantity
and type of filter(s) may vary by model.
Models with Filter Condition Indicator:
1
Start the engine from the ground controls.
2
Set the engine idle to high rpm (rabbit
symbol).
3
Visually inspect the filter condition indicator.
Result: The filter condition indicator is
operating in the green area.
Result: The filter condition indicator is
operating in the red area. This indicates that
the hydraulic filter is being bypassed and the
filter should be replaced. Refer to
Maintenance Procedure, Replace the
Hydraulic Filters.
