Replace the Hydraulic Filters
Genie requires that this procedure be performed
every 2000 hours.
Perform this procedure more often if dusty
conditions exist.
Replacement of the hydraulic filters is essential for
good machine performance and service life. A dirty
or clogged filter may cause the machine to perform
poorly and continued use may cause component
damage. Extremely dirty conditions may require
that the filter be replaced more often.
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.
Bodily injury hazard. Beware of
hot oil. Contact with hot oil may
