Replace the Hydraulic Filter
Elements
Genie specifications require that this procedure be
performed every 1000 hours or annually,
whichever comes first. 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 filters be replaced more often.
Bodily injury hazard. Beware of
hot oil. Contact with hot oil may
cause severe burns.
Note: Perform this procedure with the engine off.
