Replace the Hydraulic Filters

Genie requires that this procedure
be performed yearly or every 1000
hours, 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.
Perform this procedure with the
engine off.
