Replace the Hydraulic Tank
Return Filter
Genie specifications require that this procedure be
performed every 1000 hours or annually,
whichever comes first.
Replacement of the hydraulic tank return filter 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.
Beware of hot oil. Contact with hot
oil may cause severe burns.
Note: Perform this procedure on a firm, level
surface.
