Inspect the Fuel and Hydraulic
Tank Cap Venting Systems
Genie specifications require that this procedure be
performed quarterly or every 250 hours, whichever
comes first. Perform this procedure more often if
dusty conditions exist.
A free-breathing fuel and hydraulic tank cap is
essential for good machine performance and
service life. A dirty or clogged cap may cause the
machine to perform poorly and continued use may
cause component damage. Extremely dirty
conditions may require that the cap be inspected
more often.
