Inspect the Fuel and Hydraulic
Tank Cap Venting Systems
Genie specifications require that
this procedure be performed every
250 hours or quarterly, whichever
comes first. Perform this
procedure more often if dusty
conditions exist.
Free-breathing fuel and hydraulic tank caps are
essential for good machine performance and
service life. A dirty or clogged tank cap may cause
the machine to perform poorly and continued use
may cause component damage. Extremely dirty
conditions may require that the caps be inspected
more often.
Explosion and fire hazard. Engine
fuels are combustible. Perform this
procedure in an open, well-
ventilated area away from heaters,
sparks, flames and lighted
tobacco. Always have an approved
fire extinguisher within easy reach.
Perform this procedure with the
engine off.
