Inspect the Fuel and Hydraulic
Tank Cap Venting Systems
Genie requires 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.
Note: For machines located in the United States,
EPA Certificate 40 CFR Part 1060 requires that the
fuel tank cap be in proper working condition.
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.
