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.
