Inspect the Fuel and Hydraulic
Tank Cap Venting Systems
Genie specifications require that this procedure be
performed quarterly.
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.
Note: Perform this procedure with the engine off.
GTH-636 and GTH-844
1 Identify the vent tube breather from the fuel
tank under the chassis center cover.
2 Check for proper venting.
Result: Air passes through the vent tube.
Proceed to Hydraulic Tank Breather Cap.
Result: If air does not pass through the vent
tube, clean or replace the tube. Proceed to
step 3.
Note: When checking for positive tank cap venting,
air should pass freely through the tube.
3 Using a mild solvent, carefully wash the tube
venting system. Dry using low pressure
compressed air. Repeat this procedure
beginning with step 2.
