Draining the Fuel Tank

In certain conditions, fuel is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and
others and can damage property.
• Drain fuel from the fuel tank when the
engine is cold. Do this outdoors in an
open area. Wipe up any spills.
• Never smoke when draining fuel, and
stay away from an open flame or where a
spark may ignite the fumes.
1. Park the traction unit on a level surface, to
ensure that the fuel tanks drain completely.
2. Lower the loader arms and stop the engine.
Remove the key.
3. Shut off the fuel valve in the hose near the
bottom of the fuel tank as illustrated in
Figure 32.
