Fuel Tank Service

Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
Drain gasoline from the fuel tank when the
engine is cold. Do this outdoors in an open area.
Wipe up any gasoline that spills.
Never smoke when draining gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
Draining The Fuel Tank
1. Park the machine on a level surface, to assure fuel tank
drains completely. Then disengage the power take off
(PTO) and turn the ignition key to "OFF" to stop the
engine. Remove the key.
2. Close fuel shut–off valve (Fig. 32).
Note: Remove fuel line from fuel valve that is closest to
the engine.
3. Squeeze the ends of the hose clamp together and slide
it away from valve (Fig. 32).
4. Pull the fuel line off the valve (Fig. 32). Open fuel
shut-off valve and allow gasoline to drain into a gas
can or drain pan.
