Draining the Fuel Tank
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.
1. Park the machine on a level surface and
disengage the blade control switch.
2. Move the motion control levers outward to the
park position, stop the engine, remove the key,
and wait for all moving parts to stop before
leaving the operating position.
3. Close the fuel shut-off valve located under the
front of the fuel tank (Figure 30).
