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.
