Oil and Fuel

POTENTIAL HAZARD
• In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
• A fire or explosion from gasoline can
burn you, others, and cause property
damage.
HOW TO AVOID THE HAZARD
• Use a funnel and fill the fuel tank
outdoors, in an open area, when the engine

the bottom of the filler neck. This empty
space in the tank allows gasoline to
expand.

and stay away from an open flame or
where gasoline fumes may be ignited by a
spark.
• Store gasoline in an approved container
and keep it out of the reach of children.
• Never buy more than a 30-day supply of
