DANGER
POTENTIAL HAZARD
• In certain conditions gasoline is extreme-
ly 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 out-
doors, in an open area, when the engine

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
gasoline.
