Gasoline is extremely flammable and explosive
under certain conditions.
. Always stop the engine and refuel outdoors or in a
well-ventilated area.
. Do not smoke or allow open flames or sparks in or
near the area where refueling is performed or where
gasoline is stored.
. Do not overfill the tank.
. Fill the tank to the bottom of the filler neck.
. This will allow for thermal expansion.

gasoline, see your doctor immediately.

immediately wash it off with soap and water and
change clothing.
. Never start the engine or run it in an enclosed area
