2.2 FUEL SYSTEM
WARNING
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. Do not fill the tank neck.
If you get gasoline in your eyes or if you swallow gasoline, see your doctor immediately.
If you spill gasoline on your skin or clothing, immediately wash it off with soap and water
and change clothing.
Never start the engine or let it run in an enclosed area. Gasoline powered engine exhaust
fumes are poisonous and can cause loss of consciousness and death in a short time.
Never drain the float bowl when the engine is hot. Severe burns may result.
