8Always turn off the engine when refueling.
8Do not refuel immediately after the engine
has been running and is still very hot.
8Do not spill gasoline on the engine or
exhaust pipe/muffler when refueling.
Never refuel while smoking or in the vicini-
ty of sparks, open flames, or other
sources of ignition such as the pilot lights
of water heaters and clothes dryers.
Gasoline can catch fire. You could be
burned.
8When transporting the machine in another
vehicle, be sure it is kept upright and that
the fuel cock is in the “OFF” position.
Otherwise, fuel may leak out of the carbu-
retor or fuel tank.
8Gasoline is poisonous. If you should swal-
low some gasoline or inhale a lot of gaso-
line vapor, or get some gasoline in your
eyes, see your doctor immediately. If
gasoline spills on your skin, wash with
soap and water. If gasoline spills on your
clothing, change your clothes.
