WARNING
Always turn off the engine when refuel-
ing.
Do not refuel right after the engine has
been running and is still very hot.
Do not spill gasoline on the engine or ex-
haust pipe/muffler when refueling. Never
refuel while smoking, or while in the vi-
cinity of sparks, open flames, or other
sources of ignition such as the pilot lights
of water heaters and clothes dryers. Gas-
oline can catch fire and you could be
burned.
When transporting the machine in anoth-
er 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.
Gasoline 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 gas-
oline spills on your skin, wash with soap
and water. If gasoline spills on your cloth-
ing, change your clothes.
