WARNING
_

Always turn off the engine when refueling.


Do not refuel immediately 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 in the vicinity of
sparks, open flames, or other sources of
ignition such as the pilot lights of water
heaters and clothes dryers. Gasoline can
catch fire and you could be burned.


When transporting the ATV in another ve-
hicle, be sure it is kept upright and that
the fuel cock is in the “OFF” position. Oth-
erwise, fuel may leak out of the carburetor
or fuel tank.


Gasoline is poisonous. If you should
swallow some gasoline or inhale a lot of
gasoline 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.
