WARNING
_

Always turn off the engine when refueling.


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 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 and you could be burned.


When transporting the machine in another
vehicle, 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 swal-
low some gasoline or inhale a lot of gaso-
line vapor, or get some gasoline in your
eyes, see your doctor immediately. If gaso-
line spills on your skin, wash with soap
and water. If gasoline spills on your cloth-
ing, change your clothes.

Coolant temperature warning light “”
When the coolant temperature reaches a specified
level, this light comes on to warn that the coolant
temperature is too hot. If the light comes on during
operation, stop the engine as soon as it is safe to
do so and allow the engine to cool down for about
10 minutes.
To check the coolant temperature warning light,
shift the drive select lever into neutral, turn the key
to “ON”, and then press the start switch. If the light
does not come on, have a Yamaha dealer inspect
the electrical circuit.CAUTION:_

The engine may overheat if the ATV is
overloaded. If this happens, reduce the
load to specification.


Restart after making sure that the light is
out. Continuous use while the light is on
may cause damage to the engine.
