SAFETY INFORMATION
AN ATV IS NOT A TOY AND CAN BEHAZARDOUS TO OPERATE.
An ATV handles
differently from other vehicles including
motorcycles and cars. A collision or rollover can
occur quickly, even during routine maneuvers
such as turning and riding on hills or over
obstacles, if you fail to take proper precautions.
SEVERE INJURY OR DEATH can result if you do
not follow these instructions:


Read this manual and all labels carefully and
follow the operating procedures described.


Never operate an ATV without proper instruc-
tion.


Always follow the age recommendation:
– A child under 16 years old should never oper-
ate an ATV with engine size greater than 90cc.

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.
