SAFETY INFORMATION
EBU00193
AN ATV IS NOT A TOY AND CAN BE HAZARD-OUS 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 training
or instruction.


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


Never allow a child under age 16 to operate an
ATV without adult supervision, and never allow
continued use of an ATV by a child if he or she
does not have the abilities to operate it safely.

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. Other-
wise, 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.

quate ventilation. Never start or run the engine
