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.

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

Throttle lever
Once the engine is running, movement of the
throttle lever will increase the engine speed.
Regulate the speed of the machine by varying the
throttle position. Because the throttle is spring-
loaded, the machine will decelerate, and the en-
gine will return to an idle any time the hand is re-
moved from the throttle lever.
Before starting the engine, check the throttle to be
sure it is operating smoothly. Make sure it returns
to the idle position as soon as the lever is released.
WARNING
Malfunction of the throttle could make it diffi-
cult to speed up or slow down when you need
to. This could cause an accident. Check the
operation of the throttle lever before you start
the engine. If the throttle does not work
smoothly, check for the cause. Correct the
problem before riding the ATV or consult a
Yamaha dealer.
