AN ATV IS NOT A TOY AND CAN BE HAZ-
ARDOUS 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 precau-
tions.
SEVERE INJURY OR DEATH can result if you
do not follow these instructions:
8Read this manual and all labels carefully and
follow the operating procedures described.
8Never operate an ATV without proper instruc-
tion.
8Always follow the age recommendation:
– A child under 16 years old should never
operate an ATV with engine size greater
than 90cc.

8Always maintain proper tire pressure as
described in this manual.
8Never modify an ATV through improper instal-
lation or use of accessories.
8Never exceed the stated load capacity for an
ATV. Cargo should be properly distributed
and securely attached. Reduce speed and fol-
low instructions in this manual for carrying
cargo or pulling a trailer. Allow greater dis-
tance for braking.
w
Always turn off the engine when refueling.
8Do not refuel right after the engine has
been running and is still very hot.
8Do not spill gasoline on the engine or
exhaust pipe/muffler when refueling.
Never refuel while smoking, or while 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. You could be
burned.

8When transporting the machine in another
vehicle, be sure it is kept upright and that
the fuel cock is in the “OFF” position.
Otherwise, fuel may leak out of the carbu-
retor or fuel tank.
8Gasoline 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
gasoline spills on your skin, wash with
soap and water. If gasoline spills on your
clothing, change your clothes.
w
Always operate your machine in an area with
adequate ventilation. Never start or run the
engine in a closed area. Exhaust fumes are
poisonous and may cause loss of con-
sciousness and death within a short time.

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 engine will return to an idle any time the
hand is removed 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.
w
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.

Throttle OverRide System
If during operation, the carburetor or the throttle
cable should malfunction and will not close fully,
take your thumb off the throttle lever.
The throttle override system immediately cuts off
the ignition.
w
Riding with a malfunction increases the
chance for an accident and injury. Make sure
that the cause of the malfunction is correct-
ed before restarting the engine or have the
ATV inspected by a Yamaha dealer.
