1nition such as the pilot lights of water heat-
ers and clothes dryers. Gasoline can catch
fire and you could be burned.

When transporting the ATV in another vehi-
cle, be sure it is kept upright and that the fuel
cock is in the “OFF” position. Otherwise, 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 gasoline
vapor, or get some gasoline in your eyes,
seek medical help immediately. If gasoline
spills on your skin, wash with soap and wa-
ter. If gasoline spills on your clothing,change your clothes.
WARNING
EWB00070Always operate your ATV in an area with ade-
quate ventilation. Never start or run the engine
in a closed area. Exhaust fumes are poisonous
and may cause loss of consciousness anddeath within a short time.

To release the differential gear lock, stop the ATV
and push the switch to the “4WD” position.
WARNING
EWB00130Always stop the ATV before changing from
four-wheel drive to four-wheel-drive differen-
tial gear lock or vice-versa.
The ATV handles differently in four-wheel drive
than in differential gear lock in some circum-
stances. Changing from four-wheel drive to dif-
ferential gear lock or vice-versa while moving
may cause the ATV to handle differently unex-pectedly. This could distract the operator and
increase the risk of losing control and causing
an accident.
WARNING
EWB00140Always ride at a slow speed when the ATV is in
differential gear lock, and allow extra time and
distance for maneuvers.
All wheels turn at the same speed when the dif-
ferential gear is locked, so it takes more effort
to turn the ATV. The effort needed to turn in-
creases with the riding speed. You may lose
control and have an accident if you cannot
make a sharp enough turn for the speed youare traveling.NOTE:
When the switch is set to “LOCK”, the differential
gear lock indicator and indicator light will flash
until the differential gear is locked.
When the indicator and indicator light are flash-
ing, turning the handlebar back and forth will
help the differential gear lock to engage.

Riding before the differential gear lock is proper-
ly engaged (e.g., when the indicator and indica-
tor light are flashing) will cause the engine speed
to be limited until engagement is complete.
When the ATV is in four-wheel-drive differential
gear lock, the maximum traveling speed is limit-
ed to 35 km/h (22 mi/h). However, if conditions
require full engine power to be available, push
and hold the override switch to disable the differ-
ential gear lock speed limiter. (See page 4-7 fora detailed explanation of this switch.)EBU18280Throttle lever Once the engine is running, movement of the throt-
tle lever will increase the engine speed.
Regulate the speed of the ATV by varying the
throttle position. Because the throttle is spring-
loaded, the ATV 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.
WARNING
EWB00250Malfunction 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 op-
eration of the throttle lever before you start the
engine. If the throttle does not work smoothly,
check for the cause. Correct the problem be-fore riding the ATV or consult a Yamaha dealer.1. Throttle lever

OPERATION
EBU19900Read the Owner’s Manual carefully before riding
the ATV.
WARNING
EWB00630Read the Owner’s Manual carefully to become
familiar with all controls in order to help pre-
vent any loss of control, which could cause an
accident or injury. If there is a control or func-
tion you do not understand, ask your Yamahadealer.EBU20052Starting a cold engine
WARNING
EWB00640Always make sure all control cables work
smoothly before you begin riding in cold
weather. If the control cables are frozen or do
not work smoothly, you could be unable to
control the ATV, which could lead to an acci-dent or collision.
CAUTION:ECB00150See the “Engine break-in” section on page 6-5prior to operating the engine for the first time.
1. Turn the fuel cock to “ON”.
2. Turn the main switch to “ON” and the engine
stop switch to “”.
3. Shift the drive select lever into the neutral or
park position. The corresponding indicator
light should come on. If the indicator light does
not come on, have a Yamaha dealer check
the electrical circuit.NOTE:The engine can be started under the following con-
ditions:
The drive select lever is in the neutral or park po-
sition.
The rear brake lever is applied with the drive se-
lect lever in any position. However, it is recom-
mended to shift into the neutral or park positionbefore starting the engine.

7 With the engine idling, shift the drive select lever
into the low-range position or the high-range posi-
tion. Apply the throttle slowly and smoothly. The
centrifugal clutch will engage and you will start to
accelerate. If the throttle is applied too abruptly, the
front wheels may lift off the ground, resulting in a
loss of directional control. Avoid higher speeds un-
til you are thoroughly familiar with the operation of
your ATV.
When slowing down or stopping, release the throt-
tle and apply the brakes smoothly and evenly. Im-
proper use of the brakes can cause the tires to lose
traction, reducing control and increasing the possi-
bility of an accident.
CAUTION:ECB00250Do not shift from drive position low-range to
high-range or vice versa without coming to a
complete stop. Damage to the engine or drivetrain may occur.
TURNING YOUR ATV
To achieve maximum traction on unpaved surfac-
es in 2WD or 4WD, the two rear wheels turn to-
gether at the same speed. Furthermore, when
riding in 4WD-LOCK (“DIFF. LOCK”), the frontwheels also turn together at the same speed.
Therefore, unless the wheel on the inside of the
turn is allowed to slip or lose some traction, the
ATV will resist turning. A special turning technique
must be used to allow the ATV to make turns
quickly and easily. It is essential that this skill be
learned first at low speed.
WARNING
EWB01770Always follow proper procedures for turning
as described in this Owner’s Manual. Practice
turning at low speeds before attempting to turn
at faster speeds. Do not turn at speeds too fast
for your skills or the conditions. Operate at a
slow speed and allow extra time and distance
for maneuvers when in 4WD-LOCK (“DIFF.LOCK”).
As you approach a curve, slow down and begin to
turn the handlebars in the desired direction. As you
do so, put your weight on the footboard to the out-
side of the turn (opposite your desired direction)
and lean your upper body into the turn. Use the
throttle to maintain an even speed through the turn.
This maneuver will let the wheel on the inside of
the turn slip slightly, allowing the ATV to make the
turn properly.
