w
Always check the brakes at the start of every
ride. Do not ride the ATV if you find any
problem with the brakes or you could lose
braking ability, which could lead to an acci-
dent. If a problem cannot be corrected by the
adjustment procedures provided in this man-
ual, have the ATV inspected by a Yamaha
dealer.

Starting a cold engine
w
Always 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
accident or collision.
1. Set the parking brake.
2. Turn the fuel cock to “ON”.
3. Turn the main switch to “ON” and the
engine stop switch to “RUN”.
4. Shift the transmission into neutral.

NOTE:
This model is equipped with an ignition circuit
cut-off system.
The engine can be started under the following
conditions.
a. When the transmission is in neutral. At this
time the neutral indicator light should come
on. If the light does not come on, ask a
Yamaha dealer to inspect it.
b. When the transmission is in gear and the
rear brake lever is applied. However, it is
recommended to shift into neutral before
starting the engine.
5. Use the choke lever in reference to the fig-
ure:
Position 1: Cold engine start-
ambient temperature below 30°C.
Position 2: Warming up position.
Position 3: Cold engine start-
ambient temperature above 25°C
and warm engine start position.

To decelerate:
When slowing down or stopping, release the
throttle and apply the brakes smoothly and
evenly. As you slow down, shift to a lower gear.
Be sure that the engine has sufficiently slowed
before engaging a lower gear. Improper use of
the brakes or shifting can cause the tires to lose
traction, reducing control and increasing the
possibility of an accident.
w
Make sure the engine has sufficiently slowed
before shifting to a lower gear. Engaging a
lower gear when the engine speed is too
high could make the wheels stop rotating.
This could cause loss of control, an accident
and injury. It could also cause engine or
drive train damage.

Parking on a slope
w
Avoid parking on hills or other inclines.
Parking on a hill or other incline could cause
the ATV to roll out of control, increasing the
chance of an accident. If you must park on
an incline, put the machine in low gear, apply
the parking brake, and block the front and
rear wheels with rocks or other objects.
Do not park the ATV at all on hills that are so
steep you could not walk up them easily.
1. Bring the machine to a stop by applying
the brakes in low gear.
2. Stop the engine.
3. With the rear brake lever and pedal
applied, apply the parking brake and slowly
release the rear brake pedal.

Select a large, flat area off-road to become
familiar with your ATV. Make sure that this area
is free of obstacles and other riders. You should
practice control of the throttle, brakes, shifting
procedures, and turning techniques in this area
before trying more difficult terrain. Always avoid
riding on paved surfaces: the ATV is designed
for off-road use only, and handling maneuvers
are more difficult to perform on pavement.
Set the parking brake and follow the instruction
on page 6-3 to start the engine. Once it has
warmed up you are ready to begin riding your
ATV. As you get on the ATV, be sure not to
accidentally move the shift pedal. Remember
that the engine and exhaust pipe will be hot
when riding and afterwards; do not allow skin or
clothing to come in contact with these compo-
nents.

With the engine idling, lift the shift pedal to the
1st gear position and then release the parking
brake. Apply the throttle slowly and smoothly.
The centrifugal clutch will engage and you will
start to accelerate. Once the ATV has attained
adequate speed, release the throttle and lift the
shift pedal to the 2nd gear position. Release the
shift pedal and apply the throttle smoothly. Use
this same procedure as you move into the high-
er gears. Be sure to coordinate the use of the
throttle and shift pedal properly. If the throttle is
applied too abruptly or if the throttle is not
released during shifting, or if the shift pedal is
not released before applying the throttle, the
front wheels may lift off the ground resulting in a
loss of directional control. Avoid higher speeds
until you are thoroughly familiar with the opera-
tion of your ATV.

Do not shift gears without releasing the
throttle. Damage to the engine or drive train
may occur.
When slowing down or stopping, release the
throttle and apply the brakes smoothly and
evenly. As you slow down, shift to a lower gear.
Be sure that the engine has sufficiently slowed
before engaging a lower gear. Improper use of
the brakes or shifting can cause the tires to lose
traction, reducing control and increasing the
possibility of an accident.
w
Make sure the engine has sufficiently slowed
before shifting to a lower gear. Engaging a
lower gear when the engine speed is too
high could cause the wheels to stop rotating.

If your ATV has stalled or stopped and you
believe you can continue up the hill, restart care-
fully to make sure you do not lift the front wheels
which could cause you to lose control. If you are
unable to continue up the hill, dismount the ATV
on the uphill side. Physically turn the ATV
around and then descend the hill.
If you start to roll backwards, DO NOT use the
rear brake to stop or try to put the ATV in gear.
The ATV could easily tip over backwards.
Instead, dismount the ATV immediately on the
uphill side.
