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.
1. Apply the rear brake lever.
2. Turn the fuel cock to “ON”.
3. Turn the main switch to “ON” and the en-
gine stop switch to “ ”.
4. Shift the drive select lever into the neutral
or park position.

return the throttle lever to the closed posi-
tion.
b. Apply the rear brake pedal.
c. Shift from neutral to reverse or from re-
verse to park and vice versa by moving
the drive select lever along the shift guide.

With the engine idling, shift the drive select le-
ver into low or high. Then release the parking
brake. 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 con-
trol. Avoid higher speeds until you are thor-
oughly familiar with the operation of your ATV.
When slowing down or stopping, release the
throttle and apply the brakes smoothly and
evenly. Improper use of the brakes can cause
the tires to lose traction, reducing control and
increasing the possibility of an accident.CAUTION:Do not shift from low to high or vice versa
without coming to a complete stop. Damageto the engine or drive train may occur.

If your ATV has stalled or stopped and you be-
lieve 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, dis-
mount the ATV on the uphill side. Physically
turn the ATV around and then descend the hill.
If you start to roll backwards, DO NOT apply ei-
ther brake abruptly. If you are in 2WD, apply
only the front brake. When this ATV is in 4WD,
all wheels (front and rear) are interconnected
by the drive train. This means that applying ei-
ther the front brake or the rear brake will brake
all wheels. When descending hills, using either
brake lever or the brake pedal will brake the
wheels on the downhill side. Avoid sudden ap-
plication of either the front or rear brake be-
cause the wheels on the uphill side could come
off the ground. The ATV could easily tip over
backwards. Apply both the front and rear
brakes gradually, or dismount the ATV imme-
diately on the uphill side.

WHAT TO DO IF...
This section is designed to be a reference
guide only. Be sure to read each section on
riding techniques completely.
WHAT TO DO...l
If your ATV doesn’t turn when you want it
to:
Bring the ATV to a stop and practice the
turning maneuvers again. Be sure you are
putting your weight on the footboard to the
outside of the turn. Position your weight
over the front wheels for better control.
(See pages 7-39 ~ 7-43.)
l
If your ATV begins to tip while turning:
Lean more into the turn to regain balance. If
necessary, gradually let off the throttle
and/or steer to the outside of the turn. (See
pages 7-39 ~ 7-43.)
l
If your ATV starts to slide sideways:
Steer in the direction of the slide if you have
the room. Applying the brakes or accelerat-
ing is not recommended until you have cor-
rected the slide. (See pages 7-71 ~ 7-73.)

l
If your ATV can’t make it up a hill you are
trying to climb:
Turn the ATV around if you still have for-
ward speed. If not, stop, dismount on the
uphill side of the ATV and physically turn
the ATV around. If the ATV starts to slip
backwards DO NOT USE THE REAR BRAKE
- the ATV may tip over on top of you. Dis-
mount the ATV on the uphill side. (See
pages 7-45 ~ 7-53.)
l
If your ATV is traversing a sloping surface:
Be sure to ride with your weight positioned
towards the uphill side of the ATV to main-
tain proper balance. If the ATV starts to tip,
steer down the hill (if there are no obstacles
in your way) to regain balance. If you dis-
cover that the ATV is going to tip over, dis-
mount on the uphill side. (See pages 7-59 ~
7-61.)
