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.

WARNING
Use proper gear and maintain steady speed
when climbing a hill.
If you lose all forward speed:l
Keep weight uphill.
l
Apply the brakes.
l
Shift into the parking position, after you
are stopped.
If you begin rolling backwards:
l
Keep weight uphill.
l
2WD: Never apply the rear brake while
rolling backwards. Apply the front brake.
4WD: Apply both front and rear brakes
gradually.
When fully stopped, shift into the parking
position.
Dismount on uphill side or to a side if pointed
straight uphill. Turn the ATV around and re-
mount, following the procedure described in
the Owner’s Manual.

RIDING DOWNHILL
When riding your ATV downhill, shift your
weight as far to the rear and uphill side of the
ATV as possible. Move back on the seat and sit
with your arms straight. Engine compression
will do most of the braking for you. For maxi-
mum engine compression braking effect, se-
lect low range and change to 4WD before
beginning to descend the hill. Improper brak-
ing may cause a loss of traction.
Use caution while descending a hill with loose
or slippery surfaces. Braking ability and trac-
tion may be adversely affected by these surfac-
es. Improper braking may also cause a loss of
traction.
When this ATV is in 4WD, all wheels (front and
rear) are interconnected by the drive train. This
means that applying either the front brake or
the rear brake will brake all wheels. When de-
scending hills, using either brake lever or the
brake pedal will brake the wheels on the down-
hill side. Avoid sudden application of either the
front or rear brake because the wheels on the
uphill side could come off the ground. Apply
both the front and rear brakes gradually.

CROSSING THROUGH SHALLOW WATER
The ATV can be used to cross slow moving,
shallow water of up to a maximum of 35 cm in
depth. Before entering the water, choose your
path carefully. Enter where there is no sharp
drop off, and avoid rocks or other obstacles
which may be slippery or upset the ATV. Drive
slowly and carefully.
WARNING
Never operate this ATV in fast flowing water
or in water deeper than that specified in your
Owner’s Manual. Remember that wet brakes
may have reduced stopping ability. Test your
brakes after leaving water. If necessary, apply
them several times to let friction dry out the
linings. If the ATV is operated through deep or
fast flowing water, the tires may float, causing
loss of traction and loss of control, whichcould lead to an accident.

EL
Test your brakes after leaving the water. Do
not continue to ride your ATV without verifying
that you have regained proper braking ability.CAUTION:After riding your ATV in water, be sure to
drain the trapped water by removing the
check hose at the bottom of the air filter case
and the check hose on the V-belt cooling duct.
Wash the ATV in fresh water if it has been op-erated in salt water or muddy conditions.

SLIDING AND SKIDDING
Care should be used when riding on loose or
slippery surfaces since the ATV may slide. If
unexpected and uncorrected, sliding could
lead to an accident.
To reduce the tendency for the front wheels to
slide in loose or slippery conditions, position-
ing your weight over the front wheels will
sometimes help.
If the rear wheels of your ATV start to slide
sideways, control can usually be regained (if
there is room to do so) by steering in the direc-
tion of the slide. Applying the brakes or accel-
erating is not recommended until you have
corrected the slide.

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.)
