Parking on a slope
WARNING
Avoid parking on hills or other inclines. Park-
ing 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, place the machine transversely across
the incline, 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 easi-
ly.1. Bring the machine to a stop by applying the
brakes.
2. Stop the engine.
3. With the rear brake applied, shift the drive se-
lect lever to the park position.

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.
Shift to the parking position “P” and follow the in-
struction on page 6-1 to start the engine. Once it
has warmed up you are ready to begin riding your
ATV. Remember that the engine and exhaust pipe
will be hot when riding and afterwards; do not al-
low skin or clothing to come in contact with these
components.

With the engine idling, shift the drive select lever to
the low position “L” or the high position “H”. 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 until 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
possibility of an accident.CAUTION:_ Do not shift from drive position low “L” to high
“H” or vice versa without coming to a com-
plete stop. Damage to the engine or drive train
may occur. _

If your ATV has stalled or stopped and you believe
you can continue up the hill, restart carefully 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 apply either
brake abruptly. If you are in 2WD, apply only the
front brake. When this ATV is in 4WD or 4WD-
LOCK, all wheels (front and rear) are interconnect-
ed 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 application of ei-
ther the front or rear brake because 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 immediately on the uphill side.

WARNING
_ Use proper gear and maintain steady speed
when climbing a hill. If you lose all forward
speed:

Keep weight uphill.


Apply the brakes.


Shift into the park position “P” after you
are stopped.
If you begin rolling backwards:


Keep weight uphill.


2WD: Never apply the rear brake while
rolling backwards. Apply the front brake.
4WD or 4WD-LOCK: Apply both front and
rear brakes gradually.
When fully stopped, shift into the park po-
sition “P”.
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 pos-
sible. Move back on the seat and sit with your
arms straight. Engine compression will do most of
the braking for you. For maximum engine com-
pression braking effect, select low range “L” and
change to 4WD or 4WD-LOCK before beginning
to descend the hill. Improper braking may cause a
loss of traction. Use caution while descending a hill
with loose or slippery surfaces. Braking ability and
traction may be adversely affected by these sur-
faces. Improper braking may also cause a loss of
traction.
When this ATV is in 4WD or 4WD-LOCK, 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 descending 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 up-
hill 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, shal-
low water of up to a maximum of 35 cm in depth.
Before entering the water, choose your path care-
fully. Enter where there is no sharp drop off, and
avoid rocks or other obstacles which may be slip-
pery 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 lin-
ings. If the ATV is operated through deep or
fast flowing water, the tires may float, causing
loss of traction and loss of control, which
could lead to an accident. _

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 operated in
salt water or muddy conditions. _
