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 lever and pedal applied,
apply the parking brake, and then slowly re-
lease the 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, and turning tech-
niques in this area before trying more difficult ter-
rain. Always avoid riding on paved surfaces: the
ATV is designed for off-road use only, and han-
dling maneuvers are more difficult to perform on
pavement.
Set the parking brake and follow the instructions
on page 6-3 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, return the starter (choke) to
the closed position, shift the drive select lever into
the forward position, and 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 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.

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, 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 downhill
side. Avoid sudden application of either 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 immediate-
ly on the uphill side.

WARNING
_ Maintain steady speed when climbing a hill.
If you lose all forward speed:

Keep weight uphill.


Apply the brakes.


Apply the parking brake after you are
stopped.
If you begin rolling backwards:


Keep weight uphill.


2WD: Never apply the rear brake while roll-
ing backwards. Apply the front brake.
When fully stopped, apply the rear brake
as well, and then lock the parking brake.
4WD: Apply both front and rear brakes
gradually. When fully stopped, lock the
parking brake.
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, change to 4WD before be-
ginning 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 surfaces. 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 descending
hills, using either brake lever or the brake pedal
will brake the wheels on the downhill 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, 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, the V-belt
cooling duct check hose and the drive select
lever box check hose. Also, remove the V-belt
case drain plug to drain any water that may
have accumulated. Wash the ATV in fresh wa-
ter if it has been operated in salt water or mud-
dy conditions. _
