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.

cC
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.

Use proper gear and maintain steady speed
when climbing a hill.
If you lose all forward speed:
8Keep weight uphill.
8Apply the brakes.
8Lock parking brake, after you are stopped.
If you begin rolling backwards:
8Keep weight uphill.
8Never apply the rear brake while rolling
backwards. Apply the front brake.
When fully stopped, apply rear brake as
well, and then lock parking brake.
Dismount on uphill side or to a side if point-
ed straight uphill. Turn the ATV around and
remount, following the procedure described
in the Owner’s Manual.

CROSSING THROUGH SHALLOW WATER
The ATV can be used to cross slow moving,
shallow water of up to a maximum of 20 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.
w
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, 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.
cC
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. Wash the ATV in fresh water if it has
been operated in salt water or muddy condi-
tions.

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, positioning
your weight over the front wheels will sometimes
help.
If the rear wheels of your ATV start to slide side-
ways, control can usually be regained (if there is
room to do so) by steering in the direction of the
slide. Applying the brakes or accelerating is not
recommended until you have corrected the
slide.
