Parking on a slope
w
Avoid parking on hills or other inclines.
Parking 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, put the machine in low gear, 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 easily.
1. Bring the machine to a stop by applying
the front brake.
2. With the front and rear brake applied, pull
the clutch lever, shift into the neutral posi-
tion, and then apply the parking brake.
3. Stop the engine by setting the engine stop
switch to “OFF”.

Select a large, flat, unpaved area 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 use on unpaved surfaces 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, pull the clutch lever to
disengage the clutch and shift into 1st gear, and
then release the parking brake. Open the throttle
gradually, and at the same time, release the
clutch lever slowly. Once the ATV has attained
adequate speed, release the throttle lever and at
the same time, quickly pull in the clutch lever
and shift into 2nd gear. Open the throttle part
way and gradually release the clutch. Use this
same procedure as you move into the higher
gears. Be sure to coordinate the use of the throt-
tle 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.
w
Always open the throttle gradually and
release the clutch lever slowly. Otherwise,
the ATV could wheelie which would increase
the chance of an accident.

Use proper gear and maintain steady speed
when climbing a hill.
If you lose all forward speed:
8Keep weight uphill.
8Apply the brakes.
8Lock the 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 the rear brake
as well, and then lock the 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.

brake caliper by hand until it feels tight,
then screw it out 1/8 turn. Tighten the lock-
nut to the specified torque.

ing bolt with a wrench so that the adjusting
bolt does not turn together with the locknut.

Operating with improperly adjusted brakes
could cause the brakes to malfunction, result-
ing in reduced braking performance. This
could increase the chance of a collision or
accident. After adjusting the parking brake,
block the rear of the machine off the ground
and spin the rear wheels. Check to make sure
there is no brake drag. If brake drag is noticed,
perform the adjustment again.
Tightening torque:
Locknut:
16 Nm (1.6 m0kgf)
