To start out and accelerate:
1. Release the throttle lever.CAUTION:
Always close the throttle while shifting gears.
Otherwise, damage to the engine and drive
train may result. 2. Shift into first gear and release the shift ped-
al.
3. Open the throttle gradually.
4. Once the machine has attained adequate
speed, release the throttle lever.
5. Shift into second gear and release the shift
pedal.
6. Open the throttle gradually.
7. Follow the same procedure when shifting to
the next higher gear.

To decelerate:
When slowing down or stopping, release the throt-
tle 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 shift-
ing can cause the tires to lose traction, reducing
control and increasing the possibility of an acci-
dent.
WARNING
Make sure the engine has sufficiently slowed
before shifting to a lower gear. Engaging a low-
er gear when the engine speed is too high
could make the wheels stop rotating. This
could cause loss of control, an accident and
injury. It could also cause engine or drive train
damage.

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, put the ATV in low gear, apply the park-
ing 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 ATV to a stop by applying the
brakes in low gear.
2. Stop the engine.
3. With the rear brake lever and brake pedal ap-
plied, apply the parking brake and slowly re-
lease the brake pedal.

During operation
Always keep your feet on the footboards during
operation. Otherwise your feet may contact the
rear wheels.
WARNING
_ Always keep both hands on the handlebars
and both feet on the footboards of your ATV
during operation. Removing even one hand or
foot can reduce your ability to control the ATV
or could cause you to lose your balance and
fall off of the ATV. If you remove a foot from a
footboard, your foot or leg may come into con-
tact with the rear wheels, which could injure
you or cause an accident. _ Avoid wheelies and jumping. You may lose control
of the ATV or overturn.
WARNING
_ Never attempt stunts, such as wheelies or
jumps. Don’t try to show off. _

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 centrif-
ugal clutch will engage and you will start to accel-
erate. 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 proce-
dure as you move into the higher 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 re-
sulting in a loss of directional control. Avoid higher
speeds until you are thoroughly familiar with the
operation of your ATV.CAUTION:_ Do not shift gears without releasing the throt-
tle. Damage to the engine or drive train may oc-
cur. _
