or face shield), gloves, boots, a long-sleeved
shirt or jacket, and long pants.


Never consume alcohol or drugs before or

WARNING
_ Always ride at a slow speed when the ATV is in
4WD-LOCK, and allow extra time and distance
for maneuvers.
All wheels turn at the same speed when the dif-
ferential is locked, so it takes more effort to
turn the ATV. The amount of effort is more the
faster you go. You may lose control and have
an accident if you cannot make a sharp
enough turn for the speed you are traveling. _

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 easily. _1. Bring the machine to a stop by applying the
brakes.
2. Stop the engine.
3. With the brake pedal applied, shift the drive
select lever to the park position “P”.

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, 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. _
