Exhaust system
WARNING
EWB01501●Dry grass or brush or other combustible ma-
terial accumulated around the engine area
could catch fire. Do not operate, idle, or park
the ATV in dry grass or other dry ground cov-
er. Keep the engine area free of dry grass,
brush, or other combustible material.●Someone touching the exhaust system dur-
ing or after operation could be burned. Do
not touch the hot exhaust system. Do not
park the ATV in a place where others might
be likely to touch it.The muffler and other engine parts become ex-
tremely hot during operation and remain hot after
the engine has stopped. To reduce the risk of fire
during operation or after leaving the ATV, do not let
brush, grass and other materials collect under the
vehicle, near the muffler or exhaust pipe, or next to other hot parts. Check under the vehicle after op-
erating in areas where combustible materials may
have collected. Do not idle or park the vehicle in
long dry grass or other dry ground cover.
To prevent burns, avoid touching the exhaust sys-
tem. Park the ATV in a place where pedestrians or
children are not likely to touch it.U18P67E0.book Page 8 Wednesday, May 9, 2012 3:30 PM

7BE CAREFUL WHERE YOU RIDE
This ATV is designed for use on unpaved surfaces
only.
WARNING! Paved surfaces may seriously
affect handling and control of the ATV, and
may cause the ATV to go out of control. Always
avoid paved surfaces, including sidewalks,
driveways, parking lots and streets.
[EWB01511]
While riding on unpaved public streets or roads
may be legal in your area, such operation can in-
crease the risk of collision with other vehicles. Watch carefully for other vehicles. Make sure you
know your country’s laws and regulations before
you ride on unpaved public streets or roads. Do not
ride on any paved public street, road or motorway.
WARNING! Never operate this ATV on any paved street, paved road or motorway. You can
collide with another vehicle.
[EWB01521]
Know the terrain where you ride. Ride cautiously in
unfamiliar areas. Stay alert for holes, rocks, or
roots in the terrain, and other hidden hazards
which may cause the ATV to upset. WARNING!
The ATV could go out of control if you do not

have enough time to react to hidden rocks,
bumps, or holes. Go slowly and be extra care-
ful when operating on unfamiliar terrain. Al-
ways be alert to changing terrain conditions
when operating the ATV.
[EWB01531]
Do not operate on rough, slippery, or loose terrain
until you have learned and practiced the skills nec-
essary to control the ATV on such terrain. Always
be especially cautious on these kinds of terrain.
WARNING! Failure to use extra care when op- erating on excessively rough, slippery, or loose terrain could cause loss of traction or
ATV control, which could result in an accident,
including an overturn.
[EWB01541]
When riding in an area where you might not easily
be seen, such as desert terrain, mount a caution
flag on the ATV. DO NOT use the flag pole bracket
as a trailer hitch.
WARNING! You could collide
with another vehicle if operating in areas where
you cannot easily be seen. Mount a caution
flag on the ATV to make you more visible.
Watch carefully for other vehicles.

7Do not ride in areas posted “no trespassing”.
Do not ride on private property without getting per-
mission. Select a large, flat, unpaved area to become famil-
iar 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.
Set the parking brake and follow the instruction on
page 6-1 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. 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, re-
lease the clutch lever slowly. Once the ATV has at-
tained adequate speed, release the throttle lever
and at the same time, quickly pull in the clutch le-
ver and shift into 2nd gear. Open the throttle part
way and gradually release the clutch.
WARNING!
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 con-

trol.
[EWB02631]

NOTICE: Do not shift gears without
releasing the throttle. Damage to the engine or
drive train may occur.
[ECB01071]
Use this same procedure as you move into the
higher gears. Be sure to coordinate the use of the
throttle and shift pedal properly.
Avoid higher speeds until you are thoroughly famil-
iar with the operation of your ATV.
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 shifting
can cause the tires to lose traction, reducing con-
trol and increasing the possibility of an accident.
TURNING YOUR ATV
WARNING
EWB01771Always follow proper procedures for turning
as described in this Owner’s Manual. Practice
turning at low speeds before attempting to turn
at faster speeds. Do not turn at speeds too fast
for your skills or the conditions. ATV could go
out of control, causing a collision or overturn.
To achieve maximum traction on unpaved surfac-
es, the two rear wheels turn together at the same
speed. Therefore, unless the wheel on the inside
of the turn is allowed to slip or lose some traction,
the ATV will resist turning. A special turning tech-
nique must be used to allow the ATV to make turns
quickly and easily. It is essential that this skill be
learned first at low speed.
As you approach a curve, slow down and begin to
turn the handlebars in the desired direction. As you
do so, put your weight on the footrest to the outside
of the turn (opposite your desired direction) and
lean your upper body into the turn. Use the throttle
to maintain an even speed through the turn. This
maneuver will let the wheel on the inside of the turn
slip slightly, allowing the ATV to make the turn
properly.

7This procedure should be practiced at slow speed
many times in a large unpaved area with no obsta-
cles. If an incorrect technique is used, your ATV
may continue to go straight. If the ATV doesn’t
turn, come to a stop and then practice the proce-
dure again. If the riding surface is slippery or loose,
it may help to position more of your weight over the
front wheels by moving forward on the seat.
Once you have learned this technique, you should
be able to perform it at higher speeds or in tighter
curves. Improper riding procedures such as abrupt throttle
changes, excessive braking, incorrect body move-
ments, or too much speed for the sharpness of the
turn may cause the ATV to tip. If the ATV begins to
tip over to the outside while negotiating a turn, lean
more to the inside. It may also be necessary to
gradually let off on the throttle and steer to the out-
side of the turn to avoid tipping over.
Remember: Avoid higher speeds until you are
thoroughly familiar with the operation of your ATV.
CLIMBING UPHILL
WARNING
EWB01591Climbing hills improperly can cause overturns
or loss of control. Use proper riding tech-
niques described in this Owner’s Manual.●Never operate the ATV on hills too steep for
the ATV or for your abilities. The ATV can
overturn more easily on extremely steep hills
than on level surfaces or small hills.●Always check the terrain carefully before
you start up any hill. Never climb hills with
excessively slippery or loose surfaces.●Shift your weight forward.
1. Lean towards inside of turn.
2. Support your weight on the outer footrest.U18P67E0.book Page 13 Wednesday, May 9, 2012 3:30 PM

●Never open the throttle suddenly or make
sudden gear changes. The ATV could flip
over backwards.●Never go over the top of any hill at high
speed. An obstacle, a sharp drop, or another
vehicle or person could be on the other side
of the hill.●Never attempt to turn the ATV around on any
hill until you have mastered the turning tech-
nique as described in the Owner’s Manual on
level ground. Be very careful when turning
on any hill.●Avoid crossing the side of a steep hill if pos-
sible. When crossing the side of a hill, shift
your weight to the uphill side of the ATV.

7Do not attempt to climb hills until you have mas-
tered basic maneuvers on flat ground. Always
check the terrain carefully before attempting any
hill. In all cases avoid inclines with slippery or loose
surfaces, or obstacles that might cause you to lose
control.
To climb a hill, you need traction, momentum, and
steady throttle. Travel fast enough to maintain mo-
mentum, but not so fast that you cannot react to
changes in the terrain as you climb. It is important when climbing a hill to make sure
that your weight is transferred forward on the ATV.
This can be accomplished by leaning forward and,
on steeper inclines, standing on the footrests and
leaning forward over the handlebars. Whenever
possible, ride straight up hills.
Slow down when you reach the crest of the hill if
you cannot see clearly what is on the other side –
there could be another person, an obstacle, or a
sharp drop-off. Use common sense and remember
that some hills are too steep for you to climb or de-
scend.
If you are climbing a hill and you find that you have
not properly judged your ability to make it to the
top, you should turn the ATV around while you still
have forward motion (provided you have the room
to do so) and go down the hill.
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 up-
hill side. Physically turn the ATV around and then
descend the hill.
