Do not operate after or while consuming
alcohol or drugs.
The operator’s performance capability is reduced
by the influence of alcohol or drugs. Consuming al-
cohol or drugs could seriously affect your judg-
ment, cause you to react more slowly, and affect
your balance and perception.
WARNING! Never
consume alcohol or drugs before or while driv-
ing this ATV. You increase your chance of anaccident.
[EWB01421]
Pre-operation checks
Always inspect your ATV each time you use it to
make sure the ATV is in safe operating condition.
Perform the pre-operation checks listed on page
5-1. Always follow the inspection and maintenance
procedures and schedules described in the Own-
er’s Manual.
WARNING! Failure to inspect the
ATV before operating it and to maintain it prop-
erly increases the possibility of an accident or
equipment damage.

iter. The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed to
the maximum. Turning in the adjusting screw limits
the maximum engine power available and de-
creases the maximum speed of the ATV. Turning
in the adjusting screw decreases top speed, and
turning it out increases top speed. (See page 4-3.)
Loading and accessories
Take extra precautions when driving with a load or
trailer. Follow these instructions and always use
common sense and good judgment when carrying
cargo or towing a trailer.
WARNING

EWB01461
Improper loading or towing can increase the
risk of loss of control, an overturn, or other ac-
cident. To reduce the risk of an accident:

Do not exceed the maximum loading limits
for the vehicle (see box in this section or ve-
hicle labeling).

Keep weight on racks centered side to side,
and as low as possible. Be sure cargo is se-
cured – a loose load could change handling
unexpectedly.

Make sure the load does not interfere with
your control or ability to see where you are
going.

Tie down cargo in the trailer securely. Make
sure cargo in the trailer cannot move around.
A shifting load can cause an accident.

Reduce speed and allow more room to stop.
A heavier vehicle takes longer to stop.

Avoid hills and rough terrain. Choose terrain
carefully. Use extreme caution when towing
or carrying a load on inclines.

Turn gradually and go slowly.
Drive more slowly than you would without a load.
The more weight you carry, the slower you should
go. Although conditions vary, it is good practice to
drive slowly (shift into first gear or low drive if avail-
able on this model) whenever you are carrying
heavier loads or when towing a trailer.
During operation
Always keep your feet on the footboards during op-
eration; otherwise, they may contact the rear
wheels.
WARNING! 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 contact with the rear wheels, which couldinjure you or cause an accident.

[EWB01471]
Avoid wheelies and jumping.
WARNING! At-
tempting wheelies, jumps, and other stunts in-
creases the chance of an accident, including
an overturn. Never attempt stunts, such as
wheelies or jumps. Don’t try to show off.
[EWB01481]

[EWB01491]
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

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

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.

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. With the
engine idling, return the starter knob to the closed
position and shift the drive select lever into the for-
ward position, then release the parking brake. Ap-
ply 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 ina 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 possi-
bility of an accident.
TURNING YOUR ATV
WARNING

EWB01771
Always 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 footboard to the out-
side 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.
This procedure should be practiced at slow speedmany 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

EWB01671
Climbing hills improperly can cause overturns
or loss of control. Use proper riding tech-
niques described in this Owner’s Manual.
1. Lean towards inside of turn.
2. Support your weight on the outer footboard.
