in skills, physical abilities and judgment. Some children may not be able to operate an ATV safely. Parents
should supervise their child’s use of the ATV at all times. Parents should permit continued use only if they
determine that the child has the ability to operate the ATV safely.
Your ATV was delivered with an adjustable speed limiter. Yamaha recommends that all beginners start off
with the speed limiter screw turned in to limit the amount of speed available while they learn. The speed
limiter screw may be gradually turned out to increase maximum speed as the beginner becomes more familiar with operating the ATV.
If your child is a beginner or is inexperienced, he or she should take a training course. See the previous
page for information about the free training available to purchasers of new ATVs.

TEACHING YOUR CHILD TO OPERATE THE
ATV
EWB00040
WARNING
POTENTIAL HAZARD
Allowing a child under 16 to operate this ATV
without adult supervision (a child under 6
should not ride this ATV even with adult supervision).
WHAT CAN HAPPEN
If the child rides beyond his or her abilities,
or rides in terrain that is too difficult, he or
she may lose control of the ATV, causing an
accident.
HOW TO AVOID THE HAZARD
Never let your child ride an ATV without
close adult supervision. Promptly correct
your child if he or she begins to ride beyond
his or her abilities and, if necessary, intervene by pulling the cord (lanyard) to stop the
engine.
Introduce new riding areas slowly and make
sure the riding area matches your child’s
skill level.
You must make the commitment to your child’s
proper use of the ATV. Your child must rely upon
you to be sure he or she has the development,
proper training, and proper equipment, as well as
an appropriately sized ATV and an appropriate
riding area.
Be sure your child is ready to learn how to ride
As a parent, your first step is to decide when your
child has the strength, skills, and judgment to learn
how to operate an ATV safely. To help you make
that decision, the ATV Safety Institute publishes a
readiness checklist. It is printed in the Parents,
Youngsters and ATVs booklet that was included
with your ATV when newly purchased. You can
also review the checklist on the Internet at
www.atvsafety.org. Re-evaluate your child’s readiness before every use; a child who is too tired or
distracted should not be allowed to operate the
ATV.
Be sure your child is properly trained
Your child should take a certified training course,
like the ATV RiderCourse® offered by the ATV
Safety Institute. Call ATV Enrollment Express tollfree at 1-800-887-2887 for more information.
Training will continue with you as the instructor, so
you should be sure you thoroughly understand
proper riding techniques before continuing to in-

struct your child. Go through this Owner’s Manual
and the Parents, Youngsters and ATVs booklet
1
page by page with your child and be sure he or she
understands how to operate the ATV properly.
2
Be sure your child is wearing all the proper
3
safety equipment
Your child must always wear an approved motor-
4
cycle helmet that fits properly. Your child should
also wear the safety equipment described in the
5
Riding Your ATV section of this manual.
6
Choose an appropriate riding area
Select an area appropriate for your child to learn to
7
ride. (See page 7-11.) Follow the instructions in
the Riding Your ATV section of this manual.
8
Choose a large, flat off-road area that is free of obstacles and away from other vehicles.
9
Supervise every use of the ATV
10
Because an adult must supervise every ATV operator under age 16, you should closely watch your
11
child every time he or she uses the ATV. Be ready
to intervene immediately if the child is not operating according to your guidelines. This ATV is fitted
with an engine stop switch cord (lanyard) device
that will let you stop the engine remotely as you
walk behind the vehicle.
ENGINE STOP SWITCH CORD
This model has an engine stop switch cord (lanyard) designed for use by an adult supervising the
child operating the ATV. When using the engine
stop switch cord, be sure the speed limiter on the
handlebar is adjusted to limit the ATV to a walking
speed. (See page 4-5.)
1. Push the clip on the end of the engine stop
switch cord under the engine shut-off switch
(black button).
2. Put your fingers in the loop at the other end of
the cord.
3. As your child is riding, walk behind the ATV,
closely watching his or her actions as well as
the path ahead.
4. If there is a potential hazard ahead or if your
child is not riding correctly, pull firmly on the
cord to stop the engine. Because the ATV will
continue to roll for some distance, allow extra
time and distance to pull the cord before a potentially hazardous situation might be encountered.
When your child has developed sufficient skill to no
longer need you to follow with the cord, the cord
can be stowed under the seat of the ATV. Howev-
1-5
Page 15
er, you must still closely supervise your child at all
times during ATV operation.
NOTE:
The ATV will not start without the clip in place. Be
sure to remove the cord and store it in a safe place
to prevent operation of the ATV when you are not
around to supervise.
EWB00021
WARNING
POTENTIAL HAZARD
Improper handling of gasoline.
WHAT CAN HAPPEN
Gasoline can catch fire and you could be
burned.
HOW TO AVOID THE HAZARD
Always turn off the engine when refueling.
Do not refuel right after the engine has been
running and is still very hot.
Do not spill gasoline on the engine or exhaust pipe/muffler when refueling.
Never refuel while smoking, or in the vicinity
of sparks, open flames, or other sources of
ignition such as the pilot lights of water heaters and clothes dryers.
When transporting the ATV in another vehicle, be sure it is kept upright and that the fuel
cock is in the “OFF” position. Otherwise, fuel
may leak out of the carburetor or fuel tank.
WHAT CAN HAPPEN
Gasoline is poisonous and can cause injuries.
HOW TO AVOID THE HAZARD
If you should swallow some gasoline or inhale a lot of gasoline vapor, or get some gasoline in your eyes, seek medical help
immediately. If gasoline spills on your skin,
wash with soap and water. If gasoline spills
on your clothing, change your clothes.

throttle position. Because the throttle is springloaded, the ATV will decelerate, and the engine will
return to an idle any time the hand is removed from
the throttle lever.

WARNING
POTENTIAL HAZARD
Malfunction of throttle.
WHAT CAN HAPPEN
The throttle could be hard to operate, making
it difficult to speed up or slow down when
you need to. This could cause an accident.
HOW TO AVOID THE HAZARD
Check the operation of the throttle lever before you start the engine. If it does not work
smoothly, check for the cause. Correct the
problem before riding the ATV. Consult a
Yamaha dealer if you can’t find or solve the
problem yourself.

CAUTION:
Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
Your Yamaha engine has been designed to use
regular unleaded gasoline with a pump octane
number [(R+M)/2] of 86 or higher, or a research octane number of 91 or higher. If knocking or pinging
occurs, use a different brand of gasoline or premium unleaded fuel. Unleaded fuel will give you longer spark plug life and reduced maintenance cost.
Gasohol
There are two types of gasohol: gasohol containing ethanol and that containing methanol. Gasohol
containing ethanol can be used if the ethanol content does not exceed 10%. Gasohol containing
methanol is not recommended by Yamaha because it can cause damage to the fuel system or
ATV performance problems.

Engine break-in
There is never a more important period in the life of
3
your engine than the first 20 hours of riding. For
this reason, you should read the following material
4
carefully.
Since the engine is brand new, do not put an ex-
5
cessive load on it for the first 20 hours. The various
parts in the engine wear and polish themselves to
6
the correct operating clearances. During this period, prolonged full-throttle operation or any condi-
7
tion that might result in engine overheating must
8
be avoided.
9
0–10 hours
Avoid prolonged operation above 1/2 throttle. Vary
10
the speed of the ATV regularly. Do not operate it at
one set throttle position.

Accessories
Accessories can affect the handling and control of
10
your ATV. Keep the following in mind when considering an accessory or operating an ATV which has
11
accessories.
●
Choose only accessories designed for your
ATV. Your Yamaha dealer has a variety of genuine Yamaha accessories. Other accessories
may also be available on the market. However,
it is not possible for Yamaha to test all non-
Yamaha accessories, nor control over their quality or suitability. Choose a genuine Yamaha accessory, or one that is equivalent in design and
quality.
●
Accessories should be rigidly and securely
mounted. An accessory which can shift position
or come off while you are riding could affect your
ability to control the ATV.
●
Do not mount an accessory where it could interfere with your ability to control the ATV. Examples include (but are not limited to) a heavy or
bulky object attached to the handlebars which
could make steering difficult, an accessory that
limits your ability to move around on the seat, or
one that limits your view.
●
Use extra caution when riding an ATV with accessories. The ATV may handle differently than
it does without accessories.

carry cargo or tow a trailer. If you choose to add accessories so that you can carry cargo or tow a trailer, you must use common sense and good
judgment as the stability and handling of an ATV
can be changed. When adding accessories, keep
6-7
Page 51
the following points in mind:
●
Never exceed the weight limits shown. An overloaded ATV can be unstable.
MAXIMUM LOADING LIMIT
ATV loading limit (total weight of rider, cargo,
accessories, and tongue):
40.0 kg (88 lb)
●
If you are carrying cargo and towing a trailer, include the tongue weight in the maximum ATV
load limit.
●
Load cargo on the carriers as close to the center
of the ATV as possible. Put cargo at the rear of
the front carrier, at the front of the rear carrier,
and center it.
●
Tie down cargo securely to the carriers. Make
sure cargo in the trailer cannot move around. A
shifting load can cause an accident.
●
Make sure the load does not interfere with controls or your ability to see where you are going.
●
Ride more slowly than you would without a load.
The more weight you carry, the slower you
should go.
●
Allow more braking distance. A heavier ATV
takes longer to stop.
●
Avoid making sharp turns unless at very slow
speeds.
●
Avoid hills and rough terrain. Choose terrain
carefully. Added weight affects the stability and
handling of the ATV.

Speed limiter
For riders less experienced with this model, the
throttle lever housing is equipped with a speed limiter. 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 decreases the maximum speed of the ATV. Turning
in the adjusting screw decreases top speed, and
turning it out increases top speed. (See page 4-5.)
Yamaha recommends that all beginning riders
start off with the speed limiter turned in to limit the

Select a large, flat area off-road to become familiar
with your ATV. Make sure that this area is free of
8
obstacles and other riders. You should practice
control of the throttle, brakes, and turning tech-
9
niques in this area before trying more difficult ter-
10
rain. Always avoid riding on paved surfaces: the
ATV is designed for off-road use only, and han-
11
dling maneuvers are more difficult to perform on
pavement.
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. 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 components.
With the engine idling, shift the transmission into
the drive position and then release the parking
brake. 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 throttle and apply the brakes smoothly and evenly. Improper use of the brakes can cause the tires to lose
traction, reducing control and increasing the possibility of an accident.
TURNING YOUR ATV
To achieve maximum traction while riding off-road,
the two rear wheels are mounted solidly on one
axle and 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 technique must be
used to allow the ATV to make turns quickly and
easily. It is essential that this skill be learned first at
7-15
Page 67
low speed.
EWB01220
WARNING
POTENTIAL HAZARD
Turning improperly.
WHAT CAN HAPPEN
The ATV could go out of control, causing a
collision or overturn.
HOW TO AVOID THE HAZARD
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.
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 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.
1
2
1. Lean towards inside of turn.
2. Support your weight on the outer footboard.
This procedure should be practiced at slow speed
many times in a large off-road area with no obstacles. 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 procedure 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
1
changes, excessive braking, incorrect body movements, or too much speed for the sharpness of the
2
turn may cause the ATV to tip. If the ATV begins to
tip over to the outside while negotiating a turn, lean
3
more to the inside. It may also be necessary to
gradually let off on the throttle and steer to the out-
4
side of the turn to avoid tipping over.
Remember: Avoid higher speeds until you are
5
thoroughly familiar with the operation of your ATV.

CLIMBING UPHILL
Use proper riding techniques to avoid ATV over-
7
turns on hills. Be sure that you can maneuver your
ATV well on flat ground before attempting any in-
8
cline and then practice riding first on gentle slopes.
Try more difficult climbs only after you have devel-
9
oped your skill. In all cases avoid inclines with slip-
10
pery or loose surfaces, or obstacles that might
cause you to lose control.
EWB01090
11
WARNING
POTENTIAL HAZARD
Operating on excessively steep hills.
WHAT CAN HAPPEN
The ATV can overturn more easily on extremely steep hills than on level surfaces or
small hills.
HOW TO AVOID THE HAZARD
Never operate the ATV on hills too steep for
the ATV or for your abilities. Practice on
smaller hills before attempting large hills.
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 footboards
and leaning forward over the handlebars.
EWB01180
WARNING
POTENTIAL HAZARD
Climbing hills improperly.
WHAT CAN HAPPEN
Could cause loss of control or cause the ATV

Never open the throttle suddenly. 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.
OK
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.

Traversing a sloping surface on your ATV requires
you to properly position your weight to maintain
proper balance. Be sure that you have learned the
basic riding skills on flat ground before attempting
to cross a sloping surface. Avoid slopes with slippery surfaces or rough terrain that may upset your
balance.
As you travel across a slope, lean your body in the
uphill direction. It may be necessary to correct the
steering when riding on loose surfaces by pointing
the front wheels slightly uphill. When riding on
7-21
Page 73
slopes, be sure not to make sharp turns either up
or down hill.
If your ATV does begin to tip over, gradually steer
in the downhill direction if there are no obstacles in
your path. As you regain proper balance, gradually
steer again in the direction you wish to travel.

damage to the ATV or could lead to an upset or accident. Be sure to keep your feet firmly mounted on
the footboards at all times. Avoid jumping the ATV
as loss of control and damage to the ATV may result.

WHAT CAN HAPPEN
Could cause loss of control or a collision.

Could cause the ATV to overturn.
HOW TO AVOID THE HAZARD
4
Before operating in a new area, check for obstacles.
5
Never attempt to ride over large obstacles,
such as large rocks or fallen trees. When you
6
go over obstacles, always follow proper procedures as described in the Owner’s Manual.

SLIDING AND SKIDDING
Care should be used when riding on loose or slip-
9
pery surfaces since the ATV may slide. If unexpected and uncorrected, sliding could lead to an
10
accident.
To reduce the tendency for the front wheels to slide
11
in loose or slippery conditions, positioning your
weight over the front wheels will sometimes help.
If the rear wheels of your ATV start to slide sideways, control can usually be regained (if there is
room to do so) by steering in the direction of the
slide. Applying the brakes or accelerating is not
recommended until you have corrected the slide.
7-25
Page 77
WHAT CAN HAPPEN
You may lose control of this ATV. You may
also regain traction unexpectedly, which
may cause the ATV to overturn.
HOW TO AVOID THE HAZARD
Learn to safely control skidding or sliding by
practicing at low speeds and on level,
smooth terrain.
On extremely slippery surfaces, such as ice,
go slowly and be very cautious in order to reduce the chance of skidding or sliding out of
control.

With practice, over a period of time, skill at controlled sliding can be developed. The terrain
should be chosen carefully before attempting such
maneuvers, since both stability and control are reduced. Bear in mind that sliding maneuvers should
always be avoided on extremely slippery surfaces
such as ice, since all control may be lost.

Skidding or sliding improperly.
WHAT TO DO IF...
This section is designed to be a reference guide
only. Be sure to read each section on riding techniques completely.
WHAT TO DO...
●
If your ATV doesn’t turn when you want it to:
Bring the ATV to a stop and practice the turning
maneuvers again. Be sure you are putting your
weight on the footboard to the outside of the
turn. Position your weight over the front wheels
for better control. (See page 7-15.)
●
If your ATV begins to tip while turning:

Lean more into the turn to regain balance. If necessary, gradually let off the throttle and/or steer
1
to the outside of the turn. (See page 7-15.)
●
If your ATV starts to slide sideways:
2
Steer in the direction of the slide if you have the
room. Applying the brakes or accelerating is not
3
recommended until you have corrected the
slide. (See page 7-25.)
4
●
If your ATV can’t make it up a hill you are trying
to climb:
5
Turn the ATV around if you still have forward
speed. If not, stop, dismount on the uphill side of
6
the ATV and physically turn the ATV around. If
the ATV starts to slip backwards, DO NOT USE
7
THE REAR BRAKE – the ATV may tip over on
top of you. Instead, apply the front brake or dis-
8
mount the ATV on the uphill side. (See
9
page 7-17.)
●
If your ATV is traversing a sloping surface:
Be sure to ride with your weight positioned towards the uphill side of the ATV to maintain
proper balance. If the ATV starts to tip, steer
down the hill (if there are no obstacles in your
way) to regain balance. If you discover that the
ATV is going to tip over, dismount on the uphill
side. (See page 7-17.)
●
If your ATV encounters shallow water:
Ride slowly and carefully through slow moving
water, watching for obstacles. Be sure to let water drain from the ATV and CHECK YOUR
BRAKES FOR PROPER OPERATION when
you come out of the water. Do not continue to
ride your ATV until you have regained adequate
braking ability. (See page 7-22.)

shoes
The front and rear brake shoes must be checked
for wear at the intervals specified in the periodic
maintenance and lubrication chart. Each brake is
provided with a wear indicator, which allows you to
check the brake shoe wear without having to disassemble the brake. To check the brake shoe
wear, check the position of the wear indicator while
applying the brake. If a brake shoe has worn to the
point that the wear indicator reaches the wear limit
line or mark, have a Yamaha dealer replace the
brake shoes as a set.
