SAFETY INFORMATION
SAFETY INFORMATION
EBU26661
AN ATV IS NOT A TOY AND CAN BE HAZARDOUS TO OPERATE.
An ATV handles differently from other vehicles, including motorcycles and cars. A collision or rollover can occur quickly, even during routine
maneuvers such as turning and riding on hills or
over obstacles, if you fail to take proper precautions.
SEVERE INJURY OR DEATH can result if you do
not follow these instructions:
● Read this manual and all labels carefully and follow the operating procedures described.
● Never operate an ATV without proper training or
instruction. Take a Training Course. Beginners
should receive training from a certified instructor. Contact an authorized ATV dealer or call 1800-887-2887 to find out about the training
courses nearest you.
● Always follow the age recommendation:

1-1
– A child under 16 years old should never operate an ATV with engine size greater than 90 cc.
Never allow a child under age 16 to operate an
ATV without adult supervision, and never allow
continued use of an ATV by a child if he or she
does not have the abilities to operate it safely.
Never carry a passenger on an ATV.
Always avoid operating an ATV on any paved
surfaces, including sidewalks, driveways, parking lots and streets.
Never operate an ATV on any public street, road
or highway, even a dirt or gravel one.
Never operate an ATV without wearing an approved motorcycle helmet that fits properly. You
should also wear eye protection (goggles or face
shield), gloves, boots, a long-sleeved shirt or a
jacket, and long pants.
Never consume alcohol or drugs before or while
operating this ATV.
Never operate at speeds too fast for your skills
or the riding conditions. Always go at a speed

that is proper for the terrain, visibility, operating
conditions, and your experience.
Never attempt wheelies, jumps, or other stunts.
Always inspect your ATV each time you use it to
make sure it is in safe operating condition. Always follow the inspection and maintenance
procedures and schedules described in this
manual.
Always keep both hands on the handlebars and
both feet on the footboards of the ATV during
operation.
Always go slowly and be extra careful when operating on unfamiliar terrain. Always be alert to
changing terrain conditions when operating the
ATV.
Never operate on excessively rough, slippery or
loose terrain until you have learned and practiced the skills necessary to control the ATV on
such terrain. Always be especially cautious on
these kinds of terrain.
Always follow proper procedures for turning as
described in this manual. Practice turning at low
speeds before attempting to turn at faster
speeds and never turn at excessive speeds.
Never operate the ATV on hills too steep for the
ATV or for your abilities. Practice on smaller hills

before attempting larger hills.
Always follow proper procedures for climbing
hills as described in this manual. Check the terrain carefully before you start up any hill. Never
climb hills with excessively slippery or loose surfaces. Shift your weight forward. Never open the
throttle suddenly or make sudden gear changes.
Never go over the top of a hill at high speed.
Always follow proper procedures for going down
hills and for braking on hills as described in this
manual. Check the terrain carefully before you
start down any hill. Shift your weight backward.
Never go down a hill at high speed. Avoid going
down a hill at an angle that would cause the vehicle to lean sharply to one side. Go straight
down the hill where possible.
Always follow proper procedures for crossing
the side of a hill as described in this manual.
Avoid hills with excessively slippery or loose surfaces. Shift your weight to the uphill side of the
ATV. Never attempt to turn the ATV around on
any hill until you have mastered the turning technique described in this manual on level ground.
Avoid crossing the side of a steep hill if possible.
Always use proper procedures if you stall or roll
backwards when climbing a hill. To avoid stall-
●
●

ing, use the proper gear and maintain a steady
speed when climbing a hill. If you stall or roll
backwards, follow the special procedure for
braking described in this manual. Dismount on
the uphill side or to a side if pointed straight uphill. Turn the ATV around and remount, following
the procedure described in this manual.
Always check for obstacles before operating in a
new area.
Never attempt to operate over large obstacles,
such as large rocks or fallen trees. Always follow
proper procedures when operating over obstacles as described in this manual.
Always be careful when skidding or sliding.
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.
Never operate an ATV in fast flowing water or in
water deeper than that recommended in this
manual. Remember that wet brakes may have
reduced stopping ability. Test your brakes after
leaving water. If necessary, apply them several
times to let friction dry out the linings.
Always be sure there are no obstacles or people
behind you when you operate in reverse. When
it is safe to proceed in reverse, go slowly.
● Always use the size and type of tires specified in
this manual.
● Always maintain proper tire pressure as described in this manual.
● Never modify an ATV through improper installation or use of accessories.
● Never exceed the stated load capacity for an
ATV. Cargo should be properly distributed and
securely attached. Reduce speed and follow instructions in this manual for carrying cargo or
pulling a trailer. Allow greater distance for braking.

The ATV could start moving unexpectedly if
the parking brake is not applied before starting the engine. This could cause loss of control or a collision.
The brake could overheat if you ride the ATV
without releasing the parking brake. You
could lose braking performance which could
cause an accident. You could also wear out
the brakes prematurely.
HOW TO AVOID THE HAZARD
Always set the parking brake before starting
the engine.
Always be sure you have released the parking brake before you begin to ride.

ECB00070
CAUTION:
Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
4-10
rings, as well as to the exhaust system.
WHAT CAN HAPPEN
Fuel can spill, which can cause a fire and severe injury.
Fuel expands when it heats up. If the fuel
tank is overfilled, fuel could spill out due to
heat from the engine or the sun.
HOW TO AVOID THE HAZARD
Do not overfill the fuel tank. Be careful not to
spill fuel, especially on the engine or exhaust
pipe. Wipe up any spilled fuel immediately.
Be sure the fuel tank cap is closed securely.
Do not refuel right after the engine has been
running and is still very hot.
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.

EBU20920
Accessories
Accessories can affect the handling and control of
your ATV. Keep the following in mind when consid6-7
ering an accessory or operating an ATV which has
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 nonYamaha 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.
EBU20930
Loading
As originally equipped, this ATV is not designed to
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
the following points in mind:
● Never exceed the weight limits shown. An overloaded ATV can be unstable.

Ride 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 not to exceed 2nd gear whenever you
are carrying heavier loads or when towing a trailer.
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.
HOW TO AVOID THE HAZARD
Never exceed the stated load capacity for

release the clutch. Use this same procedure 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, resulting in a
loss of directional control. Avoid higher speeds until you are thoroughly familiar with the operation of
your ATV.
WHAT CAN HAPPEN
The ATV could wheelie. This would increase
the chance of an accident, including overturn.
HOW TO AVOID THE HAZARD

WARNING
WARNING
POTENTIAL HAZARD
Opening the throttle abruptly or releasing the
clutch lever too quickly.
POTENTIAL HAZARD
Engaging a lower gear when the engine
speed is too high.
7-16
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.
WHAT CAN HAPPEN
The wheels could stop rotating. This could
cause loss of control, an accident and injury.
It could also cause engine or drive train damage.
HOW TO AVOID THE HAZARD
Make sure the engine has sufficiently slowed
before shifting to a lower gear.
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.
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
low speed.

be able to perform it at higher speeds or in tighter
curves.
Improper riding procedures such as abrupt throttle
changes, excessive braking, incorrect body movements, 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 outside of the turn to avoid tipping over.
Remember: Avoid higher speeds until you are
thoroughly familiar with the operation of your ATV.

CLIMBING UPHILL
Use proper riding techniques to avoid ATV overturns on hills. Be sure that you can maneuver your
ATV well on flat ground before attempting any incline and then practice riding first on gentle slopes.
Try more difficult climbs only after you have developed your skill. In all cases avoid inclines with slippery or loose surfaces, or obstacles that might
cause you to lose control.

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.

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.
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.

POTENTIAL HAZARD
Stalling, rolling backwards or improperly dismounting while climbing a hill.
WHAT CAN HAPPEN
Could result in the ATV overturning.
HOW TO AVOID THE HAZARD
Use the proper gear and maintain a steady
speed when climbing a hill.
If you lose all forward speed:
● Keep weight uphill.
● Apply the brakes.
● Lock the parking brake after you are
stopped.
If you begin rolling backwards:
● Keep weight uphill.
● Never apply the rear brake while rolling
backwards. Apply the front brake.
● When fully stopped, apply the rear brake
as well, and then lock the parking brake.
Dismount on uphill side or to a side if pointed
straight uphill. Turn the ATV around and remount, following the procedure described in
the Owner’s Manual.
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 uphill side. Physically turn the ATV around and then
descend the hill.
If you start to roll backwards, DO NOT apply the
rear brake to stop or try to put the ATV in gear. The
ATV could easily tip over backwards. Instead, apply the front brake gradually, or dismount the ATV

SLIDING AND SKIDDING
Care should be used when riding on loose or slippery surfaces since the ATV may slide. If unexpected and uncorrected, sliding could lead to an
accident.
To reduce the tendency for the front wheels to slide
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.

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.
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 7-17.)
● 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
to the outside of the turn. (See page 7-17.)
● If your ATV starts to slide sideways:

If your ATV can’t make it up a hill you are trying
to climb:
Turn the ATV around if you still have forward
speed. If not, stop, dismount on the uphill side of
the ATV and physically turn the ATV around. If
the ATV starts to slip backwards, DO NOT USE
THE REAR BRAKE – the ATV may tip over on
top of you. Dismount the ATV on the uphill side.
(See page 7-18.)
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 7-18.)
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 7-24.)

Troubleshooting
Although Yamaha ATVs receive a thorough inspection before shipment from the factory, trouble
may occur during operation. Any problem in the fuel, compression, or ignition systems, for example,
can cause poor starting and loss of power.
The following troubleshooting charts represent
quick and easy procedures for checking these vital
systems yourself. However, should your ATV require any repair, take it to a Yamaha dealer, whose
skilled technicians have the necessary tools, experience, and know-how to service the ATV properly.
Use only genuine Yamaha replacement parts. Imitation parts may look like Yamaha parts, but they
are often inferior, have a shorter service life and
can lead to expensive repair bills.

Cleaning
Frequent, thorough cleaning of your ATV will not
only enhance its appearance but will improve its
general performance and extend the useful life of
many components.
1. Before cleaning the ATV:
a. Block off the end of the exhaust pipe to
prevent water entry. A plastic bag and
strong rubber band may be used.
b. Make sure the spark plug and all filler caps
are properly installed.
2. If the engine case is excessively greasy, apply
degreaser with a paint brush. Do not apply degreaser to the chain, sprockets or wheel axles.
3. Rinse the dirt and degreaser off with a garden
hose. Use only enough pressure to do the job.
4. Once most of the dirt has been hosed off,
wash all surfaces with warm water and mild,
detergent-type soap. An old toothbrush or bottle brush is handy for hard-to-reach places.
5. Rinse the ATV off immediately with clean water and dry all surfaces with a chamois, clean
towel or soft absorbing cloth.
6. Dry the chain and lubricate it to prevent it from
rusting.
7. Clean the seat with a vinyl upholstery cleaner
to keep the cover pliable and glossy.
8. Automotive type wax may be applied to all
painted and chrome plated surfaces. Avoid
combination cleaner-waxes. Many contain
abrasives which may mar the paint or protective finish. When finished cleaning, start the
engine and let it idle for several minutes.

POTENTIAL HAZARD
Operation with wet brakes after washing.
WHAT CAN HAPPEN
Wet brakes may have reduced stopping ability, increasing the chance of an accident.
HOW TO AVOID THE HAZARD
Test the brakes after washing. Apply the
brakes several times at slow speeds to let
friction dry out the linings.
Long-term
Before storing your ATV for several months:
1. Follow all the instructions in the “Cleaning”
section of this chapter.
2. Turn the fuel cock lever to “OFF”.
3. Drain the carburetor float chamber by loosening the drain bolt; this will prevent fuel deposits
from building up. Pour the drained fuel into the
fuel tank.
4. Fill up the fuel tank and add fuel stabilizer (if
available) to prevent the fuel from deteriorating.

all of its wheels are off the ground. Alternatively, turn the wheels a little every month in order
to prevent the tires from becoming degraded
in one spot.
Cover the muffler outlet with a plastic bag to
prevent moisture from entering it.
Remove the battery and fully charge it. Store
it in a cool, dry place and charge it once a
month. Do not store the battery in an excessively cold or warm place [less than 0 °C (30

THE PERIOD OF WARRANTY for Yamaha ATVs
shall be six (6) months from the date of purchase.
DURING THE PERIOD OF WARRANTY any authorized
Yamaha ATV dealer will, free of charge, repair or
replace any part adjudged defective by Yamaha due

Parts used in warranty repairs will be warranted for

EMISSION CONTROL SYSTEM WARRANTY
Yamaha Motor Corporation, USA also warrants to

ATV covered by this warranty that the vehicle is

CUSTOMER SERVICE
Q. What costs are my responsibility during the warranty period?
A. The customer’s responsibility includes all costs of normal maintenance services,
non-warranty repairs, accident and collision damages, and oil, oil filters, air filters,
spark plugs, and brake shoes.
If your machine requires warranty service, you must take it to any authorized
Yamaha ATV dealer within the continental United States. Be sure to bring
your warranty registration card or other valid proof of the original date of
purchase. If a question or problem arises regarding warranty, first contact
the owner of the dealership. Since all warranty matters are handled at the
dealer level, this person is in the best position to help you. If you are still
not satisfied and require additional assistance, please write:
Q. What are some examples of “abnormal” strain, neglect, or abuse?
A. These terms are general and overlap each other in areas. Specific examples include:
Running the machine out of oil, sustained high rpm, full-throttle, operating the
machine with a broken or damaged part which causes another part to fail, damage
or failure due to improper or careless transportation and or tie-down. If you have
any specific questions on operation or maintenance, please contact your dealer
for advice.
YAMAHA MOTOR CORPORATION U.S.A.
CUSTOMER RELATIONS DEPARTMENT
P.O. Box 6555
Cypress, California 90630
When contacting Yamaha Motor Corporation, U.S.A. don’t forget to include
any important information such as names, addresses, model, V.I.N. (frame
number), dates, and receipts.
Q. Does the warranty cover incidental costs such as towing or transportation due to
a failure?
A. No. The warranty is limited to repair of the machine itself.
CHANGE OF ADDRESS
Q. May I perform any or all of the recommended maintenance shown in the Owner’s
Manual instead of having the dealer do them?
A. Yes, if you are a qualified mechanic and follow the procedures specified in the Owner’s
and Service Manual. We do recommend, however, that items requiring
special tools or equipment be done by a Yamaha ATV dealer.
The federal government requires each manufacturer of a motor vehicle to
maintain a complete, up-to-date list of all first purchasers against the
possibility of a safety-related defect and recall. This list is compiled from
the purchase registrations sent to Yamaha Motor Corporation, U.S.A. by the
selling dealer at the time of your purchase.
Q. Will the warranty be void or cancelled if I do not operate or maintain my new ATV
exactly as specified in the Owner’s Manual?
A. No. The warranty on a new ATV cannot be “voided” or “cancelled.” However,
if a particular failure is caused by operation or maintenance other than as described
in the Owner’s Manual, that failure may not be covered under warranty.
If you should move after you have purchased your new ATV, please advise
us of your new address by sending a postcard listing your ATV model
name, V.I.N. (frame number), dealer number (or dealer’s name) as it is
shown on your warranty card, your name and new mailing address. Mail to:
Q. What responsibility does my dealer have under this warranty?
A. Each Yamaha ATV dealer is expected to:
1. Completely set up every new machine before sale.
2. Explain the operation, maintenance, and warranty requirements to your satisfaction at the time of sale, and upon your request at any later date.
3. Each Yamaha ATV dealer is held responsible for his setup, service and warranty repair work.
YAMAHA MOTOR CORPORATION, U.S.A.
P.O. Box 6555
Cypress, California 90630
Attention: Warranty Department
This will ensure that Yamaha Motor Corporation, U.S.A. has an up-to-date
registration record in accordance with federal law.
Q. Is the warranty transferable to second owners?
A. Yes. The remainder of the existing warranty can be transferred upon request. The
unit has to be inspected and re-registered by an authorized Yamaha ATV dealer
for the policy to remain effective.

YAMAHA EXTENDED SERVICE (Y.E.S.)

In addition, Travel and Recreation Interruption Protection
(TRIP) is included at no extra cost. TRIP gives you up to
$150 reimbursement per occurrence for any reasonable
expenses you incur because your Yamaha needs
covered service: replacement vehicle rental, emergency
towing, phone calls, even food and lodging when you are
away from home. This superb coverage goes into effect
when you purchase Y.E.S., so it applies to any warranty
repairs as well as covered repairs during your entire
Y.E.S. plan period.
Keep your Yamaha protected even after your warranty
expires with genuine Yamaha Extended Ser vice (Y.E.S.).
Y.E.S. is designed and administered by Yamaha Motor
Corporation to provide maximum owner satisfaction. You
get uninterrupted factor y-backed coverage for extra
peace of mind.
Y. E. S. is flexible. You choose the plan that’s right for
you: 12 months, 24 months, or 36 months beyond your
warranty period.
Y.E.S. coverage is honored at any authorized Yamaha
dealer nationwide.
Y.E.S. is designed and administered by the same
Yamaha people who handle your warranty – and it
shows in the comprehensive coverage benefits. There
are no mileage limitations. Coverage isn’t limited to
“moving par ts” or the “drive train” like many other plans.
And Y.E.S. covers manufacturing defects just like the
warranty. See the sample contract at your Yamaha
dealer to see how comfor ting uninterr upted factor ybacked protection can be.
Y.E.S. coverage is transferable to a new owner if you
sell or trade in your ATV. That can make your Yamaha
much more valuable!
This excellent Y.E.S. plan coverage is only available to
Yamaha owners like you, and only while your Yamaha is still
within the Yamaha Limited Warranty period. So visit your
authorized Yamaha dealer to get all the facts. He can show
you how easy it is to protect your investment with Yamaha
Extended Service.
You don’t have to pay anything for covered repairs.
T h e r e ’s n o d e d u c t i b l e t o p ay, a n d r e p a i r s a r e n ’ t
“pro-rated.” You don’t have any “out-of-pocket” expenses
for covered repairs.

buy your Yamaha. See your dealer today!
A special note:
If visiting your dealer isn’t convenient, contact Yamaha with
your Primar y ID number (your frame number). We’ll be
happy to help you get the Y.E.S. coverage you need.
