SAFETY INFORMATION

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.
ginners should receive training from a certified instructor. Contact an authorized ATV dealer
or call 1-800-887-2887 to find out about the training courses nearest you.

●

Always follow the age recommendation:

- A child under 16 years old should never operate an ATV with engine size greater than 90cc.

●

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 passenger on an ATV.

Take a Training Course.

Be-

2-1

●

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, long-sleeved
shirt or 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 conditions. Always go at a speed that
is proper for the terrain, visibility and 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.

●

●

Always follow proper procedures for turning as described in this manual. Practice turning at
low speeds before attempting to turn at faster speeds. Do not turn at excessive speed.

●

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.

2-3

●

Always use proper procedures if you stall or roll backwards when climbing a hill. To avoid
stalling, use 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.

2-4

●

Always use the size and type 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.

WARNI NG

POTENTIAL HAZARD
Changing from 2WD to 4WD or from
4WD to 2WD while the ATV is moving.
WHAT CAN HAPPEN
The ATV handles differently in 2WD
than in 4WD in some circumstances.
Changing from 2WD to 4WD or from
4WD to 2WD while moving may cause
the ATV to unexpectedly handle differ­ently. This could distract the operator
and increase the risk of losing control
and an accident.
HOW TO AVOID THE HAZARD
Always stop the ATV before changing

EBU00062

Throttle lever

Once the engine is running, movement of the
throttle lever will increase the engine speed.
Regulate the speed of the machine by varying
the throttle position. Because the throttle is
spring-loaded, the machine will decelerate,
and the engine will return to an idle any time
the hand is removed from the throttle lever.

1. Throttle lever

Before starting the engine, check the throttle
to be sure it is operating smoothly. Make sure
it returns to the idle position as soon as the le­ver is released.

WARNI NG

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.

Brake levers and brake pedal
Check for correct free play in the brake levers
and brake pedal. If the free play is incorrect,
adjust it. (See pages 8-24–8-27.)
Check operation of the levers and pedal. They
should move smoothly and there should be a
firm feeling when the brake is applied. If not,
have a Yamaha dealer inspect them.

Brake fluid level (front brake)
Check the brake fluid level. Add fluid if neces­sary. (See pages 8-22–8-23.)

Recommended brake fluid:DOT 4

Brake fluid leakage (front brake)
Check to see if any brake fluid is leaking out of
the hose, joint or brake fluid reservoir of the
front brake. Apply the brake firmly for one
minute. If the lever moves slowly inward,
there may be a leak in the brake system. If
there is any leakage, the brake system should
be inspected by a Yamaha dealer.

Total:

15 L (3.3 Imp gal, 4.4 US gal)

Reserve:

4.0 L (0.9 Imp gal, 1.1 US gal)

CAUTION:

_

Use only unleaded gasoline. The use of
leaded gasoline will cause severe damage
to internal engine parts, such as the valves
and piston rings, as well as to the exhaust
system.

_

Your Yamaha engine has been designed to
use regular unleaded gasoline with a pump
octane number ([R+M]/2) of 86 or higher, or
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
ethanol content does not exceed 10%. Gaso­hol containing methanol is not recommended
by Yamaha because it may cause fuel system
damage or vehicle performance problems.

EBU00209

Engine break-in

There is never a more important period in the
life of your machine than the period between
zero and 20 hours.
For this reason, we ask that you carefully read
the following material. Because the engine is
brand new, you must not put an excessive
load on it for the first several hours of running.
During the first 20 hours, the various parts in
the engine wear and polish themselves to the
correct operating clearances.
During this period, prolonged full throttle oper­ation or any condition which might result in ex­cessive engine heating must be avoided.
However, momentary (2–3 seconds maxi­mum) full throttle operation under load does
not harm the engine.

Each full throttle acceleration sequence
should be followed with a substantial rest pe­riod for the engine by cruising at lower r/min
so the engine can rid itself of the temporary
build up of heat.
If any abnormality is noticed during this peri­od, consult a Yamaha dealer.

1. 0–10 hours:
Avoid continuous operation above half
throttle. Allow a cooling off period of five
to ten minutes after every hour of opera­tion. Vary the speed of the machine from
time to time. Do not operate it at one set
throttle position.

6-7

2. 10–20 hours:
Avoid prolonged operation above
3/4 throttle. Rev the machine freely
through the gears but do not use full
throttle at any time.

3. After break-in:
Avoid prolonged full throttle operation.
Vary speeds occasionally.

HOW TO AVOID THE HAZARD
Avoid parking on hills or other inclines.
If you must park on an incline, put the
machine in low gear, 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 in low gear.

Accessories and loading

EBU00222

Accessories

Accessories can affect the handling and con­trol of your ATV. Keep the following in mind
when considering 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 non-Yamaha accesso­ries, nor have any control over the quality or
suitability of them. 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.

6-10

EBU00588

Loading

Cargo or a trailer can change the stability and
handling of an ATV.
You must use common sense and good judg­ment when carrying cargo or towing a trailer.
Keep the following points in mind:

●

Never exceed the weight limits shown. An
overloaded ATV can be unstable.

MAXIMUM LOADING LIMIT

●

Vehicle loading limit (total weight of
cargo, rider and accessories, and tongue
weight): 210 kg (463 lb)

●

Front carrier: 40 kg (88 lb)

●

Rear carrier: 80 kg (176 lb)

●

Storage box: 2 kg (4.4 lb)

●

Trailer hitch:
Pulling load (total weight of trailer and
cargo): 410 kgf (904 lbf)
Tongue weight (vertical weight on trailer
hitch point): 15 kgf (33 lbf)

●

Do not exceed the maximum tongue
weight. You can measure tongue weight
with a bathroom scale. Put the tongue of
the loaded trailer on the scale with the
tongue at hitch height. Adjust the load in the
trailer, if necessary, to reduce the weight on
hitch.

●

If you are carrying cargo and towing a trail­er, include the tongue weight in the maxi­mum vehicle load limit.

●

Load cargo on the carrier as close to the
center of the vehicle as possible. Put cargo
at the front of the rear carrier. Center the
load from side to side.

●

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.

6-11

●

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 ve­hicle 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.

kinds of terrain.

7-19

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.

WARNI NG

POTENTIAL HAZARD
Operating in areas where you might not
be seen by other off-road vehicles.

WHAT CAN HAPPEN
You could be in a collision. You could
be injured.
HOW TO AVOID THE HAZARD
Always mount a caution flag on the ATV
to make you more visible. Watch care­fully for other vehicles.

Do not ride in areas posted “no trespassing”.
Do not ride on private property without getting
permission.

7-20

Select a large, flat area off-road to become fa­miliar 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. Al­ways avoid riding on paved surfaces: the ATV
is designed for off-road use only, and han­dling 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. As you get on the ATV, be sure not
to accidentally move the shift pedal. 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, lift the shift pedal to the
1st gear position and then release the parking
brake. Apply the throttle slowly and smoothly.
The centrifugal clutch will engage and you will
start to accelerate. Once the ATV has at­tained adequate speed, release the throttle
and lift the shift pedal to the 2nd gear position.
Release the shift pedal and apply the throttle
smoothly. 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.

7-21

CAUTION:

_

Do not shift gears without releasing the
throttle. Damage to the engine or drive
train may occur.

_

When slowing down or stopping, release the
throttle 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 control and in­creasing the possibility of an accident.

WARNI NG

POTENTIAL HAZARD
Engaging a lower gear when the engine
speed is too high.
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.

7-22

TURNING YOUR ATV

To achieve maximum traction while riding off­road, 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.

WARNI NG

POTENTIAL HAZARD
Turning improperly.

WHAT CAN HAPPEN
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.

7-23

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 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.

7-24

CLIMBING UPHILL

Use proper riding techniques to avoid vehicle
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.

WARNI NG

POTENTIAL HAZARD
Operating on excessively steep hills.

WHAT CAN HAPPEN
The vehicle 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.

7-25

WARNI NG

POTENTIAL HAZARD
Climbing hills improperly.
WHAT CAN HAPPEN
Could cause loss of control or cause the
ATV to overturn.
HOW TO AVOID THE HAZARD
Always follow proper procedures for
climbing hills as described in this Own­er’s Manual.
Always 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.
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.

7-26

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.

WARNI NG

POTENTIAL HAZARD
Improperly crossing hills or turning on
hills.
WHAT CAN HAPPEN
Could cause loss of control or cause the
ATV to overturn.
HOW TO AVOID THE HAZARD
Never attempt to turn the ATV around
on any hill until you have mastered the
turning technique 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
possible.

When crossing the side of a hill:
Always follow proper procedures as de­scribed in the Owner’s Manual.
Avoid hills with excessively slippery or
loose surfaces.
Shift your weight to the uphill side of the
ATV.

7-27

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
either brake abruptly. If you are in 2WD, apply
only the front brake. When this ATV is in
4WD, all wheels (front and rear) are intercon­nected by the drive train. This means that ap­plying either the front brake or the rear will
brake all wheels. When descending hills, us­ing either brake lever or the brake pedal will
brake the wheels on the downhill side. Avoid
sudden application of either the front or rear
brake because the wheels on the uphill side
could come off the ground. The ATV could
easily tip over backwards. Apply both the front
and rear brakes gradually, or dismount the
ATV immediately on the uphill side.

WARNI NG

POTENTIAL HAZARD
Stalling, rolling backwards or improper­ly dismounting while climbing a hill.

WHAT CAN HAPPEN
Could result in ATV overturning.

HOW TO AVOID THE HAZARD
Use proper gear and maintain steady
speed when climbing a hill.
If you lose all forward speed:

Keep weight uphill.
Apply the brakes.
Lock parking brake, after you are
stopped.

If you begin rolling backwards:

Keep weight uphill.
2WD: Never apply the rear brake
while rolling backwards. Apply the
front brake.
4WD: Apply both front and rear
brakes gradually.
When fully stopped, lock the parking
brake.

7-28

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.

7-29

RIDING DOWNHILL

When riding your ATV downhill, shift your
weight as far to the rear and uphill side of the
ATV as possible. Move back on the seat and
sit with your arms straight. Engine compres­sion will do most of the braking for you. For
maximum engine compression braking effect,
change to 4WD before beginning to descend
the hill and choose a low gear which will allow
the engine compression to do most of the
braking for you. Improper braking may cause
a loss of traction. Use caution while descend­ing a hill with loose or slippery surfaces. Brak­ing ability and traction may be adversely
affected by these surfaces. Improper braking
may also cause a loss of traction.

When this ATV is in 4WD, all wheels (front
and rear) are interconnected by the drive
train. This means that applying either the front
brake or the rear brake will brake all wheels.
When descending hills, using either brake le­ver or the brake pedal will brake the wheels
on the downhill side. Avoid sudden applica­tion of either the front or rear brake because
the wheels on the uphill side could come off
the ground. Apply both the front and rear
brakes gradually.

Whenever possible, ride your ATV straight
downhill. Avoid sharp angles which could al­low the ATV to tip or roll over. Carefully
choose your path and ride no faster than you
will be able to react to obstacles which may
appear.
