SAFETY INFORMATION

EBU17542

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 fol-

low the operating procedures described.

● Never operate an ATV without proper training or

instruction. Take a Training Course.
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:

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

Beginners

1

● 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 ap-

proved 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.

1-1

● Always inspect your ATV each time you use it to

make sure it is in safe operating condition. Al-

1

ways 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 op-

erating 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. 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. Maintain a
steady speed when climbing a hill. If you stall or

1-2

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 de-

scribed in this manual.

● Never modify an ATV through improper installa-

tion 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.

FOR MORE INFORMATION ABOUT ATV SAFE­TY, call the Consumer Products Safety Commis-

sion at 1-800-638-2772, or the ATV Distributor’s
Safety Hotline at 1-800-852-5344.

EWB00120

WARNING

POTENTIAL HAZARD
Changing from two-wheel drive to four­wheel drive or from four-wheel drive to two­wheel drive while the ATV is moving.

WHAT CAN HAPPEN
The ATV handles differently in two-wheel
drive than in four-wheel drive in some cir­cumstances. Changing from two-wheel drive
to four-wheel drive or from four-wheel drive
to two-wheel drive while moving may cause
the ATV to unexpectedly handle differently.
This could distract the operator and in­crease the risk of losing control and of caus­ing an accident.
HOW TO AVOID THE HAZARD
Always stop the ATV before changing from
two-wheel drive to four-wheel drive or vice­versa.

EBU18270

Throttle lever

Once the engine is running, movement of the throt­tle lever will increase the engine speed.
Regulate the speed of the ATV by varying the
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.

4

4-6

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.

4-11

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
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 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.

EWB00270

WARNING

POTENTIAL HAZARD
Improper care when refueling.

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.

Engine break-in

There is never a more important period in the life of
your engine than the first 20 hours of riding. For
this reason, you should read the following material
carefully.

Since the engine is brand new, do not put an ex­cessive load on it for 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 that might result in engine overheating must be
avoided.

0–10 hours

Avoid prolonged operation above 1/2 throttle. Vary
the speed of the ATV regularly. Do not operate it at
one set throttle position.

10–20 hours

Avoid prolonged operation above 3/4 throttle. Rev
the engine freely, but do not use full throttle at any
time.

EBU20910

Accessories and loading

EBU20920

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,

6-6

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 inter-

fere with your ability to control the ATV. Exam­ples include (but are not limited to) a heavy or

6

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 ac-

cessories. The ATV may handle differently than
it does without accessories.

EBU21050

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 over-

loaded ATV can be unstable.

MAXIMUM LOADING LIMIT

ATV loading limit (total weight of rider, cargo,
accessories, and tongue):

210.0 kg (463 lb)

Front carr ier:

40.0 kg (88 lb)

Rear carrier:

80.0 kg (176 lb)

Storage compartment:

2.0 kg (4 lb)

Trailer hitch:

Pulling load (total weight of trailer and car­go):

4900 N (1102 lbf) (500 kgf)
Tongue weight (vertical weight on trailer
hitch point):

147 N (33 lbf) (15 kgf)

● 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

6-7

the weight on the hitch. 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 con-

trols 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.

EWB00750

WARNING

POTENTIAL HAZARD

7-16

7

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

7

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, 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.
Shift to the park position 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, return the starter (choke) to
the closed position, and shift the drive select lever
into the forward position. 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 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.

7-17

EWB01080

WARNING

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.

1. Lean towards inside of turn.

2. Support your weight on the outer footboard.

7

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.

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.

7-18

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

7

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.

EWB01090

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 to overturn.

7-19

HOW TO AVOID THE HAZARD
Always follow proper procedures for climb­ing hills as described in this Owner’s Manu-
al.
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. 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

7-20

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.

EWB01190

WARNING

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

7

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.

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.

7-21

If you start to roll backwards, DO NOT apply either
brake abruptly. If you are in 2WD, apply only the
front brake. If you are in 4WD, because all wheels
are interconnected by the drive train, applying ei­ther brake will brake all wheels, therefore, avoid
sudden application of either the front or rear brake
as 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.

EWB01361

WARNING

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
Maintain a steady speed when climbing a
hill.
If you lose all forward speed:

● Keep weight uphill.

● Apply the brakes.

● Shift to the park position after you are

stopped.

If you begin rolling backwards:

● Keep weight uphill.

● 2WD: Never apply the rear brake while roll-

ing backwards. Apply the front brake.
When fully stopped, shift to the park posi­tion.

● 4WD: Apply both front and rear brakes

gradually. When fully stopped, shift to the

park position.
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

7-22

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. 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

7

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.

EWB01130

WARNING

POTENTIAL HAZARD
Going down a hill 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 going
down hills as described in this Owner’s Man­ual.
Note: a special technique is required when
braking as you go down a hill.
Always 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 ATV to lean sharply to one
side. Go straight down the hill where possi­ble.

7-23

7-2477-25

CROSSING A SLOPE

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
slopes, be sure not to make sharp turns either up
or down hill.

7

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.

EWB01141

WARNING

POTENTIAL HAZARD
Improperly crossing hills or turning on hills.
WHAT CAN HAPPEN

7-30

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.

7

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.

EWB01170

WARNING

POTENTIAL HAZARD
Skidding or sliding improperly.

7-31

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.

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 7-17.)

● 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:

Steer in the direction of the slide if you have the
room. Applying the brakes or accelerating is not
recommended until you have corrected the
slide. (See page 7-31.)

● 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 IF THE ATV IS IN 2WD –
the ATV may tip over on top of you. Dismount
the ATV on the uphill side. (See page 7-19.)

● 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 7-19.)
