SAFETY INFORMATION

SAFETY INFORMATION

EBU17442

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.
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:

Take a Training Course.

Beginners

– 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.

1

●

Never attempt wheelies, jumps, or other stunts.

●

Always inspect your ATV each time you use it to

2

make sure it is in safe operating condition. Al­ways follow the inspection and maintenance

3

procedures and schedules described in this
manual.

4

●

Always keep both hands on the handlebars and
both feet on the footboards of the ATV during

5

operation.

●

Always go slowly and be extra careful when op-

6

erating on unfamiliar terrain. Always be alert to
changing terrain conditions when operating the

7

ATV.

●

Never operate on excessively rough, slippery or

8

loose terrain until you have learned and prac-

9

ticed 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-

1-2

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.

Recommended fuel:

UNLEADED GASOLINE ONLY

Fuel reserve amount:

1.3 L (0.34 US gal) (0.29 Imp.gal)

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

4-8

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.

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.

There is never a more important period in the life of
your engine than the first 320 km (200 mi) or 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 320 km (200 mi) or 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.

160–320 km (100–200 mi) or 10–20 hours

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

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,
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.

EBU21070

Loading

As originally equipped, this ATV is not designed to
tow a trailer. If you choose to add accessories so
that you can 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.

MAXIMUM LOADING LIMIT

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

105.0 kg (231 lb)

Front carrier:

5.0 kg (11 lb)

Rear carrier:

10.0 kg (22 lb)

1

●

Load cargo on the carriers as close to the center
of the ATV as possible. Put cargo at the rear of

2

the front carrier, at the front of the rear carrier,
and center it.

3

●

Tie down cargo securely to the carriers. Make
sure cargo in the trailer cannot move around. A

4

shifting load can cause an accident.

●

Make sure the load does not interfere with con-

5

trols or your ability to see where you are going.

●

Ride more slowly than you would without a load.

6

The more weight you carry, the slower you
should go.

7

●

Allow more braking distance. A heavier ATV
takes longer to stop.

8

●

Avoid making sharp turns unless at very slow

9

speeds.

●

10

Avoid hills and rough terrain. Choose terrain
carefully. Added weight affects the stability and
handling of the ATV.

WARNING

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.

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. Re­member that the engine and exhaust pipe will be

7-15

nents.
With the engine idling, return the starter knob to the

2

closed position and shift the drive select lever into
the forward position. Then release the parking

3

brake. Apply the throttle slowly and smoothly. The
centrifugal clutch will engage and you will start to

4

accelerate. If the throttle is applied too abruptly, the
front wheels may lift off the ground, resulting in a

5

loss of directional control. Avoid higher speeds un­til you are thoroughly familiar with the operation of

6

your ATV.
When slowing down or stopping, release the throt-

7

tle and apply the brakes smoothly and evenly. Im­proper use of the brakes can cause the tires to lose

8

traction, reducing control and increasing the possi-

9

bility of an accident.

10

TURNING YOUR ATV

To achieve maximum traction while riding off-road,

11

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.

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.

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.

7-16

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
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.

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.)

Checking the spark plug

The spark plug is an important engine component,

4

which is easy to check. Since heat and deposits
will cause any spark plug to slowly erode, the spark

tion chart. In addition, the condition of the spark
plug can reveal the condition of the engine.

To check the spark plug

1. Check that the porcelain insulator around the
center electrode of the spark plug is a medi­um-to-light tan (the ideal color when the ATV
is ridden normally).

NOTE:

If the spark plug shows a distinctly different color,
the engine could be operating improperly. Do not
attempt to diagnose such problems yourself. In­stead, have a Yamaha dealer check the ATV.

2. Check the spark plug for electrode erosion
and excessive carbon or other deposits, and
