SAFETY INFORMATION

EBU13401

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. Begin-

ners 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 a passenger on an ATV.

TV on any paved surfaces, including sidewalks, driveways, park-

ing lots and streets.

●Never operate an ATV on any public street, road or highway, even a dirt or gravel one.

U5UH10.book Page 1 Monday, July 28, 2003 5:15 PM

2-2

●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 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. Al-

ways follow the inspection and maintenance procedures and schedules described in this man-

ual.

●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 prac-

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

o 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.

U5UH10.book Page 2 Monday, July 28, 2003 5:15 PM

2-3

●Always follow proper procedures for climbing hills as described in this manual. Check the ter-

rain 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 back-

ward. 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 roll backwards, follow the special procedure for

braking described in this manual. Dismount on the uphill side or to a side if pointed straight up-

hill. 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

e rocks or fallen trees. Always follow proper procedures when op-

erating over obstacles as described in this manual.

U5UH10.book Page 3 Monday, July 28, 2003 5:15 PM

2-4

●Always be careful when skidding or sliding. Learn to safely control skidding or sliding by prac-

ticing 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 con-

trol.

●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.

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

WARNING

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 differ-

ently. 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

from 2WD to 4WD or vice-versa.

U5UH10.book Page 7 Monday, July 28, 2003 5:15 PM

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.

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 le-

ver is released.

WARNING

POTENTIAL HAZARD

Malfunction of throttle.

WHAT CAN HAPPEN

The throttle could be hard to operate,

making it difficult to speed up or slow

down when you need to. This could

cause an accident.

HOW TO AVOID THE HAZARD

Check the operation of the throttle lever

before you start the engine. If it does not

work smoothly, check for the cause.

Correct the problem before riding the

ATV. Consult a Yamaha dealer if you

can’t find or solve the problem yourself.

Fuel

Make sure there is sufficient gasoline in the

tank.

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.

EBU02101

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 oper-

ation or any condition which might result in ex-

cessive engine heating must be avoided.

However, momentary (2–3 seconds maxi-

mum) full throttle operation under load does

not harm the engine.

Each full throttle acceleration sequence

should be followed with a substantial rest pe-

riod 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 peri-

od, consult a Yamaha dealer.

0–10 hours:

Avoid continuous operation above half throt-

tle. Allow a cooling off period of five to ten min-

utes after every hour of operation. Vary the

speed of the machine from time to time. Do

not operate it at one set throttle position.

U5UH10.book Page 7 Monday, July 28, 2003 5:15 PM

10–20 hours:

Avoid prolonged operation above 3/4 throttle.

Rev the machine freely but do not use full

throttle at any time.

After break-in:

Avoid prolonged full throttle operation. Vary

speeds occasionally.

WARNING

POTENTIAL HAZARD

Parking on a hill or other incline.

WHAT CAN HAPPEN

The ATV could roll out of control, in-

creasing the chance of an accident.

HOW TO AVOID THE HAZARD

Avoid parking on hills or other inclines.

If you must park on an incline, place the

machine transversely across the in-

cline, 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.

Accessories and loading

EBU00222

Accessories

Accessories can affect the handling and con-

trol 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 ac-

cessories may also be available on the

market. However, it is not possible for

Yamaha to test all non-Yamaha accesso-

ries, nor have any control over the quality or

suitability of them. Choose a genuine

Yamaha accessory, or one that is equiva-

lent in design and quality.

●Accessories should be rigidly and securely

mounted. An accessory which can shift po-

sition 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 han-

dlebars 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 differ-

ently than it does without accessories.

EBU12461

Cargo or a trailer can change the stability and

handling of an ATV.

You must use common sense and good judg-

ment 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.

●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 trail-

er, include the tongue weight in the maxi-

mum vehicle load limit.

●Load cargo on the carrier as close to the

center of the vehicle as possible. Put cargo

at the rear of the front carrier and 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 acci-

dent.

●Make sure the load does not interfere with

controls or your ability to see where you are

going.

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: 2.0 kg (4.4 lb)

●Trailer hitch:

Pulling load (total weight of trailer

Tongue weight (vertical weight on

trailer hitch point): 15 kgf (33 lbf)

U5UH10.book Page 11 Monday, July 28, 2003 5:15 PM

6-12

●Ride more slowly than you would without a

load. The more weight you carry, the slow-

er you should go.

●Allow more braking distance. A heavier ve-

hicle takes longer to stop.

●Avoid making sharp turns unless at very

slow speeds.

●Avoid hills and rough terrain. Choose ter-

rain carefully. Added weight affects the sta-

bility and handling of the ATV.

WARNING

POTENTIAL HAZARD

Overloading this ATV or carrying or tow-

ing cargo improperly.

WHAT CAN HAPPEN

Could cause changes in vehicle han-

dling which could lead to an accident.

HOW TO AVOID THE HAZARD

Never exceed the stated load capacity

for this ATV.

Cargo should be properly distributed

and securely attached.

Reduce speed when carrying cargo or

fully for other vehicles.

U5UH10.book Page 20 Monday, July 28, 2003 5:15 PM

7-21

Select a large, flat area off-road to become fa-

miliar 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 try-

ing 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 per-

form on pavement.

Set the parking brake and follow the instruc-

tion 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 ex-

haust pipe will be hot when riding and after-

wards; 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, shift the drive

select lever into the forward position, and then

release the parking brake. Apply the throttle

slowly and smoothly. The centrifugal clutch

will engage and you will start to accelerate. If

the throttle is applied too abruptly, the front

wheels may lift off the ground resulting in a

loss of directional control. Avoid higher

speeds until you are thoroughly familiar with

the operation of your ATV.

When slowing down or stopping, release the

throttle and apply the brakes smoothly and

evenly. Improper use of the brakes can cause

the tires to lose traction, reducing control and

increasing the possibility of an accident.

U5UH10.book Page 21 Monday, July 28, 2003 5:15 PM

7-22

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 in-

side 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 es-

sential that this skill be learned first at low

speed.

As you approach a curve, slow down and be-

gin to turn the handlebars in the desired direc-

tion. 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 maneu-

ver will let the wheel on the inside of the turn

slip slightly, allowing the ATV to make the turn

properly.

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 at-

tempting to turn at faster speeds. Do not

turn at speeds too fast for your skills or

the conditions.

U5UH10.book Page 22 Monday, July 28, 2003 5:15 PM

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

If the riding sur-

face is slippery or loose, it may help to posi-

tion 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 in-

side. 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.

U5UH10.book Page 23 Monday, July 28, 2003 5:15 PM

7-24

CLIMBING UPHILL

Use proper riding techniques to avoid vehicle

overturns on hills. Be sure that you can ma-

neuver your ATV well on flat ground before at-

tempting 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 sur-

faces, or obstacles that might cause you to

lose control.

It is important when climbing a hill to make

sure that your weight is transferred forward on

the ATV. This can be accomplished by lean-

ing forward and, on steeper inclines, standing

on the footboards and leaning forward over

the handlebars.

WARNING

POTENTIAL HAZARD

Operating on excessively steep hills.

WHAT CAN HAPPEN

The vehicle can overturn more easily on

extremely steep hills than on level sur-

faces 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.

vehicle or person could be on the other

side of the hill.

U5UH10.book Page 25 Monday, July 28, 2003 5:15 PM

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.

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 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.

U5UH10.book Page 26 Monday, July 28, 2003 5:15 PM

7-27

When crossing the side of a hill:

Always follow proper procedures as de-

scribed in the Owner’s Manual.

Avoid hills with excessively slippery or

loose surfaces.

Shift your weight to the uphill side of the

ATV.

U5UH10.book Page 27 Monday, July 28, 2003 5:15 PM

7-28

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, dis-

mount 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 intercon-

nected by the drive train. This means that ap-

plying 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

e 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.

WARNING

POTENTIAL HAZARD

Stalling, rolling backwards or improper-

ly dismounting while climbing a hill.

WHAT CAN HAPPEN

Could result in ATV overturning.

HOW TO AVOID THE HAZARD

Maintain steady speed when climbing a

hill.

If you lose all forward speed:

Keep weight uphill.

Apply the brakes.

Apply the parking brake after you are

stopped.

U5UH10.book Page 28 Monday, July 28, 2003 5:15 PM

7-29

If you begin rolling backwards:

Keep weight uphill.

2WD: Never apply the rear brake

while rolling backwards. Apply the

front brake. When fully stopped, ap-

ply the rear brake as well, and then

lock the parking brake.

4WD: Apply both front and rear

brakes gradually. When fully stopped,

lock the parking brake.

Dismount on uphill side or to a side if

pointed straight uphill. Turn the ATV

around and remount, following the pro-

cedure described in the Owner’s Manu-

al.

U5UH10.book Page 29 Monday, July 28, 2003 5:15 PM

7-30

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 compres-

sion 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 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 le-

ver or the brake pedal will brake the wheels

on the downhill side. Avoid sudden applica-

tion 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 al-

low 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.

WARNING

POTENTIAL HAZARD

Going down a hill improperly.

WHAT CAN HAPPEN

Could cause loss of control or cause the

ATV to overturn.

Always follow proper procedures for go-

ing down hills as described in this Own-

er’s Manual. Note: a special technique is

required when braking as you go down

a hill.

HOW TO AVOID THE HAZARD

Always check the terrain carefully be-

fore 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

lean sharply

to one side. Go straight down the hill

where possible.

CROSSING A SLOPE

Traversing a sloping surface on your ATV re-

quires 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 sur-

faces by pointing the front wheels slightly up-

hill. When riding on slopes be sure not to

make sharp turns either up or down hill.

If your ATV does begin to tip over, gradually

steer in the downhill direction if there are no

regain proper

balance, gradually steer again in the direction

you wish to travel.

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 hill until you have mastered the

turning technique as described in the

upset or accident. Be sure to keep your feet

firmly mounted on the footboards at all times.

Avoid jumping the ATV as loss of control and

damage to the ATV may result.

WARNING

POTENTIAL HAZARD

Improperly operating over obstacles.

WHAT CAN HAPPEN

Could cause loss of control or a colli-

sion. Could cause the ATV to overturn.

HOW TO AVOID THE HAZARD

Before operating in a new area, check

for obstacles.

Never attempt to ride over large obsta-

cles, such as large rocks or fallen trees.

When you go over obstacles, always fol-

low proper procedures as described in

the Owner’s Manual.

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, position-

ing 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 direc-

tion of the slide. Applying the brakes or accel-

erating is not recommended until you have

corrected the slide.

U5UH10.book Page 38 Monday, July 28, 2003 5:15 PM

7-39

With practice, over a period of time, skill at

controlled sliding can be developed. The ter-

rain should be chosen carefully before at-

tempting 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.

WARNING

POTENTIAL HAZARD

Skidding or sliding improperly.

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 slid-

ing 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 pages 7-22–7-23.)

●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 pag-

●If your ATV starts to slide sideways:

Steer in the direction of the slide if you have

the room. Applying the brakes or accelerat-

ing is not recommended until you have cor-

rected the slide. (See pages 7-38–7-39.)

●If your ATV can’t make it up a hill you are

trying to climb:

Turn the ATV around if you still have for-

ward 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 pages 7-24–7-29.)

U5UH10.book Page 40 Monday, July 28, 2003 5:15 PM

7-41

●If your ATV is traversing a sloping surface:

Be sure to ride with your weight positioned

towards the uphill side of the ATV to main-

tain 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 dis-

cover that the ATV is going to tip over, dis-

mount on the uphill side. (See pages 7-32–

7-33.)

●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 un-

til you have regained adequate braking

ability. (See pages 7-34–7-36.)

Brake fluid level check

Insufficient brake fluid may let air enter the

brake system, possibly causing the brakes to

become ineffective.

Before riding, check that the brake fluid is

above the minimum level mark and replenish

if necessary. A low brake fluid level may indi-

cate worn brake pads and/or brake system

leakage. If the brake fluid level is low, be sure

to check the brake pads for wear and the

brake system for leakage.

1. Minimum level mark

Observe these precautions:

●When checking the brake fluid level, make

sure the top of the brake fluid reservoir is

level.

●Use only the designated quality brake fluid,

otherwise, the rubber seals may deterio-

rate, causing leakage and poor brake per-

formance.

●Refill with the same type of brake fluid. Mix-

ing fluids may result in a harmful chemical

reaction and lead to poor brake perfor-

mance.

●Be careful that water does not enter the

brake fluid reservoir when refilling. Water

will significantly lower the boiling point of

the fluid and may result in vapor lock.

Troubleshooting

Although Yamaha machines receive a rigid in-

spection before shipment from the factory,

trouble may occur during operation. Any prob-

lem in the fuel, compression, or ignition sys-

tems can cause poor starting and loss of

power. The troubleshooting chart describes a

quick, easy procedure for making checks. If

your machine requires any repair, take it to a

Yamaha dealer.

The skilled technicians at a Yamaha dealer-

ship have the tools, experience, and know-

how to properly service your machine. Use

only genuine Yamaha parts on your machine.

Imitation parts may look like Yamaha parts,

but they are often inferior. Consequently, they

have a shorter service life and can lead to ex-

pensive repair bills.

CLEANING AND STORAGE

A. CLEANING

Frequent, thorough cleaning of your machine

will not only enhance its appearance but will

improve its general performance and extend

the useful life of many components.

1. Before cleaning the machine:

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 wheel axles.

3. Rinse the dirt and degreaser off with a

garden hose. Use only enough pressure

CAUTION:

Excessive water pressure may cause wa-

ter seepage and deterioration of wheel

bearings, brakes, transmission seals and

electrical devices. Many expensive repair

bills have resulted from improper high

pressure detergent applications such as

those available in coin-operated car wash-

ers.

4. Once the majority 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-get-at places.

5. Rinse the machine off immediately with

clean water and dry all surfaces with a

chamois, clean towel or soft absorbent

cloth.

U5UH10.book Page 1 Monday, July 28, 2003 5:15 PM

9-2

6. Clean the seat with a vinyl upholstery

cleaner to keep the cover pliable and

glossy.

7. 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,

start the engine and let it idle for several

minutes.

WARNING

POTENTIAL HAZARD

Operation with wet brakes after wash-

ing.

WHAT CAN HAPPEN

Wet brakes may have reduced stopping

ability, increasing the chance of an acci-

dent.

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.

EBU00530

B. STORAGE

Long term storage (60 days or more) of your

machine will require some preventive proce-

dures to guard against deterioration. After

thoroughly cleaning the machine, prepare for

storage as follows:

1. Fill the fuel tank with fresh fuel and add

the specified amount of Yamaha Fuel

Stabilizer and Conditioner or an equiva-

lent product.

TE:

Use of fuel stabilizer and conditioner elimi-

l system. Con-

sult a Yamaha dealer if the fuel system needs

to be drained instead.

2. Remove the spark plug, pour about one

tablespoon of SAE 10W30 or 20W40

motor oil in the spark plug hole and rein-

stall the spark plug. Ground the spark

plug wire and turn the engine over seve-

ral times to coat the cylinder wall with oil.

3. Lubricate all control cables.

4. Block up the frame to raise all wheels off

the ground.

5. Tie a plastic bag over the exhaust pipe

outlet to prevent moisture from entering.

6. If storing in a humid or salt-air atmo-

sphere, coat all exposed metal surfaces

with a light film of oil. Do not apply oil to

any rubber parts or the seat cover.

Specified amount:

1 oz of stabilizer to each gallon of fuel

(or 7.5 cc of stabilizer to each liter of

fuel)

7. Remove the battery and charge it. Store

it in a dry place and recharge it once a

month. Do not store the battery in an ex-

cessively warm or cold place (less than

0°C (30 °F) or more than 30 °C (90 °F)).

TE:

Make any necessary repairs before storing

the machine.
