SAFETY INFORMATION

EBU17576

AN ATV IS NOT A TOY AND CAN BE HAZARD- OUS TO OPERATE. An ATV handles differently from other vehicles, in- cluding motorcycles and cars. A collision or roll- over can occur quickly, even during routine maneuvers such as turning and riding on hills or over obstacles, if you fail to take proper precau- tions. 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. Beginners should receive training from a certified instruc- tor. 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 oper- ate 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, park- ing 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.

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 manual.

Always keep both hands on the handlebars and both feet on the footrests of the ATV during op- eration.

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 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 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 ter- rain carefully before you start up any hill. Never climb hills with excessively slippery or loose sur- faces. 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 ve- hicle 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 sur- faces. 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 tech- nique described in this manual on level ground. Avoid crossing the side of a steep hill if possible.

Always use proper procedures if you stall or roll backwards when climbing a hill. To avoid stall- ing, use the proper gear and maintain a steady

U1BT10E0.book Page 2 Monday, June 8, 2009 11:10 AM

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 large obstacles, such as large rocks or fallen trees. Always follow proper procedures when operating over obsta- cles 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 re- duce 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 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 in- structions in this manual for carrying cargo or pulling a trailer. Allow greater distance for brak- ing.

WARNING EWB00071

Avoid Carbon Monoxide Poisoning All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide can cause headaches, dizziness, drowsiness, nau- sea, confusion, and eventually death. Carbon Monoxide is a colorless, odorless, tasteless gas which may be present even if you do not see or smell any engine exhaust. Deadly levels of carbon monoxide can collect rapidly and you can quickly be overcome and unable to save yourself. Also, deadly levels of carbon monoxide can linger for hours or days in en- closed or poorly ventilated areas. If you experi- ence any symptoms of carbon monoxide poisoning, leave the area immediately, get fresh air, and SEEK MEDICAL TREATMENT. Do not run engine indoors. Even if you try to

ventilate engine exhaust with fans or open windows and doors, carbon monoxide can rapidly reach dangerous levels.

Do not run engine in poorly ventilated or par- tially enclosed areas such as barns, garages, or carports.

Do not run engine outdoors where engine exhaust can be drawn into a building through openings such as windows and doors.

WARNING EWB02591

When transporting the ATV in another vehicle, be sure it is kept upright and that the fuel cock is in the OFF position. Otherwise, fuel may leak out of the carburetor or fuel tank.

Fuel Make sure there is sufficient gasoline in the tank.

WARNING EWB02521

Gasoline and gasoline vapors are extremely flammable. To avoid fires and explosions and to reduce the risk of injury when refueling, fol- low these instructions.

1. Before refueling, turn off the engine and be sure that no one is sitting on the vehicle. Nev- er refuel while smoking, or while in the vicinity

of sparks, open flames, or other sources of ig- nition such as the pilot lights of water heaters and clothes dryers.

2. Do not overfill the fuel tank. When refueling, be sure to insert the pump nozzle into the fuel tank filler hole. Stop filling when the fuel reach- es the bottom of the filler tube. Because fuel expands when it heats up, heat from the en- gine or the sun can cause fuel to spill out of the fuel tank.

4. Turn the fuel tank cap fully clockwise to make sure it is securely closed.

WARNING EWB02531

Gasoline is poisonous and can cause injury or death. Handle gasoline with care. Never siphon gasoline by mouth. If you should swallow some gasoline or inhale a lot of gasoline vapor, or get some gasoline in your eyes, see your doctor immediately. If gasoline spills on your skin, wash with soap and water. If gasoline spills on your clothing, change your clothes.

NOTICE ECB00070

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 oc- tane number of 91 or higher. If knocking (or ping- ing) occurs, use a gasoline of a different brand. Use of unleaded fuel will extend spark plug life and reduce maintenance costs.

Gasohol There are two types of gasohol: gasohol contain- ing ethanol and that containing methanol. Gasohol containing ethanol can be used if the ethanol con- tent does not exceed 10% (E10). Gasohol contain- ing methanol is not recommended by Yamaha because it can cause damage to the fuel system or vehicle performance problems.

Recommended fuel: UNLEADED GASOLINE ONLY

Fuel tank capacity: 9.0 L (2.38 US gal, 1.98 Imp.gal)

Fuel reserve amount: 1.0 L (0.26 US gal, 0.22 Imp.gal)

4. Open the throttle gradually and at the same time, release the clutch lever slowly. WARNING! Opening the throttle abruptly or releasing the clutch lever too quickly could make the ATV wheelie, which would increase the chance of an accident, includ- ing an overturn. [EWB00731]

5. Once the ATV has attained adequate speed, release the throttle, and at the same time, quickly pull in the clutch lever.

6. Shift the transmission into second gear. (Make sure not to shift the transmission into neutral.)

7. Open the throttle part way and gradually re- lease the clutch lever.

8. Follow the same procedure when shifting to the next higher gear.

EBU20650

To decelerate When slowing down or stopping, release the throt- tle 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 con- trol and increasing the possibility of an accident.

WARNING EWB00710

Make sure the engine has sufficiently slowed before shifting to a lower gear. Engaging a low- er gear when the engine speed is too high could make the wheels stop rotating and lose traction. This could cause loss of control, an accident and injury. It could also cause engine or drive train damage.

NOTICE ECB00180

Even with the transmission in the neutral po- sition, do not coast for long periods of time with the engine off, and do not tow the ATV for long distances. The transmission is prop- erly lubricated only when the engine is run- ning. Inadequate lubrication may damage the transmission.

Always use the clutch when changing gears. The engine, transmission and drive train are not designed to withstand the shock of forced shifting and can be damaged by shift- ing without using the clutch.

Engine break-in

TIP For ATVs equipped with an odometer or an hour

meter, follow the figures given in km (mi) or the figures given in hours.

For ATVs not equipped with an odometer or hour meter, follow the figures given in hours.

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 ex- cessive 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 clear- ances. During this period, prolonged full-throttle operation or any condition that might result in en- gine overheating must be avoided.

0160 km (0100 mi) or 010 hours Avoid prolonged operation above 1/2 throttle. Vary the speed of the ATV regularly. Do not operate it at one set throttle position.

160320 km (100200 mi) or 1020 hours Avoid prolonged operation above 3/4 throttle. Rev the engine through the gears freely, but do not use full throttle at any time.

320 km (200 mi) or 20 hours and beyond The ATV can now be operated normally.

Accessories and loading

EBU20921

Genuine Yamaha Accessories Choosing accessories for your ATV is an important decision. Genuine Yamaha Accessories, which are available only from a Yamaha dealer, have been designed, tested, and approved by Yamaha for use on your ATV. Many companies with no con- nection to Yamaha manufacture parts and acces- sories or offer other modifications for Yamaha vehicles. Yamaha is not in a position to test the products that these aftermarket companies pro- duce. Therefore, Yamaha can neither endorse nor recommend the use of accessories not sold by Yamaha or modifications not specifically recom- mended by Yamaha, even if sold and installed by a Yamaha dealer.

Aftermarket parts, accessories, and modifica- tions While you may find aftermarket products similar in design and quality to genuine Yamaha Accesso- ries, recognize that some aftermarket accessories or modifications are not suitable because of poten- tial safety hazards to you or others. Installing after-

market products or having other modifications performed to your ATV that change any of the ve- hicles design or operation characteristics can put you and others at greater risk of serious injury or death. You are responsible for injuries related to changes in the vehicle. Keep the following in mind when considering an accessory or operating an ATV which has acces- sories. 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. Exam- ples 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 ac- cessories. The ATV may handle differently than it does without accessories.

Loading

WARNING EWB00820

Never exceed the stated load capacity for this ATV. Overloading this ATV or carrying or tow- ing cargo improperly could cause changes in ATV handling which could lead to an accident. Cargo should be properly distributed and se- curely attached. Reduce speed when carrying cargo or pulling a trailer. Allow greater dis- tance for braking.

As originally equipped, this ATV is not designed to carry cargo or tow a trailer. If you choose to add ac- cessories so that you can carry cargo or tow a trail- er, 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 over-

loaded ATV can be unstable.

If you are carrying cargo and towing a trailer, in- clude 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. Although conditions vary, it is good practice not to exceed 2nd gear whenever you are carrying heavier loads or when towing a trail- er.

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.

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

7 Do not ride in areas posted no trespassing. Do not ride on private property without getting per- mission.

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. 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. With the engine idling, pull the clutch lever to disengage the clutch and shift into 1st gear, and then release the parking brake. Open the throttle gradually, and at the same time, re- lease the clutch lever slowly. Once the ATV has at- tained adequate speed, release the throttle lever and at the same time, quickly pull in the clutch le- ver and shift into 2nd gear. Open the throttle part way and gradually release the clutch. WARNING! 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 con-

trol. [EWB02631] NOTICE: Do not shift gears without releasing the throttle. Damage to the engine or drive train may occur. [ECB01071]

Use this same procedure as you move into the higher gears. Be sure to coordinate the use of the throttle and shift pedal properly. Avoid higher speeds until you are thoroughly famil- iar with the operation of your ATV. When slowing down or stopping, release the throt- tle 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 con- trol and increasing the possibility of an accident.

TURNING YOUR ATV

WARNING EWB01771

Always follow proper procedures for turning as described in this Owners 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. ATV could go out of control, causing a collision or overturn.

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 tech- nique 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. 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 footrest 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.

U1BT10E0.book Page 12 Monday, June 8, 2009 11:10 AM

7-13

7

This procedure should be practiced at slow speed many times in a large off-road area with no obsta- cles. If an incorrect technique is used, your ATV may continue to go straight. If the ATV doesnt turn, come to a stop and then practice the proce- dure 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 move- ments, 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 out- side of the turn to avoid tipping over. Remember: Avoid higher speeds until you are thoroughly familiar with the operation of your ATV.

CLIMBING UPHILL

WARNING EWB01591

Climbing hills improperly can cause overturns or loss of control. Use proper riding tech- niques described in this Owners Manual. Never operate the ATV on hills too steep for

the ATV or for your abilities. The ATV can overturn more easily on extremely steep hills than on level surfaces or small hills.

Always check the terrain carefully before you start up any hill. Never climb hills with excessively slippery or loose surfaces.

Shift your weight forward.

1. Lean towards inside of turn. 2. Support your weight on the outer footrest.

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.

Never attempt to turn the ATV around on any hill until you have mastered the turning tech- nique as described in the Owners Manual on level ground. Be very careful when turning on any hill.

Avoid crossing the side of a steep hill if pos- sible. When crossing the side of a hill, shift your weight to the uphill side of the ATV.

U1BT10E0.book Page 14 Monday, June 8, 2009 11:10 AM

7

Do not attempt to climb hills until you have mas- tered basic maneuvers on flat ground. Always check the terrain carefully before attempting any hill. In all cases avoid inclines with slippery or loose surfaces, or obstacles that might cause you to lose control. To climb a hill, you need traction, momentum, and steady throttle. Travel fast enough to maintain mo- mentum, but not so fast that you cannot react to changes in the terrain as you climb.

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 footrests and leaning forward over the handlebars. Whenever possible, ride straight up hills. Slow down when you reach the crest of the hill if you cannot see clearly what is on the other side there could be another person, an obstacle, or a sharp drop-off. Use common sense and remember that some hills are too steep for you to climb or de- scend. 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. 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 up- hill side. Physically turn the ATV around and then descend the hill.

If you start to roll backwards, DO NOT apply the rear brake, and apply the front brake gradually. The ATV could easily tip over backwards. When fully stopped, apply the rear brake as well, and then lock the parking brake. Dismount the ATV im- mediately on the uphill side or to a side if pointed straight uphill. Turn the ATV around and remount, following the procedure described in the Owners Manual. WARNING! Stalling, rolling backwards or improperly dismounting while climbing a hill could result in ATV overturning. If you cannot control the ATV, dismount immediately on the uphill side. [EWB01802]

RIDING DOWNHILL

WARNING EWB01131

Going down a hill improperly could cause overturns or loss of control. Always follow proper procedures for going down hills as de- scribed in this Owners Manual. Always check the terrain carefully before

you start down any hill. Never operate the ATV on hills too steep for

the ATV or for your abilities. The ATV can overturn more easily on extremely steep hills than on level surfaces or small hills.

Shift your weight backward and to the up side of the hill.

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 possi- ble.

Improper braking can cause the wheels on the uphill side to come off the ground or cause loss of traction. Gradually apply only the rear brake when going downhill.

When riding your ATV downhill, shift your weight as far to the rear and uphill side of the ATV as pos- sible. Move back on the seat and sit with your arms straight. Choose a low gear which will allow the en- gine compression to do most of the braking for you. 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. Gradual- ly apply only the rear brake. Whenever possible, ride your ATV straight down- hill. 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 ob- stacles which may appear.

CROSSING A SLOPE

WARNING EWB01632

Improperly crossing hills or turning on hills could cause loss of control or cause the ATV to overturn. Always follow proper procedures as de-

scribed in the Owners Manual. Avoid hills with excessively slippery or loose

surfaces.

Avoid crossing the side of a steep hill. 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 tech- nique as described in the Owners Manual on level ground. Be very careful when turning on any hill.

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 slip- pery 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. 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.

CROSSING THROUGH SHALLOW WATER

WARNING EWB01641

Operating this vehicle through deep or fast- flowing water can lead to loss of control or an overturn. To reduce your risk of drowning or other injuries, use care when crossing through water. Never operate this ATV water deeper

than the depth specified in your Owners Man- ual, as tires may float, increasing the risk of an overturn.

The ATV can be used to cross slow moving, shal- low water of up to a maximum of 35 cm (14 in) in depth. Before entering the water, choose your path carefully. Enter where there is no sharp drop off, and avoid rocks or other obstacles which may be slippery or upset the ATV. Drive slowly and care- fully.

Test your brakes after leaving the water. If neces- sary, apply them several times to let friction dry out the linings. Do not continue to ride your ATV with- out verifying that you have regained proper braking ability. WARNING! Wet brakes may have re- duced stopping ability, which could cause loss of control. [EWB02621]

After riding your ATV in water, be sure to drain the trapped water by removing the check hose at the bottom of the air filter case. NOTICE: Undrained water can cause damage or improper opera- tion. [ECB00841]

Wash the ATV in fresh water if it has been operat- ed in salt water or muddy conditions.

RIDING OVER ROUGH TERRAIN

WARNING EWB01651

Riding improperly over obstacles could cause loss of control or a collision. Before operating in a new area, check for obstacles. Never at- tempt to ride over large obstacles, such as large rocks or fallen trees. When you go over obstacles, always follow proper procedures as described in the Owners Manual.

Riding over rough terrain should be done with cau- tion. Look out for obstacles which could cause damage to the ATV or could lead to an upset or ac- cident. Be sure to keep your feet firmly mounted on the footrests at all times. Avoid jumping the ATV as loss of control and damage to the ATV may result.

SLIDING AND SKIDDING

WARNING EWB01662

Skidding or sliding improperly may cause you to lose control of this ATV. You may also re- gain traction unexpectedly, which may cause the ATV to overturn.

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 re- duce the chance of skidding or sliding out of control.

Care should be used when riding on loose or slip- pery surfaces since the ATV may slide. If unex- pected 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.

U1BT10E0.book Page 21 Monday, June 8, 2009 11:10 AM

7-22

7

If the rear wheels of your ATV start to slide side- ways, 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 con- trolled sliding can be developed. The terrain should be chosen carefully before attempting such maneuvers, since both stability and control are re- duced. Bear in mind that sliding maneuvers should always be avoided on extremely slippery surfaces such as ice, since all control may be lost.

WHAT TO DO IF... This section is designed to be a reference guide only. Be sure to read each section on riding tech- niques completely.

WHAT TO DO... If your ATV doesnt 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 footrest to the outside of the turn. Position your weight over the front wheels for better control. (See page 7-12.)

If your ATV begins to tip while turning: Lean more into the turn to regain balance. If nec- essary, gradually let off the throttle and/or steer to the outside of the turn. (See page 7-12.)

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 7-21.)

If your ATV cant make it up a hill you are trying to climb: Turn the ATV around if you still have forward speed. If not, stop, dismount on the uphill side of the ATV and physically turn the ATV around. If the ATV starts to slip backwards, DO NOT USE

THE REAR BRAKE the ATV may tip over on top of you. Dismount the ATV on the uphill side. (See page 7-13.)

If your ATV is traversing a sloping surface: Be sure to ride with your weight positioned to- wards the uphill side of the ATV to maintain proper balance. If the ATV starts to tip, steer down the hill (if there are no obstacles in your way) to regain balance. If you discover that the ATV is going to tip over, dismount on the uphill side. (See page 7-18.)

If your ATV encounters shallow water: Ride slowly and carefully through slow moving water, watching for obstacles. Be sure to let wa- ter drain from the ATV and CHECK YOUR BRAKES FOR PROPER OPERATION when you come out of the water. Do not continue to ride your ATV until you have regained adequate braking ability. (See page 7-19.)

Checking the spark plug The spark plug is an important engine component, which is easy to check. Since heat and deposits will cause any spark plug to slowly erode, the spark plug should be removed and checked in accor- dance with the periodic maintenance and lubrica- tion chart. In addition, the condition of the spark plug can reveal the condition of the engine.

To remove the spark plug 1. Remove the spark plug cap.

2. Remove the spark plug as shown, with the spark plug wrench included in the owners tool kit.

To check the spark plug 1. Check that the porcelain insulator around the

center electrode of the spark plug is a medi- um-to-light tan (the ideal color when the ATV is ridden normally).

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

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

TIP To check the rear brake fluid level, remove the res- ervoir cover by removing the bolts.

Observe these precautions: When checking the fluid level, make sure that

the top of the brake fluid reservoir is level. Use only the recommended quality brake fluid,

otherwise the rubber seals may deteriorate, causing leakage and poor braking performance.

Refill with the same type of brake fluid. Mixing fluids may result in a harmful chemical reaction and lead to poor braking performance.

Be careful that water does not enter the brake fluid reservoir when refilling. Water will signifi- cantly lower the boiling point of the fluid and may result in vapor lock.

Brake fluid may deteriorate painted surfaces or plastic parts. Always clean up spilled fluid imme- diately.

As the brake pads wear, it is normal for the brake fluid level to gradually go down. However, if the brake fluid level goes down suddenly, have a Yamaha dealer check the cause.

EBU24291

Changing the brake fluid Have a Yamaha dealer change the brake fluid at the intervals specified in the TIP after the periodic maintenance and lubrication chart.

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

CLEANING AND STORAGE EBU25902

Cleaning Frequent, thorough cleaning of your ATV will not only enhance its appearance but will improve its general performance and extend the useful life of many components.

1. Before cleaning the ATV: a. Block off the end of the exhaust pipe to

prevent water entry. A plastic bag and strong rubber band may be used.

b. Make sure the spark plug and all filler caps are properly installed.

2. If the engine case is excessively greasy, apply degreaser with a paint brush. Do not apply de- greaser to the chain, sprockets or wheel ax- les.

3. Rinse the dirt and degreaser off with a garden hose. Use only enough pressure to do the job. WARNING! Wet brakes may have reduced stopping ability, increasing the chance of an accident. Test the brakes after washing. Apply the brakes several times at slow speeds to let friction dry out the linings. [EWB02311] NOTICE: Excessive water pressure

may cause water seepage and deteriora- tion of wheel bearings, brakes, transmis- sion seals and electrical devices. Many expensive repair bills have resulted from improper high-pressure detergent applica- tions such as those available in coin-oper- ated car washers. [ECB00711]

4. Once most of the dirt has been hosed off, wash all surfaces with warm water and mild, detergent-type soap. An old toothbrush or bot- tle brush is handy for hard-to-reach places.

5. Rinse the ATV off immediately with clean wa- ter and dry all surfaces with a chamois, clean towel or soft absorbing cloth.

6. Dry the chain and lubricate it to prevent it from rusting.

7. Clean the seat with a vinyl upholstery cleaner to keep the cover pliable and glossy.

8. Automotive type wax may be applied to all painted and chrome plated surfaces. Avoid combination cleaner-waxes. Many contain abrasives which may mar the paint or protec- tive finish. When finished cleaning, start the engine and let it idle for several minutes.

Storage

Short-term Always store your ATV in a cool, dry place and, if necessary, protect it against dust with a porous cover. NOTICE: Storing the ATV in a poorly ven- tilated room or covering it with a tarp while it is still wet, will allow water and humidity to seep in and cause rust. To prevent corrosion, avoid damp cellars, stables (because of the presence of ammonia) and areas where strong chemi- cals are stored. [ECB00721]

Long-term Before storing your ATV for several months:

1. Follow all the instructions in the Cleaning section of this chapter.

2. Turn the fuel cock lever to OFF. 3. Drain the carburetor float chamber by loosen-

ing the drain bolt; this will prevent fuel deposits from building up. Pour the drained fuel into the fuel tank.

4. Fill up the fuel tank and add fuel stabilizer (if available) to prevent the fuel from deteriorat- ing.

5. Perform the following steps to protect the cyl- inder, piston rings, etc. from corrosion. a. Remove the spark plug cap and spark

plug. b. Pour a teaspoonful of engine oil into the

spark plug bore. c. Install the spark plug cap onto the spark

plug, and then place the spark plug on the cylinder head so that the electrodes are grounded. (This will limit sparking during the next step.)

d. Turn the engine over several times with the starter. (This will coat the cylinder wall with oil.)

e. Remove the spark plug cap from the spark plug, and then install the spark plug and the spark plug cap.

6. Lubricate all control cables and the pivoting points of all levers and pedals.

7. Check and, if necessary, correct the tire air pressure, and then block up the ATV so that all of its wheels are off the ground. Alternative-

Specified amount: 7.5 ml of stabilizer to each liter of fuel (or 1 oz of stabilizer to each gallon of fuel)

ly, turn the wheels a little every month in order to prevent the tires from becoming degraded in one spot.

8. Cover the muffler outlet with a plastic bag to prevent moisture from entering it.

9. Remove the battery and fully charge it. Store it in a cool, dry place and charge it once a month. Do not store the battery in an exces- sively cold or warm place [less than 0 C (30 F) or more than 30 C (90 F)]. For more in- formation on storing the battery, see page 8-36.

TIP Make any necessary repairs before storing the ATV.

TRIP gives you up to $150 reimbursement per occurrence for any reasonable expenses you incur because your Yamaha needs covered service: replacement vehicle rental, emergency towing, phone calls, even food and lodging when you are away from home. This superb coverage goes into effect when you purchase Y.E.S., so it applies to any warranty repairs as well as covered repairs during your entire Y.E.S. plan period.

Y.E.S. coverage is honored at any authorized Yamaha dealer nationwide.

Y.E.S. coverage is transferable to a new owner if you sell or trade in your ATV. That can make your Yamaha much more valuable!

This excellent Y.E.S. plan coverage is only available to Yamaha owners like you, and only while your Yamaha is still within the Yamaha Limited Warranty period. So visit your authorized Yamaha dealer to get all the facts. He can show you how easy it is to protect your investment with Yamaha Extended Service.
