SAFETY INFORMATION SAFETY INFORMATION

EBU27236

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.

UB5K13E0.book Page 1 Thursday, August 19, 2021 2:35 PM

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 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 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 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.

UB5K13E0.book Page 2 Thursday, August 19, 2021 2:35 PM

3-3

3

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

Do not operate your ATV during darkness un- less it is equipped with a properly functioning headlight. Off-road riding is inherently danger- ous and additionally, off-road trails do not have streetlights to guide you.

Never maintain an ATV without proper knowl- edge. Contact an authorized ATV dealer to in- form you on basic ATV maintenance. Certain maintenance can only be carried out by certified staff.

In the event of an accident 1. If serious injuries are incurred, you may be

safer staying next to your vehicle; it may shield you from oncoming riders. Depending on your injuries and position in the trail; you must make a judgment call as to whether you should move to a position off the trail. If you have sustained head, neck, or back injuries, or cannot feel your limbs, you should not move. Keep your helmet on and remain mo- tionless. Lie down next to your vehicle and wait for help.

2. If less serious injuries are incurred and you can walk, then move to a position off the trail. Check yourself for injuries and apply first aid as needed.

3. If your injuries are light, when safe to do so, move your vehicle off the trail to avoid colli- sions with oncoming riders. Check for injuries and apply first aid as necessary. If you can physically operate your vehicle, inspect your vehicle. If the vehicle is in safe operating con- dition and you can safely operate it, restart it and ride gently back to camp or other known location where you can receive medical at-

tention. If necessary, contact your riding party or local authorities to let them know where you are and what has happened.

In the event of a breakdown 1. If your vehicle will not restart or is not in safe

operating condition, turn off the main switch and engine stop switch. If the breakdown oc- curs at twilight or night, leave the main switch on so that your lights may warn other riders of your stopped vehicle.

2. Get out of danger. Check for oncoming vehi- cles and when safe, push your vehicle to the side of the trail or even off the main trail to avoid any possible collisions with oncoming riders. If you cannot move your vehicle by yourself, when safe, walk to the nearest van- tage point and signal an oncoming rider to help you push your vehicle to a safe place off the trail.

3. Inspect your vehicle for any immediate haz- ardous conditions. The most obvious hazard- ous conditions are leaking fuel and ungrounded or broken wiring. Visually check for broken wiring and leaking fuel. Leaking fuel can be confirmed by the odor of gasoline.

UB5K13E0.book Page 4 Thursday, August 19, 2021 2:35 PM

4. Once immediate safety hazards are con- firmed not to exist, you may remove your hel- met to more closely inspect your vehicle. Check for external signs of wear, broken parts, fluid leaks, cracks in the frame, sus- pension damage, wheel damage, and so on. Fuel, oil, and coolant usually give off a notice- able odor.

5. If your vehicle will not restart or if it is unsafe to ride, then turn off all vehicle systems (en- gine stop switch, main switch, and fuel co*ck), and then signal or go for help.

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 po- tential safety hazards to you or others. Installing aftermarket products or having other modifica- tions performed to your vehicle that change any of the vehicles design or operation characteristics can put you and others at greater risk of serious injury or death. You are responsible for injuries re- lated to changes in the vehicle. Keep the following

guidelines in mind, as well as those found in the Loading section (page 7-7) when mounting acces- sories. Never install accessories that would impair the

performance of your ATV. Carefully inspect the accessory before using it to make sure that it does not in any way reduce ground clearance, limit suspension travel, steering travel or control operation.

Accessories fitted to the ATV can create insta- bility due to improper weight distribution.

Bulky or large accessories may seriously affect the stability of the ATV.

Certain accessories can displace the operator from his or her normal riding position. This im- proper position limits the freedom of movement of the operator and may limit control ability, therefore, such accessories are not recom- mended.

Use caution when adding electrical accesso- ries. If electrical accessories exceed the capac- ity of the ATVs electrical system, an electric failure could result, which could cause a dan- gerous loss of lights or engine power. Also, the battery tends to discharge more quickly if elec- trical accessories are added.

WARNING EWB00073

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.

FOR MORE INFORMATION ABOUT ATV SAFE- TY, call the Consumer Products Safety Commis- sion at 1-800-638-2772, or the ATV Distributors Safety Hotline at 1-800-852-5344.

TIP If the digits of the speedometer appear as shown when the switch is NOT being pushed, this could indicate a malfunction in the electrical system. In this case, take the ATV to a Yamaha dealer at the first opportunity.

WARNING EWB00151

Always ride at a slow speed when the ATV is in four-wheel-drive differential gear lock, and al- low extra time and distance for maneuvers. All wheels turn at the same speed when the dif- ferential is locked, so it takes more effort to turn the ATV. The effort needed to turn increas-

es with the riding speed. You may lose control and have an accident if you cannot make a sharp enough turn for the speed you are trav- eling.

WARNING EWB00164

Always stop the ATV before changing from two-wheel drive to four-wheel drive and vice versa. The ATV handles differently in two- wheel drive than in four-wheel drive in some circ*mstances. Changing from two-wheel drive to four-wheel drive or vice versa while moving may cause the ATV to unexpectedly handle differently. This could distract the oper- ator and increase the risk of losing control and of causing an accident.

On-Command drive switch 4WD/LOCK (YFM70KPAN / YFM70KPHN / YFM70KPSN) Stop the ATV and push this switch to change from standard four-wheel drive to four-wheel drive with the differential locked. Select the appropriate switch position according to the terrain and the conditions. 4WD (four-wheel drive): power is supplied to

the front and rear wheels, with the front differen- tial unlocked.

LOCK (four-wheel drive with the differential gear locked): power is supplied to the front and rear wheels and the differential gear is locked. Unlike in four-wheel drive, all wheels turn at the same speed, giving maximum traction.

WARNING EWB00132

Always stop the ATV before changing from four-wheel drive to four-wheel-drive differen- tial gear lock or vice versa. The ATV handles differently in four-wheel drive than in differential gear lock in some circum- stances. Changing from four-wheel drive to differential gear lock or vice versa while mov- ing may cause the ATV to handle differently un- expectedly. This could distract the operator and increase the risk of losing control and causing an accident.

To access the 4WD/LOCK switch, set the 2WD/4WD switch to 4WD, and then move the drive switch lock lever to the right.

TIP When the switch is set to LOCK or 4WD, the

differential gear lock icon and indicator light will flash until the differential gear is completely locked or unlocked.

When the icon and indicator light are flashing, turning the handlebar back and forth will help the differential gear lock to engage or disen- gage.

Riding before the differential gear is properly en- gaged or disengaged (e.g., when the icon and indicator light are flashing) will cause the vehicle speed to be limited until the differential gear is completely engaged or disengaged.

When the ATV is in four-wheel-drive differential gear lock, the maximum traveling speed is limit- ed to 35 km/h (22 mi/h). However, if conditions require full engine power to be available, push and hold the override switch to disable the dif- ferential gear lock speed limiter. (See page 5-13.)

WARNING EWB00141

Always ride at a slow speed when the ATV is in differential gear lock, and allow extra time and distance for maneuvers. All wheels turn at the same speed when the dif- ferential gear is locked, so it takes more effort to turn the ATV. The effort needed to turn in- creases with the riding speed. You may lose control and have an accident if you cannot make a sharp enough turn for the speed you are traveling.

Accessories and loading

EBU20922

Genuine Yamaha Accessories Choosing accessories for your ATV is an impor- tant 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 connection to Yamaha manufacture parts and accessories or offer other modifications for Yamaha vehicles. Yamaha is not in a position to test the products that these aftermarket compa- nies produce. Therefore, Yamaha can neither en- dorse nor recommend the use of accessories not sold by Yamaha or modifications not specifically recommended by Yamaha, even if sold and in- stalled 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 po- tential safety hazards to you or others. Installing

aftermarket products or having other modifica- tions performed to your ATV that change any of the vehicles design or operation characteristics can put you and others at greater risk of serious injury or death. You are responsible for injuries re- lated 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 EWB00821

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.

Cargo or a trailer can change the stability and han- dling 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. Do not exceed the maximum tongue weight. You can measure tongue weight with a bath- room scale. Put the tongue of the loaded trailer on the scale with the tongue at hitch height. Ad- just the load in the trailer, if necessary, to reduce the weight on the hitch. If you are carrying cargo and towing a trailer, include the tongue weight in the maximum ATV load limit.

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

240.0 kg (530 lb) Front carrier:

50.0 kg (110 lb) Rear carrier:

90.0 kg (198 lb) Storage compartment:

4.0 kg (9 lb) Trailer hitch:

Pulling load (total weight of trailer and cargo):

5880 N (600 kgf, 1322 lbf) Tongue weight (vertical weight on trailer hitch point):

147 N (15 kgf, 33 lbf)

UB5K13E0.book Page 7 Thursday, August 19, 2021 2:35 PM

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 low range whenever you are carrying heavier loads or when towing a trailer.

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.

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. Shift to park position and follow the instruction on page 7-1 to start the engine. Once it has warmed up you are ready to begin riding your ATV. With the engine idling, shift the drive select lever into the low-range position or the high-range 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.

NOTICE ECB00252

Do not shift from low-range to high-range or vice versa without coming to a complete stop. Damage to the engine or drive train may occur.

TURNING YOUR ATV

WARNING EWB01772

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.

UB5K13E0.book Page 13 Thursday, August 19, 2021 2:35 PM

8-14

8

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 turn- ing 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. 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 direc- tion) 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 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.

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

8

Improper riding procedures such as abrupt throt- tle 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 be- gins to tip over to the outside while negotiating a turn, lean more to the inside. It may also be nec- essary 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

WARNING EWB01672

Climbing hills improperly can cause overturns or loss of control. Use proper riding techniques 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 exces- sively 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.

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.

UB5K13E0.book Page 16 Thursday, August 19, 2021 2:35 PM

8-17

8

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. For more traction and control for climbing steeper and/or rougher slopes, select 4WD or 4WD-LOCK (DIFF. LOCK) (YFM70KPAN / YFM70KPHN / YFM70KPSN). Travel fast enough to maintain momentum, 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 footboards and leaning forward over the handlebars. When- ever 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 remem- ber that some hills are too steep for you to climb or descend. 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 uphill side. Physically turn the ATV around and then descend the hill.

UB5K13E0.book Page 17 Thursday, August 19, 2021 2:35 PM

8

If you start to roll backwards, DO NOT apply either brake abruptly. If you are in 2WD, apply only the front brake. When fully stopped, apply the rear brake as well, and then shift to the park position. If you are in 4WD, because all wheels are inter- connected by the drive train, applying either brake will brake all wheels, therefore, avoid sudden ap- plication 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. When fully stopped, shift to the park position and dismount the ATV immediately on the uphill side. Dismount on 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. [EWB01803]

RIDING DOWNHILL

WARNING EWB01622

Going down a hill improperly could cause over- turns or loss of control. Always follow proper procedures for going down hills as described 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.

UB5K13E0.book Page 18 Thursday, August 19, 2021 2:35 PM

8-19

8

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. Apply brakes gradual- ly. If in 2WD, apply only the rear brake.

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. Engine compression will do most of the braking for you. For maximum engine com- pression braking effect, select the low-range posi- tion and change to 4WD before beginning to descend the hill. Use caution while descending a hill with loose or slippery surfaces. Braking ability and traction may be adversely affected by these surfaces. Improper braking may also cause a loss of traction. When this ATV is in 4WD, all wheels (front and rear) are interconnected by the drive train. This means that applying either the front brake or the

rear brake will brake all wheels. When descending hills, using either brake lever or the brake pedal will brake the wheels on the downhill side. Avoid sudden application of either the front or rear brake because the wheels on the uphill side could come off the ground. Apply both the front and rear brakes gradually. Whenever possible, ride your ATV straight 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 EWB01633

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, grad- ually steer again in the direction you wish to travel.

CROSSING THROUGH SHALLOW WATER

WARNING EWB01642

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 carefully.

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 without verifying that you have regained proper braking ability. WARNING! Wet brakes may have reduced stopping ability, which could cause loss of control. [EWB02622]

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. Also, remove the drain plugs from the storage compartment and the V- belt case to drain any water that may have accu- mulated. NOTICE: Undrained water can cause damage or improper operation.

RIDING OVER ROUGH TERRAIN

WARNING EWB01652

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 caution. Look out for obstacles which could cause damage to the ATV or could lead to an 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.

SLIDING AND SKIDDING

WARNING EWB01663

Skidding or sliding improperly may cause you to lose control of this ATV. You may also regain 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.

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 reduced. 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 footboard to the outside of the turn. Position your weight over the front wheels for better control. (See page 8-13.)

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 8-13.)

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 8-23.)

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 IF THE ATV IS IN 2WD the ATV may tip over on top of you. Dismount the ATV on the uphill side. (See page 8-16.)

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 8-20.)

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 8-21.)

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 ac- cordance with the periodic maintenance chart. In addition, the condition of the spark plug can reveal the condition of the engine.

To remove the spark plug 1. Remove panels A, C, and E. (See page 9-9.) 2. Remove the spark plug cap.

3. Remove the spark plug with a spark plug wrench as shown.

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 vehi- cle 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 vehicle.

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

3. Measure the spark plug gap with a wire thick- ness gauge and, if necessary, adjust the gap to specification.

To install the spark plug 1. Clean the surface of the spark plug gasket

and its mating surface, and then wipe off any grime from the spark plug threads.

2. Install the spark plug with the spark plug wrench, and then tighten it to the specified torque.

Why Yamalube YAMALUBE oil is a Genuine YAMAHA Part born of the engineers passion and belief that engine oil is an important liquid engine component. We form teams of specialists in the fields of mechanical en- gineering, chemistry, electronics and track test- ing, and have them develop the engine together with the oil it will use. Yamalube oils take full ad- vantage of the base oils qualities and blend in the ideal balance of additives to make sure the final oil clears our performance standards. Thus, Yamalube mineral, semisynthetic and synthetic oils have their own distinct characters and value.

Recommended oil: See page 11-1.

Oil quantity: Without oil filter cartridge replacement:

2.00 L (2.11 US qt, 1.76 Imp.qt) With oil filter cartridge replacement:

2.10 L (2.22 US qt, 1.85 Imp.qt)

Checking the brake fluid level Before riding, check that the brake fluid is above the minimum level mark. Replenish the brake fluid if necessary.

TIP Straighten the handlebars for an accurate reading.

NOTICE ECB01161

Brake fluid may damage painted surfaces or plastic parts. Always clean up spilled fluid im- mediately.

As the brake pads wear, it is normal for the brake fluid level to gradually go down. A low brake fluid level may indicate worn brake pads or brake sys- tem leakage. Therefore, be sure to check the brake pads for wear and the brake system for leakage. If the brake fluid level suddenly goes down, have a Yamaha dealer check the brake sys- tem before further riding.

WARNING EWB02721

Improper maintenance can result in loss of braking ability. Observe these precautions: Insufficient brake fluid may allow air to enter

the brake system, reducing braking perfor- mance.

Clean the filler cap before removing. Use only DOT 4 brake fluid from a sealed contain- er.

Use only the specified brake fluid; otherwise, the rubber seals may deteriorate, causing leakage.

Troubleshooting Although Yamaha ATVs receive a thorough in- spection before shipment from the factory, trouble may occur during operation. Any problem in the fuel, compression, or ignition systems, for exam- ple, can cause poor starting and loss of power. The following troubleshooting charts represent quick and easy procedures for checking these vi- tal systems yourself. However, should your ATV require any repair, take it to a Yamaha dealer, whose skilled technicians have the necessary tools, experience, 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.

WARNING EWB02281

Do not smoke when checking the fuel system. Fuel can ignite or explode, causing severe inju- ry or property damage. Make sure there are no open flames or sparks in the area, including pi- lot lights from water heaters or furnaces.

TIP Tap water can be used in an emergency. Change to the recommended coolant as soon as possible. The engine will tend to overheat if the radiator is caked with mud, or if the ATV is overloaded.

Wait until the engine has cooled.

Check the coolant level in the reservoir and radiator.

The coolant level is OK.

The coolant level is low. Check the cooling system for leakage.

Have a Yamaha dealer check and repair the cooling system.

Add coolant. (See TIP.)

CLEANING AND STORAGE EBU25883

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 degreaser to the wheel axles.

3. Rinse the dirt and degreaser off with a garden hose. Use only enough pressure to do the job. WARNING! Wet brakes may have re- duced stopping ability, increasing the chance of an accident. Test the brakes af- ter washing. Apply the brakes several times at slow speeds to let friction dry out the linings. [EWB02312] NOTICE: Excessive wa- ter pressure may cause water seepage

and deterioration of wheel bearings, brakes, transmission seals and electrical devices. Many expensive repair bills have resulted from improper high-pressure de- tergent applications such as those avail- able in coin-operated car washers. [ECB00712]

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 bottle brush is handy for hard-to-reach plac- es.

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

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 protec- tive finish. When finished cleaning, start the engine and let it idle for several minutes.

8. If the headlight lens has fogged up, start the engine and turn on the headlight to help re- move the moisture.

EBU27264

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. [ECB00722]

Long-term Before storing your ATV for several months:

1. Make any necessary repairs and perform all outstanding maintenance.

2. Follow all the instructions in the Cleaning sec- tion of this chapter.

3. Fill up the fuel tank and add fuel stabilizer (Fu- el Med Rx if available), and then run the en- gine for 5 minutes to distribute the treated fuel.

4. Perform the following steps to protect the en- gine from internal 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.

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

Specified amount: 7.5 ml per liter of fuel (1 oz per gallon)

6. Put the frame on stands or blocks to raise all wheels off the ground. (Alternatively, turn the wheels each month to prevent the tires from degrading in one spot.)

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

8. Remove the battery and fully charge it. (See page 9-53.)

WARRANTY QUESTIONS AND ANSWERS

Q. What costs are my responsibility during the warranty period? A. The customers responsibility includes all costs of normal maintenance services,

non-warranty repairs, accident and collision damages, and oil, oil filters, air filters, spark plugs, and brake shoes.

Q. What are some examples of abnormal strain, neglect, or abuse? A. These terms are general and overlap each other in areas. Specific examples include:

Running the machine out of oil, sustained high rpm, full-throttle, operating the machine with a broken or damaged part which causes another part to fail, damage or failure due to improper or careless transportation and or tie-down. If you have any specific questions on operation or maintenance, please contact your dealer for advice.

Q. Does the warranty cover incidental costs such as towing or transportation due to a failure?

A. No. The warranty is limited to repair of the machine itself.

Q. May I perform any or all of the recommended maintenance shown in the Owners Manual instead of having the dealer do them?

A. Yes, if you are a qualified mechanic and follow the procedures specified in the Owners and Service Manual. We do recommend, however, that items requiring special tools or equipment be done by a Yamaha ATV dealer.

Q. Will the warranty be void or cancelled if I do not operate or maintain my new ATV exactly as specified in the Owners Manual?

A. No. The warranty on a new ATV cannot be voided or cancelled. However, if a particular failure is caused by operation or maintenance other than as described in the Owners Manual, that failure may not be covered under warranty.

1. Completely set up every new machine before sale. 2. Explain the operation, maintenance, and warranty requirements to your satis-

faction at the time of sale, and upon your request at any later date. 3. Each Yamaha ATV dealer is held responsible for his setup, service and war-

ranty repair work.

Q. Is the warranty transferable to second owners? A. Yes. The remainder of the existing warranty can be transferred upon request. The

unit has to be inspected and re-registered by an authorized Yamaha ATV dealer for the policy to remain effective.
