EBU00209 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 operation or any condition which might result in excessive engine heating must be avoided. However, momentary (2 ~ 3 seconds maximum) full throttle operation under load does not harm the engine. Each full throttle acceleration sequence should be followed with a substantial rest period 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 period, consult a Yamaha dealer. 1. 0 ~ 10 hours: Avoid continuous operation above half throttle. Allow a cooling off period of five to ten minutes after every hour of operation. Vary the speed of the machine from time to time. Do not operate it at one set throttle position. 6-7 EBU00211 Parking When parking, stop the engine and shift into neutral. Turn the fuel cock to “OFF” and apply the parking brake. 2. 10 ~ 20 hours: Avoid prolonged operation above 3/4 throttle.

Riding on paved surfaces can cause loss of control. WARNING POTENTIAL HAZARD Operating this ATV on paved surfaces. WHAT CAN HAPPEN ATVs are designed for off-road use only. Paved surfaces may seriously affect handling and control of the ATV, and may cause the vehicle to go out of control. HOW TO AVOID THE HAZARD Always avoid paved surfaces, including sidewalks, driveways, parking lots and streets. 7-16 Do not ride on any public road, street, or highway. Riding on public roads can result in collisions with other vehicles. WARNING POTENTIAL HAZARD Operating this ATV on public streets, roads or highways. WHAT CAN HAPPEN You can collide with another vehicle. HOW TO AVOID THE HAZARD Never operate this ATV on any public street, road or highway, even a dirt or gravel one. In many states it is illegal to operate ATVs on public streets, roads and highways. 7-17 Know the terrain where you ride. Ride cautiously in unfamiliar areas. Stay alert for holes, rocks, or roots in the terrain, and other hidden hazards which may cause the machine to upset. WARNING POTENTIAL HAZARD Failure to use extra care when operating this ATV on unfamiliar terrain. WHAT CAN HAPPEN You can come upon hidden rocks, bumps, or holes, without enough time to react. Could result in the ATV overturning or going out of control. HOW TO AVOID THE HAZARD Go slowly and be extra careful when operating on unfamiliar terrain. Always be alert to changing terrain conditions when operating the ATV. 7-18 WARNING POTENTIAL HAZARD Failure to use extra care when operating on excessively rough, slippery or loose terrain. WHAT CAN HAPPEN Could cause loss of traction or vehicle control, which could result in an accident, including an overturn. HOW TO AVOID THE HAZARD Do not operate on excessively rough, slippery or loose terrain until you have learned and practiced the skills necessary to control the ATV on such terrain. Always be especially cautious on these kinds of terrain. 7-19 When riding in an area where you might not easily be seen, such as desert terrain, mount a caution flag on the machine. DO NOT use the flag pole bracket as a trailer hitch. WHAT CAN HAPPEN You could be in a collision. You could be injured. HOW TO AVOID THE HAZARD Always mount a caution flag on the machine to make you more visible. Watch carefully for other vehicles. Do not ride in areas posted “no trespassing”. Do not ride on private property without getting permission. WARNING POTENTIAL HAZARD Operating in areas where you might not be seen by other off-road vehicles. 7-20 Select a large, flat area off-road to become familiar with your ATV. Make sure that this area is free of obstacles and other riders. You should practice control of the throttle, brakes, shifting procedures, and turning techniques in this area before trying more difficult terrain. Always avoid riding on paved surfaces: the ATV is designed for off-road use only, and handling maneuvers are more difficult to perform on pavement. With the engine idling, lift the shift pedal to the 1st gear position and then release the parking brake. Apply the throttle slowly and smoothly. The centrifugal clutch will engage and you will start to accelerate. Once the ATV has attained adequate speed, release the throttle and lift the shift pedal to the 2nd gear position. Release the shift pedal and apply the throttle smoothly. Use this same procedure as you move into the higher gears. Be sure to coordinate the use of the throttle and shift pedal properly. 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 control. Avoid higher speeds until you are thoroughly familiar with the operation of your ATV. 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. Remember that the engine and exhaust pipe will be hot when riding and afterwards; do not allow skin or clothing to come in contact with these components. 7-21 WARNING CAUTION: Do not shift gears without releasing the throttle. Damage to the engine or drive train may occur. POTENTIAL HAZARD Engaging a lower gear when the engine speed is too high. When slowing down or stopping, release the throttle 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 control and increasing the possibility of an accident. WHAT CAN HAPPEN The wheels could stop rotating. This could cause loss of control, an accident and injury. It could also cause engine or drive train damage. HOW TO AVOID THE HAZARD Make sure the engine has sufficiently slowed before shifting to a lower gear. 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 inside of the turn is allowed to slip or lose some traction, the ATV will resist turning. A special turning technique must be used to allow the ATV to make turns quickly and easily. It is essential that this skill be learned first at low speed. HOW TO AVOID THE HAZARD Always follow proper procedures for turning as described in this Owner’s Manual. Practice turning at low speeds before attempting to turn at faster speeds. Do not turn at speeds too fast for your skills or the conditions. As you approach a curve, slow down and begin to turn the handlebars in the desired direction. As you do so, put your weight on the footboard to the outside of the turn (opposite your desired direction) and lean your upper body into the turn. Use the throttle to maintain an even speed through the turn. This maneuver will let the wheel on the inside of the turn slip slightly, allowing the ATV to make the turn properly. WARNING POTENTIAL HAZARD Turning improperly. WHAT CAN HAPPEN ATV could go out of control, causing a collision or overturn. 7-23 Once you have learned this technique you should be able to perform it at higher speeds or in tighter curves. This procedure should be practiced at slow speed many times in a large off-road area with no obstacles. If an incorrect technique is used, your ATV may continue to go straight. If the ATV doesn’t turn, come to a stop and then practice the procedure again. If the riding surface is slippery or loose, it may help to position more of your weight over the front wheels by moving forward on the seat. 7-24 Improper riding procedures such as abrupt throttle changes, excessive braking, incorrect body movements, or too much speed for the sharpness of the turn may cause the ATV to tip. If the ATV begins to tip over to the outside while negotiating a turn, lean more to the inside. It may also be necessary to gradually let off on the throttle and steer to the outside of the turn to avoid tipping over. Remember: Avoid higher speeds until you are thoroughly familiar with the operation of your ATV. CLIMBING UPHILL Use proper riding techniques to avoid vehicle overturns on hills. Be sure that you can maneuver your ATV well on flat ground before attempting any incline and then practice riding first on gentle slopes. Try more difficult climbs only after you have developed your skill. In all cases avoid inclines with slippery or loose surfaces, or obstacles that might cause you to lose control. HOW TO AVOID THE HAZARD Never operate the ATV on hills too steep for the ATV or for your abilities. Practice on smaller hills before attempting large hills. It is important when climbing a hill to make sure that your weight is transferred forward on the ATV. This can be accomplished by leaning forward and, on steeper inclines, standing on the footboards and leaning forward over the handlebars. WARNING POTENTIAL HAZARD Operating on excessively steep hills. WHAT CAN HAPPEN The vehicle can overturn more easily on extremely steep hills than on level surfaces or small hills. 7-25 WARNING An obstacle, a sharp drop, or another vehicle or person could be on the other side of the hill. POTENTIAL HAZARD Climbing hills improperly. WHAT CAN HAPPEN Could cause loss of control or cause the ATV to overturn. HOW TO AVOID THE HAZARD Always follow proper procedures for climbing hills as described in this Owner’s Manual. Always check the terrain carefully before you start up any hill. Never climb hills with excessively slippery or loose surfaces. Shift your weight forward. Never open the throttle suddenly or make sudden gear changes. The ATV could flip over backwards. Never go over the top of any hill at high speed. 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. When crossing the side of a hill: Always follow proper procedures as described in the Owner’s Manual. Avoid hills with excessively slippery or loose surfaces. Shift your weight to the uphill side of the ATV. WARNING POTENTIAL HAZARD Improperly crossing hills or turning on hills. WHAT CAN HAPPEN Could cause loss of control or cause 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. 7-27 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. WARNING POTENTIAL HAZARD Stalling, rolling backwards or improperly dismounting while climbing a hill. WHAT CAN HAPPEN Could result in ATV overturning. HOW TO AVOID THE HAZARD Use proper gear and maintain steady speed when climbing a hill. If you start to roll backwards, DO NOT use the rear brake to stop or try to put the ATV in gear. The ATV could easily tip over backwards. Instead, dismount the ATV immediately on the uphill side. If you lose all forward speed: Keep weight uphill. Apply the brakes. Lock parking brake, after you are stopped. If you begin rolling backwards: Keep weight uphill. Never apply the rear brake while rolling backwards. Apply the front brake. When fully stopped, apply rear brake as well, and then lock parking brake. 7-28 Dismount on uphill side or to a side if pointed straight uphill. Turn the ATV around and remount, following the procedure described in the Owner’s Manual. 7-29 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. Choose a low gear which will allow the engine compression to do most of the braking for you. 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. WARNING POTENTIAL HAZARD Going down a hill improperly. WHAT CAN HAPPEN Could cause loss of control or cause ATV to overturn. HOW TO AVOID THE HAZARD Always follow proper procedures for going down hills as described in this Owner’s Manual. Note: a special technique is required when braking as you go down a hill. Always check the terrain carefully before you start down any hill. Shift your weight backward. Never go down a hill at high speed. Avoid going down a hill at an angle that would cause the vehicle to lean sharply to one side. Go straight down the hill where possible. Whenever possible, ride your ATV straight downhill. Avoid sharp angles which could allow the ATV to tip or roll over. Carefully choose your path and ride no faster than you will be able to react to obstacles which may appear. 7-30 7-31 CROSSING A SLOPE Traversing a sloping surface on your ATV requires you to properly position your weight to maintain proper balance. Be sure that you have learned the basic riding skills on flat ground before attempting to cross a sloping surface. Avoid slopes with slippery surfaces or rough terrain that may upset your balance. 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. 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. WHAT CAN HAPPEN Could cause loss of control or cause ATV to overturn. WARNING POTENTIAL HAZARD Improperly crossing hills or turning on hills. 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. 7-32 When crossing the side of a hill: Always follow proper procedures as described in the Owner’s Manual. Avoid hills with excessively slippery or loose surfaces. Shift your weight to the uphill side of the ATV. 7-33 CROSSING THROUGH SHALLOW WATER The ATV can be used to cross slow moving, shallow water of up to a maximum of 35 cm (14 inches) 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. 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. WARNING POTENTIAL HAZARD Operating this ATV through deep or fast flowing water. WHAT CAN HAPPEN Tires may float, causing loss of traction and loss of control, which could lead to an accident. HOW TO AVOID THE HAZARD Never operate this ATV in fast flowing water or in water deeper than that specified in your Owner’s Manual. 7-34 Test your brakes after leaving the water. Do not continue to ride your ATV without verifying that you have regained proper braking ability. CAUTION: 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. Wash the ATV in fresh water if it has been operated in salt water or muddy conditions. 1 1. Check hose 7-35 RIDING OVER ROUGH TERRAIN 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. WARNING POTENTIAL HAZARD Improperly operating over obstacles. WHAT CAN HAPPEN Could cause loss of control or a collision. 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 obstacles, such as large rocks or fallen trees. When you go over obstacles, always follow proper procedures as described in the Owner’s Manual. 7-36 7-37 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. If the rear wheels of your ATV start to slide sideways, control can usually be regained (if there is room to do so) by steering in the direction of the slide. Applying the brakes or accelerating is not recommended until you have corrected the slide. To reduce the tendency for the front wheels to slide in loose or slippery conditions, positioning your weight over the front wheels will sometimes help. 7-38 With practice, over a period of time, skill at controlled sliding can be developed. The terrain should be chosen carefully before attempting such maneuvers, since both stability and control are reduced. Bear in mind that sliding maneuvers should always be avoided on extremely slippery surfaces such as ice, since all control may be lost. 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 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. 7-39 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 7-23 ~ 7-24.) ● 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 pages 7-23 ~ 7-24.) ● 7-40 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 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 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 pages 7-25 ~ 7-29.) ● ● If your ATV is traversing a sloping surface: Be sure to ride with your weight positioned towards the uphill side of the ATV to maintain proper balance. If the ATV starts to tip, steer down the hill (if there are no obstacles in your way) to regain balance. If you discover that the ATV is going to tip over, dismount on the uphill side. (See 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 until you have regained adequate braking ability. (See pages 7-34 ~ 7-35.)

EBU00419 CLEANING AND STORAGE CAUTION: Excessive water 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 detergent applications such as those available in coin-operated car washers. 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 to do the job. 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. 9-1 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 cleanerwaxes. 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 washing. 8 WHAT CAN HAPPEN Wet brakes may have reduced stopping ability, increasing the chance of an accident. 8 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. 8 8 8 8 8 8 9 80 88 88 88 88 9-2 EBU00530 B. STORAGE Long term storage (60 days or more) of your machine will require some preventive procedures 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 equivalent product. 2. Remove the spark plug, pour about one tablespoon of SAE 10W30 or 20W40 motor oil in the spark plug hole and reinstall the spark plug. Ground the spark plug wire and turn the engine over several 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 atmosphere, 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) NOTE: Use of fuel stabilizer and conditioner eliminates the need to drain the fuel system. Consult a Yamaha dealer if the fuel system needs to be drained instead. 9-3 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 excessively warm or cold place (less than 0˚C (30˚F) or more than 30˚C (90˚F)).

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 shown in the Owner’s Manual, that failure may not be covered under warranty. If you should move after you have purchased your new ATV, please advise us of your new address by sending a postcard listing your ATV model name, V.I.N. (frame number), dealer number (or dealer’s name) as it is shown on your warranty card, your name and new mailing address. Mail to: Q. What responsibility does my dealer have under this warranty? A. Each Yamaha ATV dealer is expected to: 1. Completely set up every new machine before sale. 2. Explain the operation, maintenance, and warranty requirements to your satisfaction 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 warranty repair work. YAMAHA MOTOR CORPORATION, U.S.A. P.O. Box 6555 Cypress, California 90630 Attention: Warranty Department This will ensure that Yamaha Motor Corporation, U.S.A. has an up-to-date registration record in accordance with federal law. Q.
