SEVERE INJURY OR DEATH can result if you do not follow these instructions: ● Read this manual and all labels carefully and follow the operating procedures described. ● Never operate an ATV without proper training or instruction. Take a Training Course. Beginners should receive training from a certified instructor. Contact an authorized ATV dealer or call 1800-887-2887 to find out about the training courses nearest you. ● Always follow the age recommendation: – A child under 16 years old should never operate an ATV with engine size greater than 90 cc. ● ● ● ● ● ● ● 1-1 Never allow a child under age 16 to operate an ATV without adult supervision, and never allow continued use of an ATV by a child if he or she does not have the abilities to operate it safely. Never carry a passenger on an ATV. Always avoid operating an ATV on any paved surfaces, including sidewalks, driveways, parking lots and streets. Never operate an ATV on any public street, road or highway, even a dirt or gravel one. Never operate an ATV without wearing an approved motorcycle helmet that fits properly. You should also wear eye protection (goggles or face shield), gloves, boots, a long-sleeved shirt or a jacket, and long pants. Never consume alcohol or drugs before or while operating this ATV. Never operate at speeds too fast for your skills or the riding conditions. Always go at a speed that is proper for the terrain, visibility, operating conditions, and your experience. Never attempt wheelies, jumps, or other stunts. 1 U3D513E0.book Page 2 Monday, May 19, 2008 3:19 PM ● 1 ● ● ● ● ● ● Always inspect your ATV each time you use it to make sure it is in safe operating condition. Always 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 operating on unfamiliar terrain. Always be alert to changing terrain conditions when operating the ATV. Never operate on excessively rough, slippery or loose terrain until you have learned and practiced 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. ● ● ● 1-2 Always follow proper procedures for climbing hills as described in this manual. Check the terrain carefully before you start up any hill. Never climb hills with excessively slippery or loose surfaces. Shift your weight forward. Never open the throttle suddenly. Never go over the top of a hill at high speed. Always follow proper procedures for going down hills and for braking on hills as described in this manual. Check the terrain carefully before you start down any hill. Shift your weight backward. Never go down a hill at high speed. Avoid going down a hill at an angle that would cause the vehicle to lean sharply to one side. Go straight down the hill where possible.

Never attempt to operate over large obstacles, such as large rocks or fallen trees. Always follow proper procedures when operating over obstacles as described in this manual. Always be careful when skidding or sliding. Learn to safely control skidding or sliding by practicing at low speeds and on level, smooth terrain. On extremely slippery surfaces, such as ice, go slowly and be very cautious in order to reduce the chance of skidding or sliding out of control. Never operate an ATV in fast flowing water or in water deeper than that recommended in this manual. Remember that wet brakes may have reduced stopping ability. Test your brakes after leaving water. If necessary, apply them several times to let friction dry out the linings. Always be sure there are no obstacles or people behind you when you operate in reverse. When it is safe to proceed in reverse, go slowly. ● Always use the size and type of tires specified in this manual. ● Always maintain proper tire pressure as described in this manual. ● Never modify an ATV through improper installation or use of accessories. ● Never exceed the stated load capacity for an ATV. Cargo should be properly distributed and securely attached. Reduce speed and follow instructions in this manual for carrying cargo. Allow greater distance for braking.

With the engine idling, return the starter (choke) to the closed position and shift the drive select lever into the forward position, then release the parking brake. Apply the throttle slowly and smoothly. The centrifugal clutch will engage and you will start to accelerate. If the throttle is applied too abruptly, the front wheels may lift off the ground, resulting in a loss of directional control. Avoid higher speeds until you are thoroughly familiar with the operation of your ATV. When slowing down or stopping, release the throttle and apply the brakes smoothly and evenly. Improper use of the brakes can cause the tires to lose traction, reducing control and increasing the possibility of an accident. Do not ride in areas posted “no trespassing”. Do not ride on private property without getting permission. 7 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, and turning techniques in this area before trying more difficult terrain. Always avoid riding on paved surfaces: the ATV is designed for off-road use only, and handling maneuvers are more difficult to perform on pavement. Set the parking brake and follow the instruction on page 6-1 to start the engine. Once it has warmed up you are ready to begin riding your ATV. Remember that the engine and exhaust pipe will be 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 7-16 U3D513E0.book Page 17 Monday, May 19, 2008 3:19 PM used to allow the ATV to make turns quickly and easily. It is essential that this skill be learned first at low speed. EWB01080 WARNING POTENTIAL HAZARD Turning improperly. WHAT CAN HAPPEN ATV could go out of control, causing a collision or overturn. HOW TO AVOID THE HAZARD Always follow proper procedures for turning as described in this Owner’s Manual. Practice turning at low speeds before attempting to turn at faster speeds. Do not turn at speeds too fast for your skills or the conditions. 1. Lean towards inside of turn. 2. Support your weight on the outer footboard. This procedure should be practiced at slow speed many times in a large off-road area with no obstacles. If an incorrect technique is used, your ATV may continue to go straight. If the ATV doesn’t turn, come to a stop and then practice the procedure again. If the riding surface is slippery or loose, it may help to position more of your weight over the front wheels by moving forward on the seat. Once you have learned this technique, you should be able to perform it at higher speeds or in tighter curves. As you approach a curve, slow down and begin to turn the handlebars in the desired direction. As you do so, put your weight on the footboard to the outside of the turn (opposite your desired direction) and lean your upper body into the turn. Use the throttle to maintain an even speed through the turn. This maneuver will let the wheel on the inside of the turn slip slightly, allowing the ATV to make the turn properly. 7-17 7 U3D513E0.book Page 18 Monday, May 19, 2008 3:19 PM 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. 7 WHAT CAN HAPPEN The ATV can overturn more easily on extremely steep hills than on level surfaces or small hills. HOW TO AVOID THE HAZARD Never operate the ATV on hills too steep for the ATV or for your abilities. Practice on smaller hills before attempting large hills. 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. CLIMBING UPHILL Use proper riding techniques to avoid ATV overturns on hills. Be sure that you can maneuver your ATV well on flat ground before attempting any incline and then practice riding first on gentle slopes. Try more difficult climbs only after you have developed your skill. In all cases avoid inclines with slippery or loose surfaces, or obstacles that might cause you to lose control. EWB01180 WARNING POTENTIAL HAZARD Climbing hills improperly. WHAT CAN HAPPEN Could cause loss of control or cause the ATV to overturn. EWB01090 WARNING POTENTIAL HAZARD Operating on excessively steep hills. 7-18 U3D513E0.book Page 19 Monday, May 19, 2008 3:19 PM 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. 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. 7 7-19 U3D513E0.book Page 20 Monday, May 19, 2008 3:19 PM 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. EWB01190 WARNING 7 POTENTIAL HAZARD Improperly crossing hills or turning on hills. WHAT CAN HAPPEN Could cause loss of control or cause the ATV to overturn. HOW TO AVOID THE HAZARD Never attempt to turn the ATV around on any hill until you have mastered the turning technique as described in the Owner’s Manual on level ground. Be very careful when turning on any hill. Avoid crossing the side of a steep hill if possible. 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. 7-20 U3D513E0.book Page 21 Monday, May 19, 2008 3:19 PM If you start to roll backwards, DO NOT apply the rear brake to stop or try to put the ATV in gear. The ATV could easily tip over backwards. Instead, apply the front brake gradually, or dismount the ATV immediately on the uphill side. If you begin rolling backwards: ● Keep weight uphill. ● Never apply the rear brake while rolling backwards. Apply the front brake. ● When fully stopped, apply the rear brake as well, and then lock the parking brake. 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. EWB01261 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 Maintain a steady speed when climbing a hill. If you lose all forward speed: ● Keep weight uphill. ● Apply the brakes. ● Apply the parking brake after you are stopped. 7 7-21 U3D513E0.book Page 22 Monday, May 19, 2008 3:19 PM 7 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. 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. 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. 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 ATV to lean sharply to one side. Go straight down the hill where possible. EWB01130 WARNING POTENTIAL HAZARD Going down a hill improperly. WHAT CAN HAPPEN Could cause loss of control or cause the ATV to overturn. 7-22 U3D513E0.book Page 23 Monday, May 19, 2008 3:19 PM 7 7-23 U3D513E0.book Page 24 Monday, May 19, 2008 3:19 PM 7 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. 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. 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. When crossing the side of a hill: Always follow proper procedures as described in the Owner’s Manual.

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. 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. SLIDING AND SKIDDING Care should be used when riding on loose or slippery surfaces since the ATV may slide. If unexpected and uncorrected, sliding could lead to an accident. To reduce the tendency for the front wheels to slide in loose or slippery conditions, positioning your weight over the front wheels will sometimes help. 7-29 7 U3D513E0.book Page 30 Monday, May 19, 2008 3:19 PM 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 WHAT TO DO IF... This section is designed to be a reference guide only. Be sure to read each section on riding techniques completely. 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. 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 page 7-16.)

EBU25870 Cleaning 9 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. 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 places. 5. Rinse the ATV off immediately with clean water 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 protective finish. When finished cleaning, start the engine and let it idle for several minutes.

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. 11-6 U3D513E0.book Page 7 Monday, May 19, 2008 3:19 PM EBU26122 YAMAHA EXTENDED SERVICE (Y.E.S.) Keep your Yamaha protected even after your warranty expires with genuine Yamaha Extended Ser vice (Y.E.S.). In addition, Travel and Recreation Interruption Protection (TRIP) is included at no extra cost. 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. is designed and administered by Yamaha Motor Corporation to provide maximum owner satisfaction. You get uninterrupted factor y-backed coverage for extra peace of mind. Y. E. S. is flexible. You choose the plan that’s right for you: 12 months, 24 months, or 36 months beyond your warranty period. Y.E.S. coverage is honored at any authorized Yamaha dealer nationwide. Y.E.S. is designed and administered by the same Yamaha people who handle your warranty – and it shows in the comprehensive coverage benefits. There are no mileage limitations. Coverage isn’t limited to “moving par ts” or the “drive train” like many other plans. And Y.E.S. covers manufacturing defects just like the warranty. See the sample contract at your Yamaha dealer to see how comfor ting uninterr upted factor ybacked protection can be. 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. You don’t have to pay anything for covered repairs. T h e r e ’s n o d e d u c t i b l e t o p ay, a n d r e p a i r s a r e n ’ t “pro-rated.” You don’t have any “out-of-pocket” expenses for covered repairs. 11 11-7 U3D513E0.book Page 8 Monday, May 19, 2008 3:19 PM We urge you to act now. You’ll get the excellent benefits of TRIP coverage right away, and you’ll rest easy knowing you’ll have strong factory-backed protection even after your Yamaha Limited Warranty expires. You can also save money: Y.E.S. costs less within the first 90 days after you buy your Yamaha. See your dealer today! A special note: If visiting your dealer isn’t convenient, contact Yamaha with your Primar y ID number (your frame number). We’ll be happy to help you get the Y.E.S. coverage you need.
