ECB00230 NOTICE Do not shift gears without releasing the throttle. Damage to the engine or drive train may occur. 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. 7-16 EWB01070 EWB01220 WARNING WARNING POTENTIAL HAZARD Engaging a lower gear when the engine speed is too high. 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. 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. 7-17 POTENTIAL HAZARD Turning improperly. WHAT CAN HAPPEN The 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 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. 8 2 3 4 5 6 7 9 10 11 curves. Improper riding procedures such as abrupt throttle changes, excessive braking, incorrect body movements, or too much speed for the sharpness of the turn may cause the ATV to tip. If the ATV begins to tip over to the outside while negotiating a turn, lean more to the 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. 1 2 3 4 5 6 7 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.

Lean towards inside of turn. 2. Support your weight on the outer footrest. 8 9 10 11 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 EWB01090 WARNING POTENTIAL HAZARD Operating on excessively steep hills. 7-18 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. 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. An obstacle, a sharp drop, or another vehicle or person could be on the other side of the hill. 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.

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. 1 2 3 4 5 6 7 8 9 10 11 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 7-17.) ● If your ATV begins to tip while turning: EWB01170 WARNING POTENTIAL HAZARD Skidding or sliding improperly. 7-28 ● ● ● ● 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 page 7-24.) 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 7-17.) If your ATV starts to slide sideways: Steer in the direction of the slide if you have the room. Applying the brakes or accelerating is not recommended until you have corrected the slide. (See page 7-27.) 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 page 7-18.) 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 page 7-23.)

Install panel E. 1 EBU29440 2 The spark plug is an important engine component, which should be checked periodically, preferably by a Yamaha dealer. Since heat and deposits will cause any spark plug to slowly erode, the spark plug should be removed and checked in accordance with the periodic maintenance and lubrication chart. In addition, the condition of the spark plug can reveal the condition of the engine. The porcelain insulator around the center electrode of the spark plug should be a medium-to-light tan (the ideal color when the vehicle is ridden normally). If the spark plug shows a distinctly different color, the engine could be operating improperly. Do not attempt to diagnose such problems yourself. Instead, have a Yamaha dealer check the vehicle. If a spark plug shows signs of electrode erosion and excessive carbon or other deposits, it should be replaced. 3 4 5 6 7 8 9 10 11 Checking the spark plug 1.

Give notice to an authorized Yamaha ATV dealer of any and all apparent defects within ten (10) days after discovery, and make the machine available at that time for inspection and repairs at such dealer’s place of business. WARRANTY TRANSFER: To transfer the warranty from the original purchaser to any subsequent purchaser(s), it is imperative that the machine be inspected and registered for warranty by an authorized Yamaha ATV dealer. In order for this warranty to remain in effect, this inspection and registration must take place within ten (10) days after transfer. An inspection and registration fee will be charged for this service. EMISSION CONTROL SYSTEM WARRANTY Yamaha Motor Corporation, USA also warrants to the ultimate purchaser and each subsequent purchaser of each 2006 and later model Yamaha ATV covered by this warranty that the vehicle is designed, built, and equipped so as to conform at the time of sale with all U.S. emissions standards applicable at the time of manufacture and that it is free from defects in materials and workmanship which would cause it not to meet these standards 11-5 within the period listed immediately below.

The customer’s 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. If your machine requires warranty service, you must take it to any authorized Yamaha ATV dealer within the continental United States. Be sure to bring your warranty registration card or other valid proof of the original date of purchase. If a question or problem arises regarding warranty, first contact the owner of the dealership. Since all warranty matters are handled at the dealer level, this person is in the best position to help you. If you are still not satisfied and require additional assistance, please write: 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. YAMAHA MOTOR CORPORATION U.S.A. CUSTOMER RELATIONS DEPARTMENT P.O. Box 6555 Cypress, California 90630 When contacting Yamaha Motor Corporation, U.S.A. don’t forget to include any important information such as names, addresses, model, V.I.N. (frame number), dates, and receipts. 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. CHANGE OF ADDRESS Q. May I perform any or all of the recommended maintenance shown in the Owner’s Manual instead of having the dealer do them? A. Yes, if you are a qualified mechanic and follow the procedures specified in the Owner’s and Service Manual. We do recommend, however, that items requiring special tools or equipment be done by a Yamaha ATV dealer. The federal government requires each manufacturer of a motor vehicle to maintain a complete, up-to-date list of all first purchasers against the possibility of a safety-related defect and recall. This list is compiled from the purchase registrations sent to Yamaha Motor Corporation, U.S.A. by the selling dealer at the time of your purchase. Q. Will the warranty be void or cancelled if I do not operate or maintain my new ATV exactly as specified in the Owner’s 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 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. 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 EBU26122 YAMAHA EXTENDED SERVICE (Y.E.S.) 1 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. 2 3 4 5 6 7 8 9 10 11 11-7 1 2 3 4 5 6 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.
