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 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 or pulling a trailer. Allow greater distance for braking.

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 U5TE10.book Page 8 Wednesday, April 10, 2002 10:32 AM EBU00211 Parking When parking, stop the engine and shift into neutral.

If you must park on an incline, place the machine transversely across the incline, apply the parking brake, and block the front and rear wheels with rocks or other objects. Do not park the ATV at all on hills that are so steep you could not walk up them easily. 6-9 U5TE10.book Page 10 Wednesday, April 10, 2002 10:32 AM EBU00221 Accessories and loading ● EBU00222 Accessories Accessories can affect the handling and control of your ATV. Keep the following in mind when considering an accessory or operating an ATV which has accessories. ● Choose only accessories designed for your ATV. Your Yamaha dealer has a variety of genuine Yamaha accessories. Other accessories may also be available on the market. However, it is not possible for Yamaha to test all non-Yamaha accessories, nor have any control over the quality or suitability of them. Choose a genuine Yamaha accessory, or one that is equivalent in design and quality. ● ● 6-10 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 interfere with your ability to control the ATV. Examples 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 accessories. The ATV may handle differently than it does without accessories. U5TE10.book Page 11 Wednesday, April 10, 2002 10:32 AM EBU00960 Loading Cargo or a trailer can change the stability and handling 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 overloaded ATV can be unstable. ● MAXIMUM LOADING LIMIT ● Vehicle loading limit (total weight of cargo, rider and accessories, and tongue weight): 210 kg (463 lb) ● Front carrier: 40 kg (88 lb) ● Rear carrier: 80 kg (176 lb) ● Storage box: 2.0 kg (4.4 lb) ● Trailer hitch: Pulling load (total weight of trailer and cargo): 500 kgf (1,102 lbf) Tongue weight (vertical weight on trailer hitch point): 15 kgf (33 lbf) ● ● ● 6-11 Do not exceed the maximum tongue weight. You can measure tongue weight with a bathroom scale. Put the tongue of the loaded trailer on the scale with the tongue at hitch height. Adjust the load in the trailer, if necessary, to reduce the weight on hitch. If you are carrying cargo and towing a trailer, include the tongue weight in the maximum vehicle load limit. Load cargo on the carrier as close to the center of the vehicle as possible. Put cargo at the front of the rear carrier. Center the load from side to side. 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 controls or your ability to see where you are going. U5TE10.book Page 12 Wednesday, April 10, 2002 10:32 AM ● ● ● ● 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 vehicle 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. WARNING POTENTIAL HAZARD Overloading this ATV or carrying or towing cargo improperly. WHAT CAN HAPPEN Could cause changes in vehicle handling which could lead to an accident. HOW TO AVOID THE HAZARD Never exceed the stated load capacity for this ATV.

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 U5TE10.book Page 20 Wednesday, April 10, 2002 10:32 AM When riding in an area where you might not easily be seen, such as desert terrain, mount a caution flag on the ATV. 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 ATV 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 U5TE10.book Page 21 Wednesday, April 10, 2002 10:32 AM 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. With the engine idling, shift the drive select lever into the forward “FWD” 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. 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 hot when riding and afterwards; do not allow skin or clothing to come in contact with these components. 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. 7-21 U5TE10.book Page 22 Wednesday, April 10, 2002 10:32 AM TURNING YOUR ATV To achieve maximum traction while riding offroad, 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. 7-22 U5TE10.book Page 23 Wednesday, April 10, 2002 10:32 AM Once you have learned this technique you should be able to perform it at higher speeds or in tighter curves. Improper riding procedures such as abrupt throttle changes, excessive braking, incorrect body 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. 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. 7-23 U5TE10.book Page 24 Wednesday, April 10, 2002 10:32 AM 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. 7-24 U5TE10.book Page 25 Wednesday, April 10, 2002 10:32 AM 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. The ATV could flip over backwards. Never go over the top of any hill at high speed. 7-25 U5TE10.book Page 26 Wednesday, April 10, 2002 10:32 AM 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. WARNING 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. 7-26 U5TE10.book Page 27 Wednesday, April 10, 2002 10:32 AM 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. 7-27 U5TE10.book Page 28 Wednesday, April 10, 2002 10:32 AM and rear brakes gradually, or dismount the ATV immediately on the uphill side. 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 Maintain 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. If you start to roll backwards, DO NOT apply either brake abruptly. If you are in 2WD, apply only the front brake. 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. The ATV could easily tip over backwards. Apply both the front 7-28 U5TE10.book Page 29 Wednesday, April 10, 2002 10:32 AM If you begin rolling backwards: Keep weight uphill. 2WD: Never apply the rear brake while rolling backwards. Apply the front brake. 4WD: Apply both front and rear brakes gradually. When fully stopped, apply 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. 7-29 U5TE10.book Page 30 Wednesday, April 10, 2002 10:32 AM 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. Engine compression will do most of the braking for you. For maximum engine compression braking effect, change to 4WD before beginning to descend the hill. 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. 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 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 U5TE10.book Page 31 Wednesday, April 10, 2002 10:32 AM WARNING POTENTIAL HAZARD Going down a hill improperly. WHAT CAN HAPPEN Could cause loss of control or cause the ATV to overturn. 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. HOW TO AVOID THE HAZARD 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. 7-31 U5TE10.book Page 32 Wednesday, April 10, 2002 10:32 AM 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. WARNING 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. 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. 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. 7-32 U5TE10.book Page 33 Wednesday, April 10, 2002 10:32 AM 7-33 U5TE10.book Page 34 Wednesday, April 10, 2002 10:32 AM 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 U5TE10.book Page 35 Wednesday, April 10, 2002 10:32 AM 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 and the check hose on the V-belt cooling duct. Wash the ATV in fresh water if it has been operated in salt water or muddy conditions. _ 1. Air filter case check hose 7-35 U5TE10.book Page 36 Wednesday, April 10, 2002 10:32 AM 1.

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. 7-37 U5TE10.book Page 38 Wednesday, April 10, 2002 10:32 AM 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 U5TE10.book Page 39 Wednesday, April 10, 2002 10:32 AM 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 U5TE10.book Page 40 Wednesday, April 10, 2002 10:32 AM 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 7-22–7-23.) ● 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 7-22–7-23.) ● 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 7-24–7-29.) U5TE10.book Page 41 Wednesday, April 10, 2002 10:32 AM ● ● 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.

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 U5TE10.book Page 2 Wednesday, April 10, 2002 10:32 AM 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, start the engine and let it idle for several minutes. WARNING POTENTIAL HAZARD Operation with wet brakes after washing. WHAT CAN HAPPEN Wet brakes may have reduced stopping ability, increasing the chance of an accident. 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. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 9-2 U5TE10.book Page 3 Wednesday, April 10, 2002 10:32 AM 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 U5TE10.book Page 4 Wednesday, April 10, 2002 10:32 AM 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)).
