q SAFETY INFORMATION	2

AN ATV IS NOT A TOY AND CAN BE HAZARDOUS TO OPERATE.

An ATV handles differently from other vehicles including motorcycles and cars. A collision or rollover can occur quickly, even during routine maneuvers such as turning and riding on hills or over obstacles, if you fail to take proper precautions.

SEVERE INJURY OR DEATH can result if you do not follow these instructions:

8Read this manual and all labels carefully and follow the operating procedures described.

8Never 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 1-800-887-2887 to find out about the training courses nearest you.

8Always follow the age recommendation:

-A child under 6 years old should never operate an ATV with engine size greater than 50cc.

-A child under 12 years old should never operate an ATV with engine size greater than 70cc.

-A child under 16 years old should never operate an ATV with engine size greater than 90cc.

8Never 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.

8Never carry a passenger on an ATV.

2-1

8Always avoid operating an ATV on any paved surfaces, including sidewalks, driveways, parking lots and streets.

8Never operate an ATV on any public street, road or highway, even a dirt or gravel one.

8Never operate an ATV without wearing an approved motorcycle helmet that fits properly. You should also wear eye protection (goggles or face shield), gloves, boots, long-sleeved shirt or jacket, and long pants.

8Never consume alcohol or drugs before or while operating this ATV.

8Never operate at speeds too fast for your skills or the conditions. Always go at a speed that is proper for the terrain, visibility and operating conditions, and your experience.

8Never attempt wheelies, jumps, or other stunts.

8Always 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.

8Always keep both hands on the handlebars and both feet on the footrests of the ATV during operation.

8Always go slowly and be extra careful when operating on unfamiliar terrain. Always be alert to changing terrain conditions when operating the ATV.

8Never 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.

2-2

8Always follow proper procedures for turning as described in this manual. Practice turning at low speeds before attempting to turn at faster speeds. Do not turn at excessive speed.

8Never operate the ATV on hills too steep for the ATV or for your abilities. Practice on smaller hills before attempting larger hills.

8Always 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 or make sudden gear changes. Never go over the top of a hill at high speed.

8Always 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.

8Always 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.

8Always use proper procedures if you stall or roll backwards when climbing a hill. If you stall or roll backwards, follow the special procedure for braking described in this manual. Instead, apply the front brake or dismount on the uphill side or to a side if pointed straight uphill. Turn the ATV around and remount, following the procedure described in this manual.

2-3

8Always 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 obstacles as described in this manual.

8Always 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.

8Never 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.

8Always use the size and type tires specified in this manual. Always maintain proper tire pressure as described in this manual.

8Never modify an ATV through improper installation or use of accessories.

8Never 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 MORE INFORMATION ABOUT ATV SAFETY, call the Consumer Products Safety Commission at 1-800-638-2772, or the ATV Distributor’s Safety Hotline at 1-800-852-5344.

2-4

TEACHING YOUR CHILD TO OPERATE THE ATV

qWARNING

POTENTIAL HAZARD

Allowing a child under 16 to operate this ATV without adult supervision (a child under 6 should not ride this ATV even with adult supervision).

WHAT CAN HAPPEN

If the child rides beyond his or her abilities, or rides in terrain that is too difficult, he or she may lose control of the ATV, causing an accident.

HOW TO AVOID THE HAZARD

Never let your child ride an ATV without close adult supervision. Promptly correct your child if he or she begins to ride beyond his or her abilities and, if necessary, intervene by pulling the cord (lanyard) to stop the engine.

Introduce new riding areas slowly and make sure the riding area matches your child’s skill level.

You must make the commitment to your child’s proper use of the ATV. Your child must rely upon you to be sure he or she has the development, proper training, and proper equipment, as well as an appropriately sized ATV and an appropriate riding area.

Be sure your child is ready to learn how to ride

As a parent, your first step is to decide when your child has the strength, skills, and judgment to learn how to operate an ATV safely. To help you make that decision, the ATV Safety Institute publishes a readiness checklist. It is printed in the Parents, Youngsters and ATVs booklet that was included with your ATV when newly purchased.

2-5

You can also review the checklist on the Internet at www.atvsafety.org. Re-evaluate your child’s readiness before every use; a child who is too tired or distracted should not be allowed to operate the ATV.

Be sure your child is properly trained

Your child should take a certified training course, like the ATV RiderCourse offered by the ATV Safety Institute. Call ATV Enrollment Express toll-free at 1-800-887-2887 for more information. Training will continue with you as the instructor, so you should be sure you thoroughly understand proper riding techniques before continuing to instruct your child. Go through this Owner’s Manual and the Parents, Youngsters and ATVs booklet page by page with your child and be sure he or she understands how to operate the ATV properly.

Be sure your child is wearing all the proper safety equipment

Your child must always wear an approved motorcycle helmet that fits properly. Your child should also wear the safety equipment described in the Riding Your ATV section of this manual.

Choose an appropriate riding area

Select an area appropriate for your child to learn to ride. (See page 7-16.) Follow the instructions in the Riding Your ATV section of this manual. Choose a large, flat off-road area that is free of obstacles and away from other vehicles.

Supervise every use of the ATV

Because an adult must supervise every ATV operator under age 16, you should closely watch your child every time he or she uses the ATV. Be ready to intervene immediately if the child is not operating according to your guidelines. This ATV is fitted with an engine stop switch cord (lanyard) device that will let you stop the engine

2-6 remotely as you walk behind the vehicle.

ENGINE STOP SWITCH CORD

This model has an engine stop switch cord (lanyard) designed for use by an adult supervising the child operating the ATV. When using the engine stop switch cord, be sure the speed limiter on the handlebar is adjusted to limit the ATV to a walking speed. (See page 4-6.)

1.Push the clip on the end of the engine stop switch cord under the engine shut-off switch (black button).

2.Put your fingers in the loop at the other end of the cord.

3.As your child is riding, walk behind the ATV, closely watching his or her actions as well as the path ahead.

4.If there is a potential hazard ahead or if your child is not riding correctly, pull firmly on the cord to stop the engine.

Because the ATV will continue to roll for some distance, allow extra time and distance to pull the cord before a potentially hazardous situation might be encountered.

When your child has developed sufficient skill to no longer need you to follow with the cord, the cord can be stowed under the seat of the ATV. However, you must still closely supervise your child at all times during ATV operation.

NOTE:

The ATV will not start without the clip in place. Be sure to remove the cord and store it in a safe place to prevent operation of the ATV when you are not around to supervise.

2-7

qWARNING

POTENTIAL HAZARD

Improper handling of gasoline.

WHAT CAN HAPPEN

Gasoline can catch fire and you could be burned.

HOW TO AVOID THE HAZARD

Always turn off the engine when refueling. Do not refuel right after the engine has been running and is still very hot.

Do not spill gasoline on the engine or exhaust pipe/muffler when refueling. Never refuel while smoking, or while in the vicinity of sparks, open flames, or other sources of ignition such as the pilot lights of water heaters and clothes dryers.

When transporting the ATV in another vehicle, be sure it is kept upright and that the fuel cock is in the “OFF” position. Otherwise, fuel may leak out of the carburetor or fuel tank.

WHAT CAN HAPPEN

Gasoline is poisonous and can cause injuries.

HOW TO AVOID THE HAZARD

If you should swallow some gasoline or inhale a lot of gasoline vapor, or get some gasoline in your eyes, see your doctor immediately.

If gasoline spills on your skin, wash with soap and water. If gasoline spills on your clothing, change your clothes.

2-8

qWARNING

POTENTIAL HAZARD

Starting or running the engine in a closed area.

WHAT CAN HAPPEN

Exhaust fumes are poisonous and may cause loss of consciousness and death within a short time.

HOW TO AVOID THE HAZARD

Always operate your ATV in an area with adequate ventilation.

EBU00062

Throttle lever

Once the engine is running, movement of the throttle lever will increase the engine speed. Regulate the speed of the machine by varying the throttle position. Because the throttle is spring-loaded, the machine will decelerate, and the engine will return to an idle any time the hand is removed from the throttle lever.

q

1. Throttle lever

Before starting the engine, check the throttle to be sure it is operating smoothly. Make sure it returns to the idle position as soon as the lever is released.

qWARNING

POTENTIAL HAZARD

Malfunction of throttle.

WHAT CAN HAPPEN

The throttle could be hard to operate, making it difficult to speed up or slow down when you need to. This could cause an accident.

HOW TO AVOID THE HAZARD

Check the operation of the throttle lever before you start the engine. If it does not work smoothly, check for the cause. Correct the problem before riding the ATV. Consult a Yamaha dealer if you can’t find or solve the problem yourself.

4-5

EBU10321

Speed limiter

The speed limiter keeps the throttle from fully opening, even when the throttle lever is pushed to the maximum. Screwing in the adjuster limits the maximum engine power available and decreases the maximum speed of the ATV.

Your ATV was delivered with an adjustable speed limiter. Yamaha recommends that all beginning riders start off with the speed limiter screw turned in to limit the amount of speed available while they learn. The limiter screw may be gradually turned out to increase maximum speed as the beginner becomes more familiar with operating the ATV.
