SAFETY INFORMATION
EBU17631
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:
●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 1- 800-887-2887 to find out about the training courses nearest you.
●Always follow the age recommendation:
– A child under 6 years old should never operate
an ATV with engine size greater than 50 cc.
–A child under 12 years old should never operate an ATV with engine size greater than 70 cc.
–A child under 16 years old should never operate an ATV with engine size greater than 90 cc.
●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

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.
●Always 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.
●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 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 or pulling a trailer. Allow greater distance for braking.

TEACHING YOUR CHILD TO OPERATE THE ATV
EWB00040
WARNING
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 1 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. 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 tollfree 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 in-
1-4
struct your child. Go through this Owner’s Manual and the Parents, Youngsters and ATVs booklet
1page 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 7-11.) 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 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 4-5.)
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. Howev-
1-5
er, 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.
EWB00021
WARNING
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 1 running and is still very hot.
Do not spill gasoline on the engine or exhaust pipe/muffler when refueling.
Never refuel while smoking, or 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, seek medical help immediately. If gasoline spills on your skin, wash with soap and water. If gasoline spills on your clothing, change your clothes.
