AN IMPORTANT NOTE TO PARENTS:
This ATV is not a toy. Before you let your child ride this ATV, you should understand the instructions and
warnings in this Owner’s Manual. Then be sure your child understands and will follow them. Children differ
in skills, physical abilities and judgment. Some children may not be able to operate an ATV safely. Parents
should supervise their child’s use of the ATV at all times. Parents should permit continued use only if they
determine that the child has the ability to operate the ATV safely.
Your ATV was delivered with an adjustable speed limiter. Yamaha recommends that all beginners start off
with the speed limiter screw turned in to limit the amount of speed available while they learn. The speed
limiter screw may be gradually turned out to increase maximum speed as the beginner becomes more familiar with operating the ATV.
If your child is a beginner or is inexperienced, he or she should take a training course. See the previous
page for information about the free training available to purchasers of new ATVs.

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
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-

struct 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
3
safety equipment
Your child must always wear an approved motor-

cycle helmet that fits properly. Your child should
also wear the safety equipment described in the

Riding Your ATV section of this manual.
6
Choose an appropriate riding area
Select an area appropriate for your child to learn to
7
ride. (See page 7-11.) Follow the instructions in
the Riding Your ATV section of this manual.
8
Choose a large, flat off-road area that is free of obstacles and away from other vehicles.
9
Supervise every use of the ATV
10
Because an adult must supervise every ATV operator under age 16, you should closely watch your
11
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
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.

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

WARNING
POTENTIAL HAZARD
Malfunction of throttle.
WHAT CAN HAPPEN
The throttle could be hard to operate, making
