This manual will provide you with a good basic understanding of the features and operation of this ATV.

This manual includes important safety information. It provides information about special tech-

niques and skills necessary to ride the ATV. It also includes basic maintenance and inspection proce-

dures. If you have any questions regarding the operation or maintenance of your ATV, please consult an

E-TON dealer.

AN IMPORTANT SAFETY MESSAGE:

READ THIS MANUAL TOGETHER WITH TIPS FOR THE ATV RIDER CAREFULLY AND COMPLETE-

LY BEFORE OPERATING YOUR ATV. MAKE SURE YOU UNDERSTAND ALL INSTRUCTIONS.

PAY CLOSE ATTENTION TO THE WARNING AND NOTICE LABELS ON THE ATV.

THE VIPER 90 & VIPER 90R, AND ANY OTHER ATV OVER 70 cc, SHOULD NOT BE OPERATED

BY A CHILD UNDER 12 YEARS OF AGE.

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. E-TON recommends that all beginners start off

to limit the amount of speed available while they learn. As the beginner becomes more familiar with operating

the ATV. Parents should decide when to adjust the ATV for more power as their youngster's riding skills

improve. Once the ATV rider can operate with skill at the top speed permitted by adjusting the speed limiter

alone, turn the speed limiter completely back in again; adjust it out in stages as you did before.

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.

SAFETY INFORMATION

AN ATV IS NOT A TOY AND CAN BE HAZARD-

OUS TO OPERATE.

An ATV handles differently from other vehicles, in-

cluding motorcycles and cars. A collision or roll-

over can occur quickly, even during routine

maneuvers such as turning and riding on hills or

over obstacles, if you fail to take proper precau-

tions.

SEVERE INJURY OR DEATH can result if you do

not follow these instructions:

Read this manual and all labels carefully and fol-

low the operating procedures described.

Never operate an ATV without proper training or

instruction.

Always follow the age recommendation:

– A child under 12 years old should never oper-

ate an ATV with engine size greater than 70 cc.

– A child under 16 years old should never oper-

ate 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, park-

ing lots and streets.

Never operate an ATV on any public street, road

or highway, even dirt or gravel one.

Never operate an ATV without wearing an ap-

proved 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

– A child under 6 years old should never operate

an ATV with engine size greater than 50 cc.

operating this ATV.

Never operate at speeds too fast for your skills

or the riding conditions. Always go at a speed

that is proper for the terrain, visibility, operating

conditions, and your experience.

Never attempt wheelies, jumps, or other stunts.

Always inspect your ATV each time you use it to

make sure it is in safe operating condition. Al-

ways follow the inspection and maintenance

procedures and schedules described in this

manual.

Always keep both hands on the handlebars and

both feet on the footrests of the ATV during op-

eration.

Always go slowly and be extra careful when op-

erating on unfamiliar terrain. Always be alert to

changing terrain conditions when operating the

ATV.

Never operate on excessively rough, slippery or

loose terrain until you have learned and prac-

ticed the skills necessary to control the ATV on

such terrain. Always be especially cautious on

these kinds of terrain.

Always follow proper procedures for turning as

described in this manual. Practice turning at low

speeds before attempting to turn at faster

speeds and never turn at excessive speeds.

Never operate the ATV on hills too steep for the

ATV or for your abilities. Practice on smaller hills

before attempting larger hills.

Always follow proper procedures for climbing

hills as described in this manual. Check the ter-

rain carefully before you start up any hill. Never

climb hills with excessively slippery or loose sur-

faces. 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.

Always 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 ve-

hicle to lean sharply to one side. Go straight

down the hill where possible.

Always follow proper procedures for crossing

the side of a hill as described in this manual.

Avoid hills with excessively slippery or loose sur-

faces. 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 tech-

nique described in this manual on level ground.

www.Get2itParts.com

1-3

Avoid crossing the side of a steep hill if possible.

Always use proper procedures if you stall or roll

backwards when climbing a hill. To avoid stall-

ing, use the proper gear and maintain a steady

speed when climbing a hill. If you stall or roll

backwards, follow the special procedure for

braking described in this manual. Dismount on

the uphill side or to a side if pointed straight up-

hill. 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 obsta-

cles 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 re-

duce the chance of skidding or sliding out of con-

trol.

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 de-

scribed in this manual.

Never modify an ATV through improper installa-

tion 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 in-

structions in this manual for carrying cargo or

pulling a trailer. Allow greater distance for brak-

ing.

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.

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 properly trained

Your child should take a certified training course.

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, 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 motor-

cycle 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 ob-

stacles and away from other vehicles.

how to operate an ATV safely. A child who is too

tired or distracted should not be allowed to operate

the ATV.

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

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.

Introduce new riding areas slowly and make

sure the riding area matches your child’s

skill level.

TEACHING YOUR CHILD TO OPERATE THE

ATV (FOR VIPER 70)

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.

WARNING

www.Get2itParts.com

1-5

Supervise every use of the ATV

Because an adult must supervise every ATV oper-

ator 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 operat-

ing 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 left side the vehicle.

ENGINE STOP SWITCH CORD

This model has an engine stop switch cord (lan-

yard) 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 4-7.)

1. Push the rubber cap on the end of the engine

stops witch 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 left side 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 po-

tentially hazardous situation might be encoun-

tered.

When your child has developed sufficient skill to no

longer need you to follow with the cord, the cord

can be stowed on the handlebars of the ATV.Howev-

er, you must still closely supervise your child at all

times during ATV operation.

TIP

The ATV will not start without the rubber cap 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.

Avoid Carbon Monoxide Poisoning

carbon monoxide can collect rapidly and you can

quickly be overcome and unable to save yourself.

Also, deadly levels of carbon monoxide can linger

for hours or days in enclosed or poorly ventilated

areas. If you experience any symptoms of carbon

monoxide poisoning, leave the area immediately,

get fresh air, and SEEK MEDICAL TREATMENT.

Do not run engine indoors. Even if you try to

ventilate engine exhaust with fans or open win-

dows and doors, carbon monoxide can rapidly

reach dangerous levels.

Do not run engine in poorly ventilated or partially

enclosed areas such as barns, garages, or car-

ports.

Do not run engine outdoors where engine exh-

aust can be drawn into a building through open-

ings such as windows and doors.

All engine exhaust contains carbon monoxide, a

deadly gas. Breathing carbon monoxide can cause

headaches, dizziness, drowsiness, nausea, con-

fusion, and eventually death.

Carbon Monoxide is a colorless, odorless, tasteless

gas which may be present even if you do not see

or smell any engine exhaust. Deadly levels of
