SAFETY INFORMATION

EBU17542

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. Take a Training Course. Beginners

should receive training from a certified instruc-

tor. 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 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 a 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

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 footboards of the ATV during

operation.

●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. 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.

Avoid crossing the side of a steep hill if possible.

●Always use proper procedures if you stall or roll

backwards when climbing a hill. Maintain a

steady speed when climbing a hill. If you stall or
