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 these age recommendation:
– 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.

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 footpegs 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.

2-3
8Never 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.
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 ter-
rain 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 back-
ward. 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 tech-
nique described in this manual on level ground. Avoid crossing the side of a steep hill if possi-
ble.
5FK-9-16-01 3/13/03 11:13 AM Page 13

2-4
8Always use proper procedures if you stall or roll backwards when climbing a hill. To avoid
stalling, use 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 uphill. Turn the ATV around and remount, following the
procedure described in this manual.
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 fol-
low 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 prac-
ticing 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 con-
trol.
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.
5FK-9-16-01 3/13/03 11:13 AM Page 14

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.
