SAFETY INFORMATION
EBU00924
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 16 years old should never operate an ATV with engine size greater than 90cc.
●
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 passenger on an ATV.
U4KB1C.book Page 1 Wednesday, October 23, 2002 2:54 PM
●
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, long-sleeved shirt or
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 conditions. Always go at a speed that is
proper for the terrain, visibility and 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. Always 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 operating 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-
U4KB1C.book Page 2 Wednesday, October 23, 2002 2:54 PM
●
Always 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.
●
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 terrain 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.
●
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 vehicle 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 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
technique described in this manual on level ground. Avoid crossing the side of a steep hill if
possible.
U4KB1C.book Page 3 Wednesday, October 23, 2002 2:54 PM
●
Always 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.
●
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 be sure there are no obstacles or people behind you when you operate in reverse.
When it is safe to proceed in reverse, go slowly.
U4KB1C.book Page 4 Wednesday, October 23, 2002 2:54 PM
●
Always use the size and type 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.
●

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

Before starting the engine, check the throttle
to be sure it is operating smoothly. Make sure
it returns to the idle position as soon as the lever is released.
WARNING
POTENTIAL HAZARD
Malfunction of throttle.
WHAT CAN HAPPEN
The throttle could be hard to operate,
making it difficult to speed up or slow
down when you need to. This could
cause an accident.
HOW TO AVOID THE HAZARD
Check the operation of the throttle lever
before you start the engine. If it does not
work smoothly, check for the cause.
Correct the problem before riding the
