SAFETY INFORMATION
EBU17481
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 fol-
low the operating procedures described.
● Never operate an ATV without proper training or
instruction. Take a Training Course.
should receive training from a certified instructor. Contact an authorized ATV dealer or call 1800-887-2887 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 90 cc.
Beginners
1
● 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, 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 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.
1-1
● Always inspect your ATV each time you use it to
make sure it is in safe operating condition. Al-
1
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 practiced 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 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. 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.
● Always use proper procedures if you stall or roll
backwards when climbing a hill. To avoid stalling, use the proper gear range and maintain a
1-2
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.
● 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 instructions in this manual for carrying cargo or
pulling a trailer. Allow greater distance for braking.

EWB00110
WARNING
POTENTIAL HAZARD
Riding too fast while the ATV is in fourwheel-drive differential gear lock.
4-7
WHAT CAN HAPPEN
All wheels turn at the same speed when the
differential is locked, so it takes more effort
to turn the ATV. The effort needed to turn increases with the riding speed. You may lose
control and have an accident if you cannot
make a sharp enough turn for the speed you
are traveling.
HOW TO AVOID THE HAZARD
Always ride at a slow speed when the ATV is
in four-wheel-drive differential gear lock, and
allow extra time and distance for maneuvers.
EBU26632

WARNING
POTENTIAL HAZARD
Changing from two-wheel drive to fourwheel drive or from four-wheel drive to twowheel drive while the ATV is moving.
WHAT CAN HAPPEN
The ATV handles differently in two-wheel
4
drive than in four-wheel drive in some circumstances. Changing from two-wheel drive
to four-wheel drive or from four-wheel drive
to two-wheel drive while moving may cause
the ATV to unexpectedly handle differently.
This could distract the operator and increase the risk of losing control and of causing an accident.
HOW TO AVOID THE HAZARD
Always stop the ATV before changing from
two-wheel drive to four-wheel drive or viceversa.
On-Command differential gear lock switch
“4WD”/“LOCK”
This ATV is equipped with a switch allowing you to

effort to turn the ATV. The effort needed to
turn increases with the riding speed. You
may lose control and have an accident if you
cannot make a sharp enough turn for the
speed you are traveling.
HOW TO AVOID THE HAZARD
Always ride at a slow speed when the ATV is
in differential gear lock, and allow extra time
and distance for maneuvers.
NOTE:
● When the switch is set to “LOCK”, the differential
gear lock indicator and indicator light will flash
until the differential gear is locked.
● When the indicator and indicator light are flash-
ing, turning the handlebar back and forth will
help the differential gear lock to engage.
● Riding before the differential gear lock is proper-
ly engaged (e.g., when the indicator and indicator light are flashing) will cause the engine speed
to be limited until engagement is complete.
