SAFETY INFORMATION

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. Beginners
should receive training from a certified instructor. Contact an authorized ATV dealer 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.
● 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.
● This vehicle is intended for off-road use only. Do
not operate on any paved surfaces such as:
sidewalks, driveways, parking lots, paved roads,
public streets or other motorway.
● Watch carefully for other vehicles when operat-
ing on unpaved public streets or roads. Make
sure you know your country’s laws and regulations before you ride on unpaved public streets
or roads.
● 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.
2-1
● 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. 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 footrests 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 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.
2
2-2
● Always use proper procedures if you stall or roll
backwards when climbing a hill. To avoid stalling, use the proper gear and maintain a steady
speed when climbing a hill. If you stall or roll
2
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 use the size and type of tires specified in
this manual.
● Always maintain proper tire pressure as de-
scribed in this manual.
● 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.
● Do not operate your ATV during darkness un-
less it is equipped with a properly functioning
headlight. Off-road riding is inherently dangerous and additionally, off-road trails do not have
streetlights to guide you.
● Never maintain an ATV without proper knowl-
edge. Contact an authorized ATV dealer to inform you on basic ATV maintenance. Certain
maintenance can only be carried out by certified
staff.
2-3
In the event of an accident
1. If serious injuries are incurred, you may be
safer staying next to your vehicle; it may
shield you from oncoming riders. Depending
on your injuries and position in the trail; you
must make a judgment call as to whether you
should move to a position off the trail. If you
have sustained head, neck, or back injuries,
or cannot feel your limbs, you should not
move. Keep your helmet on and remain motionless. Lie down next to your vehicle and
wait for help.
2. If less serious injuries are incurred and you
can walk, then move to a position off the trail.
Check yourself for injuries and apply first aid
as needed.
3. If your injuries are light, when safe to do so,
move your vehicle off the trail to avoid collisions with oncoming riders. Check for injuries
and apply first aid as necessary. If you can
physically operate your vehicle, inspect your
vehicle. If the vehicle is in safe operating condition and you can safely operate it, restart it
and ride gently back to camp or other known
location where you can receive medical atten-
tion. If necessary, contact your riding party or
local authorities to let them know where you
are and what has happened.
In the event of a breakdown
1. If your vehicle will not restart or is not in safe
operating condition, turn off the main switch
and engine stop switch. If the breakdown occurs at twilight or night, leave the main switch
on so that your lights may warn other riders of
your stopped vehicle.
2. Get out of danger. Check for oncoming vehicles and when safe, push your vehicle to the
side of the trail or even off the main trail to
avoid any possible collisions with oncoming
riders. If you cannot move your vehicle by
yourself, when safe, walk to the nearest vantage point and signal an oncoming rider to
help you push your vehicle to a safe place off
the trail.
3. Inspect your vehicle for any immediate hazardous conditions. The most obvious hazardous conditions are leaking fuel and
ungrounded or broken wiring. Visually check
for broken wiring and leaking fuel. Leaking
fuel can be confirmed by the odor of gasoline.
2
2-4
4. Once immediate safety hazards are confirmed not to exist, you may remove your helmet to more closely inspect your vehicle.
Check for external signs of wear, broken
2
parts, fluid leaks, cracks in the frame, suspension damage, wheel damage, and so on. Fuel,
oil, and coolant usually give off a noticeable
odor.
5. If your vehicle will not restart or if it is unsafe
to ride, then turn off all vehicle systems (engine stop switch, main switch, and fuel cock),
and then signal or go for help.
Aftermarket Parts, Accessories, and Modifications
While you may find aftermarket products similar in
design and quality to genuine Yamaha accessories, recognize that some aftermarket accessories
or modifications are not suitable because of potential safety hazards to you or others. Installing aftermarket products or having other modifications
performed to your vehicle that change any of the
vehicle’s design or operation characteristics can
put you and others at greater risk of serious injury
or death. You are responsible for injuries related to
changes in the vehicle. Keep the following guidelines in mind, as well as those provided under
“Loading” when mounting accessories.
● Never install accessories that would impair the
performance of your ATV. Carefully inspect the
accessory before using it to make sure that it
does not in any way reduce ground clearance,
limit suspension travel, steering travel or control
operation.
● Accessories fitted to the ATV can create instabil-
ity due to improper weight distribution.
● Bulky or large accessories may seriously affect
the stability of the ATV.
● Certain accessories can displace the operator
from his or her normal riding position. This improper position limits the freedom of movement
of the operator and may limit control ability,
therefore, such accessories are not recommended.
● Use caution when adding electrical accessories.
If electrical accessories exceed the capacity of
the ATV’s electrical system, an electric failure
could result, which could cause a dangerous
loss of lights or engine power.

WARNING
EWB00072
WARNING
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon monoxide,
a deadly gas. Breathing carbon monoxide can
cause headaches, dizziness, drowsiness, nausea, confusion, 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 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
windows and doors, carbon monoxide can
rapidly reach dangerous levels.
● Do not run engine in poorly ventilated or par-
tially enclosed areas such as barns, garages,
or carports.
● Do not run engine outdoors where engine
exhaust can be drawn into a building
through openings such as windows and
doors.

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.
