SAFETY INFORMATION
EBU17562
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.
● 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.
1
● Never carry a passenger on an ATV.
● Always avoid operating an ATV on any paved
surfaces, including sidewalks, driveways, parking lots and paved streets.
● Never operate an ATV on any paved street,
paved road or 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.
● 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. Maintain a
steady speed when climbing a hill. If you stall or
1-2
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.
EWB00061
WARNING
● Always turn off the engine when refueling.
● Do not refuel right after the engine has been
running and is still very hot.
● Do not spill gasoline on the engine or ex-
haust pipe/muffler when refueling. Never refuel while smoking, or in the vicinity of
sparks, open flames, or other sources of ig-
1
1-3
nition such as the pilot lights of water heaters and clothes dryers. Gasoline can catch
1
fire and you could be burned.
● When transporting the ATV in another vehi-
cle, 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.
● Gasoline is poisonous. If you should swal-
low some gasoline or inhale a lot of gasoline
vapor, or get some gasoline in your eyes,
seek medical help immediately. If gasoline
spills on your skin, wash with soap and water. If gasoline spills on your clothing,
change your clothes.
EWB00070
WARNING
Always operate your ATV in an area with adequate ventilation. Never start or run the engine
in a closed area. Exhaust fumes are poisonous
and may cause loss of consciousness and
death within a short time.

WARNING
● Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is overfilled,
fuel could spill out due to heat from the engine or the sun.
● Be careful not to spill fuel, especially on the
engine or exhaust pipe which can cause a
fire and severe injury. Wipe up any spilled
fuel immediately.
● Do not refuel right after the engine has been
running and is still very hot.
● Be sure the fuel tank cap is closed securely.
