SAFETY INFORMATION
SAFETY INFORMATION
EBU17442
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.
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:
Take a Training Course.
Beginners
– 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.
●
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, 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.
1
●
Never attempt wheelies, jumps, or other stunts.
●
Always inspect your ATV each time you use it to
2
make sure it is in safe operating condition. Always follow the inspection and maintenance
3
procedures and schedules described in this
manual.
4
●
Always keep both hands on the handlebars and
both feet on the footboards of the ATV during
5
operation.
●
Always go slowly and be extra careful when op-
6
erating on unfamiliar terrain. Always be alert to
changing terrain conditions when operating the
7
ATV.
●
Never operate on excessively rough, slippery or
8
loose terrain until you have learned and prac-
9
ticed 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.
●
Always use proper procedures if you stall or roll
backwards when climbing a hill. To avoid stall-
1-2
ing, use the 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.
●
Always use the size and type of 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.
●
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.

CAUTION:
Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
4-8
rings, as well as to the exhaust system.
Your Yamaha engine has been designed to use
regular unleaded gasoline with a pump octane
number [(R+M)/2] of 86 or higher, or a research octane number of 91 or higher. If knocking or pinging
occurs, use a different brand of gasoline or premium unleaded fuel. Unleaded fuel will give you longer spark plug life and reduced maintenance cost.
Gasohol
There are two types of gasohol: gasohol containing ethanol and that containing methanol. Gasohol
containing ethanol can be used if the ethanol content does not exceed 10%. Gasohol containing
methanol is not recommended by Yamaha because it can cause damage to the fuel system or
ATV performance problems.

WARNING
POTENTIAL HAZARD
Improper care when refueling.
WHAT CAN HAPPEN
Fuel can spill, which can cause a fire and severe injury.
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.
HOW TO AVOID THE HAZARD
Do not overfill the fuel tank. Be careful not to
spill fuel, especially on the engine or exhaust
pipe. Wipe up any spilled fuel immediately.
Be sure the fuel tank cap is closed securely.
Do not refuel right after the engine has been
running and is still very hot.
