SAFETY INFORMATION
EBU17534AN ATV IS NOT A TOY AND CAN BE HAZARD-OUS TO OPERATE.An ATV handles differently from other vehicles, in-
cluding motorcycles and cars. A collision or roll-
over can occur quickly, even during routine
maneuvers such as turning and riding on hills or
over obstacles, if you fail to take proper precau-
tions.
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 oper-
ate 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, park-
ing 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 regula-
tions 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.

ances. During this period, prolonged full-throttle
operation or any condition that might result in en-
gine overheating must be avoided.
0–160 km (0–100 mi) or 0–10 hours
Avoid prolonged operation above 1/2 throttle. Vary
the speed of the ATV regularly. Do not operate it at
one set throttle position.
160–320 km (100–200 mi) or 10–20 hours
Avoid prolonged operation above 3/4 throttle. Rev
the engine freely, but do not use full throttle at any
time.

The ATV can now be operated normally.
CAUTION:ECB00220If any engine trouble should occur during the
engine break-in period, immediately have aYamaha dealer check the ATV.
EBU20700Parking When parking the ATV, stop the engine, shift the
drive select lever into the forward position, apply
the parking brake, and then turn the fuel cock to
“OFF”.EBU20760Parking on a slope
WARNING
EWB00830Avoid parking on hills or other inclines. Park-
ing on a hill or other incline could cause the
ATV to roll out of control, increasing the
chance of an accident. If you must park on an
incline, place the ATV transversely across the
incline, shift the drive select lever to the for-
ward position, stop the engine, apply the park-
ing brake, and then block the front and rear
wheels with rocks or other objects.
Do not park the ATV at all on hills that are sosteep you could not walk up them easily.
1. Bring the ATV to a stop by applying the brakes
in the forward position.
2. Stop the engine.

7Loading and accessories
As originally equipped, this ATV is not designed to
carry cargo or tow a trailer. If you choose to add ac-
cessories so that you can carry cargo or tow a trail-
er, you must use common sense and good
judgment.
Use extra caution when riding the ATV with addi-
tional loads, such as accessories or cargo. The
ATV’s handling may be adversely affected. Re-
duce your speed when adding additional loads.
WARNING
EWB01460
Never exceed the stated load capacity for
this ATV.
Cargo should be properly distributed and se-
curely attached.
Reduce speed when carrying cargo or pull-
ing a trailer. Allow greater distance for brak-
ing.

Always follow the instructions in your Own-
er’s Manual for carrying cargo or pulling atrailer.
During operation
Always keep your feet on the footboards during op-
eration, otherwise they may contact the rear
wheels.
WARNING
EWB01470Always keep both hands on the handlebars
and both feet on the footboards of your ATV
during operation. Removing even one hand or MAXIMUM LOADING LIMIT

7 foot can reduce your ability to control the ATV
or could cause you to lose your balance and
fall off of the ATV. If you remove a foot from a
footboard, your foot or leg may come into con-
tact with the rear wheels, which could injure
you or cause an accident.
Avoid wheelies and jumping. You may lose control
of the ATV or overturn.
WARNING
EWB01480Never attempt stunts, such as wheelies orjumps. Don’t try to show off.Modifications
WARNING
EWB01490Never modify this ATV through improper in-
stallation or use of accessories. All parts and
accessories added to this ATV should be gen-
uine Yamaha or equivalent components de-
signed for use on this ATV and should be
installed and used according to instructions.
Improper installation of accessories or modifi-
cation of this ATV may cause changes in han-
dling which in some situations could lead to an
accident. If you have questions, consult an au-thorized ATV dealer.
Exhaust system
The exhaust system on the ATV is very hot during
and following operation. To prevent burns, avoid
touching the exhaust system. Park the ATV in a
place where pedestrians or children are not likely
to touch it. Also, avoid parking in or around dry
grass, brush or other combustible materials to pre-
vent causing a fire hazard.
WARNING
EWB01500
Do not touch the hot exhaust system.

7 Select a large, flat, unpaved area to become famil-
iar with your ATV. Make sure that this area is free
of obstacles and other riders. You should practice
control of the throttle, brakes, and turning tech-
niques in this area before trying more difficult ter-
rain. Always avoid riding on paved surfaces: the
ATV is designed for use on unpaved surfaces only,
and handling maneuvers are more difficult to per-
form on pavement.
Set the parking brake and follow the instruction on
page 6-1 to start the engine. Once it has warmed
up you are ready to begin riding your ATV. Re-
member that the engine and exhaust pipe will be
hot when riding and afterwards; do not allow skin
or clothing to come in contact with these compo-
nents.With the engine idling, return the starter (choke) to
the closed position and shift the drive select lever
into the forward position, then release the parking
brake. Apply the throttle slowly and smoothly. The
centrifugal clutch will engage and you will start to
accelerate. If the throttle is applied too abruptly, the
front wheels may lift off the ground, resulting in a
loss of directional control. Avoid higher speeds un-
til you are thoroughly familiar with the operation of
your ATV.
When slowing down or stopping, release the throt-
tle and apply the brakes smoothly and evenly. Im-
proper use of the brakes can cause the tires to lose
traction, reducing control and increasing the possi-
bility of an accident.
TURNING YOUR ATV
To achieve maximum traction on unpaved surfac-
es, the two rear wheels are mounted solidly on one
axle and turn together at the same speed. There-
fore, unless the wheel on the inside of the turn is al-
lowed to slip or lose some traction, the ATV will
resist turning. A special turning technique must be
used to allow the ATV to make turns quickly and
easily. It is essential that this skill be learned first at
low speed.

WARNING
EWB01570Always follow proper procedures for turning
as described in this Owner’s Manual. Practice
turning at low speeds before attempting to turn
at faster speeds. Do not turn at speeds too fastfor your skills or the conditions.
As you approach a curve, slow down and begin to
turn the handlebars in the desired direction. As you
do so, put your weight on the footboard to the out-
side of the turn (opposite your desired direction)
and lean your upper body into the turn. Use the
throttle to maintain an even speed through the turn.
This maneuver will let the wheel on the inside of
the turn slip slightly, allowing the ATV to make the
turn properly.This procedure should be practiced at slow speed
many times in a large unpaved area with no obsta-
cles. If an incorrect technique is used, your ATV
may continue to go straight. If the ATV doesn’t
turn, come to a stop and then practice the proce-
dure again. If the riding surface is slippery or loose,
it may help to position more of your weight over the
front wheels by moving forward on the seat.
Once you have learned this technique, you should
be able to perform it at higher speeds or in tighter
curves.
1. Lean towards inside of turn.
2. Support your weight on the outer footboard.
