6Since the engine is brand new, do not put an ex-
cessive load on it for the first 320 km (200 mi) or 20
hours. The various parts in the engine wear and
polish themselves to the correct operating clear-
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.
320 km (200 mi) or 20 hours and beyond
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.
EBU27321Parking When parking the ATV, stop the engine, and shift
the drive select lever into the park position.EBU20820Parking on a slope
WARNING
EWB00860Avoid 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, stop the engine, shift the drive select
lever to the park position, and then block the
front and rear wheels with rocks or other ob-
jects.
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.
2. Stop the engine.
3. With the brake pedal applied, shift the drive
select lever to the park position.

7Not recommended for children under 16 years
of age.
WARNING
EWB01390A child under 16 should never operate an ATV
with engine size greater than 90 cc. Use by chil-
dren of ATVs that are not recommended for
their age can lead to severe injury or death ofthe child.This ATV is designed to carry operator and car-
go only – passengers prohibited.
WARNING
EWB01400Never carry a passenger. The long seat is to al-
low the operator to shift position as needed
during operation. It is not for carrying passen-
gers. Carrying a passenger on this ATV greatly
reduces your ability to balance and control this
ATV. It could cause an accident, resulting inharm to you and/or your passenger.

7 in the Owner’s Manual. Failure to inspect the
ATV before operating or failure to properly
maintain the ATV increases the possibility of
an accident or equipment damage.
WARNING
EWB01440Always use the size and type tires specified in
the Owner’s Manual for this ATV on page 5-5.
Always maintain proper tire pressure as de-
scribed in the Owner’s Manual on page 5-6.
Use of improper tires on this ATV, or operation
of this ATV with improper or uneven tire pres-
sure, may cause loss of control, increasingyour risk of an accident.
Do not operate at speeds too fast for your skills
or the conditions.
WARNING
EWB01450Always go at a speed that is proper for the ter-
rain, visibility and operating conditions, and
your experience. Operating this ATV at speeds
too fast for your skills or the conditions in-
creases your chances of losing control of theATV, which can result in an accident.Speed limiter
For riders less experienced with this model, the
throttle lever housing is equipped with a speed lim-
iter. The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed to
the maximum. Turning in the adjusting screw limits
the maximum engine power available and de-
creases the maximum speed of the ATV. Turning
in the adjusting screw decreases top speed, and
turning it out increases top speed. (See page
4-13.)

WARNING
EWB01550Always mount a caution flag on the ATV to
make you more visible when operating in areas
where you might not be seen by other vehicles.Watch carefully for other vehicles.
Do not ride in areas posted “no trespassing”.
Do not ride on private property without getting per-
mission.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, shifting procedures,
and turning techniques in this area before trying
more difficult terrain. Always avoid riding on paved
surfaces: the ATV is designed for use on unpaved
surfaces only, and handling maneuvers are more
difficult to perform on pavement.
Shift to the park position 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.
Remember 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 com-
ponents.U3B462E0.book Page 12 Tuesday, March 20, 2007 11:46 AM

7With the engine idling, shift the drive select lever
into the low-range position or the high-range posi-
tion. 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.
CAUTION:ECB00250Do not shift from drive position low-range to
high-range or vice versa without coming to a
complete stop. Damage to the engine or drivetrain may occur.
TURNING YOUR ATV
To achieve maximum traction on unpaved surfac-
es in 2WD or 4WD, the two rear wheels turn to-
gether at the same speed. Furthermore, when
riding in 4WD-LOCK (“DIFF. LOCK”), the frontwheels also turn together at the same speed.
Therefore, unless the wheel on the inside of the
turn is allowed 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
EWB01770Always 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 fast
for your skills or the conditions. Operate at a
slow speed and allow extra time and distance
for maneuvers when in 4WD-LOCK (“DIFF.LOCK”).
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.

7could come off the ground. The ATV could easily
tip over backwards. Apply both the front and rear
brakes gradually, or dismount the ATV immediate-
ly on the uphill side.
WARNING
EWB01801Use the proper gear and maintain a steady
speed when climbing a hill.
If you lose all forward speed:
Keep weight uphill.
Apply the brakes.
Shift into the park position after you are
stopped.
If you begin rolling backwards:
Keep weight uphill.
2WD: Never apply the rear brake while rolling
backwards. Apply the front brake.
4WD or 4WD-LOCK: Apply both front and
rear brakes gradually.
When fully stopped, shift into the park posi-
tion.
Dismount on uphill side or to a side if pointed
straight uphill. Turn the ATV around and re-
mount, following the procedure described inthe Owner’s Manual.RIDING DOWNHILL
When riding your ATV downhill, shift your weight
as far to the rear and uphill side of the ATV as pos-
sible. Move back on the seat and sit with your arms
straight. Engine compression will do most of the
braking for you. For maximum engine compres-
sion braking effect, select the low-range position
and change to 4WD or 4WD-LOCK before begin-
ning to descend the hill. Improper braking may
cause a loss of traction.
Use caution while descending a hill with loose or
slippery surfaces. Braking ability and traction may
be adversely affected by these surfaces. Improper
braking may also cause a loss of traction.U3B462E0.book Page 17 Tuesday, March 20, 2007 11:46 AM
