EBU20611To start out and accelerate
1. Release the throttle lever.NOTICEECB00200Always close the throttle before shifting gears,
otherwise damage to the engine and drive train
may result.2. Shift into first gear and release the shift pedal.3. Open the throttle gradually. WARNING! Al-
ways open the throttle gradually. Opening
the throttle abruptly would increase the
chance of an accident. It could make the
ATV wheelie or overturn.
[EWB00741]
4. Once the ATV has attained adequate speed,
release the throttle lever.
5. Shift into second gear and release the shift
pedal.
6. Open the throttle gradually.
7. Follow the same procedure when shifting to
the next higher gear.EBU20650To decelerate
When slowing down or stopping, release the throt-
tle and apply the brakes smoothly and evenly. As
you slow down, shift to a lower gear. Be sure that
the engine has sufficiently slowed before engaging
a lower gear. Improper use of the brakes or shifting
can cause the tires to lose traction, reducing con-
trol and increasing the possibility of an accident.
WARNING

6could make the wheels stop rotating and lose
traction. This could cause loss of control, an
accident and injury. It could also cause engine
or drive train damage.
NOTICEECB00190Even with the transmission in the neutral posi-
tion, do not coast for long periods of time with
the engine off, and do not tow the ATV for long
distances. The transmission is properly lubri-
cated only when the engine is running. Inade-
quate lubrication may damage the
transmission.EBU20672Engine break-in TIPFor ATVs equipped with an odometer or an hour
meter, follow the figures given in km (mi) or the
figures given in hours.For ATVs not equipped with an odometer or
hour meter, follow the figures given in hours.
There is never a more important period in the life of
your engine than the first 320 km (200 mi) or 20
hours of riding. For this reason, you should read
the following material carefully.
Since 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 through the gears 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.

chance of an accident. If you must park on an
incline, place the ATV transversely across the
incline, shift into first gear, stop the engine, ap-
ply the parking brake, and then block the front
and rear wheels with rocks or other objects.
Never park the ATV on hills that are too steep
to walk up easily.1. With the transmission in first gear, bring the
ATV to a stop by applying the brakes.
2. Stop the engine.
3. With the rear brake lever and brake pedal ap-
plied, apply the parking brake and slowly re-
lease the brake pedal.

Drive more slowly than you would without a load.
The more weight you carry, the slower you should
go. Although conditions vary, it is good practice to
drive slowly (shift into first gear or low drive if avail-
able on this model) whenever you are carrying
heavier loads or when towing a trailer.During operation
Always keep your feet on the footboards during op-
eration; otherwise, they may contact the rear
wheels. WARNING! Removing even one hand
or 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 contact with the rear wheels, which could
injure you or cause an accident.

Exhaust system
WARNING
EWB01501Dry grass or brush or other combustible ma-
terial accumulated around the engine area
could catch fire. Do not operate, idle, or park
the ATV in dry grass or other dry ground cov-
er. Keep the engine area free of dry grass,
brush, or other combustible material.Someone touching the exhaust system dur-
ing or after operation could be burned. Do
not touch the hot exhaust system. Do not
park the ATV in a place where others might
be likely to touch it.The muffler and other engine parts become ex-
tremely hot during operation and remain hot after
the engine has stopped. To reduce the risk of fire
during operation or after leaving the ATV, do not let
brush, grass and other materials collect under the
vehicle, near the muffler or exhaust pipe, or next to
other hot parts. Check under the vehicle after op-
erating in areas where combustible materials may
have collected. Do not idle or park the vehicle in
long dry grass or other dry ground cover.

7Select 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.
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. As you
get on the ATV, be sure not to accidentally move
the shift pedal. With the engine idling, lift the shift
pedal to the 1st gear position and then release the
parking brake. Apply the throttle slowly and
smoothly. The centrifugal clutch will engage and
you will start to accelerate. Once the ATV has at-
tained adequate speed, release the throttle and lift
the shift pedal to the 2nd gear position. Release
the shift pedal and apply the throttle smoothly.
WARNING! If the throttle is applied too abruptly
or if the throttle is not released during shifting,
or if the shift pedal is not released before ap-
plying the throttle, the front wheels may lift off
the ground, resulting in a loss of directional
control.
[EWB02631]
NOTICE: Do not shift gears
without releasing the throttle. Damage to the
engine or drive train may occur.
[ECB01071]
Use this same procedure as you move into the
higher gears. Be sure to coordinate the use of the
throttle and shift pedal properly.
Avoid higher speeds until you are thoroughly famil-
iar with the operation of your ATV.
When slowing down or stopping, release the throt-
tle and apply the brakes smoothly and evenly. As
you slow down, shift to a lower gear. Be sure that
the engine has sufficiently slowed before engaging
a lower gear. Improper use of the brakes or shifting
can cause the tires to lose traction, reducing con-
trol and increasing the possibility of an accident.
TURNING YOUR ATV
WARNING
EWB01771Always 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. ATV could go
out of control, causing a collision or overturn.To achieve maximum traction on unpaved surfac-
es, the two rear wheels turn together at the same
speed. Therefore, unless the wheel on the inside
of the turn is allowed to slip or lose some traction,
U1P065E0.book Page 12 Monday, August 31, 2009 1:10 PM

7 the ATV will resist turning. A special turning tech-
nique 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.
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.
