Starting a warm engine
To start a warm engine, refer to the “Starting a
cold engine” section. The starter (choke)
should not be used. The throttle should be
opened slightly.
EBU00538
Warming up
To get maximum engine life, always warm up
the engine before starting off. Never accelerate
hard with a cold engine! To see whether or not
the engine is warm, check if it responds to the
throttle normally with the starter (choke)
turned off.NOTE:

When the parking brake is used, engine speed
is limited to 2,300 r/min. Be sure the parking
brake is released before moving the throttle le-
ver. Otherwise, the engine will misfire, pre-
venting normal operation.

When shifting into reverse, the clutch must be
disengaged.
1. Bring the machine to a complete stop and
return the throttle lever to the closed posi-
tion.
2. Pull in the clutch lever to disengage the
clutch.
3. Apply the rear brake pedal.
4. While pulling the knob, move the drive se-
lect lever toward the rear until it complete-
ly stops.

Shifting
This model has a 6-speed forward and 1-speed
reverse transmission. The transmission allows
you to control the amount of power you have
available at a given speed or for starting, accel-
erating, climbing hills, etc. To shift into neutral,
return the throttle lever to its original position,
apply the clutch and repeatedly depress the
shift pedal until it stops. When it stops, it will
be in first gear. Raise the pedal slightly to neu-
tral.
CAUTION:

1. Do not coast for long periods with the en-
gine off, and do not tow the machine a
long distance. Even in neutral position,
the transmission is only properly lubricat-
ed when the engine is running. Inade-
quate lubrication may cause damage.
2. Always use the clutch when changing
gears. The engine, transmission and driv-
etrain are not designed to withstand the
shock of forced shifting and can be dam-
aged by shifting without the clutch.

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 outside 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, al-
lowing the ATV to make the turn properly.
This procedure should be practiced at slow
speed many times in a large off-road area with
no obstacles. 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 procedure again. If the riding sur-
face 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 footrest.
1. Se pencher vers l’intérieur du virage.
2. S’appuyer sur le repose-pied externe.
1. Inclínese hacia el interior del giro.
2. Descanse su peso en el descansapie externo.

CROSSING A SLOPE
Traversing a sloping surface on your ATV re-
quires you to properly position your weight to
maintain proper balance. Be sure that you
have learned the basic riding skills on flat
ground before attempting to cross a sloping
surface. Avoid slopes with slippery surfaces or
rough terrain that may upset your balance.
As you travel across a slope, lean your body in
the uphill direction. It may be necessary to cor-
rect the steering when riding on loose surfaces
by pointing the front wheels slightly uphill.
When riding on slopes be sure not to make
sharp turns either up or down hill.

Oil pressure check
1. Put a cloth around the cylinder.
2. Slightly loosen the oil gallery bolt in the
cylinder head.
3. Start the engine and keep it idling until oil
begins to seep from the oil gallery. If no oil
comes out after one minute, turn the en-
gine off so it will not seize and find the
cause.
4. Start the engine, and then check the oil
pressure.
5. After checking, tighten the oil gallery bolt
to the specified torque.CAUTION:Be sure to check the oil pressure after replac-ing the engine oil. Tightening torque:
