Starting a cold engine
w
Always make sure all control cables work
smoothly before you begin riding in cold
weather. If the control cables are frozen or
do not work smoothly, you could be unable
to control the ATV, which could lead to an
accident or collision.
1. Set the parking brake.
2. Turn the fuel cock to “ON”.
3. Turn the main switch to “ON” and the engine
stop switch to “RUN”.
4. Shift the transmission into neutral.
5. Use the starter (choke) in reference to the
figure:

Position 1: Cold engine start-
ambient temperature below 5°C.
Position 2: Cold engine start-
ambient temperature at 0°C–30°C
and warming up position.
Position 3: Cold engine start-
ambient temperature above 25°C
and warm engine start position.
6. Completely close the throttle lever and start
the engine by kicking the kick starter.
7. If the engine is started with the starter
(choke) in position 1, the starter (choke)
should be returned to position 2to warm up
the engine. If the engine is started with the
starter (choke) in position 2, keep the
starter (choke) in this position to warm up
the engine.

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
lever. Otherwise, the engine will misfire, pre-
venting normal operation.

8Do not coast for long periods with the
engine off, and do not tow the machine a
long distance. Even in neutral position, the
transmission is only properly lubricated
when the engine is running. Inadequate
lubrication may cause damage.
8Always use the clutch when changing
gears. The engine, transmission and drive
train are not designed to withstand the
shock of forced shifting and can be dam-
aged by shifting without the clutch.

To start out and accelerate
1. Release the throttle lever.
cC
Always close the throttle while shifting
gears. Otherwise, damage to the engine and
drive train may result.
2. Pull the clutch lever to disengage the clutch.
3. Shift into first gear.
4. Open the throttle gradually and at the same
time, release the clutch lever slowly.
5. Once the machine has attained adequate
speed, release the throttle, and at the same
time, quickly pull in the clutch lever.
6. Shift into second gear. (be careful not to
shift into neutral)

To decelerate
When slowing down or stopping, release the
throttle 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 control and increasing the
possibility of an accident.
w
Make sure the engine has sufficiently slowed
before shifting to a lower gear. Engaging a
lower gear when the engine speed is too
high could make the wheels stop rotating.
This could cause loss of control, an accident
and injury. It could also cause engine or
drive train damage.
