Transmission oil
Make sure the transmission oil is at the specified
level. Add oil as necessary. (See pages 8-17 ~
8-23.)
cC
Be sure to use motor oils that do not contain
anti-friction modifiers. Passenger car motor
oils (often labeled “Energy Conserving”) con-
tain anti-friction additives which will cause
clutch and/or starter clutch slippage, result-
ing in reduced component life and poor
engine performance.
Recommended oil:
SAE 10W30
Recommended oil classification:
API Service SE, SF, SG type or higher
Oil quantity:
Total amount:
1.7 L
Periodic oil change:

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:

6-5
Position1: Cold engine start-
ambient temperature below 5°C.
Position2: Cold engine start-
ambient temperature at 0°C ~ 30°C
and warming up position.
Position3: 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.

cC
1. Do 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 lubri-
cated when the engine is running. Inade-
quate lubrication may cause damage.
2. Always 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
damaged by shifting without the clutch.
