8In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives. Do not
use oils with a diesel specification of “CD”
or oils of a higher quality than specified. In
addition, do not use oils labeled “ENERGY
CONSERVING
II” or higher.
8Make sure that no foreign material enters
the crankcase.

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”.

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)

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.
