Engine oil
Make sure the engine oil is at the specified level.
Add oil as necessary. (See page 8-25.)
cC
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.
Recommended engine oil type and quantity:
See page 10-2.

Engine oil and oil filter element
The engine oil level should be checked before
each ride. In addition, the oil must be changed
and the oil filter element replaced at the intervals
specified in the periodic maintenance and lubri-
cation chart.
To check the engine oil level
1. Place the ATV on a level surface.
2. Start the engine, warm it up until the
engine oil has reached a normal tempera-
ture of 40 ° C, let it continue to idle for ten
seconds or more, and then turn the engine
off.
NOTE:
To achieve the proper engine oil temperature for
an accurate oil level reading, the engine must
have first completely cooled down, and then
warmed up again for several minutes to normal
operating temperature.

3. Remove the engine oil tank filler cap, wipe
the dipstick clean with a clean rag, insert it
back into the filler hole (without screwing it
in), and then remove it again to check the
oil level.
NOTE:
The engine oil should be between the minimum
and maximum level marks.
4. If the engine oil is below the minimum level
mark, add sufficient oil of the recommend-
ed type through the engine oil tank filler
hole to raise it to the correct level.
NOTE:
When adding oil, be careful not to overfill the
engine oil tank; the oil level rises faster starting
from the half-level-portion on the dipstick.
5. Insert the dipstick into the engine oil tank
filler hole, and then tighten the engine oil
tank filler cap.

Make sure that the engine oil tank filler cap
is securely tightened, otherwise oil may seep
out when the engine is running.
To change the engine oil (with or without oil
filter element replacement)
1. Remove the engine guard by removing the
bolts.
2. Start the engine, warm it up for several
minutes, and then turn it off.
3. Place an oil pan under the engine to collect
the used oil.
