Engine oil and oil filter cartridge
The engine oil level should be checked before
each ride. In addition, the oil must be changed and
the oil filter cartridge replaced at the intervals
specified in the periodic maintenance and lubrica-
tion 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 temperature of
60°C, let it continue to idle for twenty to thirty
seconds. During this period, rev the engine
two or three times to approximately
3,000 r/min, 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. Wait a few minutes until the oil settles, re-
move 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 recommended
type to raise it to the correct level.NOTE:_ When adding oil, be careful not to overfill the en-
gine oil tank; the oil level rises faster starting from
the half-level-portion on the dipstick. _5. Insert the dipstick into the oil filler hole, and
then tighten the oil filler cap.

4. Remove the crankcase engine oil drain bolt.
5. Remove the engine oil tank filler cap and the
oil tank drain bolt.
6. Check the washers for damage, and replace
if necessary.NOTE:_ Skip steps 7–9 if the oil filter cartridge is not being
replaced. _

11. Pour only 1.75 L of the specified amount of
recommended engine oil through the engine
oil tank filler hole, insert the dipstick, and then
tighten the oil tank filler cap.
12. Start the engine, rev it several times, and
then turn it off.
13. Remove the engine oil tank filler cap, and
then gradually fill the oil tank with the remain-
ing oil quantity while regularly checking the oil
level on the dipstick.
14. Install the engine oil tank filler cap.Tightening torques:

15. Start the engine, and then let it idle for seve-
ral minutes while checking it for oil leakage. If
oil is leaking, immediately turn the engine off
and check for the cause.
16. Turn the engine off, and then check the oil
level and correct it if necessary.
17. Install the engine guard by installing the bolts.
