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 cleaned at the intervals speci-
fied in the periodic maintenance and lubrication
chart.
To check the engine oil level
1. Place the ATV on a level surface.
2. Warm up the engine for several minutes, and
then turn it off.
3. Wait at least ten minutes until the oil level set-
tles before checking.
4. Remove the engine oil filler cap, and then
wipe the dipstick off with a clean rag. Insert
the dipstick in the filler hole (without screwing
it in), and then remove it again to check the oil
level.NOTE:_

Be sure to wait at least ten minutes until the
oil level settles before checking.


The oil level should be between the minimum
and maximum level marks.
