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 inter-
vals specified 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 a few 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. In-
sert the dipstick in the filler hole (without
screwing it in), and then remove it again
to check the oil level.
1. Engine oil filler cap
NOTE:
_
The oil level should be between the minimum
and maximum level marks.

5. If the engine oil is at or below the mini-
mum level mark, add sufficient oil of the
recommended type to raise it to the cor-
rect level.
CAUTION:
_
Be sure no foreign material enters the
crankcase.
