removal and installation procedures.)
2. Place the ATV on a level surface and warm
up the engine for several minutes.
3. Stop the engine.
4. Remove the engine oil filler cap and wipe off
the dipstick with a clean rag.
5. Insert the dipstick in the filler hole without
screwing it in.NOTE:_ Wait a few minutes until the oil level settles before
checking. _6. The oil level should be between the maxi-
mum and minimum marks. If the level is low,
fill the engine with sufficient oil to reach the
specified level.

9. Fill the engine with sufficient oil to reach the
specified level. Install the engine oil filler cap
and tighten it.CAUTION:_

In 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.


Make sure that no foreign material enters
the crankcase.
