Engine oil
Make sure the engine oil is at the specified level.
Add oil as necessary. (See pages 8-15–8-25.)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.

Chain
Check the general condition of the chain and
check the chain slack before every ride. Lubricate
and adjust the chain as necessary. (See pages
8-67–8-71 for details.) Recommended engine oil type and quantity:

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 a few minutes until the oil level settles
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:_ The oil level should be between the minimum and
maximum level marks. _
