ENGINE OIL

NOTE: After the engine break-in
period, the engine oil should be
changed every 100
hours (6 months) and before pro-
longed storage.
Checking
The engine oil level should be checked
each day before operating the snowmo-
bile. To check the engine oil level, use
the following procedure:
NOTE: The front of the snowmo-
bile must be elevated until the
engine is in a level position when
checking the oil level.
1. Release the two hold-down straps
and open the hood.
2. Rotate the oil filler plug/level stick
3-4 rotations counterclockwise;
then remove the stick from the
crankcase and wipe it clean. Insert
the stick into the crankcase.
3. Remove the stick and make sure
the oil is visible on the stick
(above the lower oil level mark).
NOTE: If the oil level is at or
below the lower oil level mark, add
recommended oil until it reaches
the upper oil level mark.
4. Insert the oil level stick into the
crankcase; then rotate the stick
clockwise until snug.
