MAINTENANCE

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. Also, assure
the engine is "cooled down" to
room temperature to allow the oil
to drain into the sump.
1. Using a flat-blade screwdriver,
release the hood latch; then release
the two hold-down straps and open
the hood.
2. Rotate the oil level stick counter-
clockwise; then remove the stick
from the crankcase and wipe it
clean.
CAUTION
Clean the area around the fill hole
to keep dirt, debris, etc., out of the
engine.
3. Insert the stick into the crankcase;
then remove and check oil level on
the stick.

CAUTION
Seeing oil in the crankcase does
not mean the level is in the safe

oil level below the point of overflow-
ing the fill hole.
 NOTE: If the oil level is below the
oil level mark, add recommended
oil until it reaches the oil level
mark.
4. Insert the oil level stick into the
crankcase; then rotate the stick
clockwise until snug.
5. Close the hood and secure with the
straps and latch.
Changing
To change the engine oil, use the fol-
lowing procedure:

bile must be elevated until the
