TIPPED SNOWMOBILE
(660 cc Models)
Tipping a snowmobile on its side is
sometimes desirable for maintenance
purposes; however, on a 660 cc model,
Arctic Cat recommends NOT TIP-
PING IT ON ITS SIDE IN EXCESS
OF A 70° ANGLE.
! CAUTION
The 660 cc models should not be
tipped on their sides in excess of
a 70° angle for any reason, as
engine oil may seep into the
upper engine through the air-
intake system. Severe engine
damage could result if the engine
is run with oil in the upper engine.
If a 660 cc model is tipped on its side
in excess of a 70° angle or if it has
been upside down at all, return the
snowmobile to the upright position
and use the following procedure:
1. With the ignition switch in the
OFF position, remove the engine
to air-intake silencer hose at the
engine. If oil is present, proceed
to step 2. If no oil is present,
install the hose and start the
engine.
! CAUTION
Care must be taken when install-
ing the hose that it does not sag
below the entrance/exit ends. If
there is a "valley" in the hose,
freezing may occur.
GENERAL INFORMATION
2. Remove the air-intake silencer
from the engine. If oil is present
in the air-intake silencer, proceed
to step 3. If no oil is present,
install the air-intake silencer and
the engine to air-intake silencer
hose; then start the engine.
NOTE: Prior to doing step 3,
clean the air silencer thoroughly.
3. Remove the spark plugs from the
engine and cover the spark plug
holes with a rag (see Spark Plugs
in this manual). With the emer-
gency stop button in the down
(OFF) position, turn the ignition
switch to the START position.
4. Allow the engine to turn over for
approximately 10 seconds. If oil
was noted coming from the spark
plug holes during this procedure,
repeat the process until all oil has
been discharged from the cylin-
ders.
5. Install the spark plugs, spark plug
wires, air-intake silencer, and the
engine to air-intake silencer hose.
NOTE: The engine should now
be safe to operate.
