Tipped Snowmobile
(660 cc Models)
Tipping the snowmobile on its side is sometimes desir-
able for maintenance purposes; however, on a 660 cc
model, Arctic Cat recommends NOT TIPPING 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 snow-
mobile to the upright position and use the following pro-
cedure:
1. With the ignition switch in the OFF position,
remove the engine to air 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.
2. Remove the air silencer from the engine. If oil is
present in the air silencer, proceed to step 3. If no
oil is present, install the air silencer and the engine
to air silencer hose; then start the engine.
NOTE: Prior to doing step 3, clean the air
silencer thoroughly.
3. Remove the coil cover; then unplug and remove
the coils.
4. Remove the spark plugs from the engine and cover
the spark plug holes with a rag. With the
emergency stop button in the down (OFF)
position, turn the ignition switch to the START
position.
5. 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
cylinders.
6. Install the spark plugs, coils, and coil cover; then
install the air silencer and the engine to air silencer
hose.
NOTE: The engine should now be safe to oper-
ate.

Low Oil Pressure
Warning Light
(660 cc Models)
The Low Oil Pressure Warning Light indicates engine oil
pressure, not the oil level; however, if the oil level is low,
it may affect oil pressure. The light should illuminate
each time the ignition switch is turned to RUN or START,
and it should go out when the engine starts. If the light
stays illuminated or it illuminates while the engine is run-
ning, oil pressure has been lost and the engine will auto-
matically shut off.
If oil pressure is lost, use the following procedure:
1. Check the oil level.
NOTE: To ensure an accurate reading, the snow-
mobile should be on level ground.
2. If the oil level is below the lower hole in the oil level
stick, add only enough recommended oil to raise the
level between the upper and lower holes. DO NOT
overfill the crankcase with oil.
Check Engine Light
(660 cc Models)
The Check Engine Light is controlled by the ECU and
may illuminate for a number of reasons. The light should
illuminate each time the key is turned to RUN or START,
and it should go out when the engine starts. If the light
stays illuminated or it illuminates while the engine is run-
ning, the ECU is receiving input that is outside of its
established parameters.
Preparation
For Storage
Prior to storing the snowmobile, it must be properly ser-
viced to prevent corrosion and component deterioration.
An authorized Arctic Cat Snowmobile dealer should per-
form this service; however, the owner/operator can per-
form this service if desired. To prepare the snowmobile
for storage, Arctic Cat recommends the following proce-
dure:
1. Clean the seat cushion with a damp cloth and
Arctic Cat Vinyl Protectant (p/n 0638-313).
2. Clean the snowmobile thoroughly by hosing dirt,
oil, grass, and other foreign matter from the skid
frame, tunnel, hood, and belly pan. Allow the
snowmobile to dry thoroughly. DO NOT get water
into any part of the engine.
3. Change the engine oil; then clean the air filter.
