7) Tether Cut-Out Switch
Attach tether cord to clothing then snap tether cut-out cap over re-
ceptacle before starting engine.
To stop engine, completely pull cap from safety switch.
28) Primer Button
Pull and push button. It is not necessary when engine is warm.
To prime, activate button until a pumping resistance is felt. From this
point, pump 2 or 3 times to inject fuel in intake manifold. After prim-
ing, ensure that primer button is pushed back.
NOTE: In very cold temperature, it is recommended to rotate primer
button 3-4 turns prior to pull it. This will eliminate the possibility of
sticking.
29) Adjustable Toeholds
Each toehold can be adjusted to suit driver's preference. Loosen
bolts, adjust then, retighten bolts to 10 N•m (89 lbf•in).

FUEL AND OIL
Recommended Fuel
Use super unleaded gasoline, available from most service stations or
gasohol containing less than 10% of ethanol or methanol. The gaso-
line used must have an octane number (R + M)/2 of 91 or higher.
NOTE: In most service station pump octane number corresponds to
(R + M)/2 octane number.
When snowmobile is used in powder snow condition and/or at tem-
peratures from and below - 10°C (14°F), we highly recommend the
use of gas line antifreeze in a proportion of 150 mL (5 U.S. oz) of gas
line antifreeze added to 40 liters (10-1/2 U.S. gal) of gas.
This precaution is in order to reduce the risk of frozen carburetor(s)
which may lead, in certain cases, to high fuel consumption or severe
damage to engine.
NOTE: Use only methyl hydrate free gas line antifreeze, Kleen-
Flo™ or equivalent.
CAUTION: Never experiment with other fuels or fuel ratios. The
use of unrecommended fuel can result in snowmobile perfor-
mance deterioration and damage to critical parts in the fuel sys-
tem and engine components.
Recommended Oil
CAUTION: Never mix brands of 2-cycle oil as chemical reaction
can cause engine damage. Never use outboard or straight min-
eral oils. Use only oil that flows at - 40°C (- 40°F).
Use BOMBARDIER-ROTAX injection oil (P/N 413 802 900 — 12 x 1 L)
available from authorized dealer or suitable equivalent. This type of
oil will flow at temperatures as low as minus 40°C (- 40°F).
WARNING
Never top up the fuel tank before placing the snowmobile in a
warm area. As temperature increases, fuel expands and might
overflow. Fuel is flammable and explosive under certain con-
ditions. Always wipe off any fuel or oil spillage from the snow-
mobile.

STARTING PROCEDURE
• Re-check throttle control lever operation.
• Ensure that the emergency cut-out switch is in the ON position.
• Ensure the tether cut-out cap is in position and that the cord is
attached to your clothing.
• To prime, activate button until a pumping resistance is felt. From
this point, pump 2 or 3 times to inject fuel in intake manifold. After
priming, ensure that primer button is pushed back.
NOTE: In very cold temperature, it is recommended to rotate primer
button 3-4 turns prior to pull it. This will eliminate the possibility of
sticking.
NOTE: Priming is not necessary when engine is warm.
