pre-measured amounts then both oil
and gasoline should be thoroughly
mixed together before fueling the tank.

leaded gasoline.
. . . CAUTION: Never experiment
.... with different fuel or fuel ratios.
Never use naphtha, methanol or similar
products.

mobile oil available from your dealer.
This type of oil has specially formula-
ted oil bases to meet the
lu
brication re-
quirements of the Bombardier-Rotax

If Bombardier snowmobile oil is un-
available, substitute with a high-quality
2 cycle snowmobile oil. The oil/gas
mix must meet the vehicle require-
ments. See oil manufacturer recom-
mendations on container .

Fuel Mixing Procedure
To mix the gasoline and oil always use
a separate clean container. Never mix
directly in your snowmobile tank. For
best results, acquire two containers,
either plastic or metal. Draw from one
until empty then use the second one.
.... WARNING: Gasoline is flamma-
~
ble and explosive under certain
conditions. Always manipulate in a
well ventilated area. Do not smoke or
allow open flames or sparks in the vici-
nity. If gasoline fumes are noticed
while driving, the cause should be de-
termined and corrected without delay.
Never add fuel while the engine is run-
ning. Avoid skin contact with fuel at
below freezing temperatures.
1. Pour approximately one gallon of
gasoline into a clean container.
2. Add the full amount
of
oil.
