CAUTION: Never experiment with
other fuels or fuel ratios. The use
of unrecommended fuel can result
in snowmobile performance deteri-
oration and damage to critical parts
in the fuel system and engine com-
ponents.
Fuel System Antifreeze
When using oxygenated fuel, addi-
tional gas line antifreeze or water
absorbing additives are not required
and should be not used.
When using non-oxygenated fuel, we
highly recommend the use of iso-
propyl base 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 frost buildup in carburetors
which may lead, in certain cases, to
high fuel consumption or severe dam-
age to engine.
NOTE: Use only methyl hydrate free
gas line antifreeze.
Fueling Procedure
Unscrew fuel tank cap to fill up tank
then fully tighten.

WARNING
Always stop the engine before re-
fueling. Fuel is flammable and ex-
plosive under certain conditions.
Always work in a well ventilated
area. Do not smoke or allow open
flames or sparks in the vicinity.
Open cap slowly.
If a differen-
tial pressure condition is noticed
(whistling sound heard when loos-
ening fuel tank cap) have vehicle
inspected and/or repaired before
further operation.
Do not over-
fill or top off the fuel tank before
placing the vehicle in a warm area.
As temperature increases,
fuel
expands and might overflow. Al-
ways wipe off any fuel spillage
from the vehicle. Periodically ver-
ify fuel system.
