With
8ombardier-Rotax snowmobile
engines, a break-in period is required
before running the vehicle at full
throttle.
Manufacturer's, recommen-
dation
for the Bombardier-Rotax en-
gine
is 10to 15 operating hours. During
this period, a richer mixture is needed
Ii.e. 40 parts of gas
for
1 part
of
50 / 1
Bombardier snowmobile oil). Maximum
throttle should
not
exceed
%.,
how-
everI brief full acceleration and speed
variations contribute to a good break-
in. Continued wide open throttle accel-
erations, prolonged cruising speeds,
and lugging are detrimental during the
break-in period.
After the break-in period, each snow-
mobile must have an inspection check.
This inspection is at the expense of the
vehiele owner.

Oil must be added to the gasoline in
pre-measured amounts then both
oil
and gasoline should be thoroughly
mixed together before fueling the tan k.
The correct gasoline is premium gaso-
line, available from all service stations.
• CAUTION: _Never experiment
with different fuel or fuel ratios.
Never use
low
lead or non leaded gaso-
line, naphta, methanol or simular
products.
Use concentrated Bombardier
snow-
mobile oil available from your dealer.
This type of oil has specially formu-
lated oil bases to meet the lubrication
requirements of the Bombardier-Rotax
engine.
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.
..
CAUTION: Never use ouboard
...
or straight mineral oils.
The importance of using the correct fu-
el mixture cannot be overstressed. An
incorrect fuel ratio results in serious en-
gine damage. Recommended fuel ratio
is 50/ 1.
5 gallons recommended gasoline plus 1
can of
50/
1concentrated Bombardier
snowmobile oil
=correct fuel mixture.

NOTE: To facilitate fuel mixing,
oil should be kept at room
rature.
