Within the North American Continent,
there exist a very special breed
of peo-
ple... people
who enjoy ice and snow.
and the unexcelled trails
that lead to
virtually every corner of the snowbelt.
They enjoy too, the comfort of warm
clothinq, the friendliness of compan-
ions, and
the recreational vehicle that
made it all possible.; the Ski-Doo
snowmobile.
We, like millions of North American
families, have never forgotten our pio-
neer heritage/ or
our love of nature and
the great outdoors, consequently, we
have designed and engineered all
our
models with safety, comfort and quiet-
ness foremost in
our minds. We do res-

Information has been prepared to ac-
quaint the
owner /operator of a new
1977 snowmobile with the various ve-
hicle controls, owner-related mainte-
nance, and safe operating instructions.
This is accomplised via three manuals;
'The Snowmobile Safety Handbook'
'the Warranty and Consumer Guide
Booklet' and
the 'Operator Manual'.
Each is inseparable toward proper use
of the product, and should be kept
with the vehicle at all times.

With Ski-Doo snowmobile engines, a
break-in period is required before run-
ning the vehicle at full throttle. Manu-
facturers, recommendation for the
Bombardier-Rotax engine is 10 to 15
operating hours. During this period, a
richer mixtureis needed (i.e.40parts of
gas for 1part
of 50 I1Bombardier oil).
Maximum throttle should not exceed
%, however, brief full acceleration and
speed variations contribute to a good
break-in. Continued wide open throttle
accelerations, prolonged cruising
speeds, and lugging are detrimental
during the break-in period.
After the break-in period, each Ski-
Doo snowmobile should have an ins-
pection check. This inspection is at the
expense
of the vehicle owner.

on must be added to the gasoline in
pre-measured amounts then both oil
and gasoline should be thoroughly
mixed together before fueling the tank.
The correct gasoline is regular gasoline,
available from all service stations.
... CAUTION: Never experiment
'Y with different fuel or fuel ratios.
Neveruselow lead or non leaded
gasoline, naphta, methanol or si-
milar products.
8
Use concentrated Bombardier snow-
mobile oil available from your dealer.
This
type of oil has specially formulated
oil bases to meet the lubrification re-
quirements of the Bombardier-Rotax
engine.
If Bombardier snowmobile oil is un-
available substitute
with ahigh-quality
2cycle snowmobile oil. The oil/gas
mix must meet the vehicle require-
ments. See oil manufacturer recom-
mendations on container.
... CAUTION: Never use outboard
... 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 of regular gasoline plus 1
can
of 50/ 1concentrated Bombardier
snowmobile oil =correct fuel mixture.
O
NOTE: To facilitate fuel mixing,
oil should be kept at room tempe-
rature.
