ONOTE: indicates
information needed to
plete an instruction.
Although the mere reading of such in-
formation does not eliminate the haz-
ard, your understanding of the infor-
mation wilt promote its correct use.
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-
pect your desires, and that of others.
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.

restarting engine.
For
Elan models; unlock latches on

turn cab handles toward front of
vehicle. On Everest models; tift both
handles to disengage latches.
Located underthe cab. To gain access.
tilt cab. Ideal location for spare pluqs,
belt rope, etc. Spark plugs and other
breakable emergency items should be
wrapped in foam or similar material.
This will prevent possible breakage
while travailing over rough or
bumpy
terrain.
..... WARNING: Never us. e a lighted
T match or open flame to check
fuel level.

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.

2. Add the full amount of oil.
To mix the gasoline and oil always use
aseparate clean container. Never mix
directly in your snowmobile tank. For
best results, acquire
two containers/ ei-
ther plastic or metal. Draw from one
untilernptv then use the second one.
.... WARNING: Gasoline is flamma-
... ble and explosive under certain
conditions. Always perform pro-
cedures in a weH ventilated area.
Do not smoke or allow open
flames or sparks in the vicinity. If
gasoline fumes are noticed while
driving, the cause should be de-
termined and corrected without
delay. Never add fuel while engi-
ne is running. Avoid skin contact
with fuel at below freezing tem-
peratures.
1. Pour approximately one gallon of
gasoline into a clean container.
3. Replace container cap and shake
the container thoroughly.
4. Add the remainder of the gasoline.
5. Once again thoroughly agitate the
container. Then using a funnel
with
a fine mesh screen to prevent the
entry of water and foreign particles,
transfer mixture from container into
the snowmobile tank.
a
NOTE: When using pre-mixed
fuel, always shake the container
thoroughly as the oil has a ten-
dency to settle.
.... WARNING: Never 'top up' gas
... tank before placing vehicle in a
warm area. At certain tempera-
tures, gasoline
will expand and
overflow.

During normal driving, snow will act as
alubricant and coolant for the slider
shoes. Extensive riding on ice or sand-
ed snow, (not to mention dirt, asphalt,
etc. never recommended) will create
excessive heat build-up and cause pre-
matureslider shoe wear.
At cold temperature and / or when
the vehicle is operated in powdered
snow, the air intake silencer
elbow
must be turned toward the rear of the
vehicle. The elbow may be turned to
the front of the vehicle only when the
vehicle is operated at warm tem-
perature.

Routine maintenance is necessary for
all mechanized
products, and the
snowmobile is no exception. A weekly
vehicle inspection contributes to the
life span of the snowmobile as well as
retain safe and trouble-free operation.
It is recommended that the steering
system and suspension, be lubricated
monthly or every 40 hours of opera-
tion. If the vehicle is operated in wet
snow or in severe conditions these
items should be lubricated more fre-
quently.
•WARNING:
Only perform such
procedures as detailed inthisma-
nual. Unless otherwise specified,
engine should be turned OFFfor
all lubrication and maintenance
procedures.
For any procedure that may require re-
moval of console, proceed as follows:

Lubricate the suspension bogie wheels
using
low temperature grease. Pump
through the grease fitting at center of
each wheel until new greaseappears at
the joint of inner side of shaft. Lubri-
cate the rearaxlewith low-temperature
grease. Pump through

tings.
IMPORTANT: The drive pulley assem-
bly will be excluded from warranty, if
the factory seal is broken by other than
a duly authorized representative of
Bombardier.
On
Elan and Olympique 300 mono cy-
linder models, the drive pulley requires
lubrication bi-monthly or every 20 hrs.
of operation. All other models1covered
in this manual do not require lubrica-
tion.
.& WARNING: Thefubrication of
~ the drive pulley should be per-
formed only by an authorized
Ski-Doo dealer. Adisassembly,
cleaning, inspection and lubri-
cation where applicable should
also be performed by the dealer
every 100operating hours or at
the end of each season, which-
ever occursfirst.
CAUTION: Always use alow

cating
rear axle.
•
Using a low pressuregreasegun, lubri-
cate the five (5) idler wheels, four (4)
