YOUR KEY
TO WINTER
In the past sixteen years, over seven million people have
discovered
that winter can be both fun and enjoyable. The key of
course is to do as
you have done ... participate in the exciting,
invigorating sport of snowmobiling. We commend
your decision,
and
thank you for selecting the Ski-Doo snowmobile as your
partner in the many winter seasons to come.
To
truly enjoy this wonderful sport, we urge you to join your
local snowmobile club. You will find its activities and trail
systems are planned
for both fun and safety.
If your area does not have such benefits, you can find added
social
enjoyment by forming a new club and assisting with the
layout, construction and marking of a snowmobile trail. You
will find the activities both stimulating and rewarding. And only
you can make it happen.
We also suggest
that you enroll in a safety/driver education
program. The benefits derived are invaluable
toward the safe and
saneoperation of any snowmobile.
We, at Bombardier
Limited, fully realize the ramifications
associated with the sport, and toward this end this manual is
prepared.
Please take the time to have every member of your
family read and fully understand the content of this manual ...
Ride safe ... and have fun!
Laurent Beaudoin,

With Ski-Doo snowmobiles, the oil must
be added to the In pre-mea-
sured
amounts then both oil and gaso-
line should be mixed to-
gether before the tank
Which Gasoline to Usa
The correct gasoline is gasoline.
(not less than 92 octane), available
from
all service stations.
Cautio!"!: Never experiment with other
than recommended fuels or fuel ratios.
Never use no lead
methanol or similar products.
Which OJ! to Use
Use concentrated Ski-Doo oil available
from your Ski-DOG dealer. This type of
oil has specially
formulated oil bases to
meet
the lubrication requirements of the
Bombardier-Rotax
enouqh ~h0rf.lL:.Hl'! we do nor recommend
no lead 9a501'085
Caution: The carburetors of the Ski-Doo
snowmobile have been calibrated for a
mixture of gasoline and concentrated Ski-
Doo oil.
Unless absolutely necessary, do
not use
regular snowmobile oil.
if such oil is used,
observe
mixing instructions on the con-
tainer, Never use outboard or straight
minerai oils,
fuel Mixing Ratio
The importance of using the correct fuel
mixture cannot be overstressed. Prior ex-
perience has shown
that an incorrect fuel
ratio results in serious engine damage,
The correct
fuel/oil ratio is 50!1
5recommended
can of 50!1 Ski-Doo
mixture.
Note: To facilitate fuel mixing, oi should
be kept at room temperature.
fuel Mixing Procechua
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. ei-
ther plastic or metal Draw from one un-
til empty then use the second one.
Warning: Gasoline is f!ammable and
explosive under certain conditions.
Always perform procedures in a well
ventilated area. Do not smoke or al-
low open flames or sparks in the vi-
cinity. If gasoline fumes are noticed
while driving, the cause should be
determined and corrected without
delay. Never add fuel whil4:l engine is
I'l.ll1ning.

1. Pour approximately one gallon of gaso-
line
into aclean container.
I . Add the full amount
of concentrated
Ski-Doo oil.
IiI. Shake the container thoroughly.
IV. Add the remainder of the gasoline.
V. Once again thoroughly the con-
tainer. Using a funnel a fine mesh
screen to prevent the
entry of water and
foreign particles, transfer
mixture from
container into the snowmobile tank.
Nota: When usmq pre-mixed fuel. al-
ways shake the
container thoroughly as
the oil has a
tendency to settle
Warning: Never 'top up' gas tank before
placing vehicle in a warm area. At certain
temperatures, gasoline will expand and
overflow.
Fuel Consumption
A good idea IS for you to rate the fuel
consumption of your snowmobile at the
first
opportunity Starting with a full fuel
tank, mark the time of your departure
then note
time elapsed until tank is
half-full. Repeat on different occasions
to get a mean average of your snow-
mobiles' consumption and length of
running
time under varYing conditions
With Ski-Doo snowmobile a
break-in period is required before running
the vehicle at
full throttle. Manufacturer's
recommendation for the Bombardier-
Rotax engine is 10 hours. Dur-
ing
this period, maximum throttle shou!d
not exceed 3/4. However, brief full accel-
erations and speed variations
contribute
to a good break-in. Continued wide open
throttle accelerations, 'cruis-
ing' speeds and ugging are detrimental
during the break-in period.
inspection
After the first 10 hrs of operation, each
Ski-Doo snowmobile must have an inspec-
tion check. This inspection is at the ex-
pense
of the vehicle owner.

fuel Tank Quantity
Check that there is sufficient fuel in the
tank for your tnp. Agood habit to ac-
quire is to refill
the tank before starting
out each day.
Since mixed fuel has a tendency to
settle overnight, agitate the fuel in the
tank by standing on
the footboards and
rocking the vehicle from side to side
Steering Operation
Check operation of steering mechanism
by moving the ski several times from
side to side. If roughness or binding is
felt, check for ice or snow that may be
blocking the mechanism.
Throttle and Brake
Depress and release levers several
times to check that they operate easily
and smoothly The
throttle lever should
return to the idle position when re-
leased The brake lever should be fully
applied
when It has minimum clearance
from the handlebar grip (see Main-
tenance, Brake). If the levers do not re-
turn swiftly. remove cables and/or
housings and replace. Re-check lever
operation.
Warning: Throttle mechanism
should be checked for free move-
ment before starting engine. Once
ail components are checked and
functioning properly, you can start
your Ski-Doo snowmobile.
Tips
By raising the outer attachment of the
bogie wheel sets vehicle manoeuverabil-
Ity in deep snow will increase You will
note
that there are partially dnlled
holes. located approx 1fa
fI above the
onginal cross shaft holes of the frame.
To reposition bogie wheel sets. dnll
holes fully through usmq a
716 fI dia drill
Remove capscrews securing bogie
wheel cross shafts to frame and reinstall
in
new position
Note: Once holes have been drilled.
both positions are interchangeable.
