THE YEAR
OF OUR MILLIONTH
MACHINE
Wewish J. Armand Bombardier could be around to see that
millionth machine come off the production line this year. What
would the inventor of the snowmobile think about todav's jet-
age styling? Or the incredible technical advances under the
sleek cowling? We think he'd be amazed - and proud.
In this year of the
millionth machine, J. Armand Bombardier
would have a lot to be proud about. First of all, a million is an
impressive number of machines. But there's something more
important than quantity. The Ski-Doo" line-up of today reflects
all the experience and know-how gained from the making of a
million machines.
At Bombardier, we've had time to learn all the tricks of
power and flotation. We've found out the pitfalls of operating
an engine in freezing conditions over every conceivable winter
terrain. And our experience shows. It shows in Ski-Doo" styling,
performance and dependability.
Another thing our founder wouldn't recognize is the factory.
From its start in a small garage, it's grown into the most advanced
snowmobile
factory in the world. Bombardier employs designers,
engineers, specialists and craftsmen by the thousand. They put
every Ski-Doo* through its paces, both in the versatile test labora-
tory, and on our outdoor speed track.
We've discovered
that the best testing ground of all is the race
track. We're in racing
not only to win, but to learn. This year,
we've been able to make some pretty impressive technical improve-
ments to all our machines -- improvements made on the track to
help
you on the trail.
It adds up to a machine you can depend on, all the time. Your
Ski-Doo" will give you excellent performance in all weathers, on
all terrains. Look after it well, and it will serveyou well. Your
Ski-Doo dealer is always ready with information, parts and acces-
sories. He is backed up by an international Ski-Doo distributor
and Dealer network whose factory trained personnel are equipped
to give you
prompt and efficient service wherever you are in
snow
country.
Ride safe ... and have fun!

To many of us. Winter IS a revealing ex-
perience Weather. atmospheric condi-
tions. snow surfaces. individual driving
habits and vehicle usage have consider-
able affects. We ask
that you familiarize
yourself
with them ... read the owner's
manual; it has been prepared to ac-
quaint you with the operation of your ve-
hicle. its safety aspects and systems as
well as preventative maintenance
procedures that must be periodically
upheld. ali aimed toward a more en-
jovable Winter season
Observe the precautions:
• Throttle mechanism should be
checked for free movement
before
starting engine.
• Engine should be running only when
pulley guard is secured In place.
• Never run engine without drive belt
installed. Running an unloaded engine
can prove to be dangerous.
eNever run the engine at high R.P.M.
when the tracks of the vehicle are raised
off the ground.
• It can be dangerous to run engine with
the cab open.
•Prolonged sitting while riding over
rough terrain may cause kidney
and/or
spinal discomfort. specially for the driver
or passenger having an existinq back
weakness
• Gasoline is flammable and explosive
under certain conditions. Always perform
procedures in a well ventilated
area. Do
not smoke or allow open flames or sparks
in the vicinity. If gasoline fumes are no-
ticed while driving, the
cause should be
determined and corrected
without delay.
eUnder no circumstances should you
wear loose or
scarves that
could become entangled With moving
parts of your snowmobile.
• Your snowmobile is not designed to
be operated on public streets. road or
highways. In most Statesand Provinces.
it
is considered an illegal operation.
•Hidden telephone guy wires or road-
side ditches can cause serious
accidents.
e Your snowmobile is not desiqnsd to
be driven or operated on black top. bare
earth, or other abrasive surfaces Abner-
mal and excessive wear of critical parts
is inevitable.
• Always wear an approved snow-
mobile safety helmet. Be informed on
local laws legislating the sport.
.. Maintain your vehicle in top mechani-
cal condition at all times.

Sitting-for all normal driving. Feet
should be on the footboards, body mid-
way back on the seat.
Avoid placing
your foot inside the support braces of
the footboard.
Warning: Prolonged sitting while riding
over rough terrain may cause kidney

tbe
driver or passenger having an existing
back weakness.
Turning.
To snowmobile properly you must learn
to
"body english", (using the weight or
position of your body) Shifting to left or
right as the turn demands and keeping
your center of gravity as low as possible
will give you the mark of an experienced
snowmobiler.
Moving your body
weight toward the
front of the vehicle, particularly in hard-
packed snow, adds pressure to the skis
and ski runners so that they bite more
deeply Into the
snow surface.
icy Surface.
Ice or extremely hard-packed snow can
be difficult to negotiate as
both skis and
track do not have
much traction. Best
advice is to slow
down and avoid rapid
acceleration or braking.
Deep Snow.
Use the standing position recom-
mended earlier and if your vehicle con-
tinues to make reasonable headway, re-
sponding to light changes In
acceleration, you are safe enough to ex-
plore
new areas. If not, turn in as wide
an arc as possible and look for firmer
trails.

With Ski-Doo snowmobiles. the oil must
be added to the gasoline in pre-mea-
sured
amounts then both oil and gaso-
line should be
thoroughly mixed to-
gether before fueling the tank
Which Gasoline to Use
On ali models except Olympique 400 the
correct gasoline is Regular gasoline, (not
less than 92 octane} available from all
service stations,
Due to the high compression
of the
Olympique 400 model, the correct
gas-
oline used is Premium gasoline,
Caution: Never experiment with other
than recommended fuels or fuel ratios
Never use no iead qasolinej .
methanol or simiiar products
tTests are not conclusive enough therefore wa
do
not recommend the use of no-!elld gasoiines.
Which Oil to Use
Use concentrated Ski-Doo oil available
from your Ski-Doo dealer. This type of
oi: has specially formulated oil bases to
meet the
lubrication requirements of the
Bombardier-Rotax engine.
Caution: The carburetors of the 1974
Ski-Doo snowmobile havebeen calibrated
for a mixture of ine and concen-
trated Ski-Doo oil.
Unless absolutely necessary. do not use
snowmobile
oil. if such oil is used,
observe instructions on the con-
tainer. Never use outboard or straight
mineral oils.
fuel Mixing Ratio
The importance of uSing the correct fuel
mixture cannot be overstressed. Prior
experience has
shown that an incorrect
fuel ratio results in senous engine dam-
age The correct fuel/oil ratio is 50/1
5 gallons recommended gasoline plus i
can of Ski-Doo concentrated oil == correct
fuel mixture.
Note: To facilitate fuel mixing, oil should
be at
room temperature.

1& IV
fuel Mixing Procedure
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 flammable and
explosive under certain conditions.
Always perform procedu res in a well
ventilated area. Do not smoke 01" al-
low open flames 01" sparks in the vi-
cinity. If gasoline fumes are noticed
while driving, the cause should be
determined and corrected without
delay. Never add fuel while engine is
l'l.Inning.
. Pour approximately one Ion of gas-
oline into aclean container.
2. Add the full amount of concentrated
Ski-Doo oil.
3. Shake the container thoroughly.
4. Add the remainder of the gasoline.
5. Once again thoroughly agitate the
container. Using a funnel
with afine
mesh screen to prevent the
entry of water
and foreign particles, transfer
mixture
from container into the snowmobile tank.
Note: When 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
Agood idea is for you to rate the fuel
consumption of your snowmobile at the
first
opportunity Starting with afull fuel
tank, mark the time of your departure
then note
time elapsed until tank is
half-full. Repeat on different occasions
to
get amean average of your snow-
mobiles' consumption and length of
running
time under varying conditions.

Fuel Tank Quantity
Check that there IS sufficient fuel in the
tank for your A good habit to ac-
quire IS to refill tank before Qt~lrtlnn

if the vehicle is

steering system should be lubricated more
frequently.
