VALMOMT

In 1957 and 1958, tests began on
what IS considered the forerunner of the
Ski-Doo' We experimented with many
different frames and
engines-in search
of a light
machine for one or two pas-
sengers By the fall of '58, the first pro-
totype was ready Initial tests made it
obvious the machine could hold ItS own
in the recreation market. Production be-
gan one year later and 225 machines
were sold at about $1
,000 each.
Like
it's predecessors the' 73 Ski-Doo
snowmobile is a combination of light-
ness, economy, strength and depend-
ability And yet,
with all this, it has one
other additional feature ... personality

com-
plexity of characteristics that distin-
guishes itself as part of a bold breed
... the Ski-Doo snowmobiles.

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
... all aimed toward a more en-
joyable
Winter season.
Observe the following 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.
•Never run the engine at high R.P.M.
when the track of the vehicle is 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 andIor
spinal discomfort, specially for the driver
or passenger having an existing back
weakness.
• Gasoline IS flammable and explosive
under certain conditions. Always per-
form procedures in a well ventilated
area Do not smoke or allow open
flames or sparks in the vicinity. If gaso-
line fumes are noticed while driving, the
cause should be determined and cor-
rected
without delay.
•Under no circumstances should you
wear loose clothing or scarves
that
could become entangled with moving
parts of your snowmobile.
•
Your snowmobile is not designed to
be operated on public streets, roads or
highways. In most States and Provinces,
it is considered an
illegal operation.
• Hidden telephone guy wires or road-
side ditches can
cause serious accidents.
• Your snowmobile is not designed to
be driven or operated on black top, bare
earth, or other abrasive surfaces Abnor-
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.

Fuel Mixing Procedure
To mix the and oil use a
separate container.
Never mix
directly in your snowmobile tank. For
best results, acquire
two containers,
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 procedures in awell
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
while engine is
running.
• Pour the full amount of Ski-Doooil re-
quired for the
total mixture into the
container.
• Add approximately half the amount of
Caution: The carburetors of the 1 973
Ski-Doo snowmobile have been cali-
brated for a mixture of and
concentrated Ski-Doo oil.
Unless do not use
regular oil. such oil IS
used, observe mixing instructions on the
container. Never use outboard or
straight mineral oils.
Fuel Mixing Ratio
The of the correct fuel
mixture cannot be overstressed. Prior
experience has shown that an incorrect
fuel ratio results in serious dam-
age. The correct
fuel/oil ratio 40/1

Note: To facilitate fuel m oil
should be kept at room temperature.
With Ski-Doo snowmobiles,

With Ski-Doo snowmobile engines. a
break-in period is required before fun-
ning the vehicle at full throttle. Manu-
facturer's recommendation for the
Bombardier-Rotax engine is 10 to 15
operating hours. During this period,
maximum throttle should not exceed 3,4.
However, brief full accelerations and
variations
contribute to a good

Inspection
After the break-in period, we suggest
that each Ski-Doo snowmobile has an
check. This
inspection is at
the discretion and expense of the ve~
hicle owner.
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
then note time elapsed until half-
full. Repeat on different
occasions to
get amean average of your snow-
mobiles' consumption and of

Fuel Tank Quantity
Check that there is sufficient fuel in the
tank for your trip. A good 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 mecha nism.
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
all 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 drilled
holes, located approx 1 ¥S 11 above the
original cross shaft holes of the frame.
To reposition bogie wheel sets, drill
holes fully through usmq a
5Ae 11 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.
