Pre-Start Check; Break-In Period - BOMBARDIER ski-doo Alpine 1972 Owner's Manual

PRE-START CHECK
Fuel Tank Quantity
Check that there is sufficient fuel in the
tank for your trip. A good habit to acquire
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 rotating the handlebars several. tirr:es
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 released. The
brake lever should be fully applied when
it is 1" (minimum clearance) from the
handlebar grip. If the levers do not return
swiftly, remove cables and/or
housl~gs
and replace. Re-check lever operation.
Do not start the engine
until
levers re-
turn swiftly.
WARNING: Always check throttle and
brake operation before starting engine.
YOU MAY NOW START YOUR SKI-
DOO SNOWMOBilE.

BREAK-IN PERIOD
With Ski-Doo snowmobile engines,
a break-in period is required before
running the vehicle at full throttle.
Manufacturer's recommendation for
the Bombardier-Rotax engine is ten
(10) operating hours or the equivalent
fuel consumption. (See page 3 for the
equivalent fuel consumption of your
vehicle). During this period. maximum
throttle should not exceed %, except
momentarily to attain cruising speed
or avoid emergency. Before you took
delivery of your new Ski-Doo snow-
mobile the carburetor was adjusted
by your Dealer for a rich fuelrnlxture.
This permits better lubrication .and
cooling of the engme. Do not readjust.
regardless of excessive smoke in the
exhaust.
Inspection
As with any precision piece of me-
chanical equipment. we suggest that
after the first 10 hours of operation or
30 days after purchase whichever
comes first, that each Ski-Doo snow-
mobile has an inspection check. This
inspection, which should take approx-
imately 1 V2 hrs., is at the discretion
and expense of the vehicle owner.
IMPORTANT: After the first 2 hours of
operation, check drive .chain tension.
(See Maintenance Section).
TIPS
• By raising the outer attachment of the
bogie wheel sets vehicle manoeuvera-
bility will increase.
You will note that there are partially drill-
ed holes. located approx. 1
%"
above the
original cross shaft holes of the frame.
(See Fig. 5). To reposition bogie
whe~)
sets, drill holes fully through usinq a
~6
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 interc.hangeable and
may be changed at any time.
• To start engine manually, when sta.rter
rope is broken. see Emergency GUide.
