COLD WEATHER CARBURETION
MODIFICATIONS
All vehicles have been calibrated for - 20°C (- 4°F). They can be oper-
ated at warmer winter temperatures without problems.
CAUTION: For colder temperatures than - 20°C (- 4°F), carbure-
tor(s) must be recalibrated to avoid engine damage. Refer to an
authorized SKI-DOO dealer.
Refer also to RIDING AT HIGH ALTITUDES in following pages.
BREAK-IN PERIOD
Engine
CAUTION: A break-in period of 10 operating hours — 500 km
(300 miles) — is required before running the snowmobile at full
throttle.
During break-in period, maximum throttle should not exceed 3/4.
However, brief full acceleration and speed variations contribute to a
good break-in. Continued wide open throttle accelerations, prolonged
cruising speeds and engine overheating are detrimental during the
break-in period.
To assure additional protection during the initial engine break-in,
500 mL (18 imp. oz) of recommended injection oil should be added
to fuel for the first full filling of fuel tank. Always remove and clean
spark plugs after engine break-in.
Belt
A new drive belt requires a break-in period of 50 km (30 miles). Avoid
strong acceleration/deceleration, pulling a load or high speed cruising.
10-Hour Inspection
As with any precision piece of mechanical equipment, we suggest
that after the first 10 hours of operation — 500 km (300 miles) — or
30 days after the purchase, whichever comes first, your snowmobile
be checked by an authorized SKI-DOO dealer. This inspection will give
you the opportunity to discuss the unanswered questions you may
have encountered during the first hours of operation.
The 10-hour inspection is at the expense of the snowmobile owner.
