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 (P/N 413 802 900
— 12 x 1 L), 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.
