Break-in
There is never a more important period in the
life of your engine than the period between 0
and 500 km (300 mi). For this reason, you
should read the following material carefully.
Since the engine is brand new, do not put an
excessive load on it for the first 500 km (300
mi). The various parts in the engine wear and
polish themselves to the correct operating
clearances. During this period, prolonged full-
throttle operation or any condition that might
result in engine overheating must be avoided.
Operating your snowmobile for the
first time
Start the engine and let it idle for 15 minutes.
0160 km (0100 mi)
Avoid prolonged operation above 6000 r/min.
160500 km (100300 mi)
Avoid prolonged operation above 8000 r/min.

mally.
NOTICE
