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.
0–160 km (0–100 mi)
Avoid prolonged operation above 6000 r/min.
160–500 km (100–300 mi)
Avoid prolonged operation above 8000 r/min.
500 km (300 mi) and beyond
The snowmobile can now be operated nor-
mally.

A snowmobile is a rider active vehicle, and
your riding position and your balance are the

well before attempting more difficult maneu-
vers.

enjoyable activity, providing you with hours of
pleasure. However, it is essential to familiar-
ize yourself with the operation of the snowmo-
bile to achieve the skill necessary to enjoy
riding safely. Before operating the snowmo-
bile, read this Owner's Manual completely

filter cartridge replaced.
If any engine trouble should occur dur-
ing the engine break-in period, immedi-
ately have a Yamaha dealer check the
snowmobile.
WARNING

ing operation.
Never put your feet outside the running

oughly familiar with your snowmobile
and all of its controls.
