Periodic maintenance and adjustment

●
Be sure to change the engine oil after
the first 800 km (500 mi) of operation,
and every 4000 km (2500 mi) thereafter
or at the start of a new season, other-
wise the engine will wear quickly.
●
The oil filter cartridge should be re-
placed every 20000 km (12000 mi) of op-
eration. Have a Yamaha dealer replace
the oil filter cartridge.

Place the snowmobile on a level surface

The engine can also be warmed up by op-

After operating the snowmobile, allow the
engine to idle for at least 10 seconds before
turning it off.
