Be sure to change the engine oil after
G
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-
G
placed every 20000 km (12000 mi) of op-
eration. Have a Yamaha dealer replace
the oil filter cartridge.
To check the engine oil level
1. Place the snowmobile on a level surface
and apply the parking brake.
2. Start the engine, warm it up for 10–15
minutes, and then turn it off.
TIP
The engine can also be warmed up by op-
G
erating the snowmobile for 10–15 minutes.
After operating the snowmobile, allow the
G
engine to idle for at least 10 seconds before
turning it off.
3. Remove the shroud and the right side
cover. (See page 41 for removal proce-
dures.)
