NOTICE
ECS00482
Do not run the engine with too much or
not enough oil in the oil tank. Oil could
spray out or the engine could be dam-
aged.
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 after the first 800 km (500 mi) of
operation, and every 20000 km (12000
mi) of operation thereafter.
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 1015
minutes, and then turn it off.
TIP
The engine can also be warmed up by driv-
ing the snowmobile for 1015 minutes.
After operating the snowmobile, allow the
engine to idle for at least 10 seconds before
turning it off.
3. Remove the shroud and the right side
cover (RS90GT / RS90LTGT /
RST90GT), or open the shroud (RST90).
[See page 63 (RS90GT / RS90LTGT /
RST90GT) or page 67 (RST90) for the
procedures.]
4. Disconnect the oil level gauge coupler.
NOTICE: Disconnect the oil level
gauge coupler before removing the oil
filler cap, otherwise the cable could
twist and break.
