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 10–15
minutes, and then turn it off.
TIP
● The engine can also be warmed up by driv-
ing the snowmobile for 10–15 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.
