bile is tilted on its side or if the ambient tempera-
ture rises, causing the fuel to warm up and
expand.

Engine oil level

The engine oil level should be checked before each use.

CAUTION:

@ 

Do not run the engine with too much or not enough
oil in the oil tank. Oil could flow into the air filter case
and the engine could be damaged. 

@

Checking 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.

3. Disconnect the oil level gauge coupler 

1.

CAUTION:

@ 

Disconnect the oil level gauge coupler before remov-
ing the oil level gauge/dipstick. Otherwise the cable
can twist and become severed. 

@

4. Remove the oil level gauge/dipstick 

2, wipe it clean,

insert it back into the filler hole (without screwing it
in), and then remove it again to check the oil level.

NOTE:

@ 

The engine oil should be between the “F” 

3 and “E” 4

level marks on the oil level gauge/dipstick. 

@

5. If the engine oil is below the “E” level mark, add suffi-

cient oil of the recommended type to raise it to the “F”
level mark. (See page 6-2 for recommended oil.)

CAUTION:

@ 

●

When adding the engine oil, be careful not to fill
above the “F” level mark on the oil level
gauge/dipstick. 

●

Make sure that no foreign material enters the
engine oil tank. 

@

6. Insert the oil level gauge/dipstick into the oil filler

hole, and then tighten it securely.

7. Connect the oil level gauge coupler.
