MAINTENANCE
Extended Storage
Engine and Carburetor Protection
Using a fuel stabilizer and topping off the fuel tank eliminates the need
to drain the fuel system. If you prefer to drain the fuel tank, use the fol-
lowing procedure
1. Transfer unused fuel from the fuel tank to an approved fuel con-
tainer using a siphon pump. Do not re-use fuel after storage.
2. Securely support the front of the snowmobile with a jack stand so
the machine is elevated and the engine is tilted rearward.
3. Remove the spark plug(s).
4. Rotate the engine slowly, watching the piston until it's at bottom
dead center (BDC), the lowest position in the cylinder. On twin cyl-
inder models, the opposite piston will be up.
5. Pour approximately two ounces of Polaris injector oil into the spark
plug hole.
6. Wait one to two minutes and perform steps 3-5 on remaining cylin-
ders.
7. Replace the spark plugs and lower the machine to the floor.
