MAINTENANCE
Extended Storage
Engine and Carburetor Protection
Proper preparation of the engine and fuel system is vital to the
prevention of rust and corrosion on precision engine parts during
storage. Whenever the machine is stored for a period of more than 60
days,the engine must be fogged with fogging oil. Follow the engine
fogging instructions provided on the can. See page 99.
Always add Premium Carbon Clean or a fuel conditioner/stabilizer to
the fuel tank. See page 99 for the part numbers of Polaris products.
Follow the instructions on the can, running the engine for five minutes
to get additives through the entire fuel system. Top off with fresh
premixed fuel.
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
following procedure.
1. Transfer unused fuel from the fuel tank to an approved fuel
container 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
cylinder models, the opposite piston will be up.
5. Pour approximately two ounces of Polaris injection oil into the
spark plug hole.
6. Wait one to two minutes and perform steps 3 to 5 on remaining
cylinders.
7. Replace the spark plugs and lower the machine to the floor.
