Storage

Off season or extended storage of your snowmobile requires preventive measures to aid against deterioration and to prolong the useful life of many components.

Fog the Engine

Treat the fuel system with POLARIS Carbon Clean. See Stabilize the Fuel.
Support the front end of the machine so the engine is level or tilted slightly rearward.
Turn the fuel valve off.
Remove the spark plug.
Spray fogging oil into the cylinder.
Slowly pull the recoil starter to turn the engine over two or three times.
Reinstall the spark plug.
Rotate the piston to bottom dead center (BDC) and
Slowly pull the recoil starter handle until resistance is felt. Leave it in that position.
Clean the engine thoroughly with an oiled cloth.

Polaris Fogging Oil

(12 oz aerosol can)

Part Number: 2870791

NOTICE

If POLARIS fuel system additive is not used, the fuel tank, fuel lines, and carburetor should be completely drained of gasoline. Observe all fire safety rules when draining the carburetor. Review the fuel-related warnings on Fuel. To eliminate any fuel remaining in the carburetor, run the engine until it stops.

Stabilize the Fuel

Proper off-season preparation of the engine and fuel system is vital to the prevention of rust and corrosion formation on precision engine parts during storage.

Fill the fuel tank with fresh fuel.

Add POLARIS Carbon Clean Fuel Treatment or POLARIS Fuel Stabilizer. Follow the instructions on the container for the recommended amount.

TIP

Carbon Clean removes water from fuel systems, stabilizes fuel and removes carbon deposits from pistons, rings, valves and exhaust systems.

Start the engine. Allow it to idle for five minutes to disperse additives through the entire fuel system.
Turn the fuel valve off.

Track and Suspension

Support the rear of the snowmobile slightly off the ground with an appropriate snowmobile support. This will allow the track to hang freely.

Elevate the front end of the machine and place blocks securely under it to remove tension from the shocks and springs. This will minimize fatigue on the front shocks and springs.

Storage Area

Your snowmobile should be stored in a dry garage or shed, out of direct sunlight. It should be covered with a fabric snowmobile cover. Plastic covers can cause condensation to form and may damage some snowmobile components.
