Owner's Operation and Maintenance Manual

MAINTENANCE
Front Suspension
To minimize fatigue on the front shocks and springs during extended storage, it is
recommended that the front end of the machine be safely blocked off the ground
to remove tension from the shocks and springs.
Engine
Proper off-season preparation of the engine and fuel system is vital to the preven-
tion of rust and corrosion formation on precision engine parts during storage.
Without proper storage, jet restriction can cause lean conditions and very poor
slow speed driving quality.
When preparing your snowmobile for off-season storage, we recommend that you
add fuel conditioner/stabilizer or Premium Carbon Clean (PN2871326) to the fuel
tank. Follow the instructions on the can. Run the engine for five minutes to get ad-
ditives through the entire fuel system. Then top off the tank with fresh fuel.
NOTE: This procedure is performed best when the front of the machine is elevated
and the engine is tilted rearward.
Storage
Off season or extended storage of your snowmobile requires you to take preventa-
tive measures to aid against deterioration and to prolong the useful life of many
components.
Your snowmobile should be stored in a dry garage or shed, out of direct sunlight,
and covered with a fabric snowmobile cover. Plastic tarp can cause condensation
to form and may damage some snowmobile components.
Carburetor Protection During Off-Season Storage
When preparing your snowmobile for off-season storage we recommend that you
add a fuel conditioner/stabilizer or Premium Carbon Clean (2871326) to the fuel
tank. Follow the instructions on the can. Run the engine for five minutes to get ad-
ditives through the entire fuel system. Then top off with fresh fuel and turn the fuel
valveto“off.”
If stabilizer is not used, make sure the fuel valve is “off” and drain the carburetor.
Catch fuel in a container or shop cloth.
Remove the spark plug and pour approximately 5cc of engine oil into cylinder.
Slowly pull the recoil starter so the engine turns over two or three times. Reinstall
plug securely. Position piston at bottom dead center (BDC). Observe all fire safety
rules when draining carburetor. See gasoline warnings on page A--23.
Slowly pull the recoil starter handle until resistance is felt. Leave it in that position.
Clean the engine thoroughly with an oiled cloth.
If stabilizer is not used, turn the fuel valve to “off.” Remove the strainer cup, place
the strainer over a container, and open the strainer cock to discharge fuel from the
fuel tank. Remove the carburetor float chamber boltfrom thebottom and discharge
fuel from the carburetor. Replace bolt.
