4.2 Fuel Systems SERVICE WARNINGS AND PRECAUTIONS Service Warnings When servicing the fuel system, it is WARNING PROPOSITION 65 WARNING Snowmobile engines discharge fuel and exhaust which contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm, onto the snow on which they operate. Keep this engine properly tuned and avoid unnecessary idling and spillage during fueling. Do not smoke or allow open flames or sparks in or near the area where refueling is performed or where gasoline is stored or used. Do not overfill the tank past the bottom of the filler neck. If you get gasoline in your eyes or if you swallow gasoline, see your doctor immediately. Never start the engine or let it run in an enclosed area. Gasoline powered engine exhaust fumes are poisonous and can cause loss of consciousness and death in a short time. If you spill gasoline on your skin or clothing, immediately wash it off with soap and water and change clothing. CAUTION A main jet that is too small will cause a lean operating condition and may cause serious engine damage. Jet according to the jetting charts provided for each snowmobile. Most Polaris snowmobile engines are calibrated to run using 91 octane (oxygenated) or 89 octane (non- oxygenated) fuels. Polaris snowmobiles requiring higher octane fuel have the required octane level noted on the fuel tank filler cap. Never use fuel containing more than 10% ethanol or E85 fuels. All four fuel injectors must share the same color code (Yellow, Blue, or Red). 800 CFI engines use high flow injectors regardless of color coding. Always verify the fuel injector part number prior to installation. |
