SERVICE WARNINGS AND PRECAUTIONS

Service Warnings

When servicing the fuel system, it is
important to heed the following warnings.

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.
