MAINTENANCE
FUEL FILTER/FUEL LINES
This snowmobile is not equipped with an in-line fuel filter. The fuel pump uses a
sock-type pickup filter located within the fuel tank. This filter should only require
maintenance if debris or foreign material enters the fuel tank. Your POLARIS
dealer can provide service.
Contaminated or poor quality fuel may shorten the life of fuel system
components and result in poor engine performance. Always store fuel in clean
fuel containers. If low fuel pressure or reduced engine performance occurs, the
filter may need replacement. Your dealer can assist.
Inspect the fuel lines regularly for signs of deterioration or damage. Always
check fuel line condition after periods of storage. Normal deterioration from
weather and fuel compounds may occur. Replace worn or damaged fuel lines
promptly.
Kinking the fuel lines or using a pliers or similar tools to remove fuel lines may
cause damage to the lines. If a fuel line has been damaged or kinked, replace
SPARK PLUGS
SPARK PLUG RECOMMENDATIONS
A new engine can cause temporary spark plug fouling due to the preservative
added during the assembly process. Avoid prolonged idle speeds, which cause
plug fouling and carbonization.
Change the spark plugs at the intervals outlined on page 99.
• Use recommended spark plugs with the proper gap. Refer to the
specifications section for the specific spark plug to be used in your
snowmobile.
• Use only resistor-type spark plugs.
• Torque spark plugs to 18-22 ft. lbs. (24-30 Nm).
• Always carry spare spark plugs.
Using non-recommended spark plugs can result in serious engine damage. A
spark plug with a heat range too high will always cause engine damage if the
engine is operated in conditions more severe than intended for that plug.
Always use the spark plugs recommended for your snowmobile.
