operating in loose powder snow, check
the foam filters periodically to remove
any accumulation of snow or ice.
FUEL PUMP
All fuel pump service must be performed by an authorized POLARIS dealer. Do
not attempt to service the fuel pump.
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. An authorized
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. An authorized 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
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.
