MAINTENANCE

Intake Filters

The intake foam filters 
limit snow ingestion into 
the intake system. When 
operating in loose powder 
snow, check the foam fil-
ters periodically to 
remove any accumula-
tion of snow.

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

See your POLARIS dealer for replacement of the fuel filter at the inter-
vals outlined in the Periodic Maintenance Table beginning on page 78.

Contaminated or poor quality fuel will shorten the life of the fuel filter 
and result in poor engine performance. Always store fuel in clean fuel 
containers. If low fuel pressure or reduced engine performance occurs 
between the recommended fuel filter service intervals, the filter may 
need replacement. See your dealer.

Inspect the fuel lines regularly for signs of deterioration or damage. 
Always check fuel line condition after periods of storage. Normal dete-
rioration from weather and fuel compounds may occur. Replace worn or 
damaged fuel lines promptly.

NOTICE: 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 it promptly.
