MAINTENANCE
Intake Filters
The intake foam filter (+) limits snow ingestion into the intake system.
When operating in loose powder snow, check the top of the foam filter
periodically to remove any accumulation of snow.
Fuel Filter/Fuel Lines
See your Polaris dealer for replacement of the in-tank fuel filter every
1000 miles (or annually).
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.
CAUTION
Operating the snowmobile with the intake filters removed may cause carbu-
retor icing. The result will be poor fuel economy or carburetor malfunction.
Always reinstall the intake filters before operating the snowmobile.
CAUTION
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.
