MAINTENANCE
Intake Filters
The intake foam filters limit snow
ingestion into the intake system. When
operating in loose powder snow, check
the foam filters periodically to remove
any accumulation of snow.
NOTICE: Operating the snowmobile with
the intake filters removed may
cause intake icing. The result will
be poor fuel economy or intake
malfunction. Always reinstall the
intake filters before operating the
snowmobile.
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 76.
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.
