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 carburetor icing. The result will be poor fuel economy or carburetor malfunction. Always reinstall the intake filters before operating the snowmobile. Oil Lines Inspect oil line condition every 1000 miles (1600 km).
