MAINTENANCE Intake Filter General Maintenance The intake foam filters limit snow ingestion into the intake system. When operating in loose powder snow, check the filters periodically to remove any accumulation of snow. 1. Airbox foam filter 2. Air intake box 3. Hood foam filters 3 1 2 CAUTION Operating the snowmobile without the intake filters may cause throttle body icing and result in poor fuel economy or throttle body malfunction. Always reinstall the filters before operating. Fuel Filter The best way to check the fuel filter is with fuel pressure. If fuel pressure is low, remove the filter and check pump pressure. If pressure is still low, the pump may need replacement. See your dealer. But if the pump pressure is good after removing the filter, then the fuel filter is plugged and must be replaced. The fuel filter should last the life of the machine if the fuel used is always of good quality. Fuel Lines Inspect the fuel lines regularly. Give special attention to the system's fuel line condition after periods of storage. Normal deterioration from weather and fuel compounds may occur. 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. 76
