MAINTENANCE Fuel Filter/Fuel Lines See your POLARIS dealer for replacement of the fuel filter at the intervals outlined in the Periodic Maintenance Table beginning on page 65. 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 deterioration 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. Cooling System Inspect the fan intake and outlet ducts for cracks, blockage, obstructions, damaged seals or loosening of the ducts. Make any necessary repairs promptly. Exhaust System Check the exhaust system for wear or damage at approximately 2000 miles (3200 km). Always allow the engine and exhaust system to cool completely before inspecting. CAUTION! Hot exhaust system parts can cause burns. Allow adequate time for the exhaust system to cool. Never perform this procedure with the engine running. 1. Open the side panels and remove the hood. See page 68. 2. Inspect the muffler and pipes for cracks or damage. 3. Check for weak or missing retaining springs or damper/support grommets. 74
