GENERAL INFORMATION 1.5 2004 Four Stroke PWC Service Manual Service Guidelines -- Safety Warnings S Clean inside and outside of watercraft prior to servicing. Clean all parts before installing. Always use a service apron to prevent damage to footwell and top--deck fiberglass. S Watch for sharp edges which can cause personal injury. Protect hands and arms when working with sharp components. S Always use a soft--faced hammer and extreme care when removing difficult or stuck components. S Some fasteners are installed with locking agents or lubricants. Use of impact drivers will aid in fastener removal. S Always follow torques specifications located throughout manual. Fasteners secured with either too little or too much torque may fail and cause severe property damage, injury or death. S Always follow torque sequence patterns when found in this manual. Tighten each fastener evenly and to the specified torque value, and with specified locking agent. S Always use new gaskets, o--rings and seals, clips, cir--clips, and snap rings when assembling components. S Never re--use Nyloktor Flex Lockt nuts when assembling components. S Never re--use Oetikert clamps when removed from fuel lines. Replace with small gear clamps. S Always use Polaris--authorized lubricants, greases, and locking agents when assembling components. Failure to do so may cause severe engine or vehicle damage. S Always disconnect the black (--) negative cable first from the battery when removing the battery. When installing the battery, attach the red (+) positive cable first, then the black (--) negative cable. S Wear appropriate clothing, eye protection, and rubber gloves when working with batteries. Battery acid contains sulfuric acid and is extremely poisonous. Serious burns can result when in contact with skin, clothing, eyes or internal body components. S If battery acid is ingested, drink large quantities of water or milk. Follow with milk of magnesia, beaten egg or vegetable oil. Call a physician immediately. S Flush eyes for15 minutes with water and seek prompt medical attention if acid comes in contact with eyes. Thoroughly wash affected external body parts that come in contact with battery acid with water. S Keep hands, arms, legs, feet and hair away from rotating parts, hot engine and exhaust components, drive pump and impeller and engine induction when engine is running. S Never attempt engine or driveline inspections and/or repairs without first removing lanyard and battery cables. S Gasoline is highly flammable and explosive under certain conditions. Always exercise extreme care when handling gasoline. Do not smoke or allow open flames in or near the area where refueling is performed or where gasoline is stored. S Always refuel the watercraft outdoors and in a well--ventilated area. Do not fill the tank to the fuel cap. S If you get gasoline or oil on your skin or clothing, wash it off immediately with soap and water and change clothing.
