GEN INFO General information 1-3 69J1D11 Safety while working 1 To prevent an accident or injury and to ensure quality service, follow the safety procedures provided below. Fire prevention Gasoline is highly flammable. Keep gasoline and all flammable products away from heat, sparks, and open flames. Ventilation Gasoline vapor and exhaust gas are heavier than air and extremely poisonous. If inhaled in large quantities they may cause loss of consciousness and death within a short time. When test running an engine indoors (e.g., in a water tank) be sure to do so where ade- quate ventilation can be maintained. Self-protection Protect your eyes by wearing safety glasses or safety goggles during all operations involv- ing drilling and grinding, or when using an air compressor. Protect your hands and feet by wearing protective gloves and safety shoes when neces- sary. Parts, lubricants, and sealants Use only genuine Yamaha parts, lubricants, and sealants or those recommended by Yamaha, when servicing or repairing the outboard motor. Under normal conditions, the lubricants men- tioned in this manual should not harm or be hazardous to your skin. However, you should follow these precautions to minimize any risk when working with lubricants. 1. Maintain good standards of personal and industrial hygiene. 2. Change and wash clothing as soon as possible if soiled with lubricants. 3. Avoid contact with skin. Do not, for example, place a soiled rag in your pocket. 4. Wash hands and any other part of the body thoroughly with soap and hot water after contact with a lubricant or lubricant soiled clothing has been made. 5. To protect your skin, apply a protective cream to your hands before working on the outboard motor.

69J1D11 1-4 1 2 3 4 5 6 7 8 9 6. Keep a supply of clean, lint-free cloths for wiping up spills, etc. Good working practices Special tools Use the recommended special tools to protect parts from damage. Use the right tool in the right manner—do not improvise. Tightening torques Follow the tightening torque specifications provided throughout the manual. When tightening nuts, bolts, and screws, tighten the large sizes first, and tighten fasteners starting in the center and moving outward. Non-reusable parts Always use new gaskets, seals, O-rings, cot- ter pins, circlips, etc., when installing or assembling parts. Disassembly and assembly 1. Use compressed air to remove dust and dirt during disassembly. 2. Apply engine oil to the contact surfaces of moving parts before assembly. 3. Install bearings with the manufacture identification mark in the direction indi- cated in the installation procedure. In addition, be sure to lubricate the bearings liberally. 4. Apply a thin coat of water-resistant grease to the lip and periphery of an oil seal before installation. 5. Check that moving parts operate nor- mally after assembly.
