1 Safety while working To prevent an accident or injury and to pro- vide quality service, observe the following safety procedures. Rotating part • Hands, feet, hair, jewelry, clothing, personal flotation device straps, and so on, can become entangled with internal rotating parts of the engine, resulting in serious injury or death. • Keep the top cowling installed whenever possible. Do not remove or install the top cowling when the engine is running. • Only operate the engine with the top cowling removed according to the specific instructions in the manual. Keep hands, feet, hair, jewelry, clothing, personal flotation device straps, and so on, away from any exposed moving parts. Hot part During and after operation, engine parts are hot enough to cause burns. Do not touch any parts under the top cowling until the engine has cooled. Electric shock Do not touch any electrical parts while start- ing or operating the engine. Otherwise, shock or electrocution could result. Propeller Do not hold the propeller with your hands when loosening or tightening the propeller nut. Handling of gasoline • Gasoline is highly flammable. Keep gasoline and all flammable products away from heat, sparks, and open flames. • Gasoline is poisonous and can cause injury or death. Handle gasoline with care. Never siphon gasoline by mouth. If you swallow some gasoline, inhale a lot of gasoline vapor, or get some gasoline in your eyes, see your doctor immediately. If gasoline spills on your skin, wash with soap and water. If gasoline spills on your clothing, change your clothes. Ventilation • Gasoline vapor and exhaust gas are heavier than air and extremely poisonous. If gasoline vapor or exhaust gas is inhaled in large quantities, it may cause loss of con- sciousness and death within a short time. • When test running an engine indoors (for example, in a water tank) make sure to do so where adequate ventilation can be main- tained. General information

2 Self-protection • Protect your eyes by wearing safety glasses or safety goggles during all opera- tions involving drilling and grinding, or when using an air compressor. • Protect your hands and feet by wearing protective gloves and safety shoes when necessary. Working with crane • Outboard motors weighing 18.0 kg (39.7 lb) and over must be carried by a crane. • Use the wire ropes of adequate strength, and lift up the outboard motor using the three point suspension. • If the outboard motor does not have three or more points to be suspended, support it using additional ropes, or the like, so that the outboard motor can be lifted and carried in a stable manner. Handling of gas torch • Improper handling of a gas torch may result in burns. For information on the proper handling of the gas torch, see the operation manual issued by the manufacturer. • When using a gas torch, keep it away from the gasoline and oil, to prevent a fire. • Components become hot enough to cause burns. Do not touch any hot components directly. Part, lubricant, and sealant Use only genuine Yamaha parts, lubricants, and sealants, or those recommended by Yamaha, when servicing or repairing the outboard motor.
