1-2 GEN INFO E SAFETY WHILE WORKING SAFETY WHILE WORKING The procedures given in this manual are those recommended by Yamaha to be fol- lowed by Yamaha dealers and their mechanics. FIRE PREVENTION Gasoline (petrol) is highly flammable. Petroleum vapor is explosive if ignited. Do not smoke while handling and keep it away from heat, sparks, and open flames. VENTILATION Petroleum vapor is heavier than air and if inhaled in large quantities will not support life. Engine exhaust gases are harmful to breathe. When test-running an engine indoors, maintain good ventilation. SELF-PROTECTION Protect your eyes with suitable safety glasses or safety goggles when using com- pressed air, when grinding or when doing any operation which may cause particles to fly off. Protect hands and feet by wearing safety gloves or protective shoes if appropriate to the work you are doing. OILS, GREASES AND SEALING FLUIDS Use only genuine Yamaha oils, grease and sealing fluids or those recommended by Yamaha.

1-3 GEN INFO E SAFETY WHILE WORKING Under normal conditions of use, there should be no hazards from the use of the lubricants mentioned in this manual. How- ever, safety is all-important and by adopt- ing good safety practices, any risk is minimized. A summary of the most important precautions is as follows: 1. While working, maintain good stan- dards of personal and industrial hygiene. 2. Clothing which has become contaminated with lubricants should be changed as soon as practicable, and laundered before further use. 3. Avoid skin contact with lubricants; do not, for example, place a soiled wiping- rag in one’s pocket. 4. Hands, and any other part of the body which have been in contact with lubricants or lubricant-contaminated clothing, should be thoroughly washed with hot water and soap as soon as practicable. 5. To protect the skin, the application of a suitable barrier cream to the hands before working is recommended. 6. A supply of clean, lint-free cloths should be available for wiping purposes. GOOD WORKING PRACTICES 1. The right tools Use the special tools that are advised to protect parts from damage. Use the right tool in the right manner - don’t improvise. 2. Tightening torque Follow the torque tightening instructions. When tightening bolts, nuts and screws, tighten the larger sizes first, and tighten inner-positioned fixings before outer-positioned ones.
