1-2 E GEN INFO 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 gasoline (petrol) and keep it away from heat, sparks, and open flames. VENTILATION Petroleum vapor is heavier than air and is deadly if inhaled in large quantities. Engine exhaust gases are harmful to breathe. When test-running an engine indoors, maintain good ventilation. SELF-PROTECTION Protect your eyes with suitable safety spec- tacles or safety goggles when grinding or doing any operation which may cause parti- cles 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, greases, and sealing fluids or those recommended by Yamaha.
