E HOW TO USE THIS MANUAL 1 The main points regarding removing/installing and disassembling/assembling procedures are shown in the exploded views. 2 The numbers in the exploded views indicate the required sequence of the procedure and should be observed accordingly. 3 Symbols are used in the exploded views to indicate important aspects of the procedure. A list of meanings for these symbols is provided on the following page. 4 It is important to refer to the job instruction charts at the same time as the exploded views. These charts list the sequence that the procedures should be carried out in, as well as pro- viding explanations on part names, quantities, dimensions and important points relating to each relevant task. Example: O-ring size 39.5 × 2.5 mm: inside diameter (D) × ring diameter (d) 5 In addition to tightening torques, the dimensions of the bolts and screws are also men- tioned. Example: Bolt and screw size : bolt and screw diameter (D) × length (L) 6 In addition to the exploded views and job instruction charts, this manual provides individ- ual illustrations when further explanations are required to explain the relevant procedure. d D 10 × 25 mm D L

1-2 GEN INFO E SAFETY WHILE WORKING SAFETY WHILE WORKING 1 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 and keep it away from heat, sparks and open flames. 1030 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. 1040 SELF-PROTECTION Protect your eyes with suitable safety glasses or safety goggles, 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. 1050 OILS, GREASES AND SEALING FLUIDS Use only genuine Yamaha oils, greases and sealing fluids or those recommended by Yamaha. 1060
