2 CHAPTER ONE ) cusses the tools and techniques for preventive f7"\ maintenance, troub leshooting and repair. 0 Chapter Two provides methods and suggestions for quick and accurate problem diagnosis and repair. Troub le- shooting procedures discuss typical symptoms and logical methods to pinpoint the trouble. Chapter Three explains all per iodic lubrication and rou- tine maintenance necessary to keep the engine operating well. Chapter Three also includes recommended tune-up procedures, eliminating the need to constantly consult other chapters on the various assemblies.
Subsequent chapters describe specific systems, provid- ing disassembly, repair, assembly and adjustment proce- f:\2 dures in simple step-by-step fonn. If a repair is \.V impractical for a home mechanic, it is so indicated. It is usually faster and less expensive to take such repairs to a dealer or repa ir shop. Spec ifications conce rning a specific system are included at the end of the appropriate chapter. NOTES, CAUTIONS AND WARNINGS The terms NOTE, CAUTION and WARNING have specific meanings in this manual. A NOTE provides addi- tional information to make a step or procedure easier or clearer. Disregarding a NOTE could cause inconvenience but would not cause damage or personal injury.
A CAUTION emphasizes areas where equipment dam- age could occur. Disregarding a CAUT ION could cause permanent mechanical damage; however, personal injury is unlikely. A WARNING emphasizes areas where personal in jury or even death could result from negligence. Mechanical damage may also occur . WARNINGS are to be taken seri- ously. In some cases, serious injury or death has resulted from disregarding similar warnings. 5. When replacing a fastener, make sure to use one with the same measurements and strength as the old one. Incor- rect or mismatched fasteners can result in damage to the engine and possible personal injury.
Beware of fastener kits that are filled with poorly made nuts, bolts, washers and cotter pins. Refer to Fasteners in this chapter for addi- ti ona l informa tion. 6. Keep all hand and power tools in good condition. Wipe greasy and oily tools after using them. They are difficult to hold and can cause injury. Replace or repair worn or damaged tools . 7. Keep the work area clean and uncluttered. 8. Wear safety goggles (Fi g ure 1) during all operations involving drilling, grinding, the use of a cold chisel or any time the safety of the eyes is compromised. Safety gog- gles should be worn when using solvent and compressed air. 9. Keep an approved fire extinguisher nearby (Figure 2).
Make sure it is rated for gasoline (Class B) and electrical (Class C) fires . 10. When drying bearings or other rotating parts with compressed air, never allow the air jet 10 rotate the bearing or part . The air jet is capable of rotating them at speeds far SA FE TY FIRST Professional mechanics can work for years and never sustain a serious injury. By observing a few rules of com- mon sense and safety, it is poss ible to enjoy many safe hours servicing the machine. Ignoring these rules can cause injury or damage to equipment. I. Never use gasoline as a cleaning solvent. 2. Never smoke or use a torch in the vicinity of flamma- ble liquids, such as cleaning solvent, in open containers. 3.
Use prope r sized wrenches to avoid damage to fasten- ers and personal injury. 4. When loosening a tight or stuck nut, remember what could happen if the wrench should slip. Be careful; protect yourself accordingly.
