Composition of shop manual:
• This shop manual describes the technical information required for the services performed in a workshop.
The shop manual is divided into the following chapters for the convenience of use.
00. Index and foreword
• This section includes the index, foreword, safety and basic information.
01. Specification
• This section explains the specifications of the machine.
10. Structure and function
• This section explains the structure and function of the machine. The section of “Structure and function”
serves not only to give an understanding for the structure of each component, but also serves as
reference material for troubleshooting.
20. Standard value table
• The standard values for a new machine and trouble shooting are indicated. This standard value table is
used for testing and adjusting, and determining a failure at troubleshooting.
30. Testing and adjusting
• This section describes the measuring tools and how to measure, and how to adjust various parts. As for
the standard value and failure criterion, see the standard value table.
40. Troubleshooting
• This section describes the troubleshooting in a suspected area when a failure occurs and the remedy for
the failure. Troubleshooting is described by each failure mode.
50. Disassembly and assembly
• This section explains the procedures for removing, installing, disassembling, and assembling each part or
component and the special tools for the works as well as precautions for doing them safely. In addition,
tightening torque, and quantity and weight of coating material, oil, grease, and coolant required for the
works are also explained.
60. Maintenance standard
• This section describes the maintenance standard values for each component. This section gives the
criterion values for each component and required remedy at disassembly or maintenance.
80. Appendix
• The structure and function, testing and adjusting, and troubleshooting for all of the other components or
equipment which can not be separately classified are explained together in the appendix.
90. Diagrams and drawings
• This section gives hydraulic circuit diagrams and electrical circuit diagrams.
