Composition of the shop manual
This shop manual contains technical information necessary to perform services in workshops. It is divided into
the following chapters for the ease of use.
00 INDEX AND FOREWORD
This section describes the index, foreword, safety, and basic information.
01 SPECIFICATIONS
This section describes the specifications of the machine.
10 STRUCTURE AND FUNCTION
This section describes the structure and operation of each component with respect to each system. “STRUCTURE
AND FUNCTION” is helpful in not only understanding the structure of each component but performing troubleshooting.
20 STANDARD VALUE TABLE
This section describes the standard values for new machine and failure criteria for testing and adjusting, and
troubleshooting. Use the standard values table to check the standard values for testing and adjusting, and judge
troubles in troubleshooting.
30 TESTING AND ADJUSTING
This section describes the measuring tools and measuring methods for testing and adjusting as well as the adjusting
method of each part. The standard values and repair limit for TESTING AND ADJUSTING are described
in “STANDARD VALUE TABLE”.
40 TROUBLESHOOTING
This section describes troubleshooting of failure part and its remedy method on the occurrence of the failure.
Descriptions of troubleshooting are sorted by failure mode.
50 DISASSEMBLY AND ASSEMBLY
This section describes the special tools, work procedures, and safety precautions necessary for removal, installation,
disassembly, and assembly of the components and parts. In addition, tightening torques, quantity, and
weight of the coating materials, lubricants, and coolant necessary to these works are shown.
60 MAINTENANCE STANDARD
This section describes the maintenance standard value of each component. The maintenance standard shows
the criteria and remedies for disassembly and assembly.
80 THE OTHER INFORMATION
This section describes the structure and function, testing and adjusting, and troubleshooting for all of the other
components or equipment which cannot be separately classified in the appendix.
90 Circuit diagrams
This section describes hydraulic circuit diagrams and electrical circuit diagrams.
