OF REVISED PAGES will be added.
01. Specification
This section explains the specifications of the machine.
10. Structure and function
This section explains the structure and function of each component. It 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
This section explains the standard values for new machine and judgement criteria for testing, adjusting,
and troubleshooting. This standard value table is used to check the standard values in testing and adjusting
and to judge parts in troubleshooting.
30. Testing and adjusting
This section explains measuring tools and measuring methods for testing and adjusting, as well as the
adjusting method of each part. The standard values and judgment criteria for “Testing and adjusting” are
explained in “Standard value table”.
40. Troubleshooting
This section explains how to find out failed parts and how to repair them. The troubleshooting is divided
by failure modes. The “S mode” of the troubleshooting related to the engine may be also explained in the
Chassis volume and Engine volume. In this case, see the Chassis volume.
50. Disassembly and assembly
This section explains the special tools and procedures for removing, installing, disassembling, and assembling
each component, as well as precautions for them. In addition, tightening torque, and quantity and
weight of coating material, oil, grease, and coolant necessary for the work are also explained.
60. Maintenance standard
This section gives maintenance standard values of each component. The maintenance standard sub-section
explains the criteria and remedies for disassembly and service.
80. Appendix
This section explains the structure, function, testing, adjusting, and troubleshooting for the equipment not
classifiable in other sections.
