Foreword, Safety, Basic Information
How to Read the Shop Manual
• Some of the attachments and options described in this shop manual may not be available in some areas. If
they are required, consult your Komatsu distributor.
• The materials and specifications are subject to change without notice.
• Shop Manuals are available for “machine part” and “engine part”. For the engine unit, see the shop manual
for the machine which has the same engine model.
• Actual machine may differ from the images which are contained in this manual. A typical model is shown in
the illustrations of this shop manual.
• The caution lamps, pilot lamps, and symbols of the switches on the machine monitor can be different in
accordance with the machine.
• For details of the symbols shown on the machine monitor, see Structure and Operation, “Caution
Lamps Shown on Machine Monitor” and “Pilot Lamps Shown on Machine Monitor”.
• For details of the switches of the machine monitor, see Testing and Adjusting, “Set and Operate Machine
Monitor”.
• For details of the switches, see the “Operation and Maintenance Manual”.
• All “AdBlue/DEF” shown on the machine monitor is referred to as “DEF” in the shop manual. Some machine
monitors installed to the product show “DEF” as “AdBlue/DEF” in the service mode. Thus, be sure to recognize
that “DEF” and “AdBlue/DEF” are the same when you read the shop manual.
REMARK
The illustrations in the shop manual reproduce the display of the machine monitor. They are not always the
same as the terminology in the shop manual.
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 Specification
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.
