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.
