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.
