Foreword General
How to read the shop manual
Volumes
Shop manuals are issued as a guide to carrying out
repairs. They are divided as follows:
Chassis volume: Issued for every machine model
Engine volume: Issued for each engine series
These various volumes are designed to avoid dupli-
cating the same information. Therefore, to deal with
all repairs for any model , it is necessary that chas-
sis, engine, electrical and attachment volumes be
available.
Distribution and updating
Any additions, amendments or other changes will be
sent to KOMATSU distributors. Get the most up-to-
date information before you start any work.

cated by a hyphen (–) and number after the
