mation on carrying out repair work expertly.
Please go carefully through the
Technical Man-
ual
as well as the Owner’s Manual for the
hy-
draulic excavator
before starting any repair work.
Use the
Technical Manual
as well as the
Owner’s Manual
and

as a refer-
ence book and source of information even if you
are familiar with hydraulic excavator technology.
Using the Technical Manual, the experienced
construction machine mechanic can carry out any
necessary repairs expertly.

The Technical Manual is divided into eight sec-
tions and covers the originally delivered version of

Annex
The
Safety Instructions
section describes the
recommended procedures to be observed in order
to prevent any risk of accidents to the operator
and to the personnel responsible for the works
and for machine servicing measures.
The
Description of Functioning
section provides
technical information on operating the main de-
vices and systems.
The
Technical Data and Special Tools
section
lists service data, conversion tables and special
tools and servicing materials required.
The
Performance Testing
section gives the in-
formation required for carrying out performance
testing.
The
Troubleshooting
section contains informa-
tion on detecting faults in the machine.
The
Repair Instructions
section gives the techni-
cal information needed to carry out servicing and
repair work on the machine, describes the equip-
ment needed for servicing works, and provides
information on maintenance standards, removal
and installation procedures, and dismantling and
assembly procedures.
The required information can easily be found by
referring to the table of contents.
For reasons of clarity, some of the illustrations are
presented in simplified form. Differences from the
actual version at the hydraulic excavator are
therefore possible if this adds to the clarity of the
information.
Repair
Carry out any necessary repair work as soon as
possible. This reduces repair costs and increases
the availability of your hydraulic excavator.
When doing any work on the hydraulic excavator,
always observe the instructions given in the
Technical Manual and in the Owner’s Manual.
Extensive works not described in the Technical
Manual will gladly be executed for you by the O&K
after-sales service.
Always use
original spare parts
only.
