3. Foreword
Target group This Service Manual has been written for those whose job it is to ensure that
the machines remain operational on a daily basis. This includes the
mechanics and workshop specialists at Liebherr branch offices and Dealers.
Contents In the first chapter you will find information about safety regulations as well
as specifications for the special tools needed for maintenance and repair.
Chapter 2 provides an overview of important technical data for the entire
machine and the individual assemblies.
The following chapter, entitled Maintenance, contains the maintenance and
inspection schedule, testing and adjustment schedule, lubrication chart and
filling quantities, a description of maintenance procedures and specifications
for prescribed lubricants and fuels.
The technical description of the machine in the following chapters is divided
into 15 function groups. The design, function, and technical data for each
component and part are explained.
Chapter 19 is a new one and in it, you will find a list of available repair
manuals, troubleshooting hints, the service code table and a description of
the BODEM service software.
How to use this manual This manual describes a variety of machine types as well as optional
equipment. In general, this information applies to the types and serial
number groups specified in the footnotes. One exception is that specific type
and serial number data are indicated at the beginning of each section (e.g.
the technical specifications of the components).
Whenever possible, parts and components are supplemented by indication
of the identification number in the heading.
This manual is available in German, English and French.
Working instructions It is imperative that safety regulations be observed with all tasks done on the
machine. You will find information on this in the General Information
chapter.
A complete set of tools in perfect condition is required for work on the
machine, along with any special tools that might be needed. Absolute
cleanliness must be observed with all tasks!
Sealing material such as O-rings and surface seals should be replaced
whenever repairs are carried out.
CD edition We would particularly like to draw your attention to the fact that this book is
available not only in printed form, but also as an electronic document on CD.

1.1 Safety regulations
Working on the machine poses safety risks to the operator, driver or
maintenance technicians. Carefully reading and observing the various safety
instructions at regular intervals can considerably reduce the risk of accidents.
This is especially important for personnel who only occasionally work on the
machine, for example, carrying out repair or maintenance work. The safety
regulations listed below, if followed precisely, will ensure their safety and that
of others, and will prevent the machine from being damaged.
Whenever tasks, which could cause danger to personnel or damage to the
machine, are described, the necessary safety precautions will be explained.
These are indicated by the headings Danger, Warning or Caution.
1.1.1. Introduction
1. The symbols below have the following meanings:
Danger
Warning that without appropriate precautions, certain operational procedures
could result in fatal accidents.
Warning
Warning that without appropriate precautions, certain operational procedures
could result in severe physical injuries.
Caution
Warning that without appropriate precautions, certain operational procedures
could result in minor physical injuries or damage to the machine.
2. Observance of these instructions does not relieve you of the
responsibility to observe other rules and guidelines!
The following should also be observed:
– The safety rules enforced at the operating site
– Legally enforced traffic regulations
– Guidelines issued by trade associations

indicate the maintenance tasks, which fall into two main types.
The symbols have the following meanings:
Table with solid circle, box or star
– Here, the machine operator or his maintenance personnel are
responsible for carrying out maintenance tasks.
– This affects the maintenance intervals every 10 and 50 service hours (h)
and non-scheduled intervals.
The symbols have the following meanings:
Table with blank circle, box or star, or service hours (h)
– Here, authorised specialist technicians from LIEBHERR or its authorised
dealers must perform or direct maintenance and inspection work.
– This affects the maintenance intervals on delivery, every 500, 1000,
2000 service hours (h), and at unscheduled times.
You will find a list of the spare parts needed for maintenance and
inspection work in the SERVICE PACKAGE of the spare parts list.
