Preface

Intended readership

Contents

This service manual is addressed to anyone whose task it is to ensure that the machines are ready for everyday use. This especially includes mechanics and workshop staff of Liebherr dealers and branches. The first chapter contains information on safety regulations and on the special tools needed for maintenance and repairs. Chapter 2 gives you an overview of all the most important technical data of the machine as a whole and its individual assemblies. Next comes the maintenance chapter, with the maintenance and inspection schedule, the testing and adjustment checklists, lubrication charts, description of maintenance tasks, testing and adjustment tasks and specifications of fuel and lubricants. The technical description of the machine is in the following chapters, structured according to fifteen function groups. The layout, function and technical data of the groups, components and parts are explained. Chapter 19 contains information on troubleshooting, the service code table and a description of the “SCULI” service software. Chapter 20 will be gradually updated with the latest options.

Instructions on use

This manual describes several types and versions of machines. The information generally applies to the types and serial numbers stated at the bottom of the page. The exception to this is information which only applies to specific types and serial numbers, which are stated at the beginning of the section concerned (for example technical data of parts). Where possible, the ID numbers of parts and components are stated in the heading. This manual is available in German, English, French, Spanish and Italian.

Working instructions

Always follow the safety regulations whenever you work on the machine. You will find a reference to this in the “General Information” section. In order to perform these tasks you need a complete set of basic tools andcertain special tools, all in perfect working order. All tasks require absolute cleanliness. Replace seals such as O-rings and surface seals during repairs.

General Informations Safety regulations

1.1 Safety regulations Working on the machine poses safety risks to the operator, driver or maintenance engineers. You can prevent risks and accidents by regularly reading and observing the various safety instructions. This is especially important for personnel who only occasionally work on the machine, for example, carrying out rigging or maintenance work.

All work must be carried out only by qualified expert personnel or under the guidance and responsibility of such personnel. Qualified personnel are people, who: – on the basis of their education, experience and training have sufficient knowledge of earth moving machinery and the technology, – have in-depth knowledge of the regulations concerning the prevention of industrial accidents and of national regulations and guidelines, – can assess the safe operating condition of earth moving machinery, – can carry out the required work without putting those carrying out the work, or other parties, into danger. Whenever tasks which could cause danger to personnel or damage to the machine are described, the necessary safety precautions are explained in this manual. These are indicated by the headings Danger, Warning, Caution or Notice.
