Preface

Target group 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. Contents 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. 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 and French.

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 and certain special tools, all in perfect working order. All tasks require absolute cleanliness. Replace seals such as O-rings and surface seals during repairs.

DVD edition

Please note that this manual is not only available in printed form, but is also available as electronic documentation on DVD (Lidos).

Service Manual

General Information 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. The safety regulations listed below, if conscientiously followed, will ensure your own 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 are explained in this manual. These are indicated by the headings Danger, Warning or Caution.

1.1.1

Introduction 1. The symbols below have the following meanings:

Danger

Warning

Caution

Danger Warning that without appropriate precautions, certain procedures could result in fatal accidents.

Warning Warning that without appropriate precautions, certain procedures could result in severe physical injuries.

Caution Warning that without appropriate precautions, certain procedures could result in minor physical injuries or damage to the machine.

2. Observance of these instructions does not exempt you from following any additional rules and guidelines that may apply The following should also be observed: – The safety rules in force at the operating site – Legally enforceable road traffic regulations – Guidelines issued by trade associations
