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.

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.

Service manual

Maintenance Maintenance and inspection schedule

3.1 Maintenance and inspection schedule All relevant safety guidelines must be followed when carrying out all servicing, inspection or repair work. Regional work safety regulations, industrial accident prevention regulations and national legislation must be observed. You will find a list of spare parts that you need for servicing and inspection work in the "SERVICE PACK" in the spare parts list. Use only LIEBHERR original spare parts and servicing parts for all servicing, inspection and repair work. If the operating company requires the installation of other parts purchased elsewhere, a separate note must be on the inspection documents that this may result in a loss of guarantee. Do not exceed the stated maintenance and inspection intervals and if necessary these should be reduced. CAUTION Careful servicing can only be carried out if the machine is clean. Clean the machine before you start any service work. The following abbreviations are used in this section: h = service hours Various symbols (solid or empty circles, boxes and stars) are used to indicate the maintenance tasks, which fall into two main types. The symbols have the following meanings: Table with solid circle, box or star â&#x20AC;&#x201C; Responsibility for carrying out the maintenance work lies with the machine operator or his maintenance personnel. This affects the maintenance intervals every 10 and 50 service hours (h) and non-scheduled intervals. The symbols have the following meanings: Table with empty circle, box or star, or service hours (h) â&#x20AC;&#x201C; The maintenance and inspection work must be performed or supervised by authorised engineers from LIEBHERR or its authorised dealers. This affects the maintenance intervals on delivery, every 500, 1000, 2000 service hours (h), and at unscheduled times.

3.4 Filling quantities and lubrication chart 3.4.1

Filling quantities Specifications in the medium column: – The standard lubricants and fuels required for central European climate conditions are stated here. – Before you change or top up the oil in the hydraulic system (hydraulic tank), always check if it is filled with petroleum or bio oil. – For more detailed information about the required lubricants and service fuels, see the section on lubricants and fuels. Specifications in the quantity column: – The values stated for the filling quantities in the table are only guidelines. – The dipstick and level markings are always mandatory. – Each time the oil is replaced or topped up, check the level in the unit in question. Note Observe the data sheets and safety data sheets in “LH service documentation” / “General information” / “Lubricants”.
