Preface
Intended readership 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.
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.

Service manual Maintenance
Maintenance and inspection schedule
L586 - 461 / from 17650 3.1-1 o f 4Copyright by
MJFCIFSS!
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
– 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)
– 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.

  • 41. Service manual Maintenance Maintenance and inspection schedule L586 - 461 / from 17650 3.1-1 o f 4Copyright by MJFCIFSS! 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 – 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) – 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.
