1 For information
This manual contains technical data, descriptions of design and function, repair and adjustment
instructions as well as numerous drawings, functional views and illustrations of
LIEBHERR – crawler loaders (LR) in Series 4.
This manual should simplify competent customer service of our product, however, it does not
replace expert and qualified training and attendance at our factory training classes.
Information which is in the trade considered to be basic knowledge is not included. Operation
and spare parts information can be found in separate documentation.
The manual will be updated and expanded as necessary, when changes occur in series.
During all activities on the machine, accident prevention regulations and safety guidelines must
be strictly observed.
The manual is intended for the exclusive use of the registered owners and may not be
reproduced complete or in part or passed on to a third person without our written permission
and remains property of LIEBHERR-Werk Telfs GmbH.
All rights reserved - Printed in Austria.
We reserve the right to make changes of technical details on the machine in comparison to the
information and drawings in this manual.

It is possible that there is an additional running number behind the continuous number, for
example 9.4.20 - 13/15 - 02. This number stands for updates, especially on electrical
schematics, where only one page is updated.
Changes will be issued with the same number, but with updated date. Updates will be given
new numbers. If one page applies only for a certain machine group, then this is noted in the
heading.
Note!
This sign marks special important notes in the manual.
This symbol notes a standard listing.
This symbol means:“ The prerequisite must be met“.
The maintenance personnel must first fulfill the described prerequisites, for example, to bring
the machine in working position, to be able to carry out the steps described thereafter as.
This symbol marks an activity step.
The maintenance personnel is to become active on this point and carry out the described
activity.
This symbol denotes a result.
The maintenance personnel is alerted to the fact that a result will occur after a work step, for
example, after the test button is pushed, the LED light lights up.
This note shows that the detail view of an illustration is turned by
the stated angle, as compared to the actual installation position.
(in this case 180°)
We hope that with the enclosed information we have taken yet another step to improve the
service on LIEBHERR crawler dozers, crawler loaders, pipe layers and telescopic handlers.

Safety guidelines

1.2.00 Safety guidelines
1 Introduction
Prior to and during the performance of tests, adjustments and repairs, the following
safety guidelines must be followed:
Any type of work may only be performed by qualified trained personnel or under the
supervision and responsibility of such personnel.
Qualified trained personnel are persons, who – based on specialized training and experience –
have sufficient knowledge in the general area of earthmoving machinery and the specific
technology of our machines. They must also have knowledge of all applicable laws and general
work protection regulations, guidelines and generally approved rules concerning technology and
be able to evaluate if earthmoving equipment is safe to operate and if the necessary work can be
performed without endangering themselves or third persons.
Never operate a machine with a raised cab/ operator’s platform! The machine may only be
operated with a lowered and secured cab / operator’s platform!
Always adhere to the adjustment values noted in LIEBHERR documentation when performing
adjustment work.
When delivering the machine, the operating personnel must be trained using the currently valid
operating manual. The safety guidelines in that manual must be particularly observed.
These safety guidelines must also be observed when performing testing, adjustment or repair
work. However, there are special repair and/ or inspection tasks, which require different
procedures than specified in the safety guidelines. In such cases, qualified personnel or
individuals performing the work under the supervision of such personnel should assure that
additional safety precautions necessary to insure the safety of those involved in the repair and/
or third parties are taken. The decision to carry out this measures can only be made by qualified
expert personnel. Such examples of repair and/ or maintenance include, but are not limited to
the following:
- opening of the side engine compartment doors with the Diesel engine running to carry out
tests and / or adjustments.
In these cases, it should be assured that the side doors are properly secured for the
complete duration of the work to prevent them from closing unexpectedly and / or
inadvertently. Avoid body contact with turning and / or heated parts! Wear only tight
clothing (for example no scarves, no ties, no wide sleeves, etc.)
- starting the Diesel engine with the cab tilted, as well as actuating the travel drive with
properly raised machine for adjustment, repair and diagnostics purposes. In these cases,
before starting the engine, it must be ensured that the cab support as well as the support
under the machine and the required ground clearance of the track chains has been
checked.
