This manual has been prepared to provide you with technical information on the design and construction of the various components which made up the LIEBHERR excavator.

It contains brief and precise descriptions, guidelines and drawings of adjustment procedures as well as hydraulic and electrical schematics, and graphically depicted diagrams and sectionals to help you with any repairs, which might become necessary on our hydraulic excavators.

We deliberately avoided full drawings and details of each repair stage, a practice often adopted in workshop manuals of this kind, since only skilled mechanics already familiar with most re-pair work described in this manual, should perform repair work. This manual is also intended to provide you with information regarding certain adjustment values.
Instructions on maintenance is excluded from this manual, since it are covered in the individual Operation and Maintenance Manual.

Be sure to observe all accident prevention guidelines and adhere to all safety information before and during any maintenance and I or repair procedure on the hydraulic excavator.
To perform tests and repairs listed in this manual, a complete set of standard tools, as well as special tools and fixtures shown and listed, is necessary. Always observe utmost cleanliness and order.

No special emphasis is put on replacing sealing components, since it is taken for granted that all removed seals, 0-rings and gaskets are replaced during the course of repair. Tighten any screw connections, if no other values are given, to the required tightening torque.
Certain notes are used throughout this manual to emphasize important or critical instructions.
