Foreword
This Service manual is intended for trained specialist staff in the Liebherr organization and its dealers.
The Service manual provides specific knowledge for the maintenance of Liebherr construction machinery. Basic technical knowledge of electrics, hydraulics, mechanics and Diesel engine technology are not detailed in this Service manual. A
subject-based, qualified training is therefore necessary. Liebherr recommends participation on the Liebherr Training program for construction machinery.
In this Service manual you find information about:
— Special tools
— Technical data
— Maintenance intervals and maintenance tasks
— Adjustment procedure
— Design and functional descriptions
— Removal and installation tasks
— Wiring diagrams, hydraulic schematics and technical drawings
For information relating to control and operation refer to the operator’s manual. For information relating to spare parts refer to the Spare parts catalog. Observe the locally applicable accident prevention regulations.
