This manual contains technical data, design and functional descriptions as well as instructions for the operation and the adjustment of machine settings. The document includes a number of drawings, functional schematics and detailed views of units and assemblies of Liebherr hydraulic excavators.

The documentation has been designed to support customer support services, but does of course not replace proper technical training and qualification of the user, and participation in Liebherr operator training courses.
General basic technical information is not included in this manual. For operating instructions and information on spare parts, please refer to the separate documentation.

Clamping nuts are used to secure pins with pin tabs and anti-torsion elements.
Pins secured in this way prevent bending of the bearing covers (e.g. bearing covers at the swivelling arm, the boom and the stick), improve the stability of the machine and can withstand higher loads.
If clamping nuts are tightened too much, the following might result:
– Bearing covers might become bent backwards
– Welded seams might break
– Excessive friction between the connected steel components
– Increased wear
– Damage to bearing
