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 repair 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.

Checking of the Diesel engine output (Powertest)
Principle
The measured power is the hydraulic power at the output of the pumps. For this measure, the pump are blocked at maximum swivel angle and output pressure is slowly increased to lower the engine speed until it reaches its nominal rpm.
The engine power is correct if, at this moment, the output pressure is equal to the value Powertest prescribed in the adjustment check list.
