In this part we describe all functions; testing and adjustment procedures.
Of course for better understanding of the systems the hydraulic and electric circuit
diagram is very helpful and a must for fault finding. - Whenever it is possible for the description the circuit diagram numbers/ codes
are used. One who is not able to understand the circuit diagram or is not so familiar with
the used symbols should study the hints for the circuit diagrams Section 10
and 11.
