Emergency operation of the working pump
In the event of a failure in the pump control, the performance of the hydraulic pump is automatically reduced to a minimum. For such situations, the excavator is equipped with an emergency operation function for the working pump.
It bypasses the control electronics so that the working pump can be operated at a slightly reduced output rate.
