High loads on the stick can cause the stick ram to be “emptied” on the base side, which

base side.
The regeneration valve is located in the stick segment on the lower side.
A nozzle is integrated in the pressure line of the bucket segment. If the bucket and the

simultaneously, and not the bucket (with its smaller mass) first, and then the boom with its
larger mass
