The crimping tool (1) is closed hydraulically, whereby the work piece
is formed. The pressure needed for this purpose is generated by the
hydraulic hand pump (6) and transferred to the hollow piston. The sig-
nal lamp (3) lights up when the crimping diameter is reached. The
crimping tool (1) is opened by slowly opening the drainage valve
hand wheel (4).
The actual forming process is controlled via the pump handle.
