Abstract
A method of operating a hydraulically or electric motor operated tool includes providing a device shaft having electrical contacts; providing an accumulator having an adapter comprising a wall thereon; latching the adapter to the device shaft by a latching part; and engaging a tool with the latching part thereby detaching the adapter from the device shaft, whereupon during engagement of the tool with the latching part, the wall of the adapter is destroyed. When the device shaft and adapter are engaged, walls of the device shaft and adapter form an internal cavity and the latching part is positioned entirely therewithin such that the latching part is completely hidden from view. A hydraulically or electric motor operated tool is also disclosed.
