ABSTRACT OF THE DISCLOSURE A manual tool is driven by an electric motor, and has a primary handle and a secondary handle arranged at a distance from each other. A switch is situated in the manual tool and can only be switched on by the simultaneous actuation of two contact mechanisms, one arranged in each handle, the motor being switched off when grip on either handle is released. The tool further comprises an initiating device in the form of a safety interlock mechanism which is adapted to prevent actuation of the switch, unless the safety interlock mechanism is actuated prior to actuation of the contact mechanism arranged in the primary handle. The switching mechanism is particularly suitable for a hedge clipper or chainsaw, especially a cordless tool.
