Abstract

An electrical manual power saw includes a machine housing that has a housing shaft and a housing head (102) holding an interchangeable tool, and an electrical drive for driving the tool in an oscillating reciprocating motion. The housing shaft, for the sake of attaining an ergonomically defined gripping position in the vicinity of an on/off switch, has a rod-like shape, and in the transition region between the rod-shaped housing shaft and the housing head, a construction is provided. The on/off switch is disposed laterally offset on the housing head, below the axis of the shaft in such a way that when the constriction is grasped by a hand of a user the thumb of the grasping hand rests on its actuation knob.
