Abstract
An electric motor operated hand circular saw has a base plate, a motor housing turnable relative to the base plate, an electric motor accommodated in the motor housing and having a drive shaft, a circular saw blade arranged on the drive shaft of the electric motor, and a pre-slitting abutment for adjusting a pre-slitting position of the saw blade in which the saw blade penetrates into a surface of a workpiece to be sawed by a limited pre-slitting depth. The pre-slitting abutment has two fixed abutment positions in which two different turning positions of the motor housing relative to the base plate are adjusted, so that in a first of the abutment positions during guiding the base plate over a guiding rail on a workpiece surface and in a second of the abutment positions during guiding the base plate along a strip clamped on the workpiece surface or with a parallel abutment held on the base plate on the workpiece edge on the workpiece surface, the saw blade penetrates correspondingly into the workpiece surface with a pro-slitting depth.
