Hand-machine tool i.e. jig saw, for processing workpiece, has light controlling device provided with operation mode switching unit for changing operating mode of illuminating device based on position signal from position sensor

摘要

The hand-machine tool (10a) has a tool (15) i.e. saw blade (16), driven by a motor (11a) i.e. electronically commutated electric motor, with an operating frequency. An illuminating device (30a) has a lighting unit i.e. LED, and illuminates an operating area (31) of the tool. A position sensor (60a) outputs a position signal that represents position of the machine tool, and a filter is attached to the position sensor. A light controlling device (34a) has an operation mode switching unit (41) e.g. switch, for changing an operating mode of the illuminating device based on the signal.
