US 10,252,439 B2 · Table saw and push stick for the table saw

Abstract

A push stick for a table saw and a table saw with the push stick are provided. The push stick includes a gripping possibility for a machine operator at its operator-side end. A workpiece engagement notch is formed at the push stick's workpiece-side end. The notch includes a push surface facing in an intended feed direction of the workpiece and a holding-down surface protruding therefrom at the top under a preferably right angle. The push stick includes a detection device which detects whether the push surface and the holding-down surface lie flat against the workpiece. The push stick further includes a signaling device which emits a flat contact signal when the detection device has detected a flat contact of the push surface and the holding-down surface on the workpiece. The signal therefore signals whether the push surface and the holding-down surface lie flat against the workpiece.
