Abstract

A combustion-engined setting tool for driving fastening elements such as, e.g., nails, bolts, or pins in a workpiece, includes a plate-shaped member (17) axially displaceable in the tool combustion chamber (14), a member (33) for displacing the plate-shaped member (17), a holding device (30) for retaining the plate-shaped member (17) at an axial end (15) of the combustion chamber (14) against action of the displacing member (33), with the holding device (30) having magnetic elements (31) for producing a holding force for retaining the plate-shaped member (17) and a device for overpowering the holding force produced by the magnetic elements (31).
