The invention relates to a compressed air-operated fastener driving tool comprising a pilot valve controlled by a manually actuated release lever, a control valve, the pressure bias of which is controlled by the pilot valve and which for its part controls the supply of compressed air to a working cylinder, and a release barrier adapted to be actuated by the workpiece by means of which the actuation of the pilot valve is adapted to be controlled in common with the release lever when placed in its working position.
