Abstract
A hand-held drive-in tool () has a trigger switch () for triggering a drive-in process by drive unit () that drives a drive-in ram (), a press-on feeler () which is arranged so as to be displaceable at a muzzle (), which can detect that the drive-in tool pressed against a workpiece, and which prevents the actuation of a drive-in process in its initial position () and enables actuation of its drive-in process in its switching position (), a component feeler () displaceably arranged at the muzzle () and capable of being actuated independently from the press-on feeler () and preventing actuation of a drive-in process in its initial position () and enabling the actuation of the drive-in process in its switching position (), the component feeler () detecting fitting of an auxiliary constructional component () to the muzzle (), with a drive-in process being initiated by the trigger switch () only when the component feeler () and the press-on feeler () are both in their respective switching positions ().
