ABSTRACT:
A portable setting device for driving fastening elements (4) through a structural member (B) has a muzzle part (1) mounted on and extending outwardly from a housing (2). The muzzle part (1) has a receiving region (5a) in a barrel (5) for a fastening element (4) in position ready to be driven. A feeler (47) is positioned on and extends in the driving direction outwardly from a leading end of the muzzle part (1). When the leading end of the feeler (47) is displaced rearwardly flush with the leading end of the muzzle part (1) the fastening element driving operation can be carried out. A pivotally mounted locking lever (50) is arranged to block the rearward displacement of the feeler (47) when there is not a fastening element (4) in the receiving region (5a). Accordingly, the setting device can not be operated unless a fastening element (4) is present in the receiving region (5a).
