Abstract
A cycle of operation of an attaching apparatus begins with determining whether an operator's extremity is in an area in which it can be struck by a downwardly moving ram during attachment of two fasteners to each other and to a material therebetween. If it is determined that the operator's extremity is not in the area in which it can be struck by the downwardly moving ram, the remainder of the cycle of operation is completed. If it is determined that the operator's extremity is in the area in which it can be struck by the downwardly moving ram, the cycle of operation must begin again.
