A worker was ripping a wooden workpiece with a dado on a manual-feed table rip saw. When the workpiece began to bind, the worker attempted to move the workpiece through by pushing hard on it in the normal direction of operation. The workpiece subsequently broke free, exposing the circular saw blade underneath which caught the worker's fingers on his right hand. The worker suffered amputations of his index and little finger at the first knuckle, and middle and ring fingers at the second knuckle. The worker should have used a push stick to free the binding workpiece instead of his right hand.
