Abstract

A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position to a bottom-dead-center (BDC) position for driving a fastener into a workpiece and a drive unit for providing torque to move the driver blade from the BDC position toward the TDC position. A kickout arrangement is at least partially defined by an outer surface on one of a torque output member and a torque input member and an aperture formed in the other of the torque output member and the torque input member in which the outer surface is received. The kickout arrangement configured to permit limited rotation of the torque output member relative to the torque input member between a first position and a second position.
