Abstract: A powered fastener driver includes a driver blade and a drive unit having an output shaft for providing torque to move the driver blade from the bottom-dead-center position toward the top-dead-center position. A rotary lifter is engageable with the driver blade and configured to receive torque from the output shaft of the drive unit in a first rotational direction for returning the driver blade from the bottom-dead-center position toward the top-dead-center position. A kickout arrangement is defined between the lifter and the output shaft and configured to permit limited movement of the lifter relative to the output shaft between a first position and a second position. The kickout arrangement having a curvilinear slot defined in the rotary lifter in which a portion of the output shaft is received. Movement of the rotary lifter from the first position toward the second position causes the slot to move relative to the output shaft, while the output shaft remains within the slot.
