Abstract: An orbital sander includes a housing, a motor within housing, the motor including a motor shaft defining a motor axis, an eccentric drive unit coupled to the motor shaft to convert rotation of the motor shaft to an orbit motion around the motor axis, a battery receptacle for receiving a battery pack, a backing pad coupled to the eccentric drive unit for orbital motion about the motor axis, and a dust collection assembly adjacent the backing pad for directing dust away from the backing pad. The orbital sander, including the housing, the motor, the eccentric drive unit, the battery receptacle, the backing pad, and the dust collection assembly, defines a center of gravity CGROS located on a first side of the motor axis adjacent the battery receptacle. The dust collection assembly defines a center of gravity CGDCA on a second side of the motor axis opposite the first side.

Abstract: A fastener driver includes a pusher assembly slidably coupled to a magazine assembly. The pusher assembly includes a first portion and a second portion that are selectively movable relative to each other. The pusher assembly is adjustable between a first state in which the first portion and the second portion are configured to move together in unison toward the channel, and a second state in which the first portion moves relative to the second portion toward the channel. A dry-fire lockout assembly includes a blocking member coupled to the magazine assembly or the nosepiece assembly, and a lockout member selectively engageable with the blocking member for moving the blocking member from a first position and a second position. The pusher assembly is configured to transition from the first state to the second state after a predetermined number of fasteners remain in the magazine assembly.

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.

Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center position to a bottom-dead-center position for driving a fastener into a workpiece, a drive unit for providing torque to move the driver blade toward the top-dead-center position, and a rotary lifter engageable with the driver blade. The lifter having a body and a drive pin coupled to the body. A roller is positioned on the drive pin and engages with a tooth of the driver blade when moving the driver blade from the bottom-dead-center position toward the top-dead-center position. The roller includes a first engagement section that receives an end portion of the tooth and a second engagement section. An engagement member engages the second engagement section for aligning the first engagement section of the roller with the end portion of the tooth to facilitate meshing between the end portion of the tooth and the roller.
