Abstract: Power tools described herein include an electric motor, a driver blade, a trigger switch, a safety switch, and an electronic controller. The electronic controller is connected to the electric motor, the trigger switch, and the safety switch. The electronic controller is configured to initiate a retraction cycle by controlling the electric motor to move the driver blade from a first position to a second position, determine a position of the driver blade during the retraction cycle, initiate, in response to the position of the driver blade exceeding a first threshold, a braking cycle at the electric motor, and abort, in response to detecting a first activation of the trigger switch and a second activation of the safety switch, the braking cycle.

Abstract: A fastener driver includes a magazine having a latch member and a pusher slidably coupled to the magazine. The pusher includes a body and a lever movably coupled to the body. The body is configured to contact one of the fasteners for biasing the fasteners toward a nosepiece. The lever includes a first end and a second end opposite the first end. A spring is configured to bias the first end of the lever away from the body of the pusher. The first end of the lever is configured to selectively engage the latch member when the pusher is moved toward a second end of the magazine for retaining the pusher in a rearward position. The second end of the lever is movable by a user for releasing the engagement between the first end of the lever and the latch member.

Abstract: A fastener driver includes a housing, a cylinder supported by the housing, and a moveable piston positioned within the cylinder. A driver blade is attached to the piston and movable therewith between a top-dead-center position and a driven or bottom-dead-center position. The driver blade includes a body having a first side and an opposite, second side with the driving axis passing therebetween, a plurality of teeth extending from the first side of the body, and a plurality of projections extending from the second side of the body. The body and the projections are bisected by a common plane. The teeth extend at an oblique angle from the first side of the body relative to the common plane.

Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position toward a driven or bottom-dead-center (BDC) position, a gas spring mechanism for driving the driver blade toward the BDC position, a lifter assembly having a rotary lifter for returning the driver blade from the BDC position toward the TDC position, a motor that provides torque to the rotary lifter to return the driven blade from the BDC position toward the TDC position, and a cam which, during operation of the rotary lifter, causes the rotary lifter to axially move along a rotational axis defined by the rotary lifter between a first position, in which the rotary lifter is engageable with the driver blade, and a second position, in which the rotary lifter is not engageable with the driver blade.

Abstract: A powered staple driver includes a magazine configured to receive staples and a nosepiece having a staple driving channel from which consecutive staples from the magazine are driven, the staple driving channel extending along a driving axis. The magazine obliquely extends from the nosepiece in both a first plane containing the driving axis and a second plane that is perpendicular to the driving axis.

Abstract: An oscillating power tool has a housing including a handle portion defining a handle axis and a head portion defining an output axis that is perpendicular to the handle axis. The head portion includes a front face intersected by the handle axis. A drive mechanism includes an output shaft configured to oscillate about the output axis in a rotational manner in response receiving torque from a motor. A lighting assembly is configured to illuminate a workpiece in front of the head portion of the housing. The lighting assembly includes a lens arranged on the front face of the housing, a holder coupled to the lens, a plurality of printed circuit boards supported by the holder, and an LED arranged on each of the printed circuit boards. In response to being activated, the LEDs are configured to project a wide-angle beam of light through the lens.

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.
