    Abstract: A fastener driver includes a housing defining a head portion and a handle portion, a drive mechanism positioned within the housing, and a firing mechanism. The firing mechanism includes a piston, a driver blade attached to the piston, a biasing member having a first end supported within the piston and a second end supported by the head portion, and a damper positioned between the firing mechanism and the head portion of the housing. The damper configured to attenuate one or more of noise or vibration from the firing mechanism as the driver blade moves from the top dead center position toward the bottom dead center position.

    Abstract: A fastener driver includes a magazine having a magazine cover and a magazine body. The magazine cover includes a top surface having an opening defined therein. The magazine body is slidably movable relative to the magazine cover from a closed position to an open position. A latch is coupled to the top surface of the magazine cover and extends through the opening in the top surface of the magazine cover. The latch includes a latch projection that defines a first contact surface. A pusher body is slidably coupled to the magazine body and includes an arm member that defines a second contact surface. A biasing member biases the pusher toward a nosepiece when the magazine body is in the closed position. The first and second contact surfaces are engageable to hold the pusher body in a latched position when the magazine body is in the open position.

    Abstract: A powered fastener driver includes a housing, a cylinder within the housing, the cylinder containing a pressurized gas, a piston within the cylinder and movable from a top-dead-center position to a bottom-dead-center position, a driver blade movably coupled to the piston, a lifter, a drive unit configured to provide torque to the lifter, and a sensor. The driver blade has a plurality of teeth defining a predetermined number of edges. The sensor is configured to detect an edge of one or more of the plurality of teeth and a controller in communication with the drive unit and the sensor. The controller is configured to count a number of edges detected by the sensor, compare the number of detected edges to the predetermined number of edges, and stop the drive unit when the number of detected edges is less than the predetermined number of edges.
