Abstract: A pneumatic fastener driver operable in a single sequential mode and a bump-fire mode, and includes a housing, a nosepiece, a trigger moveable between a default position and a depressed position, a contact arm movable relative to the nosepiece between an extended position and a retracted position, and a timeout mechanism operable in the bump-fire mode to inhibit the drive cycle from being initiated in response to inactivity of the contact arm over a preset time interval defined by unwinding of a mainspring that is initially wound in response to the trigger being actuated from the default position to the depressed position. The pneumatic fastener driver also includes a counting assembly having a female barrel pivotably coupled to a pivot shaft of the trigger and driven by the mainspring and a lockout linkage coupled to the female barrel that is capable of interfering with a portion of the trigger.

Abstract: A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly about a first axis. The saw unit includes a saw arm, a motor supported by the saw arm, and a saw blade supported by the saw arm. The saw blade is driven by the motor to rotate about a second axis. The saw blade includes a diameter. A ratio of the diameter of the saw blade to a distance between the first and second axes is between 0.4 and 0.7.

Abstract: A track saw system is configured to make a straight cut in a work piece supported upon a stand. The track saw system includes a base configured for attachment to the stand, the base having an edge against which the work piece is engageable, a track pivotably coupled to the base, a first hinge pivotably coupling the track to the base about a first pivot axis to permit pivoting movement of the track relative to the base in a direction extending away from the base, and a second hinge pivotably coupling the track to the base about a second pivot axis transverse to the first pivot axis to permit pivoting movement of the track relative to the base to adjust a miter angle between the track and the edge.
