A fastener driving tool trigger assembly comprising: a rotary damper coupled to a tool housing, the rotary damper having a damper shaft; a driven gear coupled to the damper shaft to transfer rotation of the driven gear to the damper shaft in a first direction; a drive gear coupled to the tool housing and being movable between a timed-out position and a wind-up position and biased toward the timed-out position; the drive gear being operably coupled to the driven gear to rotate the driven gear in the first direction as the drive gear moves away from the wind-up position toward the timed-out position and to rotate the driven gear in a second direction opposite the first direction as the drive gear moves away from the timed-out position toward the wind-up position; a trigger pivotably coupled to the tool housing and movable between a trigger home position and a trigger firing position; an actuator pivotably coupled to the trigger and movable between an actuator home position and an actuator firing position; a wind-up arm coupled to the trigger and engageable with the drive gear to move the drive gear from the timed-out position to the wind-up position in response to the trigger moving from the trigger home position to the trigger firing position; a contact trip coupled to the housing and movable between a trip home position and a trip firing position and, with the drive gear positioned between the timed-out and wind-up positions, the contact trip being engageable with the drive gear to move the drive gear into the wind-up position as the contact trip moves from the trip home position to the trip firing position and, with the trigger positioned in the trigger firing position, the contact trip being engageable with the actuator to move the actuator into the actuator firing position as the contact trip moves from the trip home position to the trip firing position and, with the drive gear positioned in the timed-out position, the contact trip being engageable with the drive gear, with the drive gear in an orientation which prevents the contact trip from rotating the drive gear into the wind-up position and prevents the contact trip from moving into the trip firing position. a rotary damper coupled to a tool housing, the rotary damper having a damper shaft; a driven gear coupled to the damper shaft to transfer rotation of the driven gear to the damper shaft in a first direction; a drive gear coupled to the tool housing and being movable between a timed-out position and a wind-up position and biased toward the timed-out position; the drive gear being operably coupled to the driven gear to rotate the driven gear in the first direction as the drive gear moves away from the wind-up position toward the timed-out position and to rotate the driven gear in a second direction opposite the first direction as the drive gear moves away from the timed-out position toward the wind-up position; a trigger pivotably coupled to the tool housing and movable between a trigger home position and a trigger firing position; an actuator pivotably coupled to the trigger and movable between an actuator home position and an actuator firing position; a wind-up arm coupled to the trigger and engageable with the drive gear to move the drive gear from the timed-out position to the wind-up position in response to the trigger moving from the trigger home position to the trigger firing position; a contact trip coupled to the housing and movable between a trip home position and a trip firing position and, with the drive gear positioned between the timed-out and wind-up positions, the contact trip being engageable with the drive gear to move the drive gear into the wind-up position as the contact trip moves from the trip home position to the trip firing position and, with the trigger positioned in the trigger firing position, the contact trip being engageable with the actuator to move the actuator into the actuator firing position as the contact trip moves from the trip home position to the trip firing position and, with the drive gear positioned in the timed-out position, the contact trip being engageable with the drive gear, with the drive gear in an orientation which prevents the contact trip from rotating the drive gear into the wind-up position and prevents the contact trip from moving into the trip firing position.
