Abstract
A method of operating a fastener driver comprises initiating a fastener driving operation by moving a driver blade from a retracted position toward a driven position, and detecting that the driver blade has become jammed in an intermediate position between the retracted position and the driven position. The method further includes moving a latch from a locked position, in which a lifter assembly is maintained in an engaged position by the latch for moving the driver blade from the driven position toward the retracted position, to a released position, in which the lifter assembly is movable away from the driver blade. The method further includes driving a motor to rotate a lifter of the lifting assembly, thereby moving the lifter assembly away from the driver blade, then, returning the lifter assembly to the engaged position, and moving the latch from the released position to the locked position.
