Abstract: A gas spring-powered fastener driver includes a cylinder, a moveable piston positioned within the cylinder, and a driver blade attached to the piston and moveable therewith from a retracted position to a driven position to drive a fastener into a workpiece. A fill valve is coupled to the cylinder and operable to selectively fill the cylinder with gas to a pressure.

Abstract: A fastener driver including a cylinder, a piston positioned and moveable within the cylinder, a driver blade attached to the piston and movable with the piston, a front nosepiece at least partially defining a fastener driving track through which fasteners are driven by the driver blade, a rear nosepiece at least partially defining the fastener driving track, and a magazine attached to the rear nosepiece and operable to supply the fasteners to the fastener driving track through the rear nosepiece. The rear nosepiece and the magazine are removably coupled to the front nosepiece as a unit.

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.
