Abstract
A fastener driving device includes a fastener driver, a magazine for carrying a supply of fasteners to the fastener driver, a spring that moves the fastener driver through a drive stroke, and a motor configured to move the fastener driver through a return stroke. The motor is operable upon completion of the drive stroke, to move the fastener driver partially through the return stroke a predetermined amount to partially pre-compress the spring. The motor is further operable to fully compress the spring after receiving a signal for the drive stroke.
