ABSTRACT:
A portable electric fastener driving apparatus includes a unique fastener driving element operatively connected to the piston of an air spring which is charged to provide energy for driving fasteners. The air spring is charged by a unique jacking and release system including a drive gear selectively engaging a rack on the driving element to move the piston and compress the air spring. Motive power for the jacking apparatus is provided by a motor, preferably remote from the driver apparatus and connected thereto by a flexible drive cable. Control apparatus is included.
