A pneumatic fastener driving device includes a housing assembly defining a drive chamber therein and a handle portion defining a reservoir for containing a source of air under pressure at a predetermined pressure value, the housing assembly defining a drive track; a drive piston and fastener driving element assembly sealingly mounted in the cylindrical drive chamber for movement through a drive stroke and a return stroke, a magazine assembly for receiving a supply of fasteners and feeding successive fasteners into the drive track; a power control assembly for effecting the fastener drive stroke of the fastener driving element, a piston pressure chamber communicating with an end of the drive chamber, surfaces defining a passageway within the housing assembly for communicating the pressure reservoir with the piston pressure chamber, an energy control assembly constructed and arranged with respect to the passageway and the housing assembly to be manually movable between (1) a first position wherein the passageway is opened fully to communicate the pressure reservoir with the piston pressure chamber thereby permitting the air under pressure to communicate with the piston pressure chamber to provide maximum energy to the piston and (2) a second position wherein the passageway is at least partially closed restricting a flow of the air under pressure from the pressure reservoir to the piston pressure chamber thereby reducing energy to the piston while the air under pressure is maintained at the predetermined pressure value.
