A fastening tool having a tool body, comprising: a housing including a cylinder; a piston slidably sealingly mounted in the cylinder for movement through an operative cycle including a drive stroke and a return stroke; a fastener driving assembly disposed within the housing, the fastener driving assembly including a fastener driving element connected to the piston for movement through a drive stroke in response to the drive stroke and return stroke of the piston; a nose portion defining a fastener drive track for movement of the fastener driving element aligned with the fastener driving assembly; a contact trip constructed and arranged to be moved from a normally biased inoperative position into an operative position when pressed against a workpiece; a first handle attached to the housing defining a tool reservoir; a trigger valve in communication with the tool reservoir and configured to initiate actuation of the fastening tool; a second handle coupled to the tool body for supplying compressed gas to the control valve; a lever valve within the second handle configured to complete actuation of the fastening tool; and characterized in that there is also provided a control valve mounted to the tool body for controlling an amount of compressed gas to the tool reservoir and further characterized in that the second handle supplies compressed gas to the control valve, the compressed gas passing through the control valve to the tool reservoir to fill a region above the piston upon actuation of the trigger valve, the lever valve, and the contact trip. a housing including a cylinder; a piston slidably sealingly mounted in the cylinder for movement through an operative cycle including a drive stroke and a return stroke; a fastener driving assembly disposed within the housing, the fastener driving assembly including a fastener driving element connected to the piston for movement through a drive stroke in response to the drive stroke and return stroke of the piston; a nose portion defining a fastener drive track for movement of the fastener driving element aligned with the fastener driving assembly; a contact trip constructed and arranged to be moved from a normally biased inoperative position into an operative position when pressed against a workpiece; a first handle attached to the housing defining a tool reservoir; a trigger valve in communication with the tool reservoir and configured to initiate actuation of the fastening tool; a second handle coupled to the tool body for supplying compressed gas to the control valve; a lever valve within the second handle configured to complete actuation of the fastening tool; and characterized in that there is also provided a control valve mounted to the tool body for controlling an amount of compressed gas to the tool reservoir and further characterized in that the second handle supplies compressed gas to the control valve, the compressed gas passing through the control valve to the tool reservoir to fill a region above the piston upon actuation of the trigger valve, the lever valve, and the contact trip. a lever valve within the second handle configured to complete actuation of the fastening tool; and characterized in that there is also provided a control valve mounted to the tool body for controlling an amount of compressed gas to the tool reservoir and further characterized in that the second handle supplies compressed gas to the control valve, the compressed gas passing through the control valve to the tool reservoir to fill a region above the piston upon actuation of the trigger valve, the lever valve, and the contact trip.
