Abstract: A pneumatic driver for driving a fastener including an air inlet connectable to an air supply and a pneumatically driven motor driveable by air supply about a tool axis. The driver further including a bit holder, a torque control, and a push rod in mechanical communication with the torque control such that the pin is axially positionable between an off position, a drive position and a torque blocked position. The rod moving to the drive position in response to axial pressure being applied to the bit holder and driver further including an inlet air chamber and a signal pressure chamber fluidly connecting the air inlet and the motor. The driver further including a port between the inlet and signal chambers and a second port between the pressure chamber and the motor and the rod extending through the pressure chamber into the inlet chamber and including a first seal for selectively sealing the first port and a second seal for selectively sealing the second port.
