charging the control volume with air pressure via a pneumatic charging connection between the control volume and the gas pressure source connection; and
after the workpiece contact element is actuated via engagement with a workpiece and after the trigger is actuated:
disconnecting the pneumatic charging connection between the control volume and the gas pressure source connection,
causing the drive-in tool to be in a trip-ready state,
discharging the air pressure in the control volume via a pneumatic discharging connection between the control volume and a pressure sink, and
after the gas pressure in the control volume falls below a gas pressure threshold, causing the drive-in tool to switch from the trip-ready state to a secured state.
