A drive-in tool for driving fasteners into a workpiece, wherein the tool comprises in particular:



a safety device (8) which is coupled with the trigger element (6) and is set up to bring about a transfer of the drive-in tool (1) from a trip-ready state (100) into a secured state (101) after expiry (820) of a delay time which proceeds from an activation (810) of the safety device (8),
wherein the safety device (8) comprises a control volume (15),
wherein the safety device (8) comprises an activation element (33) which is changeable between a first and a second position by way of the trigger element (6),
wherein in the first position of the activation element (33) a first pneumatic connection is defined between the control volume (15) and the gas pressure source connection (23), which is hereafter referred to as charging connection (27.1),
and wherein in the second position of the activation element (33) a second pneumatic connection is defined between the control volume (15) and a pressure sink (40), which is hereafter referred to as discharging connection (33.1),
wherein one connection from the charging connection (27.1) and the discharging connection (33.1) comprises a smallest cross-sectional flow area which, together with a gas pressure of the gas pressure source, determines the delay time of the safety device (8).




The present disclosure also relates to a corresponding method for operating a drive-in tool.
