Abstract
The invention relates to a pneumatic nailer having a working piston and a common actuation that is configured to trigger a drive-in process which has a control volume and which is designed to automatically undertake a safety measure when a pressure threshold in the control volume is exceeded or not met. The control volume is ventilated or vented via a throttle such that a delay time, after the expiration of which the pressure threshold is exceeded or not met, is specified by a volume of the control volume and an opening cross-section of the throttle. The control volume has a volume in the range from 0.5 ml to 20 ml and the throttle is a bore having a diameter in the range from 30 μm to 200 μm.
