Abstract

The invention relates to a method for operating a hand-held working device ( 1 ), which comprises a data acquisition unit ( 24 ) in which actuations of the trigger switch and accelerations of the working device ( 1 ) are captured. In order to further simplify and/or improve the operation of the hand-held working device, it is monitored within a limited period of time after actuation of the trigger switch whether an acceleration of the working device ( 1 ) exceeds an acceleration threshold in order to detect trouble-free ignitions and/or ignition problems during the operation of the working device ( 1 ).

First claim

The invention claimed is:

1. A method for operating a fastener-setting working device comprising a trigger switch and a data-acquisition unit which detects trigger switch actuations and accelerations of the working device, the method comprising monitoring and determining, within a limited period of time after actuation of the trigger switch, whether an acceleration of the working device exceeds an acceleration threshold, and, based upon a determination of whether the acceleration of the working device exceeds the acceleration threshold, detecting fault-free ignitions/settings and/or ignition/setting faults during operation of the working device.

2. The method according to claim 1 , comprising determining a fault-free ignition/setting if the acceleration exceeds the acceleration threshold.

3. The method according to claim 2 , comprising determining an ignition fault/setting fault if the acceleration of the working device fails to reach the acceleration threshold.

4. The method according to claim 2 , comprising detecting progression of the acceleration within the limited period of time.

5. The method according to claim 2 , wherein a number of fault-free ignitions/settings and/or a number of ignition faults/setting faults are detected, and the number of fault-free ignitions/settings and/or the number of ignition faults/setting faults is stored.

6. The method according to claim 1 , comprising determining an ignition fault/setting fault if the acceleration fails to reach the acceleration threshold.

7. The method according to claim 6 , comprising detecting progression of the acceleration within the limited period of time.

8. The method according to claim 6 , wherein a number of fault-free ignitions/settings and/or a number of ignition faults/setting faults are detected, and the number of fault-free ignitions/settings and/or the number of ignition faults/setting faults is stored.

9. The method according to claim 1 , comprising detecting progression of the acceleration within the limited period of time.

10. The method according to claim 9 , comprising determining a fault-free ignition/setting if the acceleration within the limited period of time has a progression defined for a fault-free operation.

11. The method according to claim 10 , comprising determining an ignition fault/setting fault if the acceleration within the limited period of time does not have a progression defined for a fault-free operation.

12. The method according to claim 10 , wherein a number of fault-free ignitions/settings and/or a number of ignition faults/setting faults are detected, and the number of fault-free ignitions/settings and/or the number of ignition faults/setting faults is stored.

13. The method according to claim 11 , wherein a number of fault-free ignitions/settings and/or a number of ignition faults/setting faults are detected, and the number of fault-free ignitions/settings and/or the number of ignition faults/setting faults is stored.

14. The method according to claim 9 , comprising determining an ignition fault/setting fault if the acceleration within the limited period of time does not have a progression defined for a fault-free operation.

15. The method according to claim 14 , wherein a number of fault-free ignitions/settings and/or a number of ignition faults/setting faults are detected, and the number of fault-free ignitions/settings and/or the number of ignition faults/setting faults is stored.

16. The method according to claim 9 , wherein a number of fault-free ignitions/settings and/or a number of ignition faults/setting faults are detected, and the number of fault-free ignitions/settings and/or the number of ignition faults/setting faults is stored.

17. The method according to claim 1 , wherein a number of fault-free ignitions/settings and/or a number of ignition faults/setting faults are detected, and the number of fault-free ignitions/settings and/or the number of ignition faults/setting faults is stored.

18. The method according to claim 1 , wherein a number of fault-free ignitions/settings and/or a number of ignition faults/setting faults are detected, and the number of fault-free ignitions/settings and/or the number of ignition faults/setting faults is displayed on the working device.

19. The method according to claim 1 , wherein a number of fault-free ignitions/settings and/or a number of ignition faults/setting faults are detected, and the number of fault-free ignitions/settings and or the number of ignition faults/setting faults is displayed and/or read out.

20. The method according to claim 1 , wherein a number of fault-free ignitions/settings and/or a number of ignition faults/setting faults are detected, and the number of fault-free ignitions/settings and/or the number of ignition faults/setting faults is output via remote data transmission.
