The clutch is configured to generate a drive connection with the crankshaft. A spark plug arranged in a combustion chamber. A rpm lock circuit is switched off (40) when the control variable for adapting the operating parameters is laid outside a predetermined bandwidth of the absolute magnitude of the control variable.
