Abstract:
Herein a hand-held power tool comprising an internal combustion engine ( 4 ) is disclosed. The hand-held power tool comprises, a working tool ( 6 ), a centrifugal clutch ( 8 ), and a control system ( 10 ). The internal combustion engine ( 4 ) has a clutch-in speed (ωC) above which the internal combustion engine ( 4 ) drives the working tool ( 6 ). A speed limitation controller ( 14 ), is configured to limit an engine speed at a limitation speed below the clutch-in speed (ωC). The control system ( 10 ) is configured to calculate an integral of the rotational speed of the internal combustion engine ( 4 ), and to deactivate the speed limitation controller ( 14 ) after the integral reaches an integration limit value, such that the internal combustion engine ( 4 ) is rotatable above the limitation speed (ωL) to drive the working tool ( 6 ) via the centrifugal clutch ( 8 ).

Claim (Index 1):
A hand-held power tool comprising an internal combustion engine, a working tool, a centrifugal clutch, and a control system, wherein the working tool is driven by the internal combustion engine via the centrifugal clutch, wherein the internal combustion engine has a clutch-in speed above which the internal combustion engine drives the working tool, wherein the internal combustion engine is controlled by the control system, the control system comprising a rotation speed sensor, and a speed limitation controller, wherein the speed limitation controller is configured to limit an engine speed at a limitation speed, the limitation speed being below the clutch-in speed, and wherein the speed limitation controller is active or activated during a starting procedure of the internal combustion engine,\n characterised in that the control system is configured to calculate an integral of the rotational speed of the internal combustion engine, and to deactivate the speed limitation controller after the integral reaches an integration limit value, such that the internal combustion engine is rotatable above the limitation speed to drive the working tool via the centrifugal clutch.
