Abstract (en)
[origin: CN104727964A] A handheld work apparatus has a combustion engine (8) which drives a tool of the work apparatus via a centrifugal clutch. The centrifugal clutch (24) couples in an engagement rotational speed range (nK) which extends between a lower engagement rotational speed (nu) and an upper engagement rotational speed (no). The combustion engine (8) has a fuel supply device, an ignition device, a control device (41) and a device for detecting the rotational speed (n) of the engine. A method for operating the handheld work apparatus makes provision for the rotational speed profile of the combustion engine to be monitored in the engagement rotational speed range (nK) and for the power (P) output for driving the tool to be increased from an operating power (P1) to an increased power (P2, P3) when the rotational speed profile corresponds with a predetermined rotational speed profile over a predetermined period of time ([Delta]t).
