Method for operating a handheld work apparatus having a combustion engine

A method for operating a handheld work apparatus which includes a centrifugal clutch, a work tool and a combustion engine for driving said work tool via said centrifugal clutch, said centrifugal clutch defining a coupling engaging rotational speed range (nK) wherein said centrifugal clutch engages and said coupling engaging range extending between a lower coupling engaging rotational speed (nu) and an upper coupling engaging rotational speed (no);

• said combustion engine including a fuel metering device, an ignition device, a control unit and a device for detecting the rotational speed (n) of said combustion engine, the method comprising the steps of:
• monitoring the rotational speed profile of said combustion engine in said coupling engaging rotational speed range (nK);
• and,
• increasing the power (P) delivered to drive said work tool from an operating power (P1) to an increased power (P2, P3) when said rotational speed profile corresponds to a pregiven rotational speed profile over a pregiven time span (Δt).
