Abstract
A hand-portable garden, forestry and/or construction processing device has a cutting tool, an electric drive motor, a motor operating element, and a control device. The cutting tool is designed for cutting through work. The drive motor is designed for driving the cutting tool. The motor operating element is user-adjustable over an adjustment range from a minimum setting to a maximum setting. The control device is designed for controlling a target speed of the drive motor in accordance with a setting of the motor operating element in at least one first operating mode and one second operating mode. In the first operating mode, the target speed increases over at least one segment from a minimum of 0.5 times the adjustment range as the setting increases, wherein the increase changes over the segment by a maximum of 60%. In the second operating mode, the target speed is a minimum of 0.9 times a maximum target speed of the second operating mode as the setting increases from a maximum of 50% of the adjustment range.
