A portable tool having an upright starting orientation in which the portable tool has a top and bottom, a front and rear, and laterally spaced sides. The portable tool has an elongate frame and is configured to be held with the user engaging: a) a first back region of the portable tool with one of the user's hands; and b) a second region of the portable tool forward of the first back region with the user's other hand to thereby allow the user to elevate and reposition the portable tool. A drive operates a working unit on the frame. The first back region and second region are spaced along a front-to-rear first line. A gripping assembly at the second region of the portable tool has an elongate gripping length extending in a second line. A first vertical plane parallel to the first line is non-orthogonal to a second vertical plane parallel to the second line. The elongate gripping length can be moved selectively forwardly and rearwardly relative to the frame.

A method operates a hand-guided processing device having a user-activated operating sensor device with a plurality of different detection positions. The method involves the steps: a) detecting a sequence of activations of the operating sensor device at different detection positions of the plurality of detection positions, and b) when the detected sequence corresponds to a given sequence, calibrating the operating sensor device for at least one detection position of the plurality of detection positions based on at least one of the activations of the detected activations.
