Abstract

A hand-guided motorized working apparatus and an operating device for the apparatus are provided. The operating device has a handle shank configured to be hand-gripped, an operating element receiving region adjoining the handle shank, and an operating unit which acts on the apparatus operation and includes an operating element which is held movably on the operating element receiving region for actuation by a finger of a hand gripping the handle shank, and has a finger rest region extending along an outer side of the operating element receiving region. In the operating device, the operating element is a pivot operating lever which is held on the operating element receiving region so as to be pivotable about a pivot axis, wherein the pivot axis extends with a main direction component perpendicular to a shank longitudinal axis of the handle shank, and wherein the finger rest region, in a longitudinal extension along the outer side of the operating element receiving region, has a bent and/or angled course with a circumferential direction component and an axial direction component.
