Abstract

A hand-held power tool has a main element having a tool axis, a center of gravity, and a normal axis which extends perpendicular to the tool axis and through the center of gravity. The tool axis and the normal axis define a plane of motion. A handle supported in the plane of motion such that it is movable relative to the main element. A spring unit connects the handle with the main element and includes a spring element. The handle has a handle body, a rotary element which connects the handle body and the main element. The rotary element is rotatable relative to the main element and to the handle body.
