Abstract

A method for operating a hand-held spray device, wherein in a first step a target orientation of the spray nozzle relative to the operator control unit is defined, and wherein during operation a rotation of the spray device, brought about by manual movement of the spray, through a z swinging angle, about a z axis which is orthogonal with respect to the longitudinal axis and/or through a y swinging angle about a y axis which is orthogonal with respect to the longitudinal axis and orthogonal with respect to the z axis, by a single sensor and wherein the z swinging angle and/or the y swinging angle engage as interference variables in a closed-loop control circuit and make available closed-loop control variables in such a way that the spray nozzle retains its target orientation by means of closed-loop control of the swinging mechanism.
