Electronics: Continuous speed selection, constant speed maintenance, overload protection and temperature monitoring Brushless motor with a high degree of efficiency and longer life Completely cast electronics component prevents damage through dust. The 3-fold winding protection reduces the wear of the engine and extends the life of the grip cover for a pleasant handling and precise control Equipped with innovative changing head system Sanding heads can be attached with one click and remove segment grinding head with rotating edge segment. This enables the processing of surface transitions wall/wall and wall/ceiling. The rotation takes place without interruption of work by the movement of the machine The effective extraction between the brush ring and the grinding disc prevents a drop of the grinding agent and provides for dust-free working Defined hose guide and effective dust extraction through a large suction section. The suction hose is connected directly to the machine with the Flex clip system Light and handy for use on smaller surfaces, narrow spots Ideal suitable for grinding plasterboard, full thermal polystyrene panels as well as for painting preparationThis text is machine translated.
