Using a model other than the compatible model or using it for purposes other than the intended use is dangerous and may lead to accidents. Do not use for purposes other than the intended use. ●Check the maximum allowable rotation speed (circumferential speed) printed on the package, label, catalog, and other related documents, and use within the allowable range. Never use it beyond this range. ●When operating the power brush, be sure to wear a brush protective cover, gloves, a safety helmet, dust-proof tight-fitting protective glasses, and a mask for safe operation. ●When using a power brush, burrs, scale, dirt, slag, etc. are generally scattered with considerable force along with the filament (wire fragments), so keep away anything that is easily flammable, explosive, or damaged. Also, work in clothes that cover your skin so that the grinding powder does not directly hit your hands or feet. ●If the wire brush filament (wire fragments) or grinding powder scatters, it is dangerous, so people around the work area (within 15m of the brush) should also wear protective glasses and protective clothing during work. (As a consideration for people in the vicinity other than the worker, please install curtains, etc., or clear people or give instructions to block the area.)
