Yutani grinders are ideal for grind finishing, removing paint from exterior plates, finishing process of die-casts in maritime vessels, vehicles and automobiles, besides general grinding operations. These compact, lightweight Yutani pneumatic grinders offer trouble- free performance. Because of simple construction and long endurance with continuous use without breakdown, Yutani air grinders are used for various purposes, and accordingly there are various types and styles suited for different uses. Yutani grinders, depending on the speed (RPM) of them, are roughly categorized into low speed (vitrified) and high speed (resinoid). The rotation speed is scientifically controlled by the use of an air regulator, with little consumption of air. During the grinding operation, the speed is not reduced by the regulator so that the power remains strong enough to maintain high efficiency with suitable grinding rotation. Exhaust noise is minimal due to special construction design employed. When starting up a grinder, be sure to keep speed at a low level and gradually increase to high speed to avoid accidents. In addition, make sure the grinding wheel cover is securely mounted during operation.
