The hand grinder is used for grinding and cutting metal and concrete surfaces. The grinder should only be used with the specified grinding wheels. The diameter of the sanding surface is 125 mm. The power consumption of the grinder is 750 W and the idle speed is 11 000 min^-1. The grinder has a round handle in the front for a better grip, which makes handling the device easier and more practical. The grinder motor is sufficiently cooled and protected against overload and long use. A 230 V mains connection is required for operation. Cooling water must not be used during grinding. There is a risk of damage and danger if an unsuitable blade is used.
