Microprocessor electronics with soft start, restart interlock after power failure, temperature monitoring, overload protection, CDC constant electronics Reliable 1600 watt high speed motor with sufficient power reserves Dust extraction: Protects against dust pollution, lowers the disc wear, keeps the concrete pores open for the new coating Anti-kickback, switches off the motor when the disc is blocked Protective cover: with swiveling segment for grinding to the wall and height-adjustable for adjusting the height of the respective disc for optimum dust extraction With infinitely adjustable, vibration-damped, ergonomic handle for an optimum handling and machine guide For the fast hose connection: Flex clip connection for à 32 mm stop connection included in the basic equipment Recessed spindle lock against unintended actuation Variable speed for dust minimization at excess tool, as well as better control during fine work with less pressure, e.g. in the periphery and during the final smoothing of surfaces Ideal suitable for processing of wall, Ceiling and for floor working. Efficient and economical working through an optimum adjustment of machine and grinding disc for abrasive materials. For removing formwork transitions and concrete rotors on freshly concrete surfaces, mineral adhesives, screed, plaster, mortar, Abrasives lime sandstone, sandstone, shampoo, asphalt.This text is machine translated.
