This European Standard applies to hand-held non-electric power tools driven by rotary or linear motors, powered by compressed air or hydraulic fluid and intended to be used by one operator and supported by: -- the operator's hand or hands; -- a harness; -- a suspension, e.g. a balancer. This European Standard applies to hand-held non-electric power tools intended for grinding and cutting-off, with bonded, coated and super abrasive products for use on all kinds of materials. This European Standard lists the significant hazards caused by such power tools and specifies safety requirements valid for different aspects of safety during their foreseeable lifetime. This part of the standard covers power tools used with: -- abrasive products with a peripheral operating speed less than or equal to 80 m/s; -- cutting-off wheels with a peripheral operating speed less than or equal to100 m/s; -- abrasive products with outside nominal diameter less than or equal to 230 mm; -- cutting-off wheels with outside nominal diameter less than or equal to 300 mm; -- wire brushes.
