This document specifies the safety requirements and measures for manually loaded and unloaded vertical panel circular sawing machines (defined in 3.1) capable of continuous production use, with hand feed or integrated feed, hereinafter referred to also as “machines”. It deals with all significant hazards, hazardous situations and events, as listed in Annex A, relevant to the machines, when operated, adjusted and maintained as intended and under the conditions foreseen by the manufacturer, including reasonably foreseeable misuse. Transport, assembly, dismantling, disabling and scrapping phases are also taken into account. It is also applicable to machines fitted with one or more of the following devices/additional working units, whose hazards have been dealt with: — an integrated feed device; — a device for scoring; — an angle cutting device; — a middle support device; — programmable end stops for parallel vertical cuts; — a device for grooving with a milling tool with a cutting width not exceeding 27 mm; — a panel pusher; — a panel lowering device; — stop devices for workpiece during horizontal cuts. The machines are designed for cutting panels consisting of: a) solid wood; b) material with similar physical characteristics to wood (see ISO 19085-1:2021, 3.2); c) composite materials with core consisting, for example, of polyurethane or mineral material laminated with light alloy; d) polymer-matrix composite materials and reinforced thermoplastic/thermoset/elastomeric materials; e) gypsum boards, gypsum bounded fibreboards; f) honeycomb aluminum boards; g) matrix engineered mineral boards, silicate boards; h) polymer-matrix composite materials and reinforced thermoplastic / thermoset / elastomeric materials; i) aluminum light alloy plates; j) composite boards made from the materials listed above. This document does not apply to machines — with pressure beam and saw unit mounted behind the workpiece support; — where the guide rails on which the saw unit moves vertically are fixed on the machine frame and the horizontal cut can only be made by manually feeding the panel; — designed to cut in vertical direction only; — automatically performing two or more cutting cycles in sequence; — intended for use in potentially explosive atmosphere; — manufactured before the date of its publication.
