Safety of woodworking machines - One side moulding machines with rotating tool - Part 2: Single spindle hand fed/integrated fed routing machines

This document specifies all significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to stationary and displaceable single spindle hand fed/integrated fed routing machines with fixed head but allowing only movement along the axis of the tool during machining hereinafter referred to as "machines" designed to cut solid wood, chip board, fibreboard, plywood and also these materials if they are covered with plastic laminate, edgings or veneer when they are used as intended and under the conditions foreseen by the manufacturer. This document does not apply to inverted pin routers and radial arm routers (machines where the work piece is fixed and the tool head is manually moved); NC boring machines and NC routing machines; hand-held routers or any adaptation permitting their use in a different mode, e.g. bench mounting; routing machines set up on a bench or a table similar to a bench, which are intended to carry out work in a stationary position, capable of being lifted by one person by hand. The bench can also be an integrated part of the machine if it consists of hinged legs which can be extended down. This document is not applicable to single spindle hand fed/integrated fed routing machines which are manufactured before the date of its publication as EN.
