0 Introduction This European Standard has been prepared to be a harmonised standard to provide one means of conforming to the essential safety requirements of the Machinery Directive, and associated EFTA regulations. This European Standard is a type “C” standard as defined in !EN ISO 12100-1:2003". The extent to which hazards are covered is indicated in the scope of this European Standard. The requirements of this European Standard concern designers, manufacturers, suppliers and importers of single blade edging circular rip sawing machines with power driven saw unit and manual loading and/or unloading. This European Standard also includes information to be provided by the manufacturer to the user. Common requirements for tooling are given in !EN 847-1:2005".
1 Scope !This document deals with all significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to single blade edging circular rip sawing machines with power driven saw unit and manual loading and/or unloading, hereinafter referred to as “machines”, designed to cut solid wood, chipboard, fibreboard and plywood." !deleted text" For Computer Numerically Controlled (CNC) machines this European Standard does not cover hazards related to Electro-Magnetic Compatibility (EMC). This European Standard applies to machines where the workpiece is stationary, the vertical and horizontal movements of the saw unit are power driven, and where the machine is provided with workpiece clamping the workpiece may or may not be clamped during cutting. This European Standard does not apply to machines:  where the workpiece is fed to the sawblade during cutting;  designed specifically for cutting veneers;  provided with a device situated behind the line of cut, which moves in a direction parallel to the line of cut, for automatically unloading the workpiece during the return of the saw unit to the rest position. This European Standard is primarily directed at machines which are manufactured after the date of issue of this European Standard. 2 Normative references !The following referenced documents are indispensable for the application of this document.
