Common safety requirements for woodworking machine tools 1 Scope This document provides the safety requirements and measures for continuous woodworking machine tools (hereinafter referred to as machine tools) to reduce the risk of accidents during operation, adjustment, These safety requirements and measures are prepared by the manufacturer for most machine tools. See the commonly used conditions under the intended use within the scope, while also taking into account reasonably foreseeable misuse. This document applies to machine tools for machining solid wood and materials with similar physical properties to wood, using manual feed or mechanical feed. This document is intended to be used in conjunction with the safety requirements for specific machine tools (the safety standards for specific machine tools cover all significant hazards of that type of machine tool). The hazards covered by this document are listed in Appendix A. This document does not apply to machine tools used in potentially explosive atmospheres and to machine tools manufactured before the date of publication of this document. 2 Normative references The contents of the following documents constitute the essential clauses of this document through normative references in this document.
