Foreword
This European Standard has been prepared by Technical Committee CEN/TC 142 "Woodworking machines
- Safety", the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by September 2001, and conflicting national standards shall be
withdrawn at the latest by September 2001.
This European Standard has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this standard.
Organisations contributing to the preparation of this European Standard include European Committee of
Woodworking Machinery Manufacturers Association "EUMABOIS".
Annex A is normative, the annexes B and ZA are informative.
The European Standards produced by CEN/TC142 are particular to woodworking machines and complement
the relevant A and B Standards on the subject of general safety (see introduction of EN 292-1 : 1991 for a
description of A, B and C standards).
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark,
Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal,
Spain, Sweden, Switzerland and the United Kingdom.
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 292-1 : 1991.
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
multiblade rip sawing machines with 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 : 1997.
1Scope
This European Standard sets out the requirements and/or measures to remove the hazards and limit the risk
on multiblade rip sawing machines with manual loading and/or unloading as defined in 3.1, herein after
referred to as „machines“, designed to cut solid wood, chipboard, fibreboard, plywood and also these
materials where they are covered with plastic edging and/or plastic/light alloy laminates.
This European Standard covers the hazards relevant to this machine as stated in clause 4.
This European Standard does not apply to machines with vertical roller feed or vertical chain conveyor feed
or machines designed to make the first rip cut on a log.

3 Terms and definitions
For the purposes of this European Standard the following terms and definitions apply :
3.1 multiblade rip sawing machine
a machine designed to be used with sawblades at different positions on the spindle(s) which are fixed in
position during cutting, where the workpiece is fed to the blades by an integrated power feed e.g. rollers,
chain conveyor or chain bed, and which has manual loading and/or unloading. The sawblades can be
mounted on one or more saw spindle(s) which may be capable of vertical adjustment. The sawblades may be
capable of axial adjustment. The sawblade spindle(s) may be arranged so that they are :
a) all mounted above the workpiece support;
b) all mounted below the workpiece support;
c) mounted both above and below the workpiece support.
The cutting mode can be ‘against the feed’ (see figure 1a).or ‘climb cutting’ (see figure 1b) or a combination
of both.
