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 machinery concerned and the extent to which hazards, hazardous situations and events covered are
indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this C type standard take precedence over the provisions of other standards, for machines that
have been designed and built according to the provisions of this type C standard.
The requirements of this European Standard are directed to manufacturers and their authorised
representatives of semi-automatic and automatic horizontal cutting cross-cut sawing machines with one saw
unit (radial arm saws). It is also useful for designers.
This European Standard also includes examples of information which can 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 semi-automatic and automatic horizontal cutting cross-cut sawing machines with one
saw unit (radial arm saws), hereinafter referred to as "machines", designed to cut solid wood, chipboard,
fibreboard, plywood and also these materials when covered with plastic edging and/or plastic/light alloy
laminates. "
Any work-piece positioning equipment fitted to the machine is included in this European Standard.

This European Standard does not apply to machines:
a) with manual feed of the saw unit; or
b) for cross cutting logs; or
c) specifically designed for sawing and/or milling roof timber frames; or
d) fitted with hydraulic braking systems.
˜NOTE 1™ Radial arm saws with manual feed of the saw unit (the saw unit is moved by hand) are dealt with in
prEN 1870-17 and prEN 61029-2-2.
For Computer Numerically Controlled (CNC) machines this European Standard does not cover hazards
related to Electro-Magnetic Compatibility (EMC).
˜NOTE 2™ The requirements of this European Standard apply to all machines whatever their method of control
e.g. electromechanical and/or electronic.
This European Standard is primarily directed to machines which are manufactured after the date of issue of
publication by CEN.
