Foreword
This document (prEN 1807-2:2009) has been prepared by Technical Committee CEN/TC 142 “Woodworking
machines - Safety”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1807:1999.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of the Machinery Directive.
For relationship with EU Directive, see informative Annexes ZA and ZB, which are integral parts of this
document.
Organisations contributing to the preparation of this European Standard include European Committee of
Woodworking Machinery Manufacturers Association "EUMABOIS".
The European Standards produced by CEN/TC 142 are particular to woodworking machines and complement
the relevant A and B Standards on the subject of general safety (see introduction of EN ISO 12100-1:2003 for
a description of A, B and C standards).

Introduction
This document has been prepared to be a harmonized standard to provide one means of conforming to the
essential safety requirements of the Machinery Directive and associated EFTA regulations. This document 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 are 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 type C 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 document are directed to manufacturers and their authorized representatives of log
band saws, with and without travelling table, reciprocating carriage, moving head rig or conveyor feed. They
are also useful for designers.
This document also includes provisions and examples of information to be provided by the manufacturer to
the user.
1 Scope
This document deals with the significant hazards, hazardous situations and events as listed in Clause 4 which
are relevant to stationary and displaceable log band sawing machines with either manual or automatic loading
and/or unloading, hereinafter referred to as “machines”, designed to cut solid wood, when they are used as
intended and under the conditions foreseen by the manufacturer.
This document does not apply to:
a) table band saws and band re-saws
NOTE 1 table band saws and band re-saws are covered by prEN 1807-1:2008.
b) specific hazards related to automatic loading and/or unloading.
c) any hazards relating to the combination of a single machine being used with any other machine (as part
of a line – e.g. loading and/or unloading automated systems).
d) any hazards arising from any other machining processes (e.g. milling and sawing) related to associated
machines or cutting groups, e.g. canters and circular saws.
This document is not applicable to log band sawing machines which are manufactured before the date of its
publication as EN.
NOTE 2 - Machines with manual loading and/or unloading covered by this document are listed under A.4 of Annex IV of
the Machinery Directive.
