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
circular sawing machines for firewood and dual-purpose circular sawing machines for firewood/circular saw
benches, 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 847-1:2005".
1 Scope
!This document deals with all significant hazards, hazardous situations and events as listed in Clause 4
which are relevant to firewood and dual-purpose circular sawing machines for firewood/circular saw benches,
with manual loading and/or unloading, hereinafter referred to as “machines”, designed to cut solid wood."
On Combined circular sawing machines for firewood - Log splitting machines only the circular sawing machine
for firewood is covered by this European Standard. For the requirements for the log splitting part of this
machine see EN 609-1: 1999 and EN 609-2: 1999.
!deleted text"
For Computer Numerically Controlled (CNC) machines this European Standard does not cover hazards
related to Electro-Magnetic Compatibility (EMC).
This European Standard does not apply to:
 log sawing machines where the saw unit moves to cut the workpiece;
 machines where the saw blade is capable of tilting;
 !hand-held motor-operated electric tools or any adaptation permitting their use in a different mode, i.e.
bench mounting;"
!NOTE 1 Hand-held motor-operated electric tools and saw benches to form an integrated whole with a hand-
held motor-operated electric tools are covered by EN 60745-1:2006 together with EN 60745-2-5:2007. "
 machines driven by an internal combustion engine
This European Standard is primarily directed at machines which are manufactured after the date of issue of
this European Standard.
!NOTE 2" Machines covered by this European Standard are listed under A.1.1 and/or A.1.2 of annex IV of the
Machinery Directive

circular sawing machine for firewood
a sawing machine for cross-cutting logs for firewood, with a single saw blade driven by either an electric motor
or a Power Take Off (PTO) device and which has manual loading and/or unloading. The workpiece is moved
manually to the saw blade either by:
a) a pivoting log carriage (circular sawing machine for firewood with pivoting log carriage - see Figure 1); or
b) a sliding table with a clamping device (circular sawing machine for firewood with sliding table - see Figure
2)
3.2.3
dual-purpose circular sawing machine for firewood/circular saw bench
a dual-purpose machine which is either:
a) a circular sawing machine for cross-cutting logs for firewood with a pivoting log carriage (see Figure 3b));
