Introduction
This document 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 document is a type C standard as defined in #EN ISO 12100:2010$.
The machinery concerned and the extent to which hazards, hazardous situations and events covered are
indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of other standards, for machines that
have been designed and built according to the provisions of this type C standard.
The requirements of this document are directed to manufacturers and their authorised representatives of
vertical panel sawing machines. This document is also useful for designers and importers.
This document also includes provision and examples of information to be provided by the manufacturer to the
user.
Common requirements for tooling are given in #EN 847-1:2005+A1:2007$.
1 Scope
This document !specifies all" significant hazards, hazardous situations and events as listed in Clause 4
which are relevant to manually loaded and unloaded vertical panel sawing (with or without integrated feed)
machines fitted with:
 the facility for scoring;
 an angle cutting device;
 a middle support device;
 a programmable stop for parallel vertical cuts;
 the facility for grooving with a width of at most 20 mm in one pass by using a milling tools,
hereinafter referred to as "machines" when they are used as intended and under the conditions foreseen by
the manufacturer #including reasonably foreseeable misuse$.
The machines are designed for cutting panels of the following materials:
a) wood based materials such as chipboard, fibreboard, plywood and also these materials where they are
covered with plastic / light alloy laminates;
b) solid wood;
c) hardened rubber and hardened plastic material;
d) non ferrous materials e.g. light alloy;
e) compound materials with core consisting of polyurethane or mineral material laminated with light alloy.
This document does not apply to vertical panel saws with pressure beam and saw unit mounted behind the
workpiece support.
This document does not deal with hazards relating to the combination of a single machine being used with any
other machine (as part of a line).
This document is not applicable to vertical panel saws which are manufactured before the date of its
publication as EN.
NOTE Machines covered by this standard are listed under #1.4$ of Annex IV of the Machinery Directive.

5 Safety requirements and / or measures
5.1 General
The machine shall comply with the safety requirements and / or protective measures of Clause 5.
NOTE 1 In addition, the machine should be designed according to the principles of #EN ISO 12100:2010$ for
hazards relevant but not significant, which are not dealt with by this document (e.g. sharp edges of the machine frame).
NOTE 2 For guidance in connection with risk reduction by design see #EN ISO 12100:2010, 6.2$ and for
safeguarding measures see #EN ISO 12100:2010, 6.3$.
5.2 Controls
5.2.1 Safety and reliability of control systems
#deleted text$
#For the purpose of this document, safety related part of a control system means the system from the initial
actuator or position detector or sensor up to and including the power control element of the final machine final
actuator e.g. motor or brake. Safety related parts of the control system of this machine comprise parts
concerning the following functions and they shall fulfil at least the requirements of the PL given below in
accordance with the requirements of EN ISO 13849-1:2008:$
a) for starting and restarting: #PL = c$ (see 5.2.3, 5.2.6);
b) for prevention of unexpected start up: #PL = c$ (see 5.2.9);
c) for normal stopping: #PL = c$ (see 5.2.4);
d) for emergency stop: #PL = c$ (see 5.2.5);
e) for enabling devices: #PL = c$ (see 5.3.6.4 and 5.3.7.3);
f) for hold-to-run control devices: #PL = c$ (#PL = b$ is allowed if the hold-to-run control device is
combined with an enabling device #PL = c$) (see 5.3.6.4 and 5.3.7.3);
g) for interlocking of guards: #PL = c$ (see 5.3.7, 5.3.8);
h) for interlocking of functions: #PL = c$ (see 5.2.3.1, 5.2.6, 5.2.7, 5.3.4, 5.3.7.3);
i) for speed changing and indication of the selected speed: #PL = b$ (see 5.2.7);
j) for powered movement of the saw blade, saw unit and moving beam: #PL = c$ (see 5.2.3, 5.2.4,
5.2.5, 5.2.6, 5.3.7);
k) for monitoring the operating maximum speed of the stroke of the saw unit and of the moving beam on
machines with integrated feed: #PL = c$ (see 5.2.6);
l) for powered movement of the programmable stop: #PL = c$ (see 5.3.6.4);
m) for braking: #PL = b or PL = c$ (see 5.3.4).
#Where magnetic / proximity switches are used they shall be in accordance with the requirements of 6.2 of
EN 1088:1995+A2:2008 and the related control system shall conform to at least PL = c in accordance with the
requirements of EN ISO 13849-1:2008.$
Verification: By checking the relevant drawings and / or circuit diagrams and inspection of the machine.

5.2.2 Position of controls
All electrical hand-operated controls shall be positioned ≥ 600 mm and ≤ 1 800 mm above floor level.
The electrical hand-operated controls of the machine i.e. for starting, normal stopping, cutting stroke / return
stroke (machines with integrated feed), for the programmable stop (if fitted) and for tool spindle speed
changing (if fitted) shall be positioned on the front side of the main control panel fixed at the moving beam.
The hand-operated controls for the power driven saw unit infeed / outfeed movement shall be positioned either on
the saw unit or on the front side of the main control panel fixed at the moving beam.
An emergency stop control device shall be provided on the front side of the main control panel together with the
normal start and stop controls.
For machines with integrated feed additional emergency stop control devices shall be provided at each end of the
machine frame and on any auxiliary control panel.
Verification: By checking the relevant drawings, inspection of the machine, measurement and relevant functional
testing of the machine.
5.2.3 Starting
Before starting or restarting of the machine all interlocked guards shall be in place and functional. This is
achieved by the interlocking arrangements described in 5.3.7.
For electrically operated machines the requirements of 9.2.5.2 of EN 60204-1:2006 apply but the exceptions
referred to and described in 9.2.4 of EN 60204-1:2006 are not relevant.
Start or restart shall only be possible by actuation of the start control device provided for that purpose.
#The safety related part of the control systems (see also 5.2.1) for:
a) starting or restarting the tool spindle;
b) pivoting movement of the saw unit;
c) infeed / outfeed movement of the saw unit on machines with hand feed;
d) starting the cutting cycle or for initiation of the start of the cutting cycle on machines with integrated feed
shall be at least PL = c in accordance with the requirements of EN ISO 13849-1:2008.
The safety related part of the control system for the cutting cycle movements on machines with integrated
feed shall be at least PL = b in accordance with the requirements of EN ISO 13849-1:2008.$
Only one powered integrated feed movement shall be possible at any one time.
At the end of the integrated feed / pivoting movement power is cut to the corresponding machine actuators. A
time delay device of fail safe technique may be used for cutting power with time delay corresponding to the
maximum time for the integrated feed movement #, e.g. of capacity type conforming to PL = c in accordance
with the requirements of EN ISO 13849-1:2008$. Either the time delay shall be fixed or the time delay
adjustment device shall be sealed. A new initiation shall be necessary to perform an additional integrated feed
movement.
Starting the saw unit pivoting movement shall only be possible when the saw unit is in its rest position.
Verification: By checking the relevant drawings and / or circuit diagrams, inspection of the machine and
relevant functional testing of the machine.
