Introduction
This European Standard is a type C standard as stated in EN ISO 12100-1.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this European Standard.

1 Scope
1.1 This European Standard covers portable and/or hand-guided machines and appliances equipped with
mechanically driven cutting tools.
This European Standard specifies requirements for the design and manufacture of portable and/or hand-
guided machines and appliances equipped with electrically, hydraulically or pneumatically driven cutting tools
(see Figures 1 to 9), hereinafter referred to as “machines”.
The machines covered by this European Standard are used for slaughtering animals, for cutting up animal
carcasses, poultry and other foodstuff such as e.g. fish.
They are mainly intended for use in slaughterhouses and rooms, which are used for cutting and preparing.
These machines are used for the industry and trade.
This European Standard deals with all significant hazards, hazardous situations and events relevant to
machines, appliances and machinery, when they are used as intended and under the conditions foreseen by
the manufacturer (see Clause 4).
This European Standard deals with the hazards which can arise during commissioning, operation,
maintenance and de-commissioning of the machine.
This European Standard is not applicable to portable and/or hand-guided machines and appliances equipped
with electrically, hydraulically or pneumatically driven cutting tools, which are manufactured before the date of
publication of this European Standard by CEN.
1.2 This European Standard covers the following machines subdivided into tool types:
1.2.1 Saws (see Figures 1 to 5)
 Circular saws (see Figures 1 and 2);
 straight blade reciprocating saws (see Figures 3 and 4);
 band saws (see Figure 5).

Figure 8 — Derinder Figure 9 — Flexible driven circular knife

Portable and/or hand-guided machines are constructed of a machine housing with a motor or pressure
cylinder within the housing, or a motor which drives the tool via a flexible drive cable, the tool being hand-held
at the place of use or being hand-guided on a movable device.
The motor or drive can comprise electrical, hydraulic or pneumatic components.
For weight balancing, a suspension unit with a tensioning spring or a counter-balancer can make the work
easier for the operator. This equipment is not covered by this European Standard.
1.3 Intended use
Portable and/or hand-guided machines are used on suspended or lying, stunned and blood-drained animals
for cutting off legs, feet and horns, for cutting out anuses, for skinning, for opening the sternum, for halving,
quartering or further cutting carcasses and for removing fat.
Although it should be advised against, this European Standard, taking into account practice, deals with the
hazards due to cleaning with pressurised water.
With the aim of clarifying the intentions of this European Standard and avoiding doubts when reading it, the
following assumptions were made for operation:
 only designated and instructed persons operate the machine,
 place of use is adequately lit, and
the equipment will be used in an environment with hygiene hazards but without other special hazards.

5 Safety and hygiene requirements and/or protective measures
5.1 General
Portable and/or hand-guided machines shall comply with the safety requirements and/or protective measures
of this clause and Annex B.
In addition, they shall be designed according to the principles of EN ISO 12100 for hazards relevant but not
significant, which are not dealt with by this European Standard (e.g. sharp edges).
NOTE For hazards which are to be reduced by the application of a B standard such as EN 294, EN 953, EN 1672-2,
EN 60204-1 etc., the manufacturer should carry out a risk assessment to establish the requirements of that standard
which are to be applied. This specific risk assessment is part of the general risk assessment of the machine.
Where the means of reducing the risk is by the physical arrangement or positioning of the machine the
manufacturer shall include in the information for use a reference to the reduction means to be provided, and to
any limiting value of the requirement, and, if appropriate, to the means of verification.
Where the means of reducing the risk is by a safe system of working the machinery, the manufacturer shall
include in the information for use details of the system and of the elements of training required by the
operating personnel.
5.2 Mechanical hazards
5.2.1 General
Portable and/or hand-guided machines shall be designed and constructed in accordance with the conditions
mentioned below and Annex B.
5.2.2 Zone 1 – Cutting part
5.2.2.1 Non-cutting part of circular saws
Circular saws shall be provided with guards made of a material strong enough to contain any part of a blade
which might be ejected due to failure. The guards shall have the following characteristics:
5.2.2.1.1 Circular saws shall be provided with a fixed guard (see EN ISO 12100-1:2003, 3.25.1) covering
the part of the blade which is not required for sawing for an angle β ≥ 135° and placed in such a way that
angle (see Figure 10) has a minimum value of:
α ≥≥≥≥ 15° for cutting saws
α ≥≥ 30° for other types of circular saws
≥≥

Dimensions in millimetres


Figure 10 —Fixed guard on circular saws Figure 11 —Fixed guard on horn or leg saws
5.2.2.1.2 Circular saws used for severing feet and horns shall be provided with two guides with a minimum
length of 130 mm (see Figure 11) to prevent the tool from slipping. In this case, the guard shall cover the teeth
of the blade with the angle ≥ 190° and the angle α ≥ 95°.
For this type of saw a two-hand control of at least type I, EN 574 shall be used.
5.2.2.2 Non-cutting part of band saws
Band saws shall be so designed and constructed that access to the parts of the blade which are not used
during operation is prevented by a interlocking guard with locking according to category 1 or 3 of EN 954-
1:1996 (see 3.25.4 of EN ISO 12100-1:2003).
Alternatively a two-hand control according to type I of EN 574:1996 can be used. In this case there shall also
1)
be a guard with interlocking according to at least category B of EN 954-1:1996. A PDF is a good solution for
the position sensor of the interlocking.
5.2.2.3 Stopping time
Circular saws and band saws shall stop in less than 3 s after being switched off.
5.2.3 Zone 2 – Moving transmission elements
Access to dangerous zones at moving power transmission parts shall be prevented by fixed guards in
accordance with EN 953.
5.2.4 Protective cover
The protective cover shall be designed to avoid penetration of ejected parts.

5.2.5 Other requirements
5.2.5.1 Control devices
The control device shall be of the hold-to-run type.
This requirement does not apply to flexible driven cable derinders and flexible driven machines with ring blade
circular knives with a diameter < 55 mm. It is sufficient that they switch off automatically when the appliance is
suspended and have to be switched on intentionally before use.
5.2.5.2 Two hand control
Circular saws with a blade diameter > 320 mm and shears and pincers weighing > 4 kg shall be equipped with
a two-hand control according to type I of EN 574:1996.
5.2.5.3 Hand guard
For shears and pincers weighing ≤ 4 kg, a safety device shall be fitted which minimises the probability of
contact of the non-working hand with the cutting tool. This device can be a u-shaped cover with a width of at
least 60 mm oriented to the non-working hand (see Figure 12).

Figure 12 — Fixed guard (spacer) on shear for cutting the feet of pigs
5.2.5.4 Unintended start-up
The operating switch shall be so designed, located and protected as to prevent unintentional start-up of the
tool.
This requirement can be fulfilled by e.g.:
 two keys, which generate only an output-signal, if they are activated within 0,5 s. It shall be prevented,
that both keys can be activated with one hand;
 locking system for the switch, which needs to be deliberately unlocked to switch-on, the locking shall be
achieved without delay;
 device covering the whole length of the operating switch in order to prevent unexpected start-up in case
of impact;
 equivalent system.
