1.7.1. Information and warnings on the machinery
Information and warnings on the machinery should preferably be provided in the form of readily understandable
symbols or pictograms. Any written or verbal information and warnings must be expressed in an official
Community language or languages, which may be determined in accordance with the Treaty by the Member
State in which the machinery is placed on the market and/or put into service and may be accompanied, on
request, by versions in any other official Community language or languages understood by the operators. Information and information devices
The information needed to control machinery must be provided in a form that is unambiguous and easily
understood. It must not be excessive to the extent of overloading the operator.
Visual display units or any other interactive means of communication between the operator and the machine
must be easily understood and easy to use. Warning devices
Where the health and safety of persons may be endangered by a fault in the operation of unsupervised
machinery, the machinery must be equipped in such a way as to give an appropriate acoustic or light signal
as a warning.
Where machinery is equipped with warning devices these must be unambiguous and easily perceived. The
operator must have facilities to check the operation of such warning devices at all times.
The requirements of the specific Community Directives concerning colours and safety signals must be
complied with.
1.7.2. Warning of residual risks
Where risks remain despite the inherent safe design measures, safeguarding and complementary protective
measures adopted, the necessary warnings, including warning devices, must be provided.
1.7.3. Marking of machinery
All machinery must be marked visibly, legibly and indelibly with the following minimum particulars:
— the business name and full address of the manufacturer and, where applicable, his authorised representative,
— designation of the machinery,
— the CE Marking (see Annex III),
— designation of series or type,
— serial number, if any,
— the year of construction, that is the year in which the manufacturing process is completed.
It is prohibited to pre-date or post-date the machinery when affixing the CE marking.
Furthermore, machinery designed and constructed for use in a potentially explosive atmosphere must be
marked accordingly.
Machinery must also bear full information relevant to its type and essential for safe use. Such information is
subject to the requirements set out in section 1.7.1.
Where a machine part must be handled during use with lifting equipment, its mass must be indicated legibly,
indelibly and unambiguously.

1.7.4. Instructions
All machinery must be accompanied by instructions in the official Community language or languages of the
Member State in which it is placed on the market and/or put into service.
The instructions accompanying the machinery must be either ‘Original instructions’ or a ‘Translation of the
original instructions’, in which case the translation must be accompanied by the original instructions.
By way of exception, the maintenance instructions intended for use by specialised personnel mandated by the
manufacturer or his authorised representative may be supplied in only one Community language which the
specialised personnel understand.
The instructions must be drafted in accordance with the principles set out below. General principles for the drafting of instructions
(a) The instructions must be drafted in one or more official Community languages.
    The words ‘Original instructions’ must appear on the language version(s) verified
    by the manufacturer or his authorised representative.
(b) Where no ‘Original instructions’ exist in the official language(s) of the country where
    the machinery is to be used, a translation into that/those language(s) must be provided by
    the manufacturer or his authorised representative or by the person bringing the machinery
    into the language area in question. The translations must bear the words ‘Translation of the
    original instructions’.
(c) The contents of the instructions must cover not only the intended use of the machinery but
    also take into account any reasonably foreseeable misuse thereof.
(d) In the case of machinery intended for use by non-professional operators, the wording and
    layout of the instructions for use must take into account the level of general education
    and acumen that can reasonably be expected from such operators. Contents of the instructions
Each instruction manual must contain, where applicable, at least the following information:
(a) the business name and full address of the manufacturer and of his authorised representative;
(b) the designation of the machinery as marked on the machinery itself, except for the serial
    number (see section 1.7.3);
(c) the EC declaration of conformity, or a document setting out the contents of the EC
    declaration of conformity, showing the particulars of the machinery, not necessarily
    including the serial number and the signature;
(d) a general description of the machinery;
(e) the drawings, diagrams, descriptions and explanations necessary for the use,
    maintenance and repair of the machinery and for checking its correct functioning;
(f) a description of the workstation(s) likely to be occupied by operators;
(g) a description of the intended use of the machinery;
(h) warnings concerning ways in which the machinery must not be used that experience has
    shown might occur;
(i) assembly, installation and connection instructions, including drawings, diagrams and
    the means of attachment and the designation of the chassis or installation on which the
    machinery is to be mounted;
(j) instructions relating to installation and assembly for reducing noise or vibration;
(k) instructions for the putting into service and use of the machinery and, if necessary,
    instructions for the training of operators;
(l) information about the residual risks that remain despite the inherent safe design measures,
    safeguarding and complementary protective measures adopted;
(m) instructions on the protective measures to be taken by the user, including, where appropriate,
    the personal protective equipment to be provided;
(n) the essential characteristics of tools which may be fitted to the machinery;
(o) the conditions in which the machinery meets the requirement of stability during use,
    transportation, assembly, dismantling when out of service, testing or foreseeable breakdowns;
(p) instructions with a view to ensuring that transport, handling and storage operations can be
    made safely, giving the mass of the machinery and of its various parts where these are
    regularly to be transported separately;
(q) the operating method to be followed in the event of accident or breakdown; if a blockage is
    likely to occur, the operating method to be followed so as to enable the equipment to be
    safely unblocked;
(r) the description of the adjustment and maintenance operations that should be carried
    out by the user and the preventive maintenance measures that should be observed;
(s) instructions designed to enable adjustment and maintenance to be carried out safely,
    including the protective measures that should be taken during these operations;
(t) the specifications of the spare parts to be used, when these affect the health and safety of operators;
(u) the following information on airborne noise emissions:
    — the A-weighted emission sound pressure level at workstations, where this exceeds 70 dB(A);
       where this level does not exceed 70 dB(A), this fact must be indicated,
    — the peak C-weighted instantaneous sound pressure value at workstations, where this exceeds
       63 Pa (130 dB in relation to 20 μPa),
    — the A-weighted sound power level emitted by the machinery, where the A-weighted emission sound
       pressure level at workstations exceeds 80 dB(A).
    These values must be either those actually measured for the machinery in question or those established
    on the basis of measurements taken for technically comparable machinery which is representative of the
    machinery to be produced.
    In the case of very large machinery, instead of the A-weighted sound power level, the A-weighted emission
    sound pressure levels at specified positions around the machinery may be indicated.
    Where the harmonised standards are not applied, sound levels must be measured using the most appropriate
    method for the machinery. Whenever sound emission values are indicated the uncertainties
    surrounding these values must be specified. The operating conditions of the machinery during measurement
    and the measuring methods used must be described.
    Where the workstation(s) are undefined or cannot be defined, A-weighted sound pressure levels must be
    measured at a distance of 1 metre from the surface of the machinery and at a height of 1,6 metres from
    the floor or access platform. The position and value of the maximum sound pressure must be indicated.
    Where specific Community Directives lay down other requirements for the measurement of sound pressure
    levels or sound power levels, those Directives must be applied and the corresponding provisions of
    this section shall not apply;
(v) where machinery is likely to emit non-ionising radiation which may cause harm to persons, in particular
    persons with active or non-active implantable medical devices, information concerning the radiation
    emitted for the operator and exposed persons. Sales literature
Sales literature describing the machinery must not contradict the instructions as regards health and safety
aspects. Sales literature describing the performance characteristics of machinery must contain the same information on emissions as is contained in the instructions.
