GENERAL INFORMATION AND SAFETY

1.1.1

SCOPE OF THE MANUAL

This manual, which is an integral part of the machine (1), was prepared by the Manufacturer

to provide the necessary information to all those who are authorised to interact with it during

its life span: Buyers, System Designers, Carriers, Handling Operators, Installers, Expert

Operators, Specialist Technicians and Users.

As well as adopting a code of good practice, the recipients of the manual must read the

information with care and apply it scrupulously. Taking a little time to read this information

can help avoid risks to the health and safety of persons as well as prevent financial losses.

The information was written by the Manufacturer in the manufacturer's native language

(Italian) and is referred to as the "ORIGINAL INSTRUCTIONS". This information is also

available in English as the "TRANSLATION OF THE ORIGINAL INSTRUCTIONS" and can

be translated into other languages to meet legislative and/or commercial requirements. The

information is valid even if the machine in your possession is not exactly the same as the

one referred to.

Keep this manual in a known and easily accessible place to refer to as necessary.

The Manufacturer reserves the right to modify the product without prior notice.

A number of symbols are used to highlight some parts of the text that are of particular

safety rules in this manual and the national regulations in force.

Designer: a competent specialist person duly appointed and authorised to draw up a

project that takes into account all the legislative and regulatory aspects and code of good

practice that apply to the system as a whole. In any case, as well as comply with the

instructions provided by the machine Manufacturer, the designer must consider all the

safety aspects for all those persons who will have to interact with the system during its

expected life span.

Installer: specialist competent person duly appointed and authorised to set up the machine

or system according to the project specifications and the recommendations of the machine

Manufacturer and in compliance with the laws on safety at work.
