manufacturer has complied with the applicable laws as well as the code of good
manufacturing practice. The purpose of this manual is to encourage users to take all due
care and thereby avoid any risks. In any case, prudence is required at all times. Safety is
also the responsibility of all operators who interact with the machine.
Carefully read the instructions in this manual and those applied directly on the machine, and
respect those concerning safety in particular.
An overall project that envisages implementation of this machine in a system must take into
account the code of good practice as well as the legislative and regulatory aspects.
Particular attention must be paid to all the recommendations and technological information
provided by the Manufacturer. Do not tamper with, avoid, remove or bypass the safety
devices installed on the machine. Failure to observe this requirement could result in serious
risks to the health and safety of the persons involved.
The personnel who carry out any kind of work during the entire life span of the machine
must have precise technical knowledge, special skills and recognised experience in the
specific sector. Non-fulfilment of these requirements could endanger people's health and
safety.
Keep the area around the machine in a good state in order to avoid risks to the health and
safety of persons during normal use and maintenance of the machine.
Some processes may require the assistance of one or more helpers. In which case, these
helpers must be duly trained and informed of the type of work to be carried out in order to
avoid risks to their health and safety.
Handle the machine in accordance with the information on the packaging.
When handling, if the circumstances demand it, request the assistance of one or more
helpers who can give directions.
The personnel who carry out loading, unloading and handling of the equipment must have
recognised skills and experience in the specific sector and must have absolute command of
the lifting equipment to be used.
During installation, observe the clearances indicated by the Manufacturer and take into
account all the work activities carried out in the vicinity. Installation must also be carried out
in compliance with the laws in force on safety at work.
The machine must be installed and connected in accordance with the Manufacturer's
instructions. The person in charge must also take into account all regulatory and legislative
requirements, carrying out all installation and connection operations in a workmanlike
manner.
After installation and before commissioning the machine, he must perform a general check
to make sure that these requirements have been met.
Check that any means of transport to be used for transfer of the machine are suitable for
the purpose, and that the machine is loaded and unloaded with care to ensure the safety of
the operator and of any other persons who are directly involved. Before transfer, make sure
that the machine and its components are duly anchored to the vehicle and do not exceed
the maximum permitted dimensions for transport on the vehicle. Apply any necessary signs.
The operator must have read and understood the information on use of the machine, and
have suitable skills and experience for carrying out the work in hand.
