Safety information

Failure to comply with basic safety rules and precautions could cause
accidents during machine operation, maintenance and repair. An accident can
often be avoided by recognising potential hazardous situations before they
occur. The operator has to pay attention to potential hazards and have training,
competences and correct tools to carry out these tasks properly.

The improper use of the machine either during operation or maintenance could
be dangerous and cause serious accidents.

Do not operate the machine or carry out maintenance until these instructions
have been read and understood.

Safety precautions and warnings are given in this manual and indicated on the
machine. If the operator does not pay attention to these warnings he could
have an accident with serious consequences for himself and others.

Environmental conditions allowed

To guarantee its correct operation, the “LB 1000” machine must be positioned
in a place protected from atmospheric agents (rain, hail, snow, fog, dust etc...)
with an environmental temperature between 0°C and 32 °C and with relative
damp not above 70%.
The working environment must be clean, sufficiently bright and free from
explosive or corrosive atmosphere.

Storage / Warehousing

Store the “LB 1000” machine in a place protected from atmospheric agents with
temperatures between 0°C and 40°C, possibly in the original packing or by
protecting it with nylon sheets to avoid the accumulation of dust.

Demolition / Scrapping

General information

1

5/6

Transport

The demolition happens at the end of the working cycle of the machine that in
normal conditions of use and maintenance should last more than 10 years.
In case of demolition all the components must be disposed in appropriate
dumps following the law in force. Before demolition it is necessary to separate
the different parts (plastics or rubber, electric and electronic material etc...).
The section made of plastic, aluminium and steel material may be recycled..

Loading and unloading operations and in general all handling operation of the
