Use and maintenance manual (translation of the original instructions) - MASA6_en_2 of 23/03/2021
due to oil-hydraulic pressure
G. Being splashed or sprayed with fluids under pressure (oil) or severe contusion due to whiplash if a
component breaks or a hose suddenly breaks loose, etc.
due to dust inhalation
H. damage to the respiratory tract (rhinitis, lacrimation, asthma, etc.) caused by the inhalation of flour dust
and/or other ingredients (for example, in case of flour being loaded into the flour duster without taking the
due precautionary measures)
related to hygiene
I. damage to people's health by contact with mould, rotting substances, etc., penetration of insects, rodents,
etc.
J. alterations of the food product (ex. contamination by growth of microorganisms or by foreign matter)
linked to non-compliance with ergonomic principles
K. lesions/injuries due to incorrect posture or manual handling of excessive and/or awkward loads (loading
into the hopper excessively heavy amounts of dough or dough that is difficult to handle, etc.)
The relative risks were eliminated or minimised as much as possible by adopting the safety measures and
devices illustrated in this manual (in particular in this chapter) and can be further reduced if the user conforms to
the described measures.
5.2.2 SAFETY EQUIPMENT INSTALLED IN THE MACHINE
1. AOPD on top of the hopper. It consists of two opposed elements, on the left and right sides of the hopper,
whose length is equal to the depth of the hopper itself. One of the two elements (emitter)Figure 43 ref. A
emits a series of beams that are14 mm apart from each other; the second element (receiver)Figure 43 ref. B
receives the beams emitted
by the first element and
verifies the receipt of all the
emitted beams.
The light curtain is
positioned in such a way as
to also cover the area of the
two side pockets of the
hopper that contain the
flour, which guarantees the
safety of the machine even
when the two lids are open.
The light curtain is fixed to
the hopper body by means
of screws, and protected by
suitable stainless steel
guards. The possible
interruption of even just one
of the beams emitted by the
light curtain causes the
immediate stop of the star
dosing devices and of the six
dough accompanying rollers
located inside the head, right
under the hopper Figure 37 pos. 4 and 5 respectively. The dough compression piston Figure 37 Pos. 6 will
remain in its rest position and only if it has already started its compression cycle, will it stop the work cycle and
remain blocked upon completion: this procedure was necessary to avoid the production of pieces of incomplete
weight which would be the result of the immediate stop of the compression piston when the light curtain is
interrupted. This would significantly increase the quantity of non-conforming pieces and also increase the
fragments of dough that would build-up anywhere inside the machine. During the entire interruption of the beam
generated by the light curtain, the display will show the image in figure Figure 23 and the dividing operation will
in fact be interrupted, even if the whole work cycle that follows it, will continue its course to avoid mechanical
mistreatment on the already broken pieces and in the rounding and unloading and loaf moulding phase. To
resume processing, it is sufficient to leave the area covered by the aforementioned light curtain free. It must be
said that normally, during standard use of the machine, the interruption of the beam generated by the light
curtain occurs within a fraction of a second, that is the time of falling by gravity of a new portion of dough
feeding the hopper.
2. Front door associated with a mechanical safety microswitch (for “SYNCRO E” and “SYNCRO EM”) or
with a coded magnetic sensor (for “SYNCRO” and “SYNCRO M”). Figure 13 ref. 1 and 2 to access the
