Use and maintenance manual (translation of the original instructions) - MASA6_en_2 of 23/03/2021
1 INTRODUCTION
1.1 FOREWORD
This instruction manual is intended to be consulted by anyone who is in any way responsible for or
authorised to use and/or operate the machine. It is also intended for employers, managers, and
supervisors of the company using the machine, who must carefully read and understand every part of this
manual so as to use it as a valid support in fulfilling part of the obligations imposed on them by the current laws
and regulations on health and safety in the workplace.
The employer of the personnel authorised to use the machine, the managers and the supervisors must
guarantee the operators adequate information and training, as well as practical experience (such training and
information must be simple and understandable for those involved) concerning the correct and safe use of the
machine and the generic and specific risks involved in the workplace and/or in carrying out specific tasks.
The manual is divided into different sections, which can be generally summarised as:
Instructions for handling, transport and maintenance
This section is dealt with in the first few paragraphs of Chapter 3, and is intended for the operators in charge of
handling, transporting, installing and starting-up the machine. Its purpose is to provide any significant
information required to correctly carry out such operations, with the exclusion of those that are already part of
the cultural background of an expert, and/or professionally skilled and/or specialized technician.
Instructions for using and carrying out the routine maintenance on the machine in a safe manner
This part, dealt with in Chapter2 and in part of Chapters3,4 and5, is intended for the employer of machine
operators, for the managers and supervisors of the user company, and for the operators.
In addition to the instructions for the correct use of the machine, it also includes the instructions to follow for the
maintenance, cleaning and testing operations which, due to their simplicity and the very limited danger involved,
do not require particular experience or professional background and can be performed by the operator.
Instructions for extraordinary maintenance
This part, dealt with in the remainder of the Chapters4 and5, is intended for the employer of machine operators,
for the managers and supervisors of the user company, and for the operators as well as for the specialized
personnel in charge of carrying out routine and/or extraordinary maintenance on the machine. It also contains
some important instructions on safety that must be followed for maintenance, adjustment and testing operations
which, due to their complexity and/or dangerousness require the intervention of specialized, expert,
professionally trained personnel who are in possession of all the technical and regulatory information for
perfectly and safely performing the work.
Given the necessary specific experience that the personnel assigned to this type of intervention must possess,
all the instructions of a technical nature that are not instrumental to performing the work safely and which - due
to their professional profile - such personnel must be aware of, have been omitted for obvious reasons.
Instructions for de-commissioning or dismantling
This part is covered in Chapter 76.
References made to certain chapters or paragraphs must also be understood as references to all related sub-
paragraphs; where, for example, par. 5.3 is mentioned, the reference must be understood as extended to all
paragraphs from5.3.1 to5.3.9.
Before carrying out any operation on/with the machine (installation, adjustment, use, repair, etc.) carefully read
the general and specific instructions in this manual and understand their purposes and meanings in relation to
the correct operation of the machine, its correct maintenance, and gain an adequate knowledge of the safety
devices it is equipped with and the potential residual risks its use implies.
Keep this manual and all other attached publications in a safe place, which is known to those assigned to its
use and maintenance. Keep it in a dry place and protected from atmospheric agents that over time may cause it
to deteriorate (for example, in an opaque plastic bag); it is recommended that a copy be kept near the machine
where operators can consult it quickly.
In case of loss or deterioration, ask Artezen S.r.l. to send a new copy, clearly specifying all the
identification data of the machine (year of manufacture, model, serial number, etc.).
This manual reflects the current state-of-the-art at the time the machine was put on the market or at its
commissioning, and cannot be considered inadequate only because the model was successively updated in
keeping with new experiences and new technical developments.
The manufacturer cannot be held responsible for the suitability of the installation site and the support services
therein, although important indications for a correct installation are provided in this manual. The company
reserves the right to make updates to the machine and this manual without any obligation to update any
machines and/or manuals previously produced. ATTENTION
Upon receiving the machine, remove the packaging (see par. 3.2), and immediately check that it is
equipped with all the devices, in particular the safety devices, illustrated inthis manual, and that it
complies with the indications on the purchasing order and/or in the order confirmation.
This manual is an integral part of the machine and must accompany it if it is moved or transferred for any
reason whatsoever, even free of charge.
Par. 2.1indicates the intended use of the machine with details on permitted and prohibited uses.

The 2-row divider and rounder model Syncro is intended to be used for dividing the dough consisting of
food ingredients such as flour, water, salt, yeast, into equivalent pieces, arranging them on 2 rows, then
rounding the product before it is deposited onto the exit belt; this machine was therefore conceived for the
production of bakery and pastry products. The version equipped with the final loaf moulder (Version
“SYNCRO M” and “SYNCRO EM”) is also able to subject the dough to a final crushing for obtaining products
such as Hamburger buns and/or, as an alternative, to elongation of the dough ball to obtain the Hotdog bun.

Use and maintenance manual (translation of the original instructions) - MASA6_en_2 of 23/03/2021
For safety, health and warranty reasons it is prohibited to use the machine for products and / or materials
and / or in ways other than those illustrated in this manual or, in any case, for operations not relevant to its
intended use. Any other use that is different from the declared one is considered incorrect, not in
compliance and not intended by the manufacturer and, as such, potentially hazardous for the safety and
health of exposed people, as well as of animals and property.
The basic components of the machine are (seeFigure 1):
ref. 1. load-bearing structure (base)
ref. 2 hopper for containing the dough to be portioned; on its two sides (left and right), it is equipped with flour
containers (pockets) necessary for the correct processing of the dough inside the machine. A tilt-
adjustable mirror is installed at its top. The safety light curtain is located on the two sides.
ref. 3 head unit for pre-dosing the dough; by means of a pair of star-shaped dosing devices, the dough is
conveyed vertically downwards into a compression chamber equipped with a piston - operated by an oil-
hydraulic system - that pushes the dough towards the diving drum unit ref. 4.
ref. 4 dividing drum unit, for determining the volume of the dough pieces to be produced. The dividing unit
consists of a cylindrical element (dividing drum) equipped with radial grooves (pockets), the depth of
which is variable and can be determined by adjusting the position of the same number of mobile pistons
sliding inside the aforementioned pockets. The adjustment of the volume of the pockets is motorized. The
dividing drum rotates continuously around its central axis; this movement generates the repetitive
alignment of the filling pockets with respect to the piston of the dough compression chamber; the pockets
are thus filled during this processing phase. When the rotation of the drum exposes the pockets
downwards, an ejection cam moves the pistons of the pockets also downwards, thus ejecting the dough.
ref. 5 dough-releasing rollers, removable Consisting of a unit that can be easily removed from the work area,
which, by continuously rotating in the opposite direction, helps the pieces of dough ejected from the
dividing drum to move between these two rollers, in order to facilitate the filling of the rounding cups ref. 6.
ref. 6. rounding cups unit. Consisting of a certain number of plastic blocks internally hollowed with a polygonal
geometric shape, whose depth is adjustable by means of internally sliding moulds; they are connected to
each other by a pair of chains which guarantees their alternating movement, in order to carry the pieces
of dough towards the rounding area ref. 7, and then towards the outfeed area ref. 9
ref. 7 rounder
ref. 8 control panel
ref. 9 transfer/outfeed belt
ref. 10 loaf moulder, present exclusively in the “SYNCRO M” and “SYNCRO EM” versions. It is equipped with
two parallel moulding belts arranged horizontally at an adjustable distance, which allow processing the
rounded pieces of dough in order to crush them (to obtain products such as hamburger buns) or to
elongate them (to obtain products such as hot dog buns). This version is equipped with an additional flour
duster ref. 11 located on the top of the loaf moulder.
ref. 11 flour dispensing device (flour duster)
ref. 12 box containing the power electrical panel

2.4.1 SECONDARY STOP CONTROL PANEL
The machine secondary stop control panel Figure 5 is located in the unloading area of the processed product. It
is installed exclusively in the “SYNCRO M” and “SYNCRO EM” versions as the working position of the operator
for these machines is particularly distant from the main control panel; the presence of this secondary control
panel thus improves the ergonomics when stopping the machine. It consists of a STOP only control, ref. 12, and
of an additional EMERGENCY STOP control, ref. 2

3 INSTALLATION AND USE
3.1 INSTALLATION ROOM REQUIREMENTS
The place where the machine will be kept and/or used must conform to the current laws in force and ensure
adequate protection from impacts, damage, deterioration and atmospheric agents. The dimensions and
characteristics of the access points must allow the easy and safe passage of the machine without people or the
machine itself being put at risk. The characteristics of the flooring, load-bearing structures and walls must
comply with the laws and regulations in force, also in consideration of the total load to be withstood and the
relative safety coefficients; they must be easy to clean, disinfect and disinfest. The floor must be flat, not
sloping, compact, without holes and roughness. The electrical system and the equipotential protection system
(earth) of the site must conform to the laws and standard currently in force, and must be constructed,
maintained and, if required by law, verified by authorized and professionally qualified technicians accredited to
issue the relative declarations of conformity. The upstream power supply panel must have suitable protection
devices against overloads, short-circuit, phase-phase, phase-neutral (if applicable), and phase-earth
malfunctions.
3.2 TRANSPORT, HANDLING AND POSITIONING
Depending on the destination and the contractual agreements, the machine is sent wrapped with protective
plastic material, or (in the case of sea freight) in a “barrier bag” and closed in a wooden crate firmly blocked to
the base of the same.
The load is blocked on the surface of the means of transport with crossbars and/or wooden blocks suitably
positioned to prevent it from moving during transport; the load must also be tied from 2/3 of the total height of
the wooden crate upward to points on the means of transport that are sufficiently resistant to prevent it from
overturning.
For handling the load packed in the wooden crate, use a forklift truck with a capacity adequate for the
mass (see par. 2.2,Table 1 ); insert the forks inside the lower wooden crossbars and as close as
possible to them, so as to prevent unwanted movement to the sides; the forks of the forklift must protrude
by at least 200 mm from the other side The pallet lifting area is accessible by the forks from the special
opening on the sides of the pallet Figure 7.
Remove the sides of the crate (just unscrew the boards, paying
attention to the protruding nails) and free the machine from the
wrapping (stretch plastic film or barrier bag). Separate the
materials by type (plastic, wood, etc.) and take them to dedicated
places, accessible only to authorized persons, pending disposal
by specialized companies, which must take place in compliance
with any laws in force on the subject (also the wooden base must
be treated in the same way once the machine has been removed
from it).
In Italy and other States, especially within the European
Union, waste disposal according to precise rules and
respect for the environment are obligations unequivocally
established by the applicable legislation.
Make sure that the machine is intact in every part; in case of
doubt, contact the manufacturer.
With reference to Figure 8, to release the machine from the
wooden base on which it is blocked proceed as follows:
wear abrasion-resistant gloves, helmet, shoes with
reinforced toe and anti-puncture outsole
use a forklift to stabilize the machine in its resting
position on the transport pallet: the forks of the forklift must be inserted into the rectangular slots placed
both on the front of the machine and on the rear. Make sure that the forks of the truck protrude on the
opposite side by at least 200 mm from the machine profile
Unscrew the nuts at the top of the threaded rods visible in Figure 8 ref. A and B, then take out the
threaded rods. A 19 mm hex wrench is sufficient to unscrew the threaded nut. If the threaded rod
rotates around itself while loosening the nut during unscrewing, which would make any attempt to
remove the threaded nut vain, just use a pair of pliers to stop it from rotating.
Next, unscrew the threaded nut locking the machine to the pallet, located on the rear side Figure 8 ref.
C, then pull out the threaded rod. A 19 mm hex wrench is sufficient to unscrew the threaded nut. If the
threaded rod rotates around itself while loosening the nut during unscrewing, which would make any
attempt to remove the threaded nut vain, just use a pair of pliers to stop it from rotating.

To remove the machine from the support pallet, after having inserted the forklift arms (forks) in the appropriate
slots (making sure that they protrude from the rear side of the machine by at least 200 mm), lift the machine by
about 150 mm, then move the machine and place it slowly on the supporting floor. See also Figure 9.

3.3 ELECTRICAL CONNECTION
Any electrical operation concerning the machine and / or the work site must be carried out by specialized and
expert technicians, familiar with the technical and regulatory notions to perform the work in a workmanlike
manner and in safe conditions, according to the laws in force; they must issue any declaration of conformity
required by the law.
Upon delivery of the machine, and in any case before proceeding with the electrical connection, make sure that
the line voltage corresponds to the one declared by the manufacturer on the plate (par. 2.5) and on the
wiring diagram.
The machine is supplied with an electric cable with a 5-pole 16 A plug (L1 + L2 + L3 + N + PE).
The site's electrical system must have suitable characteristics for maximum load absorption For the connection,
the user must provide a socket in compliance with the laws and regulations in force and powered with
conductors of adequate cross-section on the basis of the data given in this manual and in the wiring diagram.
Use the appropriate earthing system, whose efficiency must be periodically checked; do not connect to gas or
water pipes or other generic metal parts. Keep the power cord away from hot and / or moving parts; it must not
obstruct the passage of people, animals, things. The plug must be easily accessible and clearly visible from any
position in which the operator may be, even for a short time.
3.4 PRELIMINARY CHECK
Some machine parts must be removed to be cleaned and must be put back in place once the sanitizing
operations have been completed. With reference to Figure 10,
Open the front doors;
Remove the front cover of the head (Pos. 1) by sliding the bridge handle in the direction of the arrow;
Open the bottom door (Pos. 2) by turning the locking lever in the direction indicated by the arrow and tilt
the door downward;
Check the presence and correct installation of:
oThe brush (Pos. 3);
oThe two star dosing devices (Pos. 4);
oThe 6 dough accompanying rollers (Pos. 5);
oThe dough compression piston and relative locking pin (pos. 6);
oRemovable dough removing roller unit (in this case, failure to install the roller unit would
generate an alarm situation and the inability to start processing; the display would show the
image here below). In any case, check that the unit is correctly fitted in its seat in a stable
manner and locked in position by means of the locking lever.
ATTENTION
Never use lifting systems and/or devices other than those illustrated in this manual.
When handling and/or transporting the machine, take every possible precaution in order to prevent,
or reduce as much as possible, the occurrence of risks to persons, animals, or property.
