Usage and Maintenance Manual (Translation of the original instructions) –MASV7_en_0 dated 01/09/2016
1 INTRODUCTION
1.1 PREAMBLE
This instruction manual is intended to be consulted by anyone in any position 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 be able to use it as a valid support in fulfilling a part of the obligations that current laws and
regulations in force impose on them concerning safety and health 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 preparation
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 installation
This part, which covers the first paragraphs of Chapter 3, is intended for the personnel responsible for handling,
transport, and installation, and carrying out the commissioning of the machine for the purpose of providing all the
important notions, excluding those that must already be considered part of the cultural baggage of an expert
and/or professionally prepared and/or specialised technician in order to carry out the said operations.
Instructions for routine use and maintenance under safe conditions
This section, dealt with in Chapter 2 and part of Chapters 3, 4 and 5, is intended for the employer of operators
using the machine, managers, and supervisors of the company using the machine and the operators
themselves.
In addition to the instructions for ongoing use of the machine, it includes indications for maintenance, cleaning,
and monitoring operations that, due to their simplicity and low-risk involved, do not require particular experience
or professionalism and can be carried out by the machine operator for production purposes.
Instructions for extraordinary maintenance
This section of the manual, dealt with in the remaining part of Chapters 4 and 5, is intended for the employer of
the machine operators, managers, and supervisors of the company using the machine, to the operators
themselves, and to specialised personnel responsible for carrying out maintenance, routine and/or extraordinary,
of the machine. This section includes some indications, especially important for safety purposes, to follow during
maintenance, regulating, and monitoring operations that, whether for their complexity and/or risk involved,
require the intervention of specialised personnel, experts, or trained professionals with the technical-regulatory
knowledge for carrying out such work safely and according to code.
Given the specific experience that the personnel responsible for this type of intervention must have, the
information, instructions, etc. of a technical nature that are not important for safe operation of the machine
and/or the professional maintenance technician is required to know, are omitted.
Instructions for decommissioning and/or dismantling
This section is dealt with in Chapter 6.
References made to specific chapters or paragraphs must also be understood as inclusive of all the relative sub-
paragraphs; where, for example, paragraph 5.3 is cited, the reference must be considered as being extended to
all the paragraphs from 5.3 to 5.3.9.
Before carrying out any operation on/with the machine (installation, regulation, use, repair, etc.) carefully read
the general and specific instructions in this manual and understand their purposes and meanings in relation to
the correct functioning 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 attached publications in a safe place, where machine operators and/or maintenance
technicians can find it easily. Keep it in a dry place and protected from atmospheric agents that over time could
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 immediately for a copy from Artezen s.r.l., clearly specifying all the
identification data of the machine (year of construction, model, serial number, etc.).
This manual reflects the current state-of-the-art at the time the machine was put on the market or 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 of the machine 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, the first thing to do after having removed the packaging (see par. 3.2), is to
check that it is equipped with all the devices, especially the safety devices, described in this manual and
that it is in conformity with the indications made in the purchase order and/or order confirmation.

ref. 1 support structure (base)
ref. 2 hopper to contain the dough to be divided; the hopper may be equipped with:
- a safety sensor ring ref. 10 and spacer ring ref. 11 or, otherwise
- an interlocking guard (cover) to close the upper opening (see par. 2.2, Figure 3) in both cases in
conformity with the provisions of EN 12042:2014
ref. 3 vacuum and dividing unit; vacuum transfers into a chamber (vacuum chamber) a quantity of dough in
excess of the piece to be produced, then rotates to separate the mass sucked from the remaining mass in
the hopper, detaching the piece expelled by the unit’s weight chamber ref. 4, which is refilled immediately.
ref. 4 unit to measure the volume of dough of the piece to be produced; the volume of the inner chamber (weight
chamber) can be regulated either manually or in a motorised manner, depending on the version of the
machine; when the vacuum unit returns to its starting position, the volume of dough is expelled from a
piston system, hence detached and dropped onto the underlying belt by the vacuum unit, which in the
meantime carries out another cycle.
The combination of ref. 3 and ref. 4 forms the so-called “dividing unit head”
ref. 5 piece output belt; can be frontal (Calybra),like in the example of Figure 1, or to the right or left (Calybra L);
the frontal output belt (mod. Calybra) can be either single or double (see also par. 2.2)
ref. 6 control panel
ref. 7 hydraulic pumping unit (central) for the creation of hydraulic energy necessary to move the various parts of
the machine.
ref. 8 flour distributing device (flour duster); this is not part of the basic machine (optional)
ref. 9 box containing the electrical panel.

For the instructions on how to use the “Memory Pack” control panel, shown in Figure 8/A, consult the
attached “Appendix Memory Pack” manual. In this version, the weight chamber appears as in detail B, where for
greater clarity the casing is represented as being transparent; obviously the manual adjustment flywheel is
missing (ref. 1 Figure 24) since the adjustment is done using a dedicated motor.
The functions of ref. 3 and ref. 4 devices are the same as the devices shown Figure 5 and Figure 6
Figure 8 - “Memory Pack” Control Panel
2.4.4 «V» BELT RELATIVE SPEED CONTROL DEVICE
In the configuration with “V-belts”, the control panel is equipped with a potentiometer on the side, as shown in
Figure 9,) that makes it possible to vary the speed of one of the two belts and, therefore, the relative speed
between the belts. By moving at different speeds, the belts tend to roll on themselves the pieces of dough
moving towards exit, giving them a partial rounding effect (pre-rounding); this can be very useful for some types
of dough before sending the pieces into the next phase of production.

3 INSTALLATION AND USE
3.1 INSTALLATION SITE REQUIREMENTS
The place where the machine will be kept and/or used must conform with current laws in force and ensure
adequate protection from impacts, damage, deterioration and atmospheric agents. The access must have the
dimensions and characteristics to enable easy and safe passage of the machine without people or the machine
itself being put at risk. Flooring, support structures, and walls must be in conformity with current building codes
and laws in force, also in consideration of the total load to bear and relative safety coefficient; they must be easy
to clean, disinfect, and disinfest. The floor must be level, not sloping, compact, and with no holes or unevenness.
The electrical system and the earth of the site must conform to current building codes and laws in force, as well
as constructed, maintained and, if required by law, controlled by authorised and professionally qualified
technicians capable of issuing relative declarations of conformity. The upstream power supply panel must have
suitable protection devices against overloads and phase-phase, phase-neutral (if applicable), and phase-earth
malfunctions.

Usage and Maintenance Manual (Translation of the original instructions) –MASV7_en_0 dated 01/09/2016
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 maritime transport) 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 its movement during transport; the load must also be tied from 2/3 of the total height of the
wood and above to points on the means of transport that are sufficiently resistant to prevent overturning.
For handling the load packaged in the wooden crate, use a forklift truck with a capacity adequate for the mass
(see par. 2.2, Table 1); insert the lift arms inside the wood crossbars of the lower ends and as close as possible
to them, so as to prevent unwanted movement to the side; the arms of the forklift must protrude at least 200
mm from the other side.
Remove the walls of the wooden crate (it is sufficient to remove the nails from the boards, taking care with the
protruding nails) and free the machine from its wrapping (plastic strip or barrier bag). Separate materials by type
(plastic, wood, etc.) and bring them to the appropriate places accessible only to authorised persons, while
awaiting for disposal by specialised companies, as these materials must be disposed of in conformity with any
pertinent laws in force (even the wooden base must be treated in the same way, once the machine has been
removed from on top of it).
In Italy and many other States, in particular the European Union, the disposal of waste according to
precise regulations and with respect for the environment are obligations unequivocally established by
laws in force.
Check that the machine and all its parts are in good condition; in case of doubt, contact the manufacturer. With
reference to Figure 11, to release the machine from the wooden base where it is fixed:
- wear protective gloves, helmet, steel-capped safety shoes with anti-perforation soles
- use pliers to hold the threaded rod firmly ref. 1 and then use a wrench to loosen the nut ref. 2; do the same on
the other side; at this point the machine is free from the wooden base ref. 3
- pull the threaded rod ref.1 upward and save the nut and washer ref.2
- holding the crossbar ref. 5 with one hand, remove both the screws from both sides ref. 4; finally, remove the
crossbar ref.5. It is now possible to move the machine from the wooden base ref. 3 as indicated below.
Figure 11 –How to release the machine from the wooden base of the packaging
To move the machine (for example, to place it on the ground after having released it from the base of the crate),
insert the arms of the forklift truck under a side of the machine (in correspondence to the side opposite the
lateral output belt if it is a mod. Calybra L) inside the resting points (wheels) and as close as possible to the
same, as illustrated in Figure 12. The arms of the forklift must protrude at least 200 mm from the other
side.

3.3 ASSEMBLING/DISSASEMBLING THE SPACER RING
This paragraph does not apply to machines equipped with a hopper with interlocking cover, but only to those with
a hopper with a sensor ring.
For packaging reasons, the machine is shipped with the spacer ring disassembled.
It is absolutely prohibited to connect the machine to any power supply without first having assembled
the spacer ring and controlled that it has been fixed correctly with the frequency indicated here (see par.
5.2.3, point 4); this condition is absolutely necessary for ensuring an adequate level of safety when using
the machine and containing risks related to the safety of exposed persons within acceptable limits (as
required by harmonised standard EN 12042:2014).
The operation must be carried out with the power supply disconnected (always leave the plug in a highly visible
location) by specialised technicians expert in mechanical assembly.
For assembling the spacer ring, the contemporary intervention of a team of two operators is necessary; the
operators must wear steel-capped safety shoes and anti-abrasion protective gloves.
The tools necessary for this operation are easily found on the market, as listed below:
Nr.1 Allen wrench 2.5.
Nr.1 Allen wrench 4.
Nr.1 Wrench 10.
With reference to Figure 13, inside the packaging there are:
- nr. 1 spacer ring ref.1
- nr. 1 set of bolts and nuts ref.2 contained in a bag hanging from the main switch of the machine.
Points of insertion of the forklift arms; they must protrude at least 200 mm on the other side.
ATTENTION
Never use lifting systems and/or devices other than those described herein.
When moving 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.

Usage and Maintenance Manual (Translation of the original instructions) –MASV7_en_0 dated 01/09/2016
Figure 13 –Spacer ring assembly kit
With reference to Figure 14, for the assembly of the ring, proceed as follows:
1) Remove the screw ref. 1 and remove the cover ref. 2 of each of the two boxes ref. 3 inside of which there
are the micro-switches ref. 12 associated with the safety sensor ring ref. 5 (Figure A - B)
Beginning Figure 14 –
2) Slip the spacer ring ref. 6 from the top down, tipping and shifting it (arrow ) to avoid the boxes ref. 3 and the
supports ref. 4 protruding from the hopper and the sensor ring ref. 5 (Figure C); take care not to damage the
parts.
3) Once the ring is in place, turn it until the brackets ref. 7 are aligned with the boxes ref. 3 and the supports ref.
4 (arrows ); then lift it (arrows ) so that the brackets ref. 7 fit onto the sides of the boxes ref. 3 and the
supports ref. 4 (Figure D)
4) Align the holes ref. 8 of the brackets ref. 7 with the holes ref. 9 of the boxes ref. 3 and the supports ref. 4;
insert the screws in the aligned holes ref. 10, screw the nuts to the opposite sides ref. 11 with the relative
washers (Figure D - E); block everything with the wrench indicated at the beginning of the paragraph. Check
thoroughly and several times that the screws and corresponding nuts have been tightened correctly.
5) Reposition the n. 2 covers ref. 2 on the boxes ref. 3 and fix them with the screws ref. 1 (Figure F).
6) Finally, check that the ring is firmly in place and fixed to the hopper; when attempting to move it, there should
be no anomalous slack or shifting.
