hopper. The test is simple, easy and safe to perform thanks to the mirror installed on the upper edge of the
hopper, useful when checking the level of dough inside the machine, facilitating its loading without the aid of
ladders. Thanks to such mirror, this test performed without dough allows having a full view of the movement
of the star dosing devices without having to access from the top using ladders. If, while the machine is
running, a hand is interposed between the two opposing elements constituting the light curtain for a depth of
1 cm from the upper edge of the hopper, the rotation of the two star dosing devices and of the six rollers for
accompanying the dough, Figure 10respectively pos. 4 and 5 is stopped - if moving - or is kept stationary if
the star dosing devices were already stationary when the light curtain was interrupted; they will be kept in
this condition for as long as the hand (or any other element) remains between the two opposite elements
making up the light curtain. If case of a negative outcome, do not use the machine and ask for the
intervention of a specialised technician expert in electrical systems on-board machines.
2. Checking the efficiency ofof the microswitch or coded magnetic sensor associated with the front
door. Refer to Figure 13 ref. 1. Carry out the test when the hopper is empty (no dough) If the door is opened
by more than 2 mm while the machine is running, the machine must stop immediately. Close the door and
press start: the machine does not start. Press the RESET button indicated as ref. 1 in Figure 4 and press
start: the machine should now start. This is also used to verify the efficiency of the RESET function. If case
of a negative outcome, do not use the machine and ask for the intervention of a specialised
technician expert in electrical systems on-board machines.
3. Checking the efficiency of the microswitch associated with the rear door. Refer to Figure 13 ref. 5.
Carry out the test when the hopper is empty (no dough) If the door is opened by more than 4 mm from its
upper edge while the machine is running, the machine must stop immediately. Close the door and press
start: the machine does not start. Press the RESET button indicated as ref. 1 in Figure 4 and press start: the
machine should now start. This is also used to verify the efficiency of the RESET function. If case of a
negative outcome, do not use the machine and ask for the intervention of a specialised technician
expert in electrical systems on-board machines.
4. Checking the efficiency of the microswitch associated with the mobile sliding guard placed on the
loaf moulder. Refer to Figure 13 ref. 3. By sliding the aforementioned movable guard to the right, the
machine must stop when it opens by 2 mm. Close the sliding mobile guards and start: the machine does not
start: Press the RESET button indicated as ref. 1 in Figure 4 and press start: the machine should now start.
This is also used to verify the efficiency of the RESET function. If case of a negative outcome, do not use
the machine and ask for the intervention of a specialised technician expert in electrical systems on-
board machines.
5. Checking the efficiency of the mobile safety bar at dough outfeed (only for “SYNCRO” e “SYNCRO
E”). Refer to Figure 13 ref. 6. While the machine is running without dough, apply a slight pressure of 50 N
(approx 0.5 kgf) in the horizontal direction towards the bar, such as to slightly rotate the aforementioned bar
by moving it by 5 mm: the machine must stop. Release the bar and press start: the machine does not start:
Press the RESET button indicated as ref. 1 in Figure 4 and press start: the machine should now start. This is
also used to verify the efficiency of the RESET function. If case of a negative outcome, do not use the
machine and ask for the intervention of a specialised technician expert in electrical systems on-
board machines.
6. Fixed guards. Visually check that they are in their place, in good condition (without cracks, noticeable dents,
etc.) and locked with all the fixing means provided (screws, key systems, etc.). In case of a negative
outcome, do not use the machine and request the intervention of a technician specialised in
electrical equipment installed on board the machine; if necessary, contact the manufacturer.
7. Checking the emergency stop push-button. Carry out the test when the hopper is empty (no dough) Start
the machine and press the emergency push-button while the components are moving: the machine must
stop very quickly (in under 0.35 seconds) and the push-button must be mechanically held in position. Reset
the push-button and press start: no part should start moving. Press the RESET button indicated as ref. 1 in
Figure 4 and press start: the machine should now start. This is also used to verify the efficiency of the
RESET function. In case of a negative outcome, do not use the machine and request the intervention
of a technician specialised in electrical equipment installed on board the machine.
5.3 RESIDUAL RISKS
To minimise as much as possible the residual risks illustrated in the following sub-paragraphs, the information,
specific instructions, and training of the operators are of vital importance It is the responsibility of the
employer to provide the operators with adequate information concerning the residual risks that using
the machine implies, as well as to provide the instruction and training on its safe use, on the
precautions to be taken and the behaviours to be avoided.
5.3.1 RESIDUAL MECHANICAL RISKS
Shearing, crushing, cutting: between the dough dividing components, while passing through the hopper.
The hopper with light curtain meets the requirements of the harmonized standard EN 12042: 2020; however, a
residual risk persists for the safety of exposed persons because the top of the hopper remains completely open
and, even if the access through the opening generates the immediate stop of the two star dosing devices and of
