4GENERAL DESCRIPTION
The LIRA and LIRA PLUS Semi-Automatic Cutters are intended for use in the food processing
industry to cut food and/or sweet products.
The cut width depends on the thickness of the cutting frames used. To this end, interchangeable
cutting frames are available.
Cutting is achieved by a reciprocating tray that moves the product past the stainless steel cutting
blades of the frame. Hence the cutting tools are static, whereas the tray on which the product to be
cut is placed goes back and forth.
The cutting speed is controlled manually, whereas the tray motion is controlled electronically.
The machine is powered by 230 V AC through a tripolar plug (including a ground terminal).
Besides the electric power circuit (230 V AC) feeding the electronic control card and the electric
engine through an inverter system, which moves the product past the cutting blades, the machine is
equipped also with an auxiliary circuit (12 V DC and 8 V DC) powering the safety and protection
relays, the control and operating unit through a transformer integrated into the motherboard.
The control panel is located on the front left side of the machine. Controls include power on/off,
cutting speed setting, return to rest position, emergency stop, and power supply indicator.
Equipment includes also a plastic top cover and a cutting frame rack.

5INTENDED USE
The Semi-Automatic LIRA and LIRA PLUS Cutters are intended for use in the food processing
industry to cut soft solid food and/or sweet products, products prepared with nut grains and having a
soft texture, or hard mixtures.
Both cutters are designed for use inside of a building. They can be placed on a flat surface or on
their own stands.

5.1 Risks associated with misuse
Follow the tips below to preserve your machine in good order and avoid any risks.
Misuse
Associated risk
Do not cut products that do not fit in the tray or
do not pass past the cutting blades
Loss of product
Do not use water spray systems to clean the
cutter with the components in place
Breakage/failure of components, risk of
electrocution
Table Error! Reference source not found..1: Misuse
5.2 Residual risks and safety measures
The cutter should be used in suitable lighting conditions since it does not have a lamp.
Before pushing the start switch, make sure the cutting frame is properly mounted on the supporting
system in order to prevent uncontrolled displacement from the installed position.
Even if the machine is equipped with safety measures and emergency stop with power
disconnection, the operator must stand in front of the cutter so that he can have full view of the
control panel. At the end of each working cycle the cutter must be stopped by pushing the ‘stop’
button and the emergency mushroom push button. Then it has to be disconnected from the mains
power supply.
5.3 Danger and safety labels
The following danger and safety labels are applied on the machine:
CAUTION. RISK OF ELECTRIC SHOCK – DO NOT OPEN
CAUTION. WATCH YOUR FINGERS AND YOUR HANDS.
READ THESE INSTRUCTIONS BEFORE SWITCHING ON THE
MACHINE FOR THE FIRST TIME.
READ THESE INSTRUCTIONS BEFORE USING THE MACHINE.

healthy or are not insured against employment injuries.
Before turning the cutter on, make sure that it functions properly.
Do not make a hole, cut or alter the machine.
Keep your hands off the cutting frames and do not rest them on the cutter while it is running.
In case of possible danger to persons or damages to the machine, press the emergency push button
to turn the cutter off.

The following checks have to be carried out regularly on the protection and safety devices:
•emergency stop and cycle restart;
−start a new working cycle;
−push the EMERGENCY STOP BUTTON;
−make sure the machine stops;
−release the EMERGENCY STOP BUTTON;
−push the START switch;
−make sure the working cycle restarts;
•working cycle stop upon lifting the protection top cover from the tray:
−start a new working cycle;
−lift the protection top cover while the tray is moving;
−make sure the working cycle stops.
Repeat the above check-ups every six months.
7.5 Starting-up
Make sure the cutter is adequately connected to the mains supply, and that the following are met:
−the machine is plugged into a standard, single-phase 10 amp (minimum) wall socket with a
ground terminal;
or alternatively
−the machine is plugged into an industrial, single-phase 10 amp (minimum) wall socket with
a ground terminal;
−switch the machine on by pushing the general on/off button (green/red) located on the back,
next to the Emergency mushroom push button;
−push the start button on the control panel;
−make sure the green light (LIRA cutter) OR the blue light (LIRA PLUS cutter) on the
START button are on.
Now the machine is powered and ready for use.
7.6 Use
The procedure can be seen also on the demonstration CD.
Lift the protection top cover.
Apply the cutting frame.
Place the product on the tray.
Pull back down the protection top cover.
Set the cutting speed by rotating the speed/power control dial (LIRA cutter) or pressing the – and +
buttons (LIRA PLUS cutter) on the control panel.
Turn the mode selector dial right (LIRA cutter) or press the ⇒switch (LIRA PLUS cutter) on the
control panel. Cutting begins and goes on until the end stroke is reached as automatically signalled
by the control system.
Remove the cut product by lifting the product recovery tray.

Chocolate World User and maintenance manual Semi-automatic cutters
Page 15 of 17
Then bring the selector mode back to the initial position and then turn it left (LIRA cutter) or press

The cutter must be cleaned after every single use, that is at the end of each continuous sequence of
use, regardless of the time it has lasted. In short, under optimum temperature and moisture
conditions for bacterial growth, all food residues have to be removed within two hours.
Always disconnect the cutter from the mains supply before cleaning it as described above.
Use preferably a vacuum cleaner to remove coarse particles from the machine body and the
components.
Use standard clearing solutions to clean the machine.
