GENERAL DESCRIPTION
Automatic slicing machines which are totally fused in aluminium alloy and protected by
anodic treatment.
Designed for high production levels, they can cut great amounts of products. The slicing
machines are equipped with two electric motors (one for blade rotation, one for carriage
movement) which allow both automatic and manual cutting.
They can equipped with a slice counting device with pre-selector which means the
desired number of slices can be selected, when the selected number is reached the
carriage stops; the carriage run can also be regulated so it can be adapted to the size of
the product on the food plate.
The life of the machine depends strictly on working conditions and the care
taken when using the machine.
Carefully follow the instructions for use and the maintenance norms listed
below.
Products that can be sliced: all types of cold cuts (cooked, raw, smoked), boneless
meats (cooked or raw at a temperature of not less than +3°C), bread and cheeses(those
that can be sliced, such as Gruyere, Fontina, etc.).
Products that cannot be sliced: frozen food, deep frozen food, food with bones (meeat
and fish), any other product not for consumption.

INSTALLATION
The slicing machine must be placed on a horizontal flat surface which is stable and non-
slip, suitable for sustaining the weight of the machine and the food; a support column
with top is available on request.
We advise a height of the work top of about 800-900mm.
Check that nothing gets in the way of the carriage run and loading food on to the plate.
The machine must be installed near an EEC regulation socket derived from a plant
conforming to the norms in force (magnetic thermal differential protection, grounding)
Before connection ensure that the features of the electric power supply system
are the same as those indicated on the data plate of the machine.
In the case of three-phase machines the socket must be a five-polar type:
three-phases, neutral, ground.
The machines are equipped with an electrical cable about 2 metres long, foreseen for a
plug-socket power system so that it is easy to detach the same from the electric system
in the foreseen conditions (maintenance, end of shift, anomalies…).
The presence of the power supply cord must be marked if people walk through this area.
It is forbidden to use extension cords and/or multiple sockets.
CHECKING THE ROTATION DIRECTION OF THE BLADE (THREE-PHASE MODELS)
When you plug on the electrical cable, check that the light above the off button comes on
and then start the blade by pressing the button ON.
Check that it turns counterclockwise when looking at the machine from the blade
cover disc side (21).
If the blade turns in the opposite direction (clockwise) immediately stop the machine and
call a professionally qualified person to change the position of the wires of two of the
phases at the plug terminals.
Check that the food plate (7) and food press both slide (4).
Check the function and the regulation of the thickness gauge plate (17).

USING THE MACHINE
Check that the slicer is properly connected to the electrical line and that the slice
thickness regulator is positioned on “0”.
The off button light must be on and you have to see one led on of the STROKE button
light.
Manual use:
Turn the function mode selector knob (11) counterclockwise;
Put the product to be sliced on the food plate (7) up to against the thickness gauge
plate (17) and block it;
Start the blade by pressing ON button.
Regulate the thickness of the slice as necessary (10) and start manual operation by
moving the carriage with the handle of the food plate (8).
Use the handle of the food press if the weight and the size of the product do not
allow a proper cutting.
Automatic use (push button control panel):
Turn the function mode selector knob (11) clockwise;
Put the product to be sliced on the food plate (7) up to against the thickness gauge
plate (17) and block it;
Start the blade pressing the ON button;
Regulate the thickness of the slice as necessary (10) and then start the food plate
carriage by pressing the SPEED button;
When you start the carriage movement there is only one led on for SPEED light, and
you can increase the speed pressing once or twice the SPEED button.
When you start the carriage movement there is only on led on for the STROKE light
and if you want to increase the carriage run you have to press once or twice the
STROKE button.
Note: when you push the OFF button, you stop the blade and the carriage movement.
But the slicer keeps the settings regarding speed and stroke, so when you push the ON
button the slicer restarts with the same carriage run and speed before the stopping.
If you want to stop the carriage movement, you can turn the function mode selector
knob (11) counterclockwise or you can press the SPEED button in order to have no led on
the lamp of the light speed.
You can return to the automatic mode turning again the function mode selector knob,
with the previous settings of speed and stroke.
Note: you can loose the settings only plugging off the electrical cable.
Warning: the circuit board has a thermal protector. If the circuit board reach the 80°C
temperature (if you use the slicer continuously for 4 hours without turning off, maybe it
could happen), the slicers turns off. So you have to plug off the electrical cable and you
can’t use it for 5 minutes. Then you can re-start top use it as written above.

CLEANING AND LUBRICATION
Before carrying out the cleaning and/or lubrication operations disconnected the machine
from the electricity supply and turn the slice thickness regulator to zero.
The machine must be cleaned at least once a day, more often if necessary, using only a
soft cloth dampened with hot water and a neutral washing up detergent, if needed a bush
with semi-rigid bristles can be used for the plate and the pointed food press.
Rinse off detergent using a clean cloth dampened with fresh water.
During these operations take all precautions and ware protective gloves.
Cleaning the blade: completely unscrew (counterclockwise) the blade cover disc locking
knob (21) and remove the disc; press a damp cloth over the surface of the blade and
move form the middle out towards the edge.
Warning: Use protective gloves and take extreme caution during this operation.
DANGER OF CUTTING!
Replace the blade cove disc promptly when the cleaning operations are over.
Don’t use air, water or vapour spray an do not remove other protective devices
or the food press plate.
Every week squirt a small amount of oil in the lubrication hole (1) for lubricating the food
plate carriage guides; the transversal movement of the food press (2) must be oiled in
the same way. Manually slide the units and clean as necessary removing any excess
lubricant.
Warning: only use white Vaseline oil. Do not use vegetables oils.

10
MAINTENANCE AND REPAIRS
The maintenance operations which the operator is allowed to perform are the following:
Blade grinding, periodically;
The periodicity and duration of the grinding depend on the use of the machine
(working times and type of products).
Lubrication carriage run guides, weekly;
Lubrication transversal movement of food press, weekly;
Verification of the condition of the electrical supply cable and the fairlead on the base
of the machine, periodically.
Maintenance operations to be carried out exclusively by qualified personnel authorized by
the manufacturer are the following:
Blade replacement;
Replacement of the grinder;
Replacement of the belt/s motor/s;
Replacement of electrical components under the base;
Repair of structural parts, repairs and/or replacement of mechanical components

BLADE GRINDING
The grinding operation is to be carried out after having cleaned the machine as explained
in the previous paragraphs.
Warning: blade grinding can be carried out until the distance between the blade edge and
the inside edge of the guard does not exceed 6 mm, corresponding to a decrease of
about 10 mm on the dimensional value of the original diameter. Once this is exceeded
the blade must be replaced by qualified personnel only, as authorized by the
manufacturer.
