4.3 General description
The slicing machine has been designed and made according to the EEC Directive 2006/42. The machine
offers the user:
-maximum safety when in use, during cleaning and ordinary maintenance;
-maximum hygiene from the use of stainless materials or adequately protected against
oxidization together with an attentive design of all the parts that come into contact with food;
-maximum cutting precision and capacity together with sturdiness and reliability of the
structure;
-the chance to work continuously.
The machine is essentially made up of a base that holds a circular blade that is inclined, operated by an
electric motor, which slices the food and a sliding carriage on bars, placed under the above mentioned
base, which in turn supports the food plate, parallel to the cutting edge of the blade.
The food plate also has an appropriate self-stopping device to keep the product in its proper place
during cutting operations (food press).
The thickness of the slice is regulated by a thickness plate behind the blade; this plate, on which the
food is placed, can be moved transversally to the blade at the thickness of the desired slice.
All the components of the machine are made of a light aluminum alloy and magnesium Peraluman 3,
polished and anodized, in stainless steel and plastic for food products as according to the sanitary
regulations in force so the structure is sturdy, reliable, easy to clean and does not alter in time.
The cutting blade is operated by a self-ventilated motor, under the base; the motor transmission is
obtained with gears, guaranteeing a quiet running. The transmission gear is the top in terms of
reliability, strong efforts, and it is able to cut the product even harder.
Starting and stopping is carried out by using the two buttons at the front of the machine which are
easily identifiable by their color and position; there is a light which indicates the machine is running.
This command system prevents accidental starting of the machine after a possible electric circuit
interruption; this means the slicing machine can only be re-started intentionally.
The machine has a sharpener which is extremely easy and safe to use.
Slice deflector, sharpener and blade cover can be removed for cleaning.
4.3.1 Safety
The mechanical safety devices are the following:
•Irremovable safety ring around the blade (blade protection);
•Food plate which can only be tilted if the index knob of the thickness plate is in the ‘zero’
position and the carriage is at the end of its position on the operator’s side. Once the arm
complete with food plate has been tilted the thickness plate is locked in the above mentioned
position;
•Safety guard on meat table;
The electric safety devices are the following:
•Start-up with start and stop buttons with a low tension control circuit that also requires a
voluntary re-start of the machine in the case of an electric circuit interruption.
4.3.2 Residual risks
WARNING: The safety ring around the blade is made according to the European regulation
(EN 1974:1998) but this protection does not completely eliminate risks in the sharpening
area

Use and maintenance
10
DO NOT use the machine if you are not in perfect psychological and physical conditions and NOT
allow anyone to get close during use.
