4.3 GENERAL DESCRIPTION
The slicing achine has been designed and ade to
offer axi u safety when in use, during cleaning
and ordinary aintenance; axi u hygiene fro
the use of inoxidisable aterials or adequately
protected against oxidisation together with an
attentive design of all the parts that co e into
contact with food; axi u cutting precision and
capacity together with sturdiness and reliability of
the structure.
The achine is essentially ade up of a base that
holds a circular blade that is vertically ounted and
a sliding carriage on bars, parallel to the cutting
edge of the blade, which in turn holds a food plate.
The food plate is ade up of a base plate and an
overplate which slides at right angles to the edge of
the blade for slicing the food; the overplate also has
an appropriate selfstopping device, which can be
regulated in height, to keep the product in its proper
place during cutting operations (food press).
Carriage ove ent and blade rotation are
co pletely anual; by activating rotation of the
flywheel with the special handle the carriage is put
into otion and at the sa e ti e with a chain
trans ission the blade is turned.
The product is cut during the forward ove ent of
the carriage, parallel to the blade; the thickness of
the slice is regulated by a echanical device which
is auto atically started every ti e the carriage
co es back, aking the sliding overplate
transversally towards the blade, with a value which
is pre-deter ined by the graduated handwheel.
All the co ponents of the achine are ade of a
light alu iniu alloy, in stainless steel and plastic
for food products as according to the sanitary
regulations in force.
The achine has a sharpener which is extre ely
easy and safe to use.
The food plate, sharpener, slice deflector and blade
protection can be re oved for cleaning.
4.3.1 Risks during use
DO NOT use the achine if you are not in perfect
psycho-physical condition and DO NOT let anyone
co e near during use; concentrate when loading
and cutting the product.
Pay attention!
Only cut products which are allowed; DO NOT try
cutting products which are forbidden.
DURING CLEANING, LUBRICATION AND BLADE
SHARPENING ALWAYS USE PROTECTIVE GLOVES
WHICH ARE RESISTANT TO CUTS AND TEARS.
