The foundation
Our company was founded in 1963 by the Lorenzo, Luigi and
Paolo Cuppone brothers. It immediately specialized in the pro-
duction of ovens and equipment to prepare and cook pizza.
The constant research and experimentation of new equip-
ment that are even now the strength of our company, have led
us to design and patent the machinery and ovens that have
revolutionized the way pizza is made.

Knowing the appliance
This appliance has been designed and built for food use only,
for the cold processing of cereal flour-based doughs; its main
use is therefore in pizzerias, bakeries and pastry shops.
The purpose of the machine is to round portions of already
portioned dough to the desired weight, while maintaining the
basic characteristics of the dough unaltered; the action carried
out by the screw determines the advancement of the dough
and the consequent compression of the same against the
ribbed surface of the cylinder from which, once it comes out, it
will be very compact and with good roundness.
Fig. 2
The main parts of the machine are:
1 Auger
2 Tray: accommodates the rounded dough balls
3 Cylinder
4 Emergency STOP button
Pressing the red STOP button switches off the machine
and stops the rotary movement of the cylinder.
It must therefore be used only when really necessary and
not as an ON/OFF switch to be used at the end of the work
day.
If pressed, to restore the conditions of use, unlock the
button by turning it clockwise.
5 Control panel - ON/OFF keys
- black button 0: machine stop
- white button I: machine start
- central light: if on, it indicates that the machine is on.
6 Wheel with brake: during normal use, always keep the
appliance blocked by lowering the brakes of the front
wheels.

Use
Using the appliance
Fig. 3
Turn on the machine by pressing the I button “5A” located on the control panel; after
pressing the white light “5B” comes on and the cylinder rotates.
If the machine does not turn on, check if emergency STOP button “4” has
been pressed; if so, unlock it by turning it clockwise.

1
Using a spatula, portion the dough, checking with a scale that the weight of the
pieces made is as desired.
Always comply with these instructions:
Model Portion weight Dough
hydration
Minimum Maximum
RND280 20 g [0.044 lb / 0.70 ounces] 300 gr [0.66 lb / 10.58 ounces] from 50% to 65%
RND800 20 g [0.044 lb / 0.70 ounces] 900 gr [1.9 lb / 31.7 ounces] from 50% to 65%
If you use doughs with higher hydration (up to 70% maximum), to obtain good
results we recommend you use the dough at 10°C (50°F).
2
Insert the portions created inside the auger, without ouring them. It is possible
to insert all the portions provided in succession, without having to wait for the first
formed balls to come out. To ensure the indicated hourly productivity (900 balls/hour)
it is necessary to insert the portions inside the auger every 4 seconds.
3
After a short time from insertion, perfectly rounded balls of dough will begin to be arranged on the tray.
4
Arrange the balls in the special box with the protuberance facing down.

Problems during use
During use, some problems may occur that can be easily solved following the instructions detailed below.
PROBLEM ENCOUNTERED PROBABLE CAUSES SOLUTIONS FOR THE USER
The dough balls stick to the auger and find it
difficult to get back up The dough is too hydrated Use doughs with hydration from 50 to 65%. If you use doughs with higher hydration (up to 70% maximum), to obtain good results we recommend you use the dough at 10°C (50°F).
Dough balls do not stick to the auger but
find it difficult to get back up
The dough is not very hydrated Use doughs with hydration from 50 to 65%. If you use doughs with higher hydration (up to
70% maximum), to obtain good results we recommend you use the dough at 10°C (50°F).
The dough was left in the air for a long time and
dried up Once the dough is portioned, start rolling quickly
The portion of dough that goes into the auger
is too large Comply with the indications given in the table on page 7
The portions of dough were floured before being
inserted into the auger Do not flour the dough portions
The rounded ball is much larger than the
amount of dough inserted
The portions of dough were inserted too quickly
one after the other inside the auger and joined
together
Increase the time between inserting one portion of dough and the next
After pressing the ON/OFF button, the
machine does not start
The appliance has been stopped pressing the
emergency button
To reset the normal operating conditions, unlock the emergency button rotating it clockwise
and restart the machine with the ON/OFF button
The machine is not powered Make sure that the plug is correctly inserted into the socket and that there are no interruptions
to the electricity supply (e.g. black-out)

Warnings
Before carrying out any cleaning operations, it is neces-
sary to disconnect the power supply of the appliance
(using the system switch), wear suitable personal pro-
tection equipment (e.g. gloves, etc.). The user must carry out
only routine maintenance, for extraordinary maintenance, con-
tact a Service Centre requesting service from an authorised
technician. The Manufacturer warranty does not cover damages
due to negligent or incorrect maintenance or cleaning (e.g. use
of unsuitable detergents).
When cleaning any part or accessory do NOT use:
• abrasive or powder detergents;
• aggressive or corrosive detergents (e.g. hydrochloric
or sulphuric acid, caustic soda, etc,). Caution! Never use these
substances also when cleaning the substructure/floor under
the appliance or its base;
• abrasive or sharp tools (e.g. abrasive sponges, scrapers, steel
brushes, etc.);
• steamed or pressurised water jets.
It is best to have an authorized service centre perform
maintenance and inspection on the appliance at least
once a year to ensure top working and safety conditions.
Cleaning the appliance
Cleaning the external steel parts
Fig. 5
Use a cloth soaked in hot soapy water and finish with a thor-
ough rinsing and drying, taking care to remove all traces of
detergent.
Cleaning the control panel and emergency button
Clean the control panel and emergency button with a soft
cloth and a little detergent for delicate surfaces. Avoid using
considerable quantities of product since any infiltration may
seriously damage the controls. Avoid also using very aggressive
detergents that may damage the material the display is made
of (polycarbonate).
Cleaning the wheels
Clean the wheels with a soft cloth and a little detergent for
delicate surfaces. Avoid also using very aggressive detergents
that may damage the material the wheels are made of.
