Before purchasing the product and installing it, check the
following conditions, necessary for the correct installation,
operation and maintenance of the product.
A Transport (Owner’s inspection)
√Make sure that, on the day when you receive the prod-
uct or it is installed:
•Fig. 1 lifting equipment is available that can handle
the appliance safely (check weight and dimensions in
the following pages), together with staff qualified to
carry out this operation;
•personal protection equipment is available (e.g. safety
shoes, gloves, etc.)
B Installation room (Owner’s inspection)
√Make sure that:
•the floor of the installation room is fireproof, perfectly
flat and capable of withstanding the weight of the
appliance;
•Fig. 2 the installation room:
• is dedicated and suitable to cooking food;
• has adequate air ventilation;
•complies with the current regulations on health
and safety and systems in the workplace;
• is protected from the weather;
•has a maximum temperature of between +5° (41°F)
and +35°C (104°F);
• has a maximum humidity of 70%.
• the appliance easily passes through doorways;
•Fig. 2 there are NO other sources of heat (i.e. grills,
fryers, etc.), highly flammable substances or fuels
(i.e. gasoline, petrol, bottles of alcohol, etc...) in the
vicinity of the appliance. It is absolutely necessary to
comply with the minimum safety distances between
the product and other flammable equipment or
materials.
•there is adequate ventilation according to the reg-
ulations in force in the Country of installation. If this is
not the case, a ø140 mm [Ø5.51”] air intake is manda-
tory, communicating with the outside or a ventilated
room (i.e. storeroom, attic, garage, basement).
Leave a free space of at least 20 cm between the appliance
and the walls of the room and/or other equipment to facili-
tate the use, cleaning and maintenance of the machine itself.
When choosing the positioning room, take into ac-
count that the appliance must be easy to move for
any extraordinary maintenance: be careful since any
brickwork after installation (e.g.: wall construction, door re-
placement with narrower ones, renovations, etc.) do not
hamper movements.
1CHECKS BEFORE PURCHASING

4
DElectrical connection (qualied electrician’s
inspection)
√For a correct connection during the installation:
•provide a socket connecting to the electrical net-
work near the product.
• single-phase machines have the connection cable
and plug already tted;
•three-phase machines have the power cable
already installed; a plug (not supplied) must be
tted to it of suitable capacity. This operation must
be carried out by qualified personnel.
•check that the systems in the room comply with
the legal provisions in force in the country of
use and meet the specifications on the serial number
plate. For a correct electrical connection, the appli-
ance must:
•be included in an equipotential system in
compliance with the legislation in force. This
connection must be made between the various
devices with the terminal marked with the equi-
potential symbol . The cable must have a
maximum cross-section of 10 mm2(in compliance
with IEC EN 60335-2-42:2003-09) and must be
yellow-green;
•must be grounded to the mains (green-yel-
low wire);
•must be connected to a thermal dierential
switch in compliance with the regulations in force
(0.03A A type);
•must be connected to an omnipolar circuit
breaker allowing complete disconnection in
overvoltage III category conditions.

2TECHNICAL DATA
Knowing the appliance
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. 3
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.

Problems during use
During use, some problems may occur that can be easily solved following the instructions detailed below.
PROBLEM FOUND 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%.
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%.
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 following instructions:
Model Portion weight Dough hydration
Minimum Maximum
LLKBR280 20 g [0.044 lb / 0.70 ounces] 300 gr [0.66 lb / 10.58 ounces] from 50% to 65%
LLKBR800 20 g [0.044 lb / 0.70 ounces] 900 gr [1.9 lb / 31.7 ounces] from 50% to 65%
The portions of dough were floured before
being inserted into the auger Do not flour the dough portions
The lower disk under the auger
must be cleaned Remove and clean it
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
The surface of the ball formed is not
smooth and has imperfections
The dough did not rest long enough before
portioning Increase the resting time of the dough before portioning it
The dough is too hydrated Use doughs with hydration from 50 to 65% or, alternatively, cool the dough to about 10°C (50°F)
before inserting it into the auger of the rounding machine
The leavening of the dough, made in the refri-
gerator, took place before the balls were formed
(rising/mass leavening).
Use doughs with hydration from 50 to 65%. Leavening in the refrigerator must take place after
forming the balls.
After pressing the ON/OFF button, the ma-
chine 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)
