1. Introduction
1.1 Foreword
1.2 Guarantee: validity and therms
The machine is covered by six months guarantee from the date of delivery
limited to any parts that show manufacturing defects with the exception of
the electrical plant.
The guarantee is not applicable to parts of the machine that have been
damaged during transport, due to poor or incorrect installation or main-
tenance, and due to negligence or unskilled use.
The guarantee holdsvalid only for the original purchaser of the machine and
shall not envisage the complete replacement of the machine under any
circumstances. The guarantee shall be null and void if the machine has
been tampered with, modified or repaired by personnel who have not been
previously authorised by C.M. SOTTORIVA S.p.A.
The Manufacturer shall not be held liable for possible direct or indirect
damage or injury to animals, persons or property caused by malfunctions of
the machine or any damages resulting from the failure of the machine to
operate. The repair or replacement of defective parts of the machine is
normally carried out on the client’s premises and is therefore subject to
charges for travel, board and accommodation for the personnel sent to carry
out the work. The client will also be charged for travelling time and working
hours of the relative personnel, in accordance with the A.n.i.m.a. (Italian
association of food machinery manufacturers) scale. If, at the final decision
of C.M. SOTTORIVA S.p.A. technical personnel, it is impossible to carry out
the work at the client’s premises, the client is required to ship the machine
carriage paid to C.M. SOTTORIVA S.p.A. and, after having carried out the
repairs and maintenance work free of charge, C.M. SOTTORIVA S.p.A. will
ship the machine to the client carriage forward.
When the foregoing guarantee period has elapsed, repair and maintenance
will be carried out and labour costs (according to A.n.i.m.a. scale) travel,
board and accommodation, the cost of the replacement parts and any
relative transport costs will be borne by the client.
Labour rates in accordance with the A.n.i.m.a. scale will be in the
possession of the technical personnel that perform the work.
For valid guarantee claims, the guarantee certificate (see facsimile below)
must be duly compiled in all its parts and returned within
15 days
of the date
of delivery.
Caution!
Before starting the machine
read carefully the instructions in this
handbook and adhere strictly to the recommendations contained
herein.
CONSERVE this handbook and all attached documentation in a
place that is accessible and known to all operators and maintenance
personnel; the handbook must be kept in a dry place, preferably in
an envelope to protect it against dust, damp, light, etc.

2. Descriptive manual
2.1 Foreword
The machine shown in photo 1 and described in this handbook is designed
for use in bakeries and confectionaries for the production of round forms of
dough for special bakery and/or confectioner’s products whose basic
components are wheat flour and water.
Any attempt to employ the machine for other uses is potentially dangerous
for the mechanical devices on the machine and hence for the operator.
The positions normally occupied by the operator are shown below and
marked Lp. These are also the reference positions for noise testing
(see par.
5.5
).
2.2 Description
The machine (see
Photo 1
) is fitted with a hopper
ref. 1
Photo 1
into which
to load the dough to be divided.
A piston type dividing system located beneath the hopper approximately in
the area indicated by
ref. 2
divides the dough into pieces of a set weight.
The pieces are conveyed out by means of a conveyor belt
ref. 3
Photo 1
which can be of two different lengths.
The electrical panel
ref. 4
Photo 1
is located below the infeed belt.

A flour unit
ref. 5
Photo 1
is located above the outfeed belt and can be
switched on or off when the machine is running by means of a lever switch
positioned on the unit itself.
The quantityof flour per unit time delivered onto the belt, and hence onto the
product, can be adjusted with the knob on the front of the flour unit.
The long version of the outfeed belt can be folded back on itself when the
machine is at rest simply by lifting it with one hand, in order to reduce the
overall dimensions of the machine.
Finally, the version of the machine with geared motor marked “R” can
produce pieces in either 1 or two rows (obtainable product weights change
of course).

3.4 Machine installation
3.4.1
Installation warnings
Position the machine so that the free length of power cable from the
machine to the socket is as short as possible.
3.4.2
Notes for the electrical installation personnel
The electrical installer must be qualified and experienced in carrying out
work of this nature and should therefore be aware of the various technical
notions and applicable standards to guarantee high standards of
workmanship.
Hook-up of the machine to the bakery electrical installation must be carried
out in compliance with the established regulations and prescriptions with
reference to the information and instructions contained in the present
handbook. For this work the machine is supplied with a CEI 20-22 electrical
cable and an EC standard plug with as many poles as indicated on the
machine dataplate. The machine must be connected to a proper and
efficient earthing plant. Do not use makeshift solutions by connecting the
earth to water pipes, gas pipes or other metal structures.
The power feeding cable must be kept well clear of heated surfaces and
moving parts. It must also be installed in such a way that it does not present
an obstruction to the movement of personnel and materials in the bakery.
Caution!
Before lifting the machine, make sure that the lifting ropes and lifting
equipment are of suitable load capacity in relation to the weight of
the machine.
Caution!
When lifting and lowering the machine, the ascent and descent
movements must be as gradual and smooth as possible, avoiding
jerkiness and sudden increases in kinetic energy that are difficult to
withstand when the movement is stopped suddenly.
Caution
!
Make sure that line voltage is the same as the voltage required by the
machine as clearly shown on the machine dataplate (heading 2.4).

3.5 Start up
1) Make sure that the machine voltage shown on the dataplate (see
2.4
) cor-
responds to the line voltage available in the place of installation; if it does
not,donotmaketheelectricalhook-up;contactyour dealeror themachine
manufacturer immediately.
2) Make sure that the motors rotate in the correct direction; to do this, plug
the machine into the power socket, set the main switch to position 1 (the
warning light
ref. 4
Fig. 1
will indicate that the power is on); press the start
button
ref. 2
Fig. 1
, standing by to press the emergency stop pushbutton
ref. 1
Fig. 1
if necessary. The direction of movement of the top of the
outfeed belt
ref. 3
Photo 1
must be outwards from the machine. Ifit moves
in the opposite direction, press pushbutton
ref. 1
Fig. 1
; unplug the
machine, open the plug by unscrewing the screws shown in the figure
below and invert the position of the brown and black wires.
If the connection is three phase + neutral + earth there will be two black
wires. In this case either of the black wires can be inverted with the brown
wire. In the case of a three phase + earth cable there is only one black wire
so there is no alternative for the inversion with the brown wire position.
Close the plug with the screws as shown in the above figure and re-insert it
in the power socket. Repeat the steps described at the beginning of this
heading to make sure that the direction of rotation of the motors is correct.
Once you have checked the direction of rotation, switch the machine off.
Caution
Never disconnect or change the position of the yellow/green wire
(earth) and/or the blue wire(s).
Caution
Tampering with/replacing one or more machine components or
assemblies, and/or the use of accessories/attachments or con-suma-
bles that are different from the parts recommended by the Manufac-
turer can result in potential danger of injury to the machine operator
or exposed persons and will auto-matically relieve the Manufacturer
of any what-soever liability for injury to persons and/or damage to
property that may arise.

Photo 4
, and
the piece size index to set, according to desired piece
size and machine
version, for dividers not equipped with geared motor (if the machine has a
geared motor, simply draw up a table similar to the one below).
Caution
Before performing any manoeuvre, make certain that the mains vol-
tage is the same as the voltage required by the machine and clearly
marked on the identification plate (
2.4
).
Caution
When the pin is lowered, its bottom end must be positioned as shown
in photo 3/B in relation to the bronze protrusion on the geared motor
piston. Do not position it on the other side (as in photo 3/C) as this
would cause serious mechanical damage to the machine.
