1.1 Foreword
1.2 Warranty: terms and conditions
The machine is covered by warranty for a period of twelve months from the
date of delivery, the warranty being limited to parts with manufacturing
defects and excluding the motors and electrical system.
Furthermore, any parts damaged during transport, as a result of poor or
incorrect installation or maintenance or because of negligence or improper
use are not covered by the warranty.
The warranty is valid for the original purchaser only and does not, under any
circumstances, include the replacement of the machine. The warranty is
invalidated if the machine is tampered with or subject to alterations or
repairs by personnel not authorised by C.M. SOTTORIVA S.p.A..
The manufacturer is not liable for any injury to persons or animals or
damage to objects caused, either directly or indirectly, by machine
breakdowns or as a result of not being able to use the machine. Defective
parts are normally repaired or replaced on the customer's premises, with the
travel, board and lodging expenses for the personnel sent to effect the
repairs or replacements being charged to the customer. The travelling time
and hours worked by the personnel are also charged to the customer; the
hourly rate will be calculated in accordance with the Anima tables.
If, according to the unquestionable judgement of the engineers, the work
cannot be performed on the customer's premises, then the customer must
have the machine delivered free of carriage to C.M. SOTTORIVA S.p.A.
After the repairs have been effected free of charge, the customer must then
have the machine delivered back to his/her premises, carriage paid. If any
repair work is performed after the expiry of the aforementioned warranty
period, the customer will be charged for labour (in accordance with the
Anima table), travel and board and lodging expenses, the cost of the
replaced parts and any transportation costs for the replaced parts. The rates
will be calculated in accordance with the Anima table in the possession of

3. Operation and installation
manual
3.1 Foreword
In compliance with European Community Directive no. 98/37/EEC, and for
the purposes of this manual, the following definitions are used:
1)
"Danger area"
, any area inside or near a machine which might be
dangerous for a bystander.
2)
"Bystander"
, any person entirely or partly situated in a danger area.
3)
"Operator"
, the person or persons installing, running, adjusting,
cleaning, repairing, transporting or performing maintenance work on a

3.3 Hoisting and transportation
To move the machine, it must be lifted as follows:
-
thread a lifting cable under the head, where the head meets the column, as
shown in
Fig. 4
on page 14
and secure as shown in
Fig. 4
to a hoisting
mechanism (crane, bridge crane, hoist, etc.). Place felt cloth between the
hoisting cable and the part of the machine under the head. Place a wood
shim of 70-80 mm thickness betweeen the side of the machine head and
the hoiting cable in order not to damage the paint finish or structure; lift the
machine gradually without any abrupt pulls.
Raising and lowering the machine must be a gradual process to avoid the
build up of kinetic energy which the braking system could not over-ride.
Given the considerable mass of the machine, before pushing it on its wheel
mounts, make sure no-one is standing behind or near the machine, since
impact could cause serious injury.
Fig. 4
Caution!
Before lifting the machine make sure that the cables are strong
enough to bear the load, and thatthe hoisting device has the suitable
capacityon the basis of the arrangementof the cables. In all cases,
equipment used for lifting must comply with current laws and regu-
lations.

3.4 Assembly and installation
3.4.1
Installation precautions
The machine should be placed on the ground at the point shown in par. 3.3.
The machine must be lowered onto its supporting platform as gently as
possible in order to avoid damaging either the machine itself or the floor.
The machine should be moved on its wheels by pushing it to the new site
(see precautions above). When the machine is properly located, secure the
legs to the ground
ref. 9
Photo 1
on page 8
by using the knobs
ref. 7
Photo 1
to avoid excessive movements during the kneading process.
3.4.2
Instructions for the electrician
The electrician carrying out the installation must be skilled in this type of
work, properly trained and fully informed of the technical contents and
norms relating to the work, and of the standards of good practice.
The machine must be connected to the bakery's electrical plant in full
compliance with currents norms and regulations on the basis of the machine
specifications given in this manual; the machine is supplied with a CEI20-22
lead and EEC type plug (with the number of poles specified on the machine
plate) for connection to the electricity supply. Use the earth connection
system properly, without running the earth wire along gas or water pipes or
other metal structures not intended for earthing.
The power supply lead must be kept well clear of heated or moving parts.
The cable must not interfere with the movement of people or objects inside
the bakery.
3.5 Start-up
Trained personnel are not required to start up or operate the machine
(whereas properly trained personnel are required for some maintenance
operations; see para
4.1
), although all personnel starting up and operating
the machine must have read this manual from cover to cover and thoroughly
understood its contents.
Caution
Make sure that the mains voltage is the same as the voltage clearly
marked on the machine plate par. 2.3).

After placing and securing the machine in its final location, carry out the
following important control operations in the given sequence:
1) check the mains voltage against the voltage shown on the machine plate
(seepar. 2.3)correspondstothelaboratoryvoltage;ifthevoltageisincorrect,
do not make electrical connections under any circumstances. Contact the
supplier or manufacturer immediately.
2) Make sure the machine rotates in the right direction; to do this, after
plugging in, carry out the following procedures:
-
switch the main switch
ref. 8
Photo 1
on page 8 to position 1;
-
set the minimum time on the timer
ref. 7
Fig. 1
on page 8;
-
press the start button for the 1st speed
ref. 1
Fig. 1
;
From the front of the machine, as shown in
Photo 2
on page 10
, the spiral
tool must rotate clockwise.
If this is not the case switch off, using the pushbutton
ref. 3
Fig. 1
; then switch
the main switch
ref. 8
Photo 1
from position 1 to position 0, unplug, unscrew
the plug as shown in the figure and invert the black and brown wires.
If the connection is three-phase + neutral + earth, there are two black wires.
In this case, either black wire may be switched over with the brown wire; if the
cable is three-phase + earth there is only one black wire so there is no
problem in switching over the wires.
Close the plug with the screws, as shown in the above illustration, and plug
back into the mains socket.
Re-check, repeating the sequence given at point 2. of this paragraph.
Rotation should now be clockwise.
Caution!
Never disconnect the yellow-green (earth) and/or blue wires or
change their positions.

should be occupied only for brief moments.
1) Feed into the tank
ref. 2
Photo 1
on page 8
all ingredients to be kneaded,
without exceeding the total mass specified in
Table 2
on page 11.
For this purpose, since the specific weightof flour is much less than water, the
capacity of the tank was designed on the basis of a water/flour ratio of 0.55,
loading the flour first, then the water (causing the flour to gain in density and
lose volume).
2) Switch the main switch
ref. 8

to position 1; the warning light
ref. 5
Fig. 1
on page 8 will come on;
3) Lower the accident-prevention guard
ref. 3

if raised, since in the
raised position the machine will not start).
4) Set timers
ref. 7 and 8
Fig. 1
torequiredkneadingtimesforslow and quick
blending.
5) Press the pushbutton
ref. 1
Fig. 1
for low speed start-up leaving the tool
enough time to "bind" the ingredients.
6) At the same time, switch the switch
ref. 4
Fig. 1
to the right-hand position
to rotate the tank clockwise, or to the left-hand position to rotate the tank
anticlockwise; the movement can be inverted or stopped (switch position 0)
at any time.
After the set time
ref. 7
Fig. 1
, the machine will automartically switch to the
fast cycle, for the set time
ref. 8

.
Caution!
At the beginning of kneading operations, before the flour has absor-
bed much water and is still in the form of a powder, it is sensible prac-
tice to use the kneading tool at slow speed for 2 minutes to prevent
flour becoming air-borne and getting into the lungs, which, after len-
gthy periods of exposure, is dangerous for the health.

7) Press the pushbutton
ref. 2
Fig. 1
to start up the machine directly at the
fast speed (this should not be done if there is still unmixed flour in the tank,
as specified above) or to skip from slow to fast speed at any moment.
8) When the set times for the two cycles have been reached, the tool
automatically shuts down.
9) Activating any of the safety devices or pressing the emergency stop
ref. 6
Fig. 1
, (or by means of the accident-prevention guard
ref. 3
Photo 1
on page
8), moving parts come to a stand still very quickly.
To prevent wear to the electrical emergency devices,
do not use emergency
shut-downs if it is possible to switch off normally
ref. 3
Fig. 1
.
Emergency devices should be used only to prevent dangerous situations
from arising or in dangerous situations (i.e. only in emergencies).
Remove the kneaded materials from the tank manually, in large provisional
portions, using a plastic paddle arm (never use steel paddles or scrapers).
10) Refill the tank with ingredients for the next operation.
