SAFETY INSTRUCTIONS.
The safe and systematic use of the mixer is subordinated to compliance with behaviour and standards listed
hereafter.
Safety standards
Personnel must be in good physical and mental conditions and be adequately instructed on the use
of the mixer having read this publication.
The safety manager of the company, of the operating area and of the department, when choosing
the person who must use this equipment (a person suitable for the job according to Standards in
force), must consider his/her cultural preparation, physical suitability and the psychological aspect
(mental stability, sense of responsibility, etc.). Moreover, based on the attitudes and capacity that
were verified, the manager must provide this person with proper training, having him/her read the
present publication, in order to have full knowledge of the mixer and of the rules of behaviour
applying to it.
The area around the mixer must be well lit, free from other objects and clean.
The personnel in charge of running, cleaning and carrying out maintenance on the mixer must wear
the required PPE (personal protective equipment).
Do not wear dangling clothing or fluttering hems (ties, napkins, torn suits, open jackets etc.) to avoid
getting entangled.
During maintenance and cleaning, the operator must disarm the master switch and place the system
in safe conditions (for example, removing the plug).
Never leave the mixer unattended while it is running. Be careful of abnormal noises or behaviour.
Keep away from rotating parts. Never open the grid before the equipment has come to a complete
stop.
At the end of work, empty the machine completely, disconnect the master switch cutting the power,
place it in safe conditions and clean it with a neutral degreasing agent (i.e. with Marseille soap).
Safety devices.
The mixer is equipped with some devices which protect its operation as well as the safety of the operator.
They must not be removed or modified. Their functioning must be checked periodically.
Master switch: cuts power from the mixer, for maintenance in safe conditions.
Circuit breaker switch: cuts power if the electric motor overheats.
Fixed guards: All casings and guards fixed with screws or mechanical locks can be removed only for
maintenance, by specialised personnel and in the prescribed modalities. When the work is over, they
must be mounted immediately.
Mobile guards: Movement of the grid activates a micro switch which prevents the mixer from running
if the grid is open. If the grid is lifted while the mixer is running, it stops the cycle unconditionally, just
like an emergency stop. The start button must be pressed for the mixer to restart.
Safety Standards applied to the mixer.
EN 292 Safety of machinery.
EN 294 Minimum distances to prevent accidental contact.
CEI 17-13. Low-voltage switchgear and control gear assemblies.

RESIDUAL RISKS
Danger for limbs: Going beyond the protective grid or removing the casing during maintenance, it is
possible to access the moving organs of the mixer.
They are dangerous areas where serious physical injuries can occur. Do not introduce limbs or other
objects without having placed the mixer in safe conditions.
Danger of electrocution: the mixer must not operate without an adequate earthing system. It must be
connected to a system built in compliance with construction standards in force in the country where it
is installed.
Automatic cycle: after starting up the mixer, it follows an automatic operating cycle. Never go past
the safety barriers with your limbs or other objects while it is running.

USE AND DESCRIPTION OF THE MIXER:
The mixers of the SILVER series are designed to amalgamate food mixtures which use water and flour as
their main ingredients. A spiral rotates mixing, amalgamating, refining and oxygenating the mixture in the
rotary bowl and, thanks to the mechanical action of the system, the mix is quickly and efficiently prepared.
Conceived to make dough for bread, the mixer is suitable for all types of leavened mixtures and products to
be baked, made from the following ingredients: all types of flour, water, yeast, grease - butter, sugar, aromas
and colourings allowed by law, salt, Liqueurs, and other ingredients for making bread and pastry.
Adapting the mixer to other work processes would implicate not only modifying the machinery by authorised
personnel but also the amendment of this manual.
The high-power motor, the transmission system and the steel framework make it sturdy and reliable, with a
large size suitable for professional use. The safety devices and electrical control equipment complying with
European Standards complete the machinery.
The mixer, loaded with the ingredients, usually water, flour and additives in the order and maximum amounts
described further down, is started from the controls panel and performs a manual or times cycle of a few
minutes where the spiral rotates together with the bowl, amalgamating the ingredients. In order to remove
the mixture, turn off the mixer by switching off the master switch, lift the grid and remove it from the bowl by
hand. Use a plastic, aluminium or wooden spatula (which do not scratch the bowl) to make the operation
easier.
CONDITIONS FOR USE:
Atmospheric conditions: The mixer needs to be installed inside of a lit, ventilated building, on top of a solid
and level support. Temperatures from 5 to 40°C with humidity no greater than 90%.
Lighting: the light at disposal of the operator must comply with the type of work carried out, in relation to
general lighting, according to the Standards in force. It must on any account be sufficient to read the controls
and danger signs and must not blind the operator.
Vibrations: in correct working conditions, vibrations do not create dangerous situations.
Noise emissions: 70 dbA for normal use.
Electromagnetic environment: the machine has been built to work correctly in an industrial type of
electromagnetic environment.
Environments with risk of explosion: An atmosphere capable to being transformed into an
explosive atmosphere due to room and/or operating conditions is defined a potentially explosive
atmosphere.
The mixer was not built to work in environments with potentially explosive atmospheres.
IDENTIFICATION, POSITION OF THE OPERATOR AND DANGEROUS AREAS.
There is a plate on the back of the mixer like the one shown which carries indications concerning the
manufacturer, the type of machine, serial number, electrical features, frequency, absorbed power and the
number of phases and the year of construction. The figure at the side shows the position of the plate, that of
the operator respect to the mixer and
the AS danger area which must be
free from people for a distance A =
400 mm.

SL-50 SL-60 MIXERS 8 of 23
STORAGE:
Storage of packed mixer:
The mixer must be stored in a closed and covered place, on a smooth and solid surface protected from dust
and filth, sheltered from atmospheric agents and hygienically safe.
The temperatures must remain between –20 and +50°C, and humidity no greater than 90%.
Storage of unpacked mixer.
If the mixer has already been unpacked, in addition to that above, it must be lifted from the ground with a
pallet or other and covered in order to protect it from humidity, dust and filth. If wrapped in cellophane or
another type of plastic, avoid airtight closing below the mixer in order to prevent corrosion linked to
condensate.
ATTENTION! The mixer must not be stored in the open!!
INSTALLATION
The mixer must stand in a vertical position, on a smooth surface sufficiently sturdy for the load (floor
with resistance over 20 km/cm2). If in danger of tipping over (assembly on ship or other), anchor the
mixer to the floor using 4 plugs or bolts with a traction resistance over kg 400 (M10) using the
appropriate anchoring devices supplied upon request.
ATTENTION.
Do not make the mixer function only on wheels, always tighten the two supports “A” until the wheels are fully
lifted.
Connection to electrical mains
The electrical connection must be carried out by a specialised electrician, according to the modalities
and standards in force in the country where it is installed. Make sure that the voltage and frequency
of the system are the same as those on the mixer identification plate. Incorrect connection makes
the warranty void.
PRESERVATION OF THE MACHINE
Storage before a long period out of service
Clean the mixer thoroughly.
Disconnect it from the electrical mains.
If possible, put it back into its original packing.
WARRANTY TERMS
Validity: The warranty starts from the delivery date and lasts 12 months, if:
The mixer was not damaged during transportation, and it was installed, commissioned, used and
serviced as prescribed in this manual.
It was not tampered with, modified and no unintended tools were installed on it.
It did not undergo modifications or repairs carried out by the customer or third parties in an
incompliant fashion or without the prior consent of the supplier.
The following conditions constitute improper use of the mixer:
•Loading more than what is allowed or use of unsuitable ingredients.
•Cleaning with unsuitable tools or instruments that can scratch the bowl or damage the mixer or paint.
•Use of the mixer in unsuitable places.

SL-50 SL-60 MIXERS 9 of 23
Modality for granting the warranty
If the customer finds defects in the mixer, he must immediately inform the supplier, who will carry out a quick
analysis of the lack of compliance and will establish the intervention mode with the customer.
The customer must provide the needed time and opportunity to carry out modifications, improvements,
repairs or the supply of spare parts which the supplier deems reasonably necessary. If this does not occur,
the supplier will not be held liable.
Parts subject to wear
Some components are scaled for a life duration far longer than that of normal mixer use during the time of its
warranty. Breakage or malfunctioning of these pieces depends on their use. They are therefore considered
parts subject to wear and are not included in the warranty, unless they manifest evident defects in the parts
or machinery.
The parts subject to wear are: transmission belts, motors, bearings and bowl.
INSTRUCTIONS FOR USE.
The mixer is provided with a master switch on the right side. It is controlled by one of the front
panels shown below.
The first panel has a manual timer with a selector for inversion of the rotation direction of the bowl and one
for the exclusion of the timers in the event of a failure. There are start and stop switches on the equipment to
start and stop the mixer.
The second and third panel, besides the selector inverting the rotation direction of the bowl and the one
excluding the timers in the event of a failure, also has an electromechanical emergency button which
immediately stops the mixer wherever it is.
The exclusively digital timers are adjusted by pressing the select key and setting the time by means of the +
and - keys. Having set the time of the first speed, press the select key to set the time on the second timer.
When the times have been set, press select once again to confirm the selection and to start work with the
mixer.
ATTENTION: The grid must be down for the mixer to work. Otherwise the safety system will block its
functioning.
Check the correct rotation direction of the bowl (clockwise, according to the arrow). If incorrect,
contact a qualified electrician.

PROCESSING WITH THE MIXER.
The mixer is now ready to mix. Follow some simple rules:
Firstly pour the required amount of water into the bowl.
Add the correct amount of flour, so that the mix hardens gradually to the right consistency.
On the contrary, adding water to flour creates lumps of flour on the base that must be worked
longer with consequent damaging of the mix.
The other ingredients (salt, yeast, oil, etc.) are added at will.
The spiral mixer is a machine where the work load is established by the customer. Despite all the information
regarding using the spiral mixers, many problems arise due to them being submitted to improper use. The
limit of use of the mixer is reached not by exceeding on the amount of the pasta, limited by the volume of the
bowl, but by the too low percentage of water.
A first but valid indication is supplied by the following table:
MODEL. PASTA kg FLOUR kg WATER % WATER litres
Silver 50 45 19-20 55 / 60 % 25-26
The use of flours rich in gluten creates very doughy mixes which absorb a lot of power. In this case, as well
as in the case of mix with percentages of water below those indicated in the table, it is necessary to reduce
the maximum mix capacity of the mixer.

CLEANING AND MAINTENANCE OPERATIONS.
DO NOT CARRY OUT ANY MAINTENANCE OR CLEANING WITH ELECTRICITY
CONNECTED
The mixer does not require particular maintenance operations. All bearings and
transmission parts are lubricated for life. Keep the mixer clean to avoid flour from
depositing in the moving organs thus generating bothersome creaking and abnormal
wear.
To tension the belt,
remove the upper
casings, loosen the
motor bolts and act on
the appropriate register.
Fasten the motor bolts,
place the casings back
and test the machine.
Anomalies of the grid
micro: remove the
upper protection
casing, intervene on
the micro, close the
casing again and test
the machine.

SPARE PARTS
SIGMA S.r.l. reserves the right to carry out all the modifications that it deems necessary for its mixer
models. It is therefore always necessary to specify:
•Type of mixer
•Serial number
•Year of construction
•Position, description, item code and desired amount of pieces requested.
Send the request to:
MAIN COMPONENTS:
•Raw materials used: almost all of the components of the mixer are made of steel, cast iron, brass
and plastic. All of these components can be disposed of easily and do not represent a danger for
environmental pollution and/or personal safety. Separate the different materials for subsequent
reuse or differentiated waste collection.
•The electrical system must be dismantled and disposed of through a specialised company.
•Treatment of surfaces: painting of metallic surfaces with products compatible for food use.
•Sigma packaging replies fully with that required by Directive 94/62/EC and by Legislative Decree
05/02/97 n. 22 (and subsequent amendments and integrations). They thus can easily be assimilated
with city waste and can be inserted in any public differentiated waste program.
DISMANTLING AND WASTE DISPOSAL:
The purchaser is responsible for putting the mixer out of service, who must comply with local standards and
regulations. Dismantling of mechanical and electrical parts must be entrusted to competent personnel.
