3. Warranty conditions
3.1. Validity
The warranty becomes effective from the date of shipment and lasts for twelve months, if:
• The machine 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 has not been modified or repaired by the purchaser or by third parties in an inconsistent manner or without
the prior consent of the supplier.
The following conditions constitute improper use of the machine:
• 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 machine, paint and
plastic parts.
• Use of the machine in unsuitable places.
3.2. Warranty mode of provision
The purchaser must immediately notify the supplier of any detected machine defects; the supplier will quickly
analyse the non-conformity and decide, in collaboration with the purchaser, on the actions to be taken.
After agreement with the supplier, the purchaser must give the same the necessary time and opportunity to carry
out any changes, improvements, repairs or supply of under-warranty parts it deems necessary, otherwise the
supplier is exempt from property vices.
3.3. Wear parts
Some components are sized to last longer than normal use of the machine under warranty time. The failure or
malfunction of these parts depends on the use, they are therefore considered wear parts and are not covered by
warranty, except for evident defects on the part or machinery.

the mixer by reading this document.
• Only professional use of the machine is allowed in places where access to the public, to profane, to children
and to anyone not expressly authorised is forbidden.
• It is forbidden to use the machine: for operations and / or with different product(s) to those specified; if the
connections to the service facilities from the site are not run as expected in this manual; in places with risk of
fire and / or explosion and major incidents, high humidity or wet, excess water vapour, oily vapour, dust,
presence of corrosive substances / gases, adverse weather conditions; in the vicinity of naked flame, zones
with projection of sparks and heat sources; in conditions of abnormal vibration or shock.
• The safety officer, and / or the employer, and / or the owner of the company, in choosing the person who will be
authorised to use the machine (suitable person to work according to applicable laws), must check the same on
the basis of attitudes and skills encountered and provide training of the same, with the reading of this
publication, in order to provide comprehensive knowledge of the machine and of the rules of conduct applicable
to it.
• The space around the machine must be well-lit, uncluttered and clean. Leave about 250mm of free space
around the machine, especially on the side where the master switch is located, leave 1000mm.
• Personnel in charge of running, cleaning and servicing the machine must wear the prescribed P.P.E. (personal
protective equipment): gloves, shoes with reinforced tip, goggles, masks and helmet.
Instructions, use and maintenance manual Pag. 8/48 TAURO 35-35PLUS-40-40PLUS
• Do not wear loose clothing or with fluttering hems (ties, torn clothes, open jackets, etc.) to avoid the risk of
entanglement.
• During maintenance and cleaning operations, the operator must release the master switch (OFF) and secure
the system (for example, by removing the plug and leaving it in a clearly visible position).
• Never leave the machine unattended during operation, pay attention to unusual sounds or behaviour and keep
away from rotating parts. Never open the guard unless the tool has completely stopped.
• In order to empty the machine completely, release the master switch (OFF), disconnect power by removing the

6. Safe work methods and procedures
In order to prevent hazardous conditions and/or possible injuries caused by: electric current, mechanical parts, fire,
or of hygienic nature, the following safety warnings must be observed:
• Keep your work station tidy. Clutter can cause accidents.
• Assess the environmental conditions. Do not use or leave the machine in a wet, damp or poorly lit environment,
or in the vicinity of flammable liquids or gases.
• Keep children and unauthorised personnel away. Do not allow these people to approach the machines or work
station.
• Use the machine within its operating range and for the purpose for which it was designed. It works best and at
its safest when it is not overloaded.
• Wear appropriate clothing. Do not wear dangling clothes or accessories that may get entangled in moving
parts. Use the shoes with reinforced tip and non-slip sole. For health and safety reasons, long hair should be
gathered in the appropriate net and gloves should be worn.
• Protect the power supply cable. Do not pull the cable to disconnect the plug. Do not expose the cable to high
temperatures, in contact with sharp edges, water or solvents.
• Avoid unsafe positions. Find the most suitable position that ensures absolute stability.
• Always exercise extreme caution.
• Always take the plug out of the socket after use and before cleaning and maintenance and before moving the
machine, and leave it in a clearly visible place.
• Never use extension cables outdoors.
• Make sure that the machine is not damaged. Carefully check the effectiveness of the safety devices before
using the machine. Make sure that: the mobile parts are locked in place, there are no damaged components,
all the parts have been assembled correctly and the machine can be run normally in optimal conditions. (See
chapter 14)
• Entrust repairs to qualified personnel. Repairs must only be performed by qualified personnel using original
spare parts.
FAILURE TO OBSERVE THESE REQUIREMENTS MAY BE CAUSE OF HAZARD FOR THE USER.
6.1. Risks for the operator
Gripping and dragging hazard: it is present between bowl and structure, between bowl and
contrast wheels
Electrocution hazard: the machine must not be used without adequate earthing, and it must be
connected to a system built according to building regulations in force in the country of installation.
READ THESE INSTRUCTIONS CAREFULLY BEFORE USING THE MACHINE
Instructions, use and maintenance manual Pag. 12/48
TAURO 35-35PLUS-40-40PLUS
Earthing obligation Prohibition to clean and
lubricate moving parts
Prohibition to remove the
safety devices and guards
ATTENTION!
Wear the provided PPE during operation (e.g. shoes with reinforced tip, gloves,
goggles and masks).
Clean the machine thoroughly after use.
Do not remove the safety devices or protective casings.
Do not put any objects through the bowl guard with the parts in motion.
Before any manoeuvre wait for the machine to completely stop, turn it off and
disconnect it from the mains.
Instructions, use and maintenance manual Pag. 13/48
TAURO 35-35PLUS-40-40PLUS
6.2. Residual risks
In short, the residual risks are:
-Gripping and dragging risk (very low) between bowl and base: despite the distance between the bowl and
base meets the UnI EN 453 requirements, there is still a residual risk of being caught and dragged if a person
inserts a body part in this space. The risk is even greater, the greater the thrust with which the person forces the
passage (e.g. of an upper limb);
-Risk (very low) of crushing, shearing, dragging, impact in case of contact with the moving spiral: the bowl
guard meets the requirements of UNI EN 453, however there is the remote possibility that a person reaches the
moving spiral through the gap between guard and bowl, which forms by lifting the guard before the safety
microswitch trips commanding the emergency stop or, once the guard is open, before the spiral completely stops
(maximum stopping time allowed by Standard UNI EN453 is 4 seconds);
-Risk (very low) of bruising by dragging when the bowl is made to turn with guard open via the hold-down
control device: if the operator places his hand in the dough near the spiral and/or column, as the dough rotates it
may drag the hand and push it against the parts with risk of a slight bruising;
-Health risk from inhaling flour powder which, despite the measures taken in accordance with UNI EN 453,
inevitably develops even if minimally, and due to inadequate cleaning of the machine;
-Risk of muscle - skeletal injury: due to ergonomic factors and/or abnormal stresses during the manual lifting of
bags of flours and/or buckets of water to be poured into the bowl, and during the dough extraction operations.
As far as possible and relevant, adequate safety signs have been affixed on the machine; the affixed signs and
their position on the machine are described in the instruction manual.

MACHINE DESCRIPTION AND USE:
MACHINE DESCRIPTION AND USE:
The TAURO mixing machines are designed for professional use only, to mix water and flour-based food dough for
bread-making and pastry workshops. A spiral rotates mixing, refining and oxygenating the mix contained in a rotary
bowl and, thanks to the vigorous mechanical action performed by the system, the mix is quickly and effectively
prepared.
As specified above, the machines are for professional use only, by educated, trained and authorised personnel.
Any other use is forbidden, any particular needs and specifications must be examined by the SELLER on request.
The machine, filled with water, flour and additives as described below, is started from the control panel and the
spiral, rotating together with the bowl, mixes the ingredients. To empty the bowl, stop the machine by pressing the
stop button, lift the guard and manually remove the dough from the bowl. Help yourself using a plastic or wooden
spatula to avoid scratching the bowl.
1) BOWL: container in which the various
ingredients to be mixed are inserted, is
equipped with rotation;
2) CONTRAST ROD: tool contrasting the
spiral, to improve product mixing;
3) CONTROL PANEL: device used to start
or stop the machine, and set the
processing time;
4) MOBILE GUARD: it is a guard used
prevent spilling dough and flour from the
bowl and/or prevent injuring the upper
limbs; it is connected to a safety micro
switch;
5) SPIRAL: tool used to mix the dough,
through rotational movement;
6) SPEED SELECTOR (ONLY FOR 2SPEED TAURO): select the wanted speed;
7) MASTER SWITCH: electrical device that
connects/disconnects the machine power
supply;
8) BOWL CONTRAST WHEEL: used to
facilitate rotating the bowl;
9) BEARING STRUCTURE: machine body;
10) FEET: used as support on the surfaces
and to stabilise the machine during
operation.
