Safety and Warranty
TYPICAL MIXER-RELATED DANGERS
Look at Figure 22: there are certain mechanical dangers relative to this machine:
A - Pinching, cutting, squeezing, impact danger in the area of spiral rotation.
B - Trapped-in and pinched hands: this danger occurs in the area between turning bowl and pillar, bowl bottom
and stand base; the danger occurs on both mixer sides because the rotation can be reversed.
C - Trapped-in and pinched hands: between the bowl guide rollers and the bowl
D - Pinching, cutting, squeezing, impact danger in the area of drive transfer to the spiral
E - Pinching, cutting, squeezing, impact danger in the area of drive transfer to the bowl
F - Squeezing, pinching, and injuring occur in case of a sudden cover drop in the area between the bowl rim
and the cover, between the sides of the dough stopper and the cover. Electrical shock hazards occurs.
G - In case of contact with live parts (for instance those inside the switchboard enclosure).
THE FOLLOWING DANGERS ARE ASSOCIATED TO THE USE OF A MIXER
DUE TO THE INHALATION OF POWDER PARTICLES
• Risk of inhaling our and/or other agent particles with inammation of the respiratory tract (rhinitis, asthma,
excess lacrimal secretions, etc.)
HYGIENE DANGERS
• Health dangers may result from contact with moulds, rotting materials, rodents and insect penetration, etc.
• Unacceptable changes of food products (i.e. contamination by micro-organisms or foreign matters).
DANGERS RELATED TO THE LACK OF COMPLIANCE WITH ERGONOMIC CONCEPTS
• The operators may incur into physical lesions/pain due to wrong gestures and postures.
• This may occur when lifting and handling heavy loads (pouring a full our bag into the bowl, pouring water
etc., or even taking heavy dough pieces out of the bowl).
All the foregoing risks have been eliminated or minimized by the design and implementation of the protections
and safeties describe in this manual.
MIXER SAFETIES
1. Mobile cover in combination with safety micro to protect the bowl interiors and, more specically the spiral
area. It can be made of round bars welded together (grid) for the machines sold outside Europe (see for
example Figure 23) or solid with a slot to pour the ingredient in. Lifting the cover while the mixer works will
trigger the emergency safety stopping all moving parts as soon as the distance between the bowl rim and
the cover is less than 75 mm (see Figure 23; spiral and bowl come to a complete stop within no more of 4
seconds. To restart the mixer moving parts, you rst need to close the cover down onto the bowl.
2. Fix covers: These covers are secured by xations that cannot be removed without using a special tool;
these protections (if correctly installed) will make access to the drive system, spiral, and bowl impossible.
In detail (Figure 24): The components used to transfer the drive to the spiral are protected by the guards
shown in pos. 1 - 2 - 3 - 4 - 5. The components used to transfer the drive to the bowl are protected by the
guards shown in pos. 6 (two pieces) and 4. The areas where the drive is applied between the two bowl
rollers are protected by the xed guards shown in pos. 7 (whose position must be determine a maximum

6
Safety and Warranty
distance of 4 mm from the bowl). The dough stopper shown in pos. 8 also works as a xed guard because
it combines with the cover shown in § 1, whilst the bowl basically prevents access to the rotating spiral.
3. Emergency stop button Pos. 8 Figure 25; when pressing this button (please do not emergency stop the
machine as a rule. Strictly use this control in real emergency cases) all mixer parts are stopped and power
is disconnected from the mixer and all of its moving parts. To restart the machine, reset the emergency stop
button by turning it in the direction shown by the arrow on its head.
It is absolutely forbidden to open/remove the machine safeties and/or bypass its protections unless required
by some stringent situation and prior to the implementation of suitable measures to minimize all related
risks. Even in this case, remember to assign this task to a skilled person authorized to perform works on the
machine. As soon as the reason for removing/bypassing a safety are resolved, make sure to t them back on
and secure them in place using their original xation systems. Reactivate all safeties before starting the mixer
again. Failure to comply with the foregoing instructions will involve the full liability of the trespasser for any
direct or indirect damage/injury cause to persons, animals, or assets.
CONTROLLING THE EFFICIENCY OF THE SAFETY SYSTEMS
The e󰀩cient and perfect conditions of the safeties described must be checked at the beginning of each new
day and/or work shift as following:
1. Test the bowl mobile covers and its safety micro switch. The test must be done with the empty bowl. Start
the mixer in speed 2; while the mixer turns very-slowly the cover up and stop as soon you hear the micro
triggering; Do not ever put any part of your body between cover and bowl. Make sure that:
- The micro actually activates and stops all moving parts of the mixer as soon as the cover reaches less
than 75 mm away for the upper ridge of the bowl (75 mm is not acceptable).
- Spiral and bowl must stop within 4 seconds from the switching of the micro switch (use a chronometer
to measure this time; if in doubt let the measurement be repeated by an expert with professional tools (for
instance an oscilloscope).
- Make sure that no start command is available when the micro switch is activated. If the test is negative
DO NOT USE the mixer and ask for service by a skilled technician or electrician qualied for checking the
mixer electrics.
2. Fix Guards. Perform a visual control to make sure that all guards are in the right place, e󰀩ciently operating
(without any visible damage or alteration), and locked with the special fastening and clamps. If the test
is negative DO NOT USE the mixer and ask for service by a skilled technician or electrician qualied for
checking the mixer electrics.
3. Testing the emergency pushbutton. The test must be done with the empty bowl. Start the mixer in speed 2;
while the mixer turns press the emergency push-button and make sure that:
- All moving parts stop and the push-button remains pressed down.
- Spiral and bowl must stop within 4 seconds from the switching of the push-button .Use a chronometer to
measure this time; if in doubt let the measurement be repeated by an expert with professional tools (for
instance an oscilloscope).
- Make sure that no start command is available when the emergency stop is activate. If the test is negative
DO NOT USE the mixer and ask for service by a skilled technician or electrician qualied for checking the
mixer electrics.

Safety and Warranty
OTHER AREAS OF POSSIBLE RISKS
Risk of pinched hands and getting trapped between bowl and stand. Although the clearance between stand
and bowl is compliant with the requirements of the EN Standards 453, you should account for some risk of
getting trapped in this area. The risk increases proportionally to the amount of stress applied to force through
(for instance using a leg). The same risk but to a lesser extent applies in the area between the bottom of the
bowl and the upper face of the stand base. For this reason, it is forbidden to approach any body part to the
dangerous areas of the mixer while it runs. If needed, make sure to disconnect the machine and unplug it from
the power supply. Risk of getting pinched, cut, or trapped in the moving spiral! Although the bowl cover (solid
or grid) is compliant with the requirements of the EN Standards 453, you should account for some risk of a
person reaching the spiral through the clearance (< 75mm) formed between bowl and cover every time when
the cover is lifted before the safety micro activates and stops the machine. Please refrain from any attempt
to reach the spiral across this free gap. There is no reason why you should do so and most of all you expose
yourself to serious risks for your health. The same risk occurs when the cover is opened and you attempt
to reach the spiral by quick arm gestures, and even worse if the bowl is empty. According with the EN 453,
the maximum stop time is of 4 seconds, which is a condition widely complied with by all (brand new) mixers.
However, this time is enough for a person to reach the spiral before it comes to a complete stop, especially
if the bowl is empty (with dough in the bowl, the machines gets to stop quickly). Risks of bone and muscle
lesions: this is often the result of lack of ergonomic postures while working. The employers are responsible for
the administration to the operators of comprehensive information on the residual risks resulting from the use of
the mixer, as well as for the training of the operators on safe use, protection measures, and behaviours to be
avoided.
OTHER AREAS OF POSSIBLE ELECTRIC RISK
The enclosure of the power switchboard Pos. 8 Figure 1 as well as any other housing of any live electric
component are identied by special signs of voltage-relate danger. There is a residual risk of accidental
contacts with live components during maintenance operations only (otherwise impossible during normal use).
As repeatedly stated in this manual, the mixer must be unplugged and power must be disconnected before any
intervention on the machine; A disconnected plug must be hanged visibly so that anyone can easily and quickly
check if the unit is not branched. Electric works may be strictly performed by skilled, licensed electricians
qualied and capable of ensuring the required level of technical quality, safety, and compliance with the actual
standards and regulations.
PLEASE NOTE!
Make sure that all safety signs and warnings are in good state and always clearly readable. Immediately
replace them when they become teared or worn.
RESIDENTIAL USERS: Vendor assumes no liability for parts or labor coverage for component failure
or other damages resulting from installation in non-commercial or residential applications. The right
is reserved to deny shipment for residential usage; if this occurs, you will be notied as soon as
possible.

Installation
The place where the machine will be kept and / or used must be in accordance with applicable laws and
ensure adequate protection from accidental damage, deterioration and weathering agents. The access ways
should provide enough clearance for handling the mixer without risk to the safety of people and the machine
itself. Flooring, walls and structures must comply with the applicable regulations and standards, and be suitable
for bearing the reference load plus an adequate safety factors; They must be easy to clean and disinfect. The
oor must be at, not sloping, compact, and without holes and bumps. The in-house electrical and grounding
systems must comply with the applicable laws and regulations, and should be designed, manufactured,
maintained, and controlled by a licensed, qualied rm, if so required by law, with powers of testing and
releasing a statement of conformity. The in-house upstream switchboard should be tted with e󰀩cient safeties
against any current overloads, short circuits, phase-to-phase, phase-neutral (if applicable), and phase-ground
faults.
TRANSPORTATION, HANDLING AND PLACEMENT
Depending on the nal mixer application and contract agreements, mixers are packed (Figure 6 / A) on the
pallet and secured with straps. Alternatively (Figure 6 / B) they can be packed in a cardboard box, put on a
pallet and secured with straps (usually for EU countries) or even in a cage or wooden crate (countries outside
the European Community). Pallets and/or cages and/or boxes are loaded on the transport vehicle and secured
with crossbars and/or wooden blocks appropriately positioned/fastened to a load bearing part of the vehicle
in order to prevent misplacements during travel. To hoist and handle a pallet, cage or crate, use a lifting fork
of suitable capacity. Weight data are also stated on the mixer identication plate; Slip the lifting fork into the
special grooves at the base of the pallet/crate/cage until they protrude by at least 200 mm on the opposite side.
PLEASE NOTE:
Do not use handling systems, tools and equipment other than those that are described herein. When handling
and / or transporting the mixer or parts thereof take all the necessary precautions to avoid, or minimize,
the occurrence of risks to people, animals, and other assets. Remove the machine from its packaging,
separating the materials by type (plastic, wood, etc.) and deliver them to dedicated collection areas, assigned
to authorized persons for disposal in accordance with current environmental laws and regulations. Check
the machine and make sure there are no missing parts; if in doubt, consult the manufacturer. To remove an
unpacked mixer from the pallet, crate, or cage, lift it up using a strap of adequate capacity (the weight of the
machine is indicated on the plate as well as in this manual) slipped underneath the mixer head at the outlet
(see Figure 7) and hooked up to a lifting device of adequate capacity (jib cranes, bridge cranes, etc.). The
strap should be compliant to the relevant legal requirements and must have a maximum width of 40 mm and
a length so that each connecting length from below the head of the base to the hook of the lifting device is at
least equal to 1200 mm; so that the band remains at and as close as possible to the column of the base: It is
forbidden to hang up the strap to the tips of a lifting fork as it might slip o󰀨 and break away with consequent fall
of the mixer and risk of injuries to the bystanders; Also avoid swinging of the suspended mixer that may cause
instability of the forklift.
Lift the machine gently, avoiding jolts and vibrations; once raised it could tip slightly; this is absolutely normal.
Simply be careful to handle it with very gentle movements until it stands rmly on all wheels. Place the machine
in a safe and secure place, away from any risk of impacts and damages. The mixer standing on the oor with
its wheels can be moved around by simply pushing it; the two front wheels are pivoting, whilst the two rear
wheels are xed. The working area around the machine must be kept as clear as possible from surrounding

10
Installation
obstacles in order to facilitate the normal operations (i.e. cleaning); usually leave 1000 mm clearance on each
side, unless the mixer is set near an escape route, in which case you must leave at least 1200 mm free.
Before using the machine, secure the two front legs to the oor (do not allow it to rest only on the wheels,
because it vibrates abnormally during kneading). Look at Figure 8:
• Remove the two xed covers located on the sides of the base (also see pos. 1 Figure 16).
• Use a hex wrench to loosen the lock nut (pos. 2) until the thread of each leg (pos. 1) is disclosed and until
the two faces show up as in Figure 8.
• The threaded portion of each leg has two faces just above the foot area; grip these faces with the hex
socket wrench (17 mm) supplied with the mixer, and turn the leg shafts until there is no more stress on
the front wheels (this means the front wheels must be able to rotate freely around both the horizontal axis
and vertical axis of rotation); Finally, lock the feet by screwing and tightening the respective nuts (pos. 2);
Do this for both feet and as much as possible by the same extent so that the mixer stands perfectly at
(use a feeler gauge to measure the gap underneath the front wheels). If you need to move the machine
(for example for cleaning), repeat the same operation in the opposite order and let the mixer stand on the
wheels.
ELECTRICAL CONNECTIONS
Let electrical works be strictly performed by skilled, licensed technicians technically qualied and informed
on the relevant safety issues, regulations and standards; Please note: electric works must be followed by
the release of an o󰀩cial statement of compliance. On delivery of the machine and before connecting to the
mixer to your power network, ensure that the voltage, frequency and number of phases of your power line are
the same as those required by the manufacturer on the identication plate and in the wiring diagrams on the
relevant Annexes.
The machine is supplied with a cable with three phase conductors and a ground conductor; The terminal plug
is not included and must be procured and wired by the buyer (preferably at a qualied electrician) based on
the type sockets available. Please mind the number or poles and power requirements (see attached wiring
diagram) when purchasing the plugs. When making the connection of the conductors keep in mind that the
ground wire must be attached to the terminal clamp corresponding to the longer and larger pole. When the
mixer is successfully wired, check for spiral and bowl to rotate counter-clockwise (viewed from above); if not
reverse each of the two phase conductors (BEWARE: make sure to avoid exchanging phase and grounding
wires). Use the in-house grounding system, and periodically check its e󰀩ciency. Do not connect grounding
wires to gas or water pipes or other metal structures. The power cord must be kept away from hot and/or
moving parts and should not impair the way of people, things or animals. The plug must be easily accessible
and well visible.

11
Operation
FUNCTION AND USE
The mixer should be only used by experienced persons who are trained, authorized and informed on the
residual risks and the precautions to be used to eliminate or minimize them. Mixers are no-manning machines;
operations, which may be required (using the controls, adding ingredients, picking sampling, etc.) can and
should be performed by a single operator at a time; never allow more than one man at a time to work at the
mixer. If so required in the contract, Omcan can provide the training (including practice) and the necessary
instructions (by the way, the same as in this manual) for the safe and proper use of the machine. The user
shall:
• Identify the persons to assign to the use of the mixer.
• Provide them with information and training (including practice) necessary, also in accordance with the laws
on safety and health in the workplace.
• Implement the necessary procedures to minimize exposure to possible residual risks resulting from the use
of the mixer.
PLEASE NOTE!
No person who is not qualied as described in this manual, should be allowed to work with and / or use
the machine. Omcan accepts no responsibility for damages/hazards to people, animals, things, directly or
indirectly resulting from non-compliance with the instructions in this manual.
GENERAL INFORMATION FOR NORMAL OPERATION
1. At the beginning of each day and / or shift check if the covers are undamaged and secured with all the
means available and if the safety devices of the machine are e󰀩ciently operating.
2. To load our do not pour a whole bag at once into the bowl; start by making it lighter (extracting as much
our as possible with a scoop), then put the bag on the bottom of the bowl, open the bag bottom and let
our slowly and progressively out. Make sure to disperse as little our dust as possible in the air; keep the
next bag a little inclined, with the opening close the existing our bunch and pour by avoiding as much as
possible the dispersion of our particles.
PLEASE NOTE!
It is very important that you reduce the weight of the our bags before lifting and pouring. Mind the foregoing
instructions for pouring our into the bowl. This can be a weary task and you should minimize the risk of hurting
your back and muscles. (Remember this is a frequent operation and handling lighter weight will save the risk of
injuries).
3. The provisions also apply to the lling of water into the bowl; pour a few litres at a time using only small
vessels. The best solution for safety purposes is obviously to make use of an automatic dosing of water.
4. For routine use of the machine, the operator must wear safety shoes with reinforced toes; no additional
PPE are required, unless instructed by the risk assessment procedure of the employer (remember that this
assessment is a requirement in the legislation in force in the European Community). For example, if the
above instructions were disregarded and full, heavy our bags were loaded in the bowl, the operator and
all bystanders would be exposed to a lot of dust with a health risk from inhalation (rhinitis, asthma, excess
lacrimal secretions, etc.); In this case, the employer and operator would be entirely responsible for taking
all possible measures to eliminate or minimize any such risk to the safety and health of people, animals,

12
Operation
and assets directly or indirectly resulting from the release of dust particle in the air and surrounding
environment (for example, before adding the our, you should check that nobody is near the machine and
that bystanders at least wear a respiratory protection mask with adequate ltering capacity in relation to
the particle size of the our (indicated in the data sheet, if available, or measured by the employer for the
purposes of the aforementioned risk assessment). The employer is responsible for identifying additional
PPE that may be required (for example maintaining food hygiene).
5. If the machine is equipped with a grid cover, let the spiral rotate at speed 1 until all the our is mixed with
water and only then switch to speed 2; this is a great way for limiting the dispersion of our dust caused by
the kneading tool operation.
6. Do not try to recover the our deposited on parts of the machine; It may be contaminated and will a󰀨ect the
purity and hygiene of the mix with a risk to consumers. The operators also may be exposed to a serious
risk to their safety if they put hands, ngers, etc. in areas where there are moving parts (e.g. between bowl
and cover, or bowl wall and column).
7. To control the normal stop, press the STOP button, Pos. 5 Figure 2.
8. If you press the emergency button the machine stops and the electricity to the motors is switched o󰀨: Use
it only if absolutely necessary, otherwise use the STOP button Pos. 5 Figure 2. Once pressed, it must be
reset to restart the machine.
9. The same result is obtained by lifting the bowl cover; in this case to restart the machine must rst close
the cover. In normal cases, do not stop the machine by lifting the cover to avoid exposing yourself to
unnecessary risks and shortening the life of the mixer safety system; use, rather, the STOP button pos. 5
Figure 2, as mentioned in the above paragraph.
10. If you need to add liquid ingredients during the kneading cycle you can do so through the appropriate slot
on the solid cover (see Figure 10).
PLEASE NOTE!
Never try to force your hand through the slit, there is no reason to do so and you could risk getting stuck,
dragged in and badly bruised by the spiral in motion and crushing and cutting between the spiral and column.
If your mixer has a grid cover (only with machines not intended for the European Community) you can pour the
liquid through the grid itself making sure to avoid protruding your hands through the openings of the grid.
11. If it is necessary to add our during the kneading cycle, even in modest amounts, you can pour it through
the appropriate slot on the full cover; However, if the cover is a steel grid, do not pour our from above
through the gird: but stop the machine, lift the cover and add the required amount of our without jerking
your hands or the scoop. Move your hand or the scoop and drop our on several points of the dough; so as
to limit the dispersion of our dust in the air.
12. When cleaning, wear shoes with reinforced toes, waterproof gloves and appropriate dust mask.
13. To remove the dough from the bowl, break it into small parts that can be re-manipulated easily and safely.
Dough is not rm (it is much more unstable, the more it is soft), it tends to stretch downwards and is di󰀩cult
to collect with the hand, if not in small portions; the centre of the mass varies continuously and causes, a
continuous change in the equilibrium and e󰀨ort that the operator has to maintain. If you consider that the
operator must bend the torso to remove the portions, which can increase the risk of muscle and bone pain
with increasing masses drawn and moved by hand.
14. Do not put hands between the rotation bowl and the column wall for any reason; the distance between the
two parts meet the requirements of security, but there still remains a residual risk of catching and dragging
in if someone placed their hands or even the arms in this area.

13
Operation
15. IMPORTANT! Before starting the machine, check the following:
a) make sure that the line voltage of the mains supply corresponds to the identication plate and in
the relevant wiring diagram. If not, do not connect the electric supply and contact your dealer or the
manufacturer.
b) verify that the direction of rotation of the spiral is anti-clockwise (viewed from above).
SWITCHING THE MACHINE ON/OFF
After connecting the machine to the power outlet place the switch in Figure 3 to position I - ON. To turn o󰀨 the
machine, place the switch in Figure 3 to position O - OFF.
KNEADING CYCLE
1. Fill the ingredients in the bowl and close the cover. IMPORTANT! Do not put excessive amounts of
ingredients over maximum capacity stated by the manufacturer into the bowl; This might cause serious
damage to the machine and, in particular, to the motor drives. The manufacturer is in no way responsible
for damage caused by failure to comply with these instructions.
2. Turn the switch in Figure 3 to position ON - I.
3. Set the timer on the operating time in speed 1 and 2. To do this, turn the front dial to the red indicator to the
desired time.
4. Press the start button of speed 1 (Pos. 1), if you want to perform an action of pre-mixing at low speed to
allow the ingredients to bind together; when the time set on timer (Pos. 2) is over, the kneading tool (spiral)
will automatically switch to speed 2 and will remain there for the time set on the timer in Pos. 4. After this
time the machine will stop. You can switch from speed 1 over to speed 2 immediately or at any later time by
pressing the button in (Pos. 3).
PLEASE NOTE!
If the machine is equipped with grid cover do not start in speed 2 immediately, but operate the machine in
speed 1 at least for the time necessary for the  our in the bowl to bind with the water and, not less than 120
seconds; This reduces the development of airborne  our dust and the risk to people’s health.
5. If the cycle is in progress and you lift the cover, the remaining cycle time at the time of stopping will be
saved. To resume the cycle from where it left o󰀨, lower the cover and press the START button on the speed
that was in place at the time of stopping. If in the middle of a cycle you press the emergency button (Pos.
8), the machine will stop and the timer will return to its initial values.
6. During the mix cycle is possible to reverse the direction of rotation of the bowl with the selector Pos. 6;
this can be useful, for example, to “mix in” any “unblended” our in the dough remaining on the bottom of
the bowl. IMPORTANT! The direction of rotation of spiral and bowl during normal kneading cycle must be
anti-clockwise (viewed from above). If needed, you can reverse the direction of rotation of the bowl for the
time strictly necessary. However, as soon as possible return to the normal direction of rotation to prevent
possible, even serious damages due to abnormal stress (mechanical overload on the transmission and
overheating of the motor windings).
7. Once the cycle is over, lift the cover and pull the dough out. To facilitate the operation it is possible to rotate
the bowl by pressing the button in (Pos. 7) so as to bring the dough in the best position for the operator;
please note that if you release the button, the bowl stops.

14
Operation
Maintenance
8. If you want to stop the current cycle, just press button in (Pos. 5); the machine stops, but the timer keeps
the elapsed time stored. To restart the machine, press the same START/speed button that was enabled at
the time of stopping. So, the kneading cycle will pick up where it left o󰀨. After pressing the button (Pos. 5)
wait until the spiral stops completely (a few seconds) before lifting the cover. In normal conditions do not
stop the machine neither by lifting the cover, nor by pressing the emergency button pos. 8.
9. When nished with the machine, always turn the main switch (Figure 3), to position OFF - O; in lengthy
stationary periods, a thorough cleaning of the machine would be advisable.
PLEASE NOTE!
Except where otherwise stated, maintenance should be strictly done after:
• Pressing the emergency stop button Pos. 8 Figure 2 and Figure 11.
• Turning the main switch Figure 3 on O - OFF.
• Disconnecting the plug from the power supply (the disconnected plug must remain visible so that one can
check by eye that the machine is unplugged) so that nobody else can accidentally start the machine or any
of its parts.
Before removing any cover or guard, and disable any safety, take appropriate measures so that others are not
exposed to any risks (i.e. cordon o󰀨 the operations area with chains or white-red striped ribbons, hang warning
signs and boards and/ or written information warning people the of the risks); reassemble the protections and
fasten them with the xings provided and reactivate the safety devices when the reasons for their removal have
been resolved. Any non-compliance with this manual and / or improper use, or inconsistency with the expected
use of the machine causing direct or indirect damage to people, animals, things, will be a full responsibility of
the reference person.
PERIOD MAINTENANCE AND CHECK-UP
Before any operations, make sure to implement the safety measures described in this manual.
• Perform accurate cleaning of the mixer at the end of each day or work shift.
• At the beginning of each day or shift, check all guards and safeties.
ADJUSTMENT OF THE TENSION AND REPLACEMENT OF THE DRIVE BELT
Always have a set of at or star screw drivers available before starting any maintenance Ideally procure
yourself also a set of hex plug wrench (Allen) and a set of hexagonal keys. IMPORTANT! A belt that is too tight
is likely to wear out quickly; if, instead, it is too loose it will not perform as expected and will not transfer any
drive. If the belt tension is not correct, its performance and service life will be drastically reduced. The concept
for determining whether a belt is worn out depends on the brand and the diameter of the pulleys, as well as the
length of the belts themselves. This manual contains the instructions of the manufacturer of the belts installed
by the factory on the new mixer. However, the mixer can be equipped with any other belts from di󰀨erent
manufacturers, provided they are equivalent or superior in terms of features, performance and durability; In
this case, the supplier and/or installer will have to provide detailed instructions on how to properly adjust their

• Release both belts pos. 1 and 3 with knobs pos. 2 and 4.
• The belts in pos. 1 can be easily pulled out from the bottom.
• To pull the belts Pos. 3 out: pull them out of the grooves on pulley pos. 5; pull them above the cross
member pos. 6 carrying the mounts of the front caster; and nally take them (Pos. 3) completely out.
• Fit the new belts in the place of those you removed ensuring they t well in the pulley grooves; the belts
pos. 3 must be pulled over the cross member in pos. 6 then inserted in pulley grooves pos. 5 and pos. 7.
• Adjust the tension of the belts in accordance with the instructions of the reference manufacturer.
IMPORTANT! To ensure the best performance of the machine and longer service life of the belts it is
crucial to replace all drive belts, not just some.
REPLACING AND ADJUSTING THE BOWL GUIDE ROLLERS AND THEIR MOUNTS
Look at Figure 19, each of the two bowl roller sets comprises an idle roller pos. 1 and a mount pos. 2; their
function is to counteract the force of the spiral whose force would otherwise deform the bowl. Replace the roller
pos. 1, provided by Omcan with the bearings (pos. 3) every time when excessively worn or unserviceable:
• Undo the screws pos. 4 and washers to remove the complete unit.
• Undo the screws pos. 5; Be careful not to drop the roller pos. 1 with the pin pos. 6 and not to lose the
washers pos. 7 and rings pos. 8; then grip the whole assembly and secure it at the mount pos. 2.
• Use a plastic hammer and a hard punch on the pin pos. 6 to get it out of the bearing pos. 3.
• Insert the new roller pos. 1 with bearing pos. 3 on the mount pos. 2 so that the hole matches with the holes
pos. 9 of the mount pos. 2.
• Insert the pin pos. 6 as far as possible in the holes pos. 9 of the mount and the centre hole of the roller
(place the shims pos. 8 between bearing pos. 3 and sides of the support pos. 2), then press down with a
hard plastic hammer; tighten the screws, pos. 5 at the ends of the pin pos. 6 with washers pos. 7.
• Reassemble the group in the machine, screwing but not tightening the screws pos. 4 and its washers, in
the threaded holes of the column after passing them through the slots pos. 10 of the mount pos. 2.
• The bowl not being perfectly cylindrical, the roller pos. 1 must be placed so that it touches the wall of the
bowl at the point where it is closest to the roller itself; to do this move the mount pos. 2 along the slots pos.
10, then, once you nd the right position, lock it by tightening the screws, pos. 4.
• Check that the distance between support pos. 2 and bowl is not more than 4 mm, this is vital to minimize
the risk of gripping, dragging or crushing between the roller pos. 1 and bowl; If you are unable to comply
with the aforementioned maximum distance do not use the machine and immediately contact Omcan.
REPLACING AND ADJUSTING THE MICROSWITCH ASSOCIATED TO THE BOWL
COVER
Look at Figure 20, the safety micro pos. 1 of the cover pos. 2 is mounted to the bracket pos. 3 with two
screws pos. 4 (they are not shown in the picture but are described here below). If you ever come to replace
this micro switch, all you need to do is disconnect the wires and remove the screws pos. 4. Strictly have a
licensed electrician who is familiar with the mixer electrics connect the new micro pos. 1. The switch should
operate with normally closed contacts (the lifting of the guard forces the opening of contacts by the plate pos.
6). The position of the actuator pos. 5 of the microswitch to the plate pos. 6 of the round pin pos. 7 must be
such that the opening of the contact (and therefore the stop command) occurs when the distance between
the lower edge of the cover pos. 2 and the upper edge of the bowl is less than 75 mm. The new switch must
have physical characteristics and performance equal to or better than the old one; in particular, the same

18
Maintenance
measurements and the same centre distance of the mounting holes, a provision to adjust the switching point,
and a tight closing of the contacts to the lowered guard. If the above is respected you should not need to adjust
the position of the microswitch (eventually, the through holes for the screws, pos. 4, are slightly slotted to allow
minor adjustments); However if necessary, loosen the screws, pos. 8 and move the holder with microswitch
along the slots pos. 9 to nd the right position; At the end, secure the mount pos. 3 by tightening the screws,
pos. 9. Two screws with hexagon socket (grains), t into the grooves of the pivot pin pos. 10 and prevent
the round bolt pos. 7 from moving against the pin itself. If you need to extract the grains, before tightening
check threaded holes and niches are in line and spread on a thin layer of grains LOCTITE 243 or equivalent.
Frequently check the tightness of the screws pos. 4 and the screws, pos. 8, as well as the grains described
above.
MOUNTING/DISMOUNTING THE PILLAR
Before starting make sure to wear safety shoes with reinforced toe and safety helmet. This operation should be
performed by one man alone provided that the following instructions are followed:
Look at Figure 21, remove the column pos. 1 as following:
• Fully lift the bowl cover pos. 8 and let it fall back.
• Loosen each of the 4 screws (pos. 2) one at a time until the column pos. 1 rests on the bottom of the bowl.
• Hold rm and position the column pos. 1 as vertical as possible, while extracting the screws pos. 2 and
washers; move the column pos. 1 out of the head pos. 4; then pull it out; the weight of the column is not
particularly heavy (indications below for the di󰀨erent models of the machine), however it is important to hold
it well in order to keep it balanced on the arms; keep arms close to the body as much as possible while the
bust leans forward, rather bend your knees and keep your upper body upright as much as possible; this is
in order to minimize the risk bone/muscle pains; comply with the instructions given by the employer during
education and training on safety and health in the workplace.
To t the pillar back on:
• Lay the column pos. 1 on the bottom of the bowl and push it below the head so as to align it through holes
of the plate pos. 5 with the corresponding threaded holes pos. 6 under the head pos. 4.
• Insert the screws through holes pos. 2 and screw them alternately, but without tightening them.
• Visually check that the column pos. 1 is parallel to the axis of the spiral pos. 7, then rmly tighten the
screws pos. 2 always checking the parallel position of the column with the axis of the spiral. To do this use
a torque wrench set to 46 Nm.
• Turn on the machine and be ready to press the emergency button pos. 8 Figure 2 and start in speed
1. Check that the spiral pos. 7 does not hit the column pos. 1 during the rotation. If it does press the
emergency stop button and process.
ELECTRIC MAINTENANCE WORKS
Due to the high risk and seriousness of some electrical accidents, every even minor operation (like replacing a
fuse) directly or incidentally involving the electrical system of the machine, must be strictly and only performed
by licensed electricians who are familiar with the technical and statutory requirements for safe works. Also,
remember to have them reading this manual before they start to work.

Maintenance
Troubleshooting
CLEANING
Before any operations, make sure to implement the safety measures described in this manual. Make sure that
the mixer is clean and in perfectly neat conditions. Accurately clean and remove all residues at the end of each
day or shift. Perform a thoroughly and accurate cleaning every time when you are going to leave the mixer o󰀨
service for longer that twelve hours. This is very important to prevent the occurrence of biological risks resulting
from moulds, bacteria etc. Cleaning must be performed as following:
• Make sure that there are no bystanders near the mixer.
• Always wear a protection mask to avoid inhaling particles (a suitable mask should have enough ltering
capacity to stop our particles) and goggles, Ventilate the room for about 15 minutes after the end of
cleaning; if possible always perform cleaning outdoor.
• Use a vacuum cleaner to remove our, clots, and dough residues from the bowl, the dough stopper, and
the cover (for grid covers use a vacuum cleaner with a thin crevice tool); if needed to remove sticking
materials, use a brush. For grid covers use a synthetic, medium hard brush. Before cleaning with a vac and
strictly on occurrence, use compressed air to remove residues from the hardest parts to reach.
• Impregnate a cloth with drinking water and clean all food contact areas, including bowl interiors and rim,
dough stopper, bowl cover, pillar, spiral, and the area underneath the hear over the bowl. If needed,
dismount the pillar and wash in potable water, or eventually with neutral dish soap. In this case, make sure
to rinse it o󰀨 well in potable water. Before tting it back on, dry the ange and the holes of the xing bolts.
• Use a clean cloth (wet but not soaked with drinking water) to clean the remaining areas of the machine
and dry them with a clean cloth. Do not use steel tool to avoid scratching the reference areas. Do not use
high-pressure water jets. Before using the mixer again, make sure that all parts are dry. BEWARE: residual
humidity may induce our clotting and incrustations that may be di󰀩cult to remove in the long term.
Mixer malfunction and/or failure Possible causes Remedies
