Rotate the tool anticlockwise for
unhooking it..
8.4) Use the bowl lift lever to lift
the bowl in working position
and close the protection grid.
Rotate the grid and
insert the appropriate
tool.
1)
rotate the grid to
close the mixer
2) use the lift lever to
lift the bowl.

9.0) HOW TO WORK WITH THE MACHINE : THE CONTROL PANEL
A) Main switch led.
By pushing the buttons with
the digits you make rotate
the tool at the selected
speed , speed 1 is the
lowest while speed 6 is the highest.
B) Couple of buttons, by pushing them
together you can increase the selected
speed till the maximum of the rpm.
C) Couple of buttons, by pushing them
together you can decrease the selected
speed till the minumum of the rpm.
D Couple of buttons, by pushing them,
together you stop the mixer.
E) Main switch.
F) Indicator. It shows the absorbed
current of the mixer .
G) Regulation feet.
H) Protection grid with safety
microswitch.
I) Bowl lifting lever.
How to start the mixer:
•Press the main button in position I.
•Insert the tool.
•Insert the bowl.
•Lift the bowl
•Rotate the protection grid in the close position.
•Press one of the buttons with the digits to select the speed, the mixer will start to work.
•9.1) OPERATIVE RUNNING: Press the main switch F (see the exploded view from
position O to position I. Lamp A will light. Press button 1, (or another one of the
buttons if you already know the working speed) the tool will start to rotate at the
minimum speed, by pressing the buttons 2, 3 and the following till numberl 6 the
speed will increase till the highest one. By pressing together the couple of buttons
B, the speed gradually increases till the highest one. By pressing together the
couple of buttons C, the speed gradually decreases till the lowest one. By
watching the indicator F you can see the absorbed current of the mixer. Pay
attention not to exceed the power of absorbtion indicated in the rating plate.
9.2) END OF WORK: To remove the dough when the tool is still, rotate the grid; lower the
bowl with the lifting lever and rotate the tool anticlockwise to unlock it. Free the bowl from
the safety handles and take the bowl with the tool out.
Remind to switch the main switch off.

9.5) HOW TO WORK WITH THE MIXER.
Many problems rise from an improper use of the machine by the end user. Tg
of the advised quantities will be prejudicial to the quality of the working process
and to the endurance of the mechanical parts of the machine. It will be useful to
take as an indication about the maximum quantities the following capacity chart:

10) SAFETY DEVICES: The mixer is equipped with a series of safety devices that
saveguards the operator’s safety. These devices should
neither be tampered nor excluded and are to be checked
before starting the machine.
•Shutdown general switch in the electrical board:
interrupts the input of the open electrical board allowing a safe mechanical
maintenance.

9
•Inverter power blocking: interrupts the input in case of too much motor load.
•Thermal probe: interrupts the input in case of motor overheating.
•Fixed protections: all the covers fixed with screws can be taken off just for the
maintenance by skilled staff.
•Mobile protections: the movement of the grid and of the bowl drives two
microswitches that prevent the movement of the mixer if:
o The bowl is not in the high position.
o The grid is not closed.
10.2) SAFETY SUGGESTIONS:
•The machine should be installed in an illuminated and airy room.
•The user should wear adequate clothes, nonslip shoes,very well closed sleeves, do
not wear dangling clothes (ties, napkins, open jackets ecc.) to prevent the risk of
entangling.
11) USE AND MAINTENANCE DISPOSALS
According to our experience the first and most efficacious form of maintenance is cleaning
the machine. For cleaning and removing the dough waste we advice the use of a plastic
spatula or of a moist cloth . The outer surfaces can be easily cleaned with spray or neutral
soap.
EARTHING: The efficacy of the grounding of the mixer should be checked.
Should it be faulty or not correct serious accidents and also death can happen.
ELECTRICAL BOARD: general disposals.
The opening of the electrical board is allowed just to authorized staff. The
mixer with not protected electrical parts should never be left unattended.
The working of the machine where electrical parts are not protected is allowed
just in presence of skilled staff and just for the short time necessary for the
eventual repairs under the responsability of the staff.
The electrical plan is shown in the enclosed nr 1.

10
12)ORDINARY MAINTENANCE
ANY CHECK OR MAINTENANCE OPERATION SHOULD BE
CARRIED OUT ONLY WHEN THE MIXER IS UNPLUGGED AND
POWER IS DICONNECTED. The machine does not need particular
maintenance operations. Check worn-out level of the belts after the
first three months
ATTENTION: The machine is not waterproof, therefore whatever cleaning process must
not involve a jet of water.
If the power supply cable becomes damaged it must be substituted with a H07RN/F cable
with a cross-sectional measurement of 3x1,5 mm2.

16) RISKS, PROHIBITIONS, OBLIGAS.
17) ELIMINATION: The buyer is responsible if the machine goes out of order. The
disassembly of the mechanical and electrical parts should be done by the competent
staff.The machine should be eliminated locally following the local rules and regulations
Do not put out the
fire with water
Do not start the mixer before
having checked the protection
Do not clean the mixer while it
is running
380 V
The use of the whisk for too hard
dough can cause the breaking of
some parts that could also go out of
the grid.
Strong strikes can release the safety grid. The
machine stops immediately. DO NOT touch
anything without disconnecting the machine.
The weight of the bowl is 25 kg and should be lifted
only with the special grips.
Put the machine onto flat surfaces at a height
confortable for the operator.
Steadiness of the machine:if the machine
should be placed onto wet or greasy
surfaces or on unstable laces(ships,planes or
other), take off the feet and fix the machine
on the floor using the special holes.
