1.3.1 Safety guards
Operation
The safety guards fulfill a dual purpose:
1. The safety guards protect the operator against inadvertent contact
with the rollers.
2. The machine is stopped by lifting up the safety guard. Raising the
safety guard even just slightly will cause the machine to discon-
tinue operation.

1.4 Safety instructions and information which must be followed
Read the operating manual before operating the machine.
The dough sheeters of RONDO are built for the food industry exclu-
sively for the sheeting, booking, final sheeting and cutting (using the
Cutomat) of dough pieces.
Any other use of these units is not in accordance with the purpose for
which they are built. Therefore, the manufacturer will not be liable for
any accidents or damage arising as a result of unauthorized use; the
risk in any such instance will be borne solely by the user.
Authorized use also means that the user must follow all instructions
prescribed by the manufacturer in respect of operation, maintenance
and service.
Any work on the electrical components of the machine, in particular the
correct professional mounting of the mains plug, may only be carried
out by qualified personnel who are familiar with the prescribed safety
instructions.
Defective cables and mains plugs must be immediately replaced by
qualified personnel.
Protective covers over the electrical controls and the mechanical mov-
ing parts may only be removed by professionally qualified personnel
and must be remounted before the machine is put back into operation.
Any unauthorized changes made to the machine, and in particular, to
the safety devices on the machine will automatically exclude any liabil-
ity on the part of the manufacturer for accidents or damage sustained
as a result of such changes.
The machine may only be connected to electricity using the mains
plug! No permanent electrical installation may be carried out using, for
example, terminal screws.
The machine may only be connected to the mains using the plug once
the machine has been fully assembled.
Before beginning any repairs, service or cleaning work on the machine,
the electricity supply to the machine must be interrupted (pull out mains
plug).

Operating manual 11
Safety devices on the machine may not be adjusted, shorted-out or
expanded.
Operation of the machine when any of the safety devices is out of order
is prohibited.
Defective safety devices must be replaced immediately with new origi-
nal parts from RONDO.
Machine parts located in the area in which the dough is being pro-
cessed, and whose surface coating becomes worn (e.g. chrome plate
worn off) must be replaced.
The machine may not be lifted on the machine base (SSO) when being
moved. The machine should be fastened and transported on a pallet.
The safety guard should be fastened in the upper position.
Reaching under the closed safety guard is prohibited!
The machine may only be operated with the machine tables mounted!
Ensure that conveyor belt tension is correctly adjusted!
Do not deposit any loose objects such as knives, tools, articles of cloth-
ing, etc. in the area where the dough is located.
Table models (STM) must be placed so as to rest properly over the
whole work table!
Check to ensure that there are no loose screws in the area where the
dough is located.

Operating manual 12
The machine may not be operated without the use of a scraper.
Flour dust can cause respiratory tract difficulties and allergies. Limit the
use of flour to a minimum.
The use of compressed air for cleaning the machine is not permissible.
The use of a dust extraction system in the bakehouse is recommend-
ed.
Cutomat: The safety guard must always be closed when the cutting
rollers are let down.
Cutomat: The replacement of the cutting rollers must be carried out
carefully and professionally. Cutting rollers located outside the cutting
area must be placed in the holding device located underneath the ma-
chine table.
Any disposal of the machine must be carried out in accordance with
environmentally-accepted practices. The operators are fully responsi-
ble for ensuring that such practices are followed.
This machine is not designed to be used in explosive ambient.
RONDO accepts no liability in the event of non-compliance with
any of the above safety instructions.

Position of the forked supports (16) when the machine table is hinged
down.
What to watch out for when mounting the forked supports on ma-
chines equipped with the “Cutomat” cutting device:
The foot (19) of the forked support must be set in such a manner that
the table stands level. This is the only way to ensure optimal function-
ing of the safety guard.

2.4.4 Tensioning the conveyor belts
Tense the conveyor belts only enough so that the heaviest pieces of
dough (max. 10 kg) can still be moved along the belt without the con-
veyor belt dragging.
Proceed as follows:
• Retighten the left and right tension nuts (20) so that they are even
and parallel
• Remeasure distance “X” on both sides using a millimeter measur-
ing instrument
Distance “X” must be identical on both sides.
• Switch on the machine (see 4 Putting the machine into operation,
3.5.4 Start push-button)
• Observe both the left and right running movement of the conveyor
belt
If the belt runs off toward one side, proceed as follows:
• Retighten the side where it runs off using a tension nut
or
• Loosen on the opposite side using a tension nut
• Monitor the belt, and if necessary, correct it until it runs exactly in
the middle of the table
Repeat this procedure several times, if necessary. Routinely monitor
the belt during the initial hours that the machine is operational, and if
necessary, correct again.
Tensioning and adjusting the conveyor belts demands patience!
Prior to carrying out each further correction, allow the machine to run
for at least 30 seconds.
Before putting the machine into operation, the conveyor belts must be
rubbed lightly with flour in order to prevent the dough from sticking to
the belt.
2.4.5 Mounting the dough catch pan (SSO)
• Remove the protective foil on the dough catch pan (21)
• Push in the dough catch pan on both sides
Option:
• Attach the flour catch pan (22) to the holder (23)

2.5 Requirements for putting the machine into operation
Power supply and frequency at the mains circuit to which the machine
is connected must be in accordance with specifications contained on
the sign “Electrical connected loads” (This sign is found on the cable
lead-through on the machine base).
Direct connection without a plug is prohibited! Ensure that the connec-
tion is made by professionally qualified personnel and that it is carried
out in accordance with local regulations (An electrical schematic is de-
livered with every machine and it is to be found next to the electrical
control in the rear of the machine housing).
• Connect the machine plug to the power supply
The machine may only be operated with tables mounted.
2.5.1 Ground fault interrupter is actuated when inverter is started
Leakage current flows through the inverter.
The inverter performs internal switching. Therefore, a leakage current
flows through the inverter. This leakage current may actuate the ground
fault interrupter, shutting the power off.
Use a ground fault interrupter with a high leakagecurrent detection
value (sensitivity amperage of 200mA or more, operating time of 0,1 s
or more) or one with high-frequency countermeasures for inverter use.
Reducing the carrier frequency value in n46 is also effective. In addi-
tion, remember that a leakage current increases in proportion to the
cable length. Normally, approximately 5 mA of leakage current is gen-
erated for each meter of cable.
