•Turn the power on
•Adjust volume control bar (Indications shown in
table 1) to the position to the weight of dough
•Place the dough piece in the middle of the
rounding plate and flatten it by hand.
If the dough is very stiff it is usefull to
flatten the dough by a dough roller.
In case of sticky dough it is advisable to
flour the dough and rounding plate lightly.
•Place the plate correct onto the moulding table
(see chapter 5.1)
Inserting the rounding plate improperly
can cause damage to the machine.

Table 1
Remarks:
The position of this bar determines how far the dividing head jumps back before rounding. In this way the volume of the
rounding chambers can be determined. Therefore this position is related to the weight of the dough piece that should be
divided.
As the correct setting depends on the dough consistency, it is a question of experience.
When the volume of the rounding chambers is too small, the dough pieces will be damaged. When the volume is too big,
they will not be sufficiently rounded.

9JUDGMENT OF THE RESULT
The following information will help you to obtain the best possible result. When operating the
machine, always observe the following adjustment options: volume, pressing time and rounding
time.
A) The dough pieces do not have the same weight.
-Make sure the dough piece is put exactly in the middle of the plate and flatten it a little
by hand. The dough should stay inside the circles on the plate. If this is not the case, then
you will see when the pressing ring comes down. The pressing ring is not flat on the
rounding plate and the dough outside the circles will not be pressed and rounded.
-Be sure that the dough has had the right pre-proofing time (dependent of the
consistency of the dough, but usually 15 minutes).
-Press the dough by pressing the handle longer in the press position. As soon as the dough
appears under the pressing ring, it has been pressed long enough.
B) The dough pieces have not been rounded enough.
-Turn the volume bar (figure 2-3) to a lower setting.
-Round the dough more by keeping the handle longer in the rounding position.
-Try a combination of both.
The dough will now be rounded more intensively.
C) The dough pieces have a dot on top.
-Turn the volume bar (figure 2-3) to a higher setting.
-Check if the weight of the dough piece is in accordance with the capacity of the machine.
D) The dough pieces have a damaged skin.
-The dough pieces have been rounded too long. Round shorter.
E) The machine presses the dough through the gap between the pressing ring and the rounding
plate.
-The dough piece has been pressed too long. Press shorter
For a good result observe the weight range of the machine. Eventually check the machine
plate. The table in chapter 1 “Product information” mentions the weight ranges of the
different types of machines.
