CHAPTER 3
THE USE OF THE SHEETER
3.1 - GENERAL DESCRIPTION
Doyon sheeters are designed to be used by qualified people in the pastry and bakery’s
business.
Open the tables and put the supports in the lowest position, [at 13 ¾ in., (35cm) from the
floor LMF624, fig. 3.1 and 3.2].
Fig. 3.1 Fig. 3.2
Also, lower the security bars (fig. 3.3 and 3.4) near the canvas.
Fig. 3.3 Fig. 3.4
LSBLMF-A.DOC 09/09/05
5
After these two procedures, plug the machine, but first, verify if the electric power is
correct.
There is one sideboard at the extremity of the trays (fig. 3.5), which must be placed out
from the canvas (open position), so it can collect the dough when it eventually comes off
the canvas.
Fig. 3.5
At the top of the sheeter, there is a recipient for small quantities of flour. This is to powder
the dough when it’s being worked. This recipient can be easily removed for cleaning (fig.
3.6).
Fig. 3.6
LSBLMF-A.DOC 09/09/05
6
The scraper above the sheeter’s superior cylinder (point A, fig. 3.7) which is fixed to it, can
be removed to clean the machine.
The scrapers of the sheeter’s inferior cylinder (point B, fig. 3.7) are fixed to the lateral parts
of the sheeter, to clean the cylinder and the canvas.

B
Fig. 3.7
Under each working board, there is a flour collector (fig. 3.8), which can be easily removed
by loosening the lateral screws from the tables (fig. 3.9) and pulling them.
Fig. 3.8 Fig. 3.9
The sheeter LSB516 and LMF624 has two rolling pins, which you can work with.
3.2 - MACHINE’S CHARACTERISTICS
LSBLMF-A.DOC 09/09/05
7
The LSB516 and LMF624 may work with a maximum of 6 Lbs. (2.7 kg) of dough. These
quantities may change due to the quality of the dough.
Roller openings from 0 to 1 ½" (0 to 38 mm).
It is excellent for puff pastries and soft dough.
3.3 - IMPROPER USE OF THE MACHINE
Doyon sheeter was designed to be used by qualified people in the pastry and bakery’s
business. Other uses will be considered improper.
The manufacturer is not responsible for any machine damages or personal injuries due to
improper use of the machine.
It’s not advisable to work with dough, which are not alimentary dough.

Voltage 120V
Speed Variable speed control: 20 speeds
Frequency [Hz] 60HZ
Amperage 4 Amps
NEMA configuration 5-15P
4.4 - ELECTRIC INSTALLATION
Doyon’s machines have an electric installation in compliance with the American (ANSI/UL
std. 763), Canadian (CSA std. C22.2 no. 1335.2.14) and European rules.
4.5 - SECURITY SYSTEMS
The potentially most dangerous area of these machines is the two superimposed cylinders
with convergent rotation movements.
So, there are safety bars that obstruct the entry in this area. Those safety bars are
completely built in stainless steel and designed in a way to allow the user to watch the
dough (fig. 4.2).
Fig. 4.2
LSBLMF-A.DOC 09/09/05

The machine can only begin its work if the security bars are in working position, that is,
completely down. The machine has an electric protection system that does not allow the
machine to work if the bars are not completely down.
If you lift the security bars, the machine will stop. To restart it, press the green button “Start
I” (fig. 4.3).
It is forbidden to remove, modify or damage the security bars of the machine.
4.6 - CONTROL PANEL
The fig.4.3 shows the control panel of the machine, with the following titles:
Up speed button

CHAPTER 5
ELECTRIC CONNECTION AND INSTALLATION
5.1 - INSTALLATION
THE MANUFACTURE IS NOT RESPONSIBLE FOR THE MATERIAL AND
PERSONAL DAMAGES THAT A WRONG INSTALLMENT MAY CAUSE.
The LMF624 is wheel-mounted so you can move it easily.
The surface where the machine (LMF624 or LSB516) will be in service must be solid,
horizontally leveled, in a way to prevent a possible instability and consequently a fall
during the working process.
The sheeter (LMF624) doesn’t need to be fixed on the floor, just tighten up the anti-vibrate
footing supports (fig. 5.1).
LSBLMF-A.DOC 09/09/05
Fig. 5.1
13
5.2 - ELECTRIC INSTALLATION
Make sure that the plugs you have in the room have the same voltage and power presented
on the machine’s nameplate.
The electric plug must be as close as possible to the machine.
Avoid plugging more than one machine into the same electric plug. In case you need to
plug more than one machine in the same electric plug, make sure that it has the electric
capacity for it.
See chapter 4.3 NEMA configuration for the plug on the machine.
5.2.1 - PRECAUTIONS
Warning! Take all the precautions in a way to avoid dangers of fire, electric shocks and
personal damages. Only qualified people are allowed to intervene in the electric parts of the
machine, always follow these rules:
1. Stop the machine.
2. Switch off the power, the general switch.
3. Unplug the machine.
4. Do the necessary repairs or maintenance.
5. Plug the machine only at the end.

4. Pull the manual driving down or up (fig. 6.1), or press the right or left pedal (fig. 6.2) to
activate the canvas. When using the pedal driving, the manual driving switch must be in
the middle.
5. The lever of fig. 6.3, controls the opening between the two cylinders, so you can obtain
different dough thickness.
6. The sheeter has 20 speeds, select the desired speed (fig. 4.3).
7. With the button to increase and decrease the speed, you can change the speed.
8. To stop the machine, you have to put the driving switch in central position and then,
press red button Stop “0” (fig. 4.3).
9. You may stop the machine’s work by lifting the security bars or pressing the emergency
stop. In this last procedure, to restart the machine, it will be necessary to twist out the
emergency button, and press the green button Start “I”.

CHAPTER 7
MAINTENANCE
WARNING: BEFORE ANY OPERATIONS OF MAINTENANCE AND CLEANING,
SWITCH OFF THE MAIN SWITCH OF THE MACHINE AND UNPLUG IT.
IF YOU NEED TO TAKE OFF SOME OF THE PROTECTIONS DURING THE
OPERATIONS, DO NOT START WORKING WITHOUT THEM.
7.1 - WHEN THE MACHINE IS NEW
When the machine is new, it’s advisable to try it with some dough before starting the
production, to remove some lubricator’s residue.
After the 1st working week, you have to control the belts tension.
7.2 - EVERY DAY
The machine must be cleaned every day, especially in the areas that have contact with the
dough.
To clean the cylinders, do not use knives, sandpaper, metallic objects, hard brushes or any
tools that may damage its surface. You may use plastic tools or soft sponges.
To clean the canvas use a soft brush.
Do not use toxic products, solvents, abrasive agents or any product that may damage the
surfaces or the dough’s composition.
Before switching the machine on, make sure that nothing has been forgotten on the
machine.
7.3 - EVERY WEEK
Every week, the cylinder’s scrapers must be cleaned.
To clean the scrapers above the superior cylinder, you have to dismount it by loosening the
two screws (fig.7.1).
LSBLMF-A.DOC 09/09/05
17
Fig. 7.1
The other scrapers are fixed under the inferior cylinder. So, in order to dismount them to
clean them, you have to:
1. Remove the two springs under the canvas from the studs (fig. 7.2).
2. Pull the scraper extremities until it’s loose.
3. Lift the scraper.
