INSTALLATION INSTRUCTIONS
Dough Roller Installation:
Before starting the Installation process make sure you observe the following three
caution notes.
CAUTION
THE DOUGH ROLLER IS HEAVY, USE PROPER TECHNIQUE WHEN LIFTING.
KEEP BACK STRAIGHT, KNEES BENT, AND LIFT WITH LEGS.
USE GLOVES TO PROTECT HANDS.
CAUTION
NEVER LIFT THE DOUGH ROLLER BY ITS COVERS OR GUARDS.
CAUTION
BEFORE PLACING THE DOUGH ROLLER ON THE TABLE OR COUNTER MAKE
SURE THAT IT CAN SUPPORT THE DOUGH ROLLER’S WEIGHT WHICH IS
APPROX. 260 POUNDS (21”).
Bench Mounted
Select a location for your dough roller which has a substantial mounting surface, (see
the caution note above), and which has electrical service compatible with the load the
machine will place on it as indicated on the electrical data plate of the machine.
Position the machine while it is still in its packaging as close as possible to the desired
end location. Expose the machine by removing the outer packaging. Remove any
straps or fasteners securing machine to crate. Using at least two people, (one in the
front and one at the back of the machine), lift the dough roller from the resting surface of
the packaging and set the machine onto the counter or table as close as possible to the
desired end location. The machine must be sealed to the counter using the included
neoprene rubber under machine edges. Plastic Hole plugs are included to close any
unused holes in machine base.

INSTALLATION INSTRUCTIONS (Continued)
Optional Stand Mounted
Note:
One bottom guard bolt will have to be removed to mount machine to stand.
Select a location for your dough roller which has a level surface, and which has electrical
service compatible with the load the machine will place on it as indicated on the
electrical data plate of the machine.
Position the machine while it is still in its packaging as close as possible to the desired
end location. Expose the machine and stand by removing the outer packaging.
Remove any straps or fasteners securing machine and stand to crate. Machine will only
go on the stand one way. Using at least two people, (one in the front and one at the
back of the machine), lift the dough roller from the resting surface of the packaging and
set the machine onto the stand. Secure to stand using the provided fasteners.

641 DOUGH ROLLER
OPERATING INSTRUCTIONS
WARNING
ALWAYS USE CARE WHENEVER WORKING NEAR THE ROLLERS.
KEEP HANDS CLEAR OF DOUGH CHUTE.
Machine Preparation
1. Make sure the dough chute and trays are dry.
2. Dust the transfer tray (Item 200, page 10-1) with flour, Leave a little extra flour in the
tray to dust the bottom side of the dough before it is sent through the second set of
rollers.
3. Make your initial setting of the roller adjustment levers. Loosen knob, move handle,
then tighten knob. Dial numbers are for reference only.
Dough Preparation
1. Size and shape of the dough ball affects size and shape of the finished crust. For
round pies make a dough piece a fat sausage shape and flatten slightly.
2. Dust the dough pieces with flour before putting them in the machine.
Making a Crust
1. Place the dough piece in the top hopper chute (Item 206, page 10-1) end first.
2. When the dough piece comes out in the transfer tray it should be a little longer than
the diameter of the pie.
3. Dust the top of the dough with flour. There should be sufficient flour in the transfer tray
to dust the bottom of the dough.
4. Turn the dough piece a quarter of a turn in the transfer tray and slide it sideways into
the second pass rollers.
WARNING
NEVER PUSH THE DOUGH WITH THE TIPS OF YOUR FINGERS.
5. The second pass rollers should produce a crust of the proper thickness and about
round in shape. If the crust is too thin, open the lower rollers. If the crust is to thick, close
the lower rollers. If the thickness is right but the crust is too short, make the initial dough
piece bigger and open the upper rollers. If it is too long, make the initial dough piece
smaller and close the upper rollers. When you get the results you want, it is a good idea
to write down the setting numbers if the adjustment levers for future reference.
