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.
(see page 14-1)
For all Machines
1. Be sure machine is clean and dry.
2. Make sure power switch is in “Off”position.
3. Check machine nameplate for correct voltage and frequency.
4. Connect machine to a power source that matches nameplate requirements.
5. Switch power “On”and check for proper operation of the machine.

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.

MAINTENANCE
WARNING
ALWAYS UNPLUG THE DOUGH ROLLER BEFORE PERFORMING
ANY TYPE OF MAINTENANCE TASK.
Cleaning
The machine should be cleaned daily, more often during heavy use. Use a damp, soft
cloth on the fixed parts of the machine. Trays and scrapers may be taken to sink for
cleaning.
Removing Scrapers
Remove the scrapers and slides as follows. Reverse the procedures to install them.
1. Long top scraper and tip.
a. Grasp the scraper with both hands.
b. Press down to compress springs and release the retainer.
c. Shift sideways toward the belt guard.
d. Swing the end opposite the guard away from machine.
e. Slide the scraper sideways away from the guard to free the second
end. When reinstalling the scraper make sure the long slot is toward the
belt guard.
2. Long bottom scraper slide and tip.
(first remove the long top scraper as described above)
a. Look under the slide before you attempt to remove it. Note the angles
on the bottom of the slide that hold it in place.
b. To remove the slide grasp it with both hands, one on either side, and
lift sharply to both compress the springs and lift the angles clear of the
pins that support and retain the tray.
c. Pull the tray toward you to remove it from the machine.
3. Short top scraper and tip.
a. Grasp the scraper with both hands.
b. Press down to compress springs and release the retainer.
c. Shift the scraper toward the center of the machine.
d. Swing the end closest to belt guard of the scraper away from the

Removing Scrapers (Continued)
4. Short bottom scraper slide and tip.
(first remove the long top scraper as described above)
a. Grasp the scraper with both hands.
b. Lift up sharply to compress the springs and release the retainer.
At the same time, raise the end of the slide so it will clear the lip of the
transfer tray.
c. Swing the inboard end of the scraper which is furthest from the belt
guard toward the roller.
d. Slide the scraper sideways toward the belt guard until the end furthest
from the belt guard clears the stud assembly.
e. Swing the end furthest from the belt guard away from the roller until the
scraper is in front of the stud assembly.
f. Slide the scraper toward the center of the machine to remove it.
g. When reinstalling the scraper you must lift the retainer plate on the stud
assembly furthest from the belt guard so that the hooked end of the
scraper can slide under the plate and around the stud.
General Notes on Disassembly
1. DO NOT LOOSEN THE ACORN NUTS OR THE STUD ASSEMBLIES! They
are factory set to assure proper contact of the scraper tip on the roller.
2. The white nylon scraper tips are easily removed from the scraper bar fro
cleaning by sliding them off with your fingers.
3. WHEN REINSTALLING THE WHITE SCRAPER TIP, MAKE SURE THE
SMOOTH SIDE OF THE TIP (NOT THE STEPPED SIDE) WILL BE TOWARD
THE DOUGH DURING OPERATION!
Lubrication
1. All bearings are permanently lubricated and do not require further lubrication.
2. Add a drop or two of medium weight food safe oil to the oil cup on the chain
idler arm every 200 hours. The cup is located above the shaft of the main drive
pulley and slightly under the dough hopper casting.
Service
If you properly care for your Oliver Products Company Dough Roller, it will give you long,
trouble free service. If replacement parts are required, order them from the factory. Refer
