SAFETY INSTRUCTIONS

Every effort has been made by Oliver Products Company to provide you with a safe
machine. It is essential, however, that machine operators and maintenance personnel
observe the following safety precautions.

1. Before attempting to operate your dough press read this manual. Never allow an
untrained person to operate this machine.

2. Make sure that the machine is only connected to a properly grounded electrical
supply source of sufficient capacity for the load the divider will put on it. Always
unplug the machine when it is not in use.

3. Always make sure the machine has been disconnected and locked-out from the
power supply before cleaning or servicing.

4. All guards must be in place before starting the machine.

5. Keep your hands away from the moving parts of the machine.

6. Use only proper replacement parts.

7. Do not wear loose fitting clothing. Shirt tails should be tucked in.

8. In addition to these general safety instructions, also follow the more specific safety
instructions given for the different areas of the machine in the operating instructions.

619-MDP Dough Press

DESCRIPTION/SPECIFICATION

Description

The Oliver dough press consists of a hopper which can be loaded with dough from an
approximate minimum of ten and one half pounds up to forty pounds, (depending on the
density of the dough). The lid and sides of the hopper are made of hard anodized and
Teflon impregnated cast aluminum. The pressing plate located at the bottom of the
hopper is manufactured of a food grade plastic and is raised by hydraulic pressure to
compress the dough. This makes the machine ideal for puff and fine pastries and
products requiring dough lamination.

The hydraulic pump is powered by a two horsepower, totally enclosed motor. The
system has a built-in four and one half gallon hydraulic oil tank making the machine
totally self-contained and is provided with casters to allow for easy movement about the
work area.

OPERATING INSTRUCTIONS

Before You Start

THE DOUGH PRESS SHOULD ONLY BE PLUGGED INTO AN OUTLET
WITH THE SAME VOLTAGE AS STATED ON THE NAMEPLATE

Before starting a new dough press with THREE PHASE
you should check to see if the motor is running in the correct direction. Remove the front
cover by removing the four thumbscrews which secure it; you will also have to remove
the handle from the directional control lever before removing the front cover. Once the
cover has been removed you should be able to see the fan end of the motor on your
dough press, this fan MUST

EXTENDED RUNNING OF A DOUGH PRESS WITH THE MOTOR

ROTATING IN THE INCORRECT DIRECTION WILL SEVERELY
DAMAGE THE HYDRAULIC PUMP OF YOUR MACHINE.

If the motor is rotating in the incorrect direction turn the machine off, disconnect it from
the power supply and have a qualified electrician reverse two of the three power wires in
the plug at the end of the power cord. DO NOT move the ground, (green), wire.

ALWAYS HAVE ELECTRICAL WORK DONE BY QUALIFIED
ELECTRICIANS ONLY.

Recheck the dough press making sure that it is now running in the correct direction,
(clockwise looking at the fan end of the motor). Each time the machine is moved to a
different power supply or has electrical work done which could alter the motor rotation,
the motor must be rechecked for proper rotation.

Basic Operation

• Make sure the floor of the hopper has been lowered before attempting to open the lid
of the divider.

• Open the lid and load the dough into the hopper. Spread the dough over the floor of
the hopper making it approximately the same height, this is done to eliminate large
air pockets.

CAUTION

rotate in a clockwise direction.

Basic Operation (Continued)

• Close the lid and turn the handle in a clockwise direction making sure it is secure.

• With the machine running grasp the control valve handle and lift it to start the floor of

the hopper up. Hold it in this position until the light on the starter switch box comes
on, the light indicates that the preset pressing pressure has been achieved. Let
loose of the valve handle when you see that the light is on.

• Press the control valve handle down slightly to release the pressure on the lid so it
can be opened. Open the lid.

• The dough can now be removed and the above process repeated.

WARNING

NEVER

RISING DOUGH MAY CAUSE EXPLOSIVE PRESSURES TO DEVELOP.

• If dough has been left in the machine and the lid handle is difficult to turn,
recompress the dough by lifting the control valve handle until the light come on. This
will raise the floor of the hopper, after doing so lower the hopper floor by pressing
down on the control valve handle. This may have to be done more than once if
dough has been left in the machine for quite awhile. With the hopper floor all the
way down try to open the lid again. The handle should turn easily, if it does not,
recompress the dough and try again.

• The dough press is designed so that if dough is left in the hopper it will eventually
force the hopper’s floor to the bottom, thus allowing the dough to vent to the outside
of the machine through openings on the left side. If dough is coming out of these
openings follow the steps above, recompressing the dough a number of times before
attempting to open the lid.

LEAVE DOUGH IN A MACHINE WITHOUT OPENING THE LID;

WARNING

NEVER

FORCE THE LID HANDLE OPEN

MAINTENANCE

WARNING

ALWAYS MAKE SURE THE MACHINE HAS BEEN DISCONNECTED

FROM THE POWER SUPPLY BEFORE CLEANING OR SERVICING

Cleaning

The exterior and contact surfaces should be cleaned daily using common cleaners.

Occasionally, or as required, remove the front and rear covers to allow access to the
drive chamber. There you should remove any build up of flour and dough particles in the
base of the machine and from around the motor. When finished replace the covers.

Lubrication

The machine requires no lubrication but the oil level in the hydraulic system should be
checked periodically. To check the oil level remove the rear cover by removing the four
knobs which secure it to the divider, then remove the tank breather/cap and determine
where the top of the oil is in relation to the top surface of the tank. Fill with oil to within
approximately one inch of the top surface. If necessary add HYDRAULIC OIL
it to the proper level, DO NOT OVERFILL
the hydraulic oil in the system approximately every three years.

Hydraulic Oil Specification

The hydraulic oil used in your divider should be made of good quality base stocks
compounded with the following additives: anti-wear, anti-oxidation, antifoaming, and
antirust. In addition it should be an “ISO” viscosity grade No. 32.

Hydraulic Filter Replacement

At least once a year the throw-away filter on the hydraulic system should be replaced,
more often when under heavy use. To replace the filter disconnect the machine from the
power supply, remove the front cover and unscrew the old filter. Replace it with a new
one. The filter is located on the return line near the tank. After replacing the filter run
the machine for five minutes and then check the oil level in the tank. See “Lubrication”
above for how to check the oil level. Add oil if necessary to return it to the proper level.
