DESCRIPTION/SPECIFICATION

Description

The Oliver Model 2003R is a variable slice thickness bread slicer which utilizes a new
and innovative way to slice bread. The bread is moved past a circular blade, which is
mounted to a moving arm, cutting each slice individually to whatever thickness is
selected. The slicer is designed for on-demand slicing allowing your customers to
choose a slice thickness which satisfies their needs.

The slicer employs a disc brake on the blade drive motor which mechanically engages
to stop the blade whenever the blade is exposed due to a door being opened, or after
the slicing cycle is finished.

NOTE

THIS MACHINE IS NOT INTENDED TO BE USED FOR SLICING WARM,
STICKY, NUT AND/OR FRUIT BREADS.

OPERATING INSTRUCTIONS

1. Automatic Diagnostic Check:

Close both doors. Turn the machine on. First the display reads “Vari-slicer” and the
software version. Next, the machine will automatically perform a diagnostic check on
the “end” and “home” proximity sensors (PS). You should observe the pusher going to
its “end” (right) limits and “home” (left). The pusher will then return to the home
position. You may then begin standard operation.

2. Standard Operation:

• Upon a successful completion of the diagnostic check, the machine is ready for
slicing.

• Hold open the left door with left hand.

• Place loaf on table.

• Slide loaf left onto the pins on the pusher so that pins penetrate the loaf, until it is

firmly against the back of the pusher.

• Close door(s).

NOTE

MACHINE WILL NOT OPERATE IF EITHER DOOR IS OPEN.

• Select the appropriate thickness setting. Slicing will begin immediately.

• Wait for bread to be sliced. After the final slice, the bread will be in the right hand

compartment.

• Open the right hand door and remove the loaf.

• Close the door

• Repeat above steps for each loaf.

3. Stopping:

If a slice gets jammed, press STOP to stop slicing, turn power off, disconnect, and
lockout machine before trying to clear the machine.

CAUTION

DO NOT OPEN DOORS WHILE SLICER IS OPERATING. DOING SO WILL CAUSE

SLICING TO STOP.

MANUAL DIAGNOSTIC MODE

• The machine may be put into Manual Diagnostic Mode to check several functions of
the machine. To enter this mode, simply do the following:

• Turn power off.

• Depress the "1" and "2" keys simultaneously for approximately 5 seconds or until display

illuminates.

• There are nine different tests that can be performed in this mode. To exit this mode,
depress "Power" key at any time. The tests are:

1. Jog Test - The display will read "Jog Test 3=Next" and "1=Left 2=Right". Depress
the "2" key to jog the pusher to the right. Depress the "1" key to jog the pusher to the
left. Depress the "3" key to continue to the next test.

2. Knife Arm Test - The display will read "Knife Arm Test" and "Press&Hold 1
3=Next". Depress the "1" key and hold it to turn only the arm motor on. Continue

depressing it until the arm clutch engages, and the arm goes through a down-then-up
cycle. Depress the "3" key to continue to the next test .

3. Blade Motor Test - The display will read "Blade Motor Test" and "1=on 1=off
3=next ". Depress the "1" key to turn the blade motor on. Depress the "1" key
again to turn the blade motor back off. Depress the "3" key to continue to the next
test.

4. Loaf Sensor Test - The display will read "Loaf Sensor Test" and "Not Detected
3=Next". Insert a small piece of paper in front of the loaf sensor, between the infeed
door and the blade guard. Once the beam is broken, the display will read “Object

MANUAL DIAGNOSTIC MODE

- Continued

5. Door Test - The display will read "Door Test" and "1=Left 2=Right". Any of the
door open sensors can be checked individually by opening the infeed door, the blade
guard, or the outfeed door. The display will indicate which is open. Depress the "3"
key to continue to the next test.

6. Slow Jog Test - The display will read "Slow Jog Test 3=Next" and "1=Left
2=Right". Depress the "2" key to jog the pusher slowly to the right. Depress the "1"
key to jog the pusher slowly to the left. Depress the "3" key to continue to the next
test.

7. Set Heel – The display will read “Set Heel 1=Down 2=Up” and “Heel Val = 8”.
This is to program the final slice thickness. The value is in eighths of an inch. For
example, Heel Val=8 would be 8/8 inch or 1 inch, or Heel Val=7 be 7/8 inch. The
range of Heel Values is 6 to 12, which equates to ¾” to 1 ½”.

8. Continuous Cycle - The display will read "Continuous Cycle" and "1=Start

3=Next". Depress the "1" key to begin the continuous cycle test. The machine will

first go through its self calibration, then it will operate as if it is slicing bread even
though there is no bread detected. Once the pusher gets near the blade, slicing will
stop, the pusher will return to its home position. The display will read “Slicing…”
and “Thickness: 3/8”. The cycle will repeat itself. To exit this mode, depress the
"1" key to stop. Depress the "3" key to continue to the next test.

9. Key Pad Test - The display will read "Key Pad Test". Once in this test, any key can
be depressed, and the display will indicate which key it is. To exit this test, depress
the "3" key, AND HOLD IT IN FOR APPROXIMATELY 5 SECONDS to return to the
Jog Test.
