OPERATING INSTRUCTIONS
WARNING:
UNIT MUST BE PROPERLY OPERATED AND MAINTAINED TO PREVENT MACHINE DAMAGE OR PERSONAL INJURY. REVIEW
INSTRUCTIONS WITH ALL EMPLOYEES BEFORE USE.
I. PRELIMINARY START UP DIVIDER
A. REMOVE SMALL INSPECTION DOOR.
B. REMOVE PACKING, PACKING SLIPS, DOCUMENTS
AND OTHER OBSTRUCTIONS FROM HOPPER.
C. PLUG POWER CORD INTO PROPER RECEPTACLE.
D. PUSH DIVIDER START BUTTON AND TEST BUTTON
SIMULTANEOUSLY AND HOLD.
E. CAUTION (THIS WILL START DIVIDER ONLY)
F. CHECK ROTATION OF DIVIDER BY LOOKING
THROUGH SMALL INSPECTION DOOR. LARGE
GEAR FOR DIVIDER SHOULD BE TURNING (C.W.)
CLOCK-WISE.
G. IF THE GEAR IS TURNING IN THE (C.C.W.) COUNTER
CLOCK-WISES DIRECTION, CONSULT A PROPERLY
TRAINED ELECTRICIAN.
H. IF ROTATION IS CORRECT, YOU ARE READY TO
CONTINUE INSPECTION OF THE ROUNDER
CONVEYOR.
I. REINSTALL SMALL INSPECTION DOOR.
J. SHUT OFF DIVIDER.
II. PRELIMINARY START-UP
ROUNDER
A. MAKE SURE CONVEYOR IS SECURELY FASTENED
TO CABINET.
B. INSTALL GEAR MOTOR BREATHER (OIL VENT)
C. BE SURE CONVEYOR IS CLEAR AND NOT
OBSTRUCTED.
D. CHECK ROUNDER MOTOR CORD CONNECTION TO
CABINET RECEPTACLE.
E. TURN ON LARGE CONVEYOR POWER SWITCH.
THIS WILL START CONVEYOR MECHANISM.
F. CHECK CONVEYOR BELT, CONVEYOR BELT
SHOULD BE RUNNING FORWARD, OUT FROM
MACHINE.
G. IF CONVEYOR BELT IS RUNNING BACKWARDS,
INTO MACHINE, CONSULT A PROPERLY TRAINED
ELECTRICIAN.
H. SHUT OFF DIVIDER.
III. OPERATION OF DIVIDER
A. FILL THE OIL RESERVOIR WITH LIGHT WEIGHT
MINERAL OIL.
B. WITH THE SQUIRT BOTTLE SUPPLIED, APPLY A
SMALL AMOUNT OF MINERAL OIL TO THE INSIDE
WALLS OF THE DOUGH HOPPER.
C. OPEN THE VALVE LOCATED ON THE TOP GIB BAR
APPROXIMATELY 1/8 OF A TURN.
D. REMOVE BACK CABINET DOOR.
E. OPEN THE CYLINDER VALVE APPROXIMATELY 1/8
OF A TURN. THIS VALVE IS LOCATED ON THE OIL
PUMP INSIDE OF THE REAR DOOR.
F. REINSTALL THE BACK CABINET DOOR.
G. FILL THE HOPPER WITH DOUGH.
H. SET HOPPER COVER ON TOP OF DOUGH.
I. SWITCH LARGE CONVEYOR SWITCH TO THE “ON”
POSITION.
J. SWITCH SMALL CONVEYOR SWITCH TO THE “ON”
POSITION.
K. PRESS DIVIDER BUTTON.
L. HOPPER SHOULD BE OILED EVERY TIME NEW
DOUGH IS PLACED IN HOPPER.
IV. DIVIDING THE DOUGH
A. DOUGH IS PORTIONED IN THE MEASURING CUP
LOCATED ON THE DIVIDER SLIDE.
B. TO ADJUST THE WEIGHT, STOP THE
MACHINE.
C. LOOSEN THE STAR KNOB NUT (529MS-2D) AND
TURN THE SMALL HANDLE ON THE TOP OF THE
MEASURING CUP. NOTE: ALWAYS LOOSEN STAR
KNOB PRIOR TO ADJUSTING MEASURING CUP.
FAILURE TO DO SO CAN RESULT IN DAMAGE TO
CUP.
D. BY TURNING THE HANDLE, THE STOP COVER OF
THE CUP WILL MOVE UP OR DOWN. THE “UP”
(C.C.W.) MOTION WILL INCREASE THE DOUGH
WEIGHT. THE “DOWN” (C.W.) MOTION DECREASES
THE DOUGH WEIGHT.
E. FIND YOUR DESIRED DOUGH WEIGHT BY
WEIGHING THE DOUGH PIECES.
F. ONCE YOU HAVE ACHIEVED THIS, LOCK THE STAR
KNOB (529MS-2D) ON THE SIDE OF THE
MEASURING CUP TO KEEP SCALING ACCURATE.
V. SECOND STAGE DIVIDER
AFTER THE DOUGH HAS BEEN DIVIDED, IT WILL TRANSFER
FROM THE SMALL DROP CONVEYOR TO THE LARGE
CONVEYOR AND CONTINUE THROUGH THE SECOND STAGE
DIVIDER. IT IS THEN DIVIDED AGAIN AUTOMATICALLY INTO 3, 4
OR 5 EQUAL PIECES, ACCORDING TO THE SIZE REQUIRED.
A. THE SECOND STAGE DIVIDER HAS BEEN PRE-
ADJUSTED AT THE FACTORY. THE PRESSURE
PLATE HAS BEEN SECURED FOR SHIPPING
PURPOSES. VERIFY ADJUSTMENT PRIOR TO USE.
B. TO OPERATE THE SECOND STAGE DIVIDER YOU
MUST FIRST BE CERTAIN IT IS DISCONNECTED
FROM THE POWER SOURCE. NEXT RAISE THE
PRESSURE PLATE APPROXIMATELY 1 1/2” FROM
THE CONVEYOR BELT. THIS IS ACCOMPLISHED BY
LOOSENING THE WING BOLT (PART NO.F0604WB)
AND THEN RAISING THE HANDLE (PART NO.MPP15)
TO THE DESIRED HEIGHT.
C. LOCK THE PRESSURE PLATE IN PLACE BY
TIGHTENING THE WING BOLTS (PART
NO.F0604WB). RECONNECT POWER SOURCE.
D. SWITCH THE LARGE CONVEYOR TO THE “ON”
POSITION.
E. SWITCH THE SMALL CONVEYOR TO THE “ON”
POSITION.
F. PUSH THE DIVIDER START BUTTON. AFTER
CHECKING TO BE SURE THE CONVEYORS ARE
CLEAR.
G. AFTER DOUGH IS DIVIDED, DOUGH PIECES
SHOULD BE SPREAD INTO A STRAIGHT EVEN
SHAPE AFTER IT COMES OUT OF PRESSURE
PLATE. AN INCONSISTENT SHAPE WILL CAUSE
INCONSISTENT PIECES OUT OF THE SECOND
STAGE DIVIDER
NOTE: TO MUCH PRESSURE ON THE DOUGH PIECE GOING
THROUGH THE PRESSURE PLATE WILL CAUSE THE PIECE TO
ARCH FORWARD IN THE CENTER THIS CAN CAUSE THE MIDDLE
PIECES FROM THE SECOND STAGE DIVIDER TO BE HEAVIER
THAN THE END PIECES. TOO LITTLE PRESSURE WILL NOT GIVE
AN EVEN SPREAD CAUSING DOUGH PIECES TO BE HEAVY ON
ONE SIDE.
A. IF DESIRED RESULTS ARE NOT ACHIEVED.
STOP MACHINE.
B. REPEAT STEPS 2 THROUGH 6.
C. AFTER ACHIEVING DESIRED RESULT, MAKE A
NOTE OF THE SETTING OF THE PRESSURE PLATE
BY USING THE NUMBER LOCATED ABOVE THE
ADJUSTING HANDLE.

CLEANING PROCEDURES
THESE PROCEDURES ARE VERY IMPORTANT TO MAINTAIN
PRODUCT QUALITY AND MACHINE PERFORMANCE.
ALL A.M. MANUFACTURING MACHINE ARE TESTED WITH DOUGH DURING THE IN-HOUSE RUN-IN AND QUALITY AUDIT
PROCEDURE. ALTHOUGH THE MACHINE HAS BEEN CLEANED, SOME EVIDENCE OF DOUGH ON AND IN THE MACHINE MAY BE
DETECTED. THIS IS NORMAL. ALL PARTS IN CONTACT WITH DOUGH SHOULD BE WASHED THOROUGHLY AFTER USE, USING A
MILD SOAP AND WATER SOLUTION. DISASSEMBLY OF THIS MACHINE FOR CLEANING IS OUTLINED BELOW AND ILLUSTRATED
FOR YOUR CONVENIENCE.

1. MAKING SURE PISTON IS IN EXTENDED POSITION W / PIN IN UPPER HOLE.
2. PUT PISTON IN CYLINDER - GUIDING SHAFT INTO THE SPRING ASSEMBLY.
3. TAKE OTHER PIN AND PUT IT THROUGH SPRING ASSEMBLY AND LOWER SHAFT HOLE.
4. ROTATE CRANK UNTIL UPPER PIN IS VISIBLE AND REMOVE.
5. TURN CRANK UNTIL SHAFT COLLAPSES AND TWO (2) UPPER HOLES MEET, INSERT PIN AND PUSH
SLIDE OVER AND TIGHTEN ALLEN SCREWS.
6. BE SURE PISTON IS COLLAPSED BY MAKING ONE FULL ROTATION NOTING THAT PISTON DOSE NOT
COME ABOVE UPPER CYLINDER.
J. REPLACE GIB BARS & SLIDE AND ATTACH TWO (2) END BOLTS TIGHTLY.
K. TIGHTEN THE EIGHT (8) HEX HEAD NUTS ON THE GIB BARS.

FIGURE 1
STEP 1
USING AN ALLEN WRENCH, LOOSEN SOCKET
HEAD SCREWS (2) AND LIFT OFF DIVIDER
PLUNGER (MEASURING CUP) (3). WHEN A #2
OR #3 MEASURING CUP IS USED ON DIVIDER,
THE DIVIDER CYLINDER MUST ALSO BE
REMOVED FROM SLIDE FOR CLEANING.
STEP 2
LOOSEN EIGHT HEX HEAD BOLTS AT TOP OF
GIB BARS. USING WRENCH (1) REMOVE TWO
HEX HEAD SCREWS (4) AND PUSH DIVIDER
SLIDE (5) REARWARD TO EXPOSE CYLINDER
OPENING.
STEP 3
REMOVE CABINET DOOR (6).
FIGURE 2
SCALE - O - MATIC NAME PLATE
THIS PLATE HAS A 2-CHANNEL GROOVE THAT
CATCHES EXCESS OIL AND DRAINS INTO DRIP
PAN AT THE BOTTOM OF THE MACHINE. THIS
PLATE SHOULD BE REMOVED BY LOOSENING AND
REMOVING A SMALL ALLEN SCREW IN THE
CENTER OF THE PLATE. CLEAN PLATE, AND
CHECK PLASTIC DRAIN LINE TO SEE THAT IT IS
CLEAN AND FREE OF ANY SEDIMENT SO OIL CAN
DRAIN PROPERLY. DRIP PAN AT BOTTOM OF
MACHINE SHOULD BE EMPTIED EVERY DAY.
STEP 4
WITH CYLINDER OPENING EXPOSED,
REMOVE SEAL SCRAPER RING (7) AND
RUBBER “O” RING (8). CLEAN ALL EXPOSED
SURFACES INCLUDING “O” RING GROOVE
AND DIVIDING SLIDE OF ACCUMULATED
DOUGH, OIL, ETC. WIPE EXCESS DOUGH
FROM TOP AND INTERIOR OF CYLINDER.

GUIDE TO CLEANING
STEP 5
LOOSEN SOCKET SCREWS (9) ENOUGH TO SLIDE PIN
LOCK BRACKET (10) EXPOSING LOCK PIN (11). REMOVE
PIN (11).
STEP 6
INSERT CRANK HANDLE (12) THROUGH HOLE IN
CABINET AND ENGAGE WITH PINION SHAFT. CRANK
ONE COMPLETE TURN COUNTER CLOCK-WISE THUS
EXTENDING PISTON ROD UNTIL HOLE (14) IS IN LINE
WITH UPPER HOLE IN ROD (13).
STEP 7
PLACE PIN (11) INTO HOLE (14) TEMPORARILY. NOW
REMOVE PIN (15), CONTINUE TO CRANK UNTIL PISTON
(16) EMERGES FROM THE TOP OF THE CYLINDER. LIFT
OUT CAREFULLY BY HAND. THOROUGHLY CLEAN
PISTON AND CYLINDER TO REMOVE ALL ACCUMULATED
DOUGH WITH A MILD SOAP AND WASTER SOLUTION.
DRY THOROUGHLY AND COAT ALL SURFACES WITH A
LIGHT COATING OF DIVIDER OIL. TO REASSEMBLE,
REVERSE STEPS 1 THROUGH 7.
WHEN CLEANING OR ADJUSTING PISTON, DO NOT OVER
TIGHTEN ADJUSTING NUTS. THIS WILL OVER SPREAD
YOUR PLASTIC PISTON RING AND WILL CAUSE
EXCESSIVE WEAR, AND IT WILL ALSO BE HARD TO
REPLACE PISTON BACK INTO THE CYLINDER. THIS
COULD RESULT IN THE CUTTING OF YOUR PISTON RING
WHICH WOULD DESTROY YOUR PISTON RING.
DANGER:
ALWAYS DISCONNECT ELECTRICAL POWER
SOURCE WHEN CLEANING, MAINTAINING OR
REPAIRING THIS MACHINE....
REPLACEMENT OF PISTON RING
FIGURE 4
TO DISMANTLE PISTON IN FIGURE 4, REMOVE THE
SIX HEX NUTS (6), SLIP RING (5) DOWN AND OFF,
THEN WITH SLIGHT PRESSURE, PUSH PISTON
RING (3) OFF PISTON AND RUBBER “O” RING (2).
WHEN REASSEMBLING THE PISTON, A VERY
IMPORTANT STEP IS TO MAKE SURE THE SIX
NUTS (6) ARE NOT OVERLY TIGHTENED, MERELY
SNUG. AS THE RING WEARS OVER A PERIOD OF
TIME, CONTINUE TO SNUG UP THE SIX NUTS. THIS
PROCEDURE WILL NOT ONLY PROVIDE LONG LIFE
TO THE PISTON RING BUT WILL MAINTAIN FULL
VACUUM.
FIGURE 3
IMPORTANT: WHEN RE-ASSEMBLING, DO NOT OVER
TIGHTEN ANY OF THE SCREWS, AS THIS TENDS TO
STRIP THREADS CAUSING PROBLEMS IN THE FUTURE.
BE SURE RING ON PIN (11) OF FIGURE 3 IS SECURELY
FASTENED OVER LATCH (10). THIS WILL PREVENT
LATCH FROM MOVING, SHOULD THE SOCKET HEAD
SCREWS (9) LOOSEN DURING OPERATION.
