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. THIS WILL ALSO BE HARD TO PLACE
PISTON BACK INTO THE CYLINDER. THIS COULD ALSO
RESULT IN THE CUTTING OF YOUR PISTON RING AND
DESTROYING IT.
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.

THE SIX HEX NUTS (5), SLIDE SLIP RING (4)
DOWN AND OFF, THEN WITH SLIGHT
PRESSURE, PUSH PISTON RING (3) OFF
PISTON AND REMOVE 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.
