1.) IS PUNCH FRAME A CASTING OR FLAME CUT PLATE? (IF FRAME IS A CASTING, THEN OUTER EDGE WILL BE THICKER THEN THE REST OF THE FRAME)
2.) WHAT IS THE HORIZONTAL CENTER TO CENTER DISTANCE BETWEEN THE TWO PROBE RODS ON THE FRAME?
3.) DO THE PUNCH CYLINDERS HAVE SQUARE OR ROUND END CAPS?
4.) DO PUNCHES HAVE PUNCH EXTEND/RETRACT LIMIT SWITCHES? IF NOT, IS THE FLANGE UNIT MACHINED FOR THEM? (IF UNIT IS MACHINED FOR LIMIT SWITCHES, THERE WILL BE A SLIT ABOUT 2" CUT INTO THE SIDE OF THE FLANGE UNIT CASTING PARALLEL WITH PISTON ROD.)
5.) CONDITION OF UP-DOWN GUIDE RODS AND BUSHINGS:
ARE THE GUIDE RODS RUSTED?
ARE THE GUIDE RODS BENT?
IS THERE SLOP BETWEEN BUSHINGS AND GUIDE RODS?
LIST ANY OTHER OBSERVATION THAT MAY BE HELPFUL.
ARE THE NUTS THAT HOLD THE GUIDE RODS IN FRAME TIGHT? IF NOT, IT IS HARD TO TELL IF LOOSENESS IS IN BUSHING OR NUTS.
6.) ARE THERE ANY LEAKS IN THE PUNCH CYLINDERS OR UP-DOWN CYLINDERS? (IF SO, THE ITEM(S) WILL NEED TO BE REPAIRED..)
