        SECTION 2 - MAINTENANCE & ADJUSTMENTS


        CUTTING TABLE SQUARENESS
        The cutting table must be properly aligned to the
        cutting line. If there is any misalignment adjust the
        table accordingly.


        TESTING FOR CUTTING TABLE SQUARENESS
        1.	 Check the cutting table alignment by any of the
            following methods:
            a) Check the cutting stick for a notch that has
               been cut by the blade. If the notch is not parallel
               to the edge of the stick the table is not aligned
                                                                            Figure 1 - Cutting Table Bolts
               properly.                                                  Front View (front cover removed)

            b) Place a small block under the clamp. Lower
               the clamp and knife using the blade change
               switch. Use a square to check the alignment
               of the blade to the sides of the cutting table.


        CUTTING TABLE ALIGNMENT
        1.	 Determine what correction is necessary (see
            “Testing for Cutting Table squareness”).


        2.	 Remove the front and rear covers (four Allen
            screws each).

        BACKGAUGE SQUARENESS
        The backgauge must be parallel to the cutting line.
        If there is any misalignment adjust the backgauge                                        A
        accordingly. Test cutting table squareness before                                         A
        testing the backgauge.

                                                                             B                                    B
        TESTING FOR BACKGAUGE SQUARNESS
        1.	 Cut several sheets of paper at the same time.
            Align them against the right side of the cutting
            area and evenly against the backgauge.

        2.	 Remove and discard the pieces closest to the               Figure 3 - Backgauge Drive Cover Rear Bolts
            operator.

        3.	 Turn the remaining sheets over and push them
            against the left side of the cutting area and
            against the backgauge.
                                                                              A
        4.	 Observe any excess trimmings from the cut. If
            there are any pieces left over, perform the
            backgauge alignment.

        BACKGAUGE ALIGNMENT
        1.	 Determine what correction is necessary (see
            “Testing for Backgauge Squareness”).
                                                                       Figure 4 - Backgauge Drive Cover Rear Bolts
        2.	 Remove the two screws A, see Figure 3.

        3.	 Remove screw A and remove the backgauge
            drive cover, see Figure 4.
                                                                                                            A
        3.	 Loosen, but do not remove, the two bolts B on              A
            the left side of the backgauge, see Figure 3.
                                                                                                                  B
                                                                       B
        4.	 Loosen, but do not remove, the two nuts B on
            the right side of the backgauge, see Figure 5.

        5.	 Adjust the two bolts as necessary to “square
            up’ the backgauge to the cutting line.

        6.	 Test for squareness. When satisfactory, lock                   Figure 5 - Backgauge Adjusting Bolts
            the bolts from steps 3 and 4.

        7.	 Reinstall the backgauge drive cover.

        REAR CALIBRATION POINT
                                                                       6.	 Repeatedly push the <NEXT> key until “PROG:1”

        line. It is referred to as the rear calibration point.             Repeat this procedure until there is no difference
                                                                           in the lengths of the op side and non op side
        For reference purposes:                                            pieces of paper.
        Using a known size piece of paper, the piece of
        paper closest to the operator is the operator side
        piece and the piece of paper towards the rear of
        the machine is the non-operator side piece.

        PROCEDURE

        1.	 Write “op side” on the operator side of the sample
            paper and “non op side” on the non operator side
            of the sample paper.                                               C: 26” 496        PROG: 0

        2.	 Cut the sample paper in half.                                      1: 674.9 mm         2: 050.0 mm

            For example: If the sample paper is 17 inches
            and it is cut lengthwise, the cutting distance must
            be set to 08.50 inches.                                                  Option 1
                                                                                     Add or subtract from this value
        3.	 Carefully align the pieces together and determine
            the difference in millimeters, if any, in their lengths.
                                                                                Figure 2 - Back Point Adjustment
        If the “op side” is longer you need to decrease the
        rear point value.

        If the “op side” is shorter you need to increase the
        rear point value.

        4.	 Access the rear point adjustment (by default the
            first item is rear calibration point). See detailed
            instructions in this section.

        5.	 Divide the distance measured in step 3 in half.
            Increase or decrease the value of option 1 ac­

                                               Installation Check List

        1) Check voltage on the machine after electrical wiring is done by checking the T and L on the
        terminal board to see if it is between 208v -232v, if not you will have to install a buck booster
        transformer

        2) Turn on the machine and check the control panel by pressing of any of the buttons and to see
        if the LED display is ok

        3) Check the clutch by pushing the fine adjustment knob on the front of the machine, by pushing
        it in and out this is to check to see if the gap on the clutch sounds right if not please refer to the
        instructions later in this manual.

        4) Input a size into the control panel press the run button verify if the # C and # I matches,, if so
        then you do not have to do a thing . If it does not match, then you have to adjust the low speed
        adjuster in the main electrical panel on the bottom of the box (white knob) by turning the knob
        very slightly at a time and by pressing the run button till the sizes matches the control panel

        5) Put a stack of paper on the right side of the cutter and select a size, then press run, make a cut,
        now move the stack to the left side of the cutter make a cut, if there are any shavings, you will
        have to adjust the backgauge till you have no more shavings and the backgauge is square. Please
        refer to the maintenance manual on page 2.5 to show you how to do this adjustment.

        6) Put a full stack of paper into the cutter, make a cut then check it by taking a sheet form the top
        and one from bottom and comparing them to see if the paper is cut at a angle. If it is at an angle
        you must make an adjustment, instructions are in the later part of this manual.

        7) Put a 10" cut into 1# place, then press next, then put a 5" cut into 2# then press next then
        press end twice then press the auto button and the machine will go to the first cut, cut some
        paper for the 10" cut, then cut the 5" cut and put them together to see if they match, if not, you
        must adjust the rear calibration point till it matches both cuts. Instructions are on page 5.5 of the
        maintenance manual

        8) This is to check for the maximum cutting ability, Place a full stack of heavy paper stock into
        the machine and make a cut, if it cut all the way thought then it’s OK, if not, go to the later part
        of this manual for more information.

        9) Check the pressure gauge on the front of the machine by making a cut. It should be about 50
        to 60 p.s.i.

        10) Check the foot pedal to see if the clamp comes down and is operational.

        11) Check and see if the knife cutting line light is on if not replace it. Instruction are in the latter
        part of this manual.

                                       Cutting Table Vertical Adjustment

        1) Take a full stack of paper and put it into the machine and make a cut, compare the top sheet
        with the bottom sheet to see if it is at a angle or if it matches if not go to the next step.

        2) Take off the front and bottom back cover.

        3) Loosen but do not remove these bolts there are 2 of them that are horizontal bolts in the front,
        the other 2 of them are vertical in the back of the machine, these 4 bolts are 19mm.

        4) There are 2 smaller vertical bolts under the back of the cutting table, on the left and the right
        side These are the ones that change the angle of the cutting table loosen the 2 nuts on the bolts
        so you can adjust the bolts.

        5) By determining the angle needed to be adjusted by the cut sheet that you have done, lower or
        raise the bolts evenly on both sides, by making a cut and adjusting the bolts, till it is vertically
        square.

        6) Tight all the nuts and bolts and make another cut of a full stack of paper to confirm the
        adjustment has not moved. If there is no change, you are finished. If so you have to re-start from
        1) until it is square.

                                        (wires SS,UL )
                                        2. The backgauge rear safety switch (LS-E) is broken
                                        (wires M, 25 )
                                        3. The fuse is blown ( fuse 3 )
                                        4. Mark –II programmatic control is out of order

        (b) Mark-II starts              1. Backgauge locking handle does not reset
            completely but              (wire SS ,RL )
            can not operate.            2. The clamp doesn’t return to top position ,
                                        Mark-II can not run (wires SS, RL).

        (c) Backgauge 	moves            1. Backgauge low speed adjuster is broken (SB)
            in high speed, but
            low speed can’t be
            engage.

        (d) Encoder problems.           1. Cut position is incorrect.
                                        2. After calibration the rear position ,backgauge move forward in
                                        high speed, then locked.
                                        3. Backgauge moves forward a section in high speed , then

                                             in the down mode            on the hydraulics
                                                                              #8

             Note : This is how to check the top Ls-u and bottom Ls-d switches to see if
                     they are ok
                    1) Remove back top cover and find the switch Ls-u ,next take the
                       allen screw off one side of the Ls-u switch and tilt it to the side
                    2) Remove the side cover where the Ls-d switch ,so you may touch
                       the switch when you have to
                    3) Now have someone hold the arm of the Ls-u switch in the up
                       position
                    4) Turn on the power to the machine
                    5) Now press the two yellow buttons and release the arm of the Ls-u
                       switch ,then touch the Ls-d arm ,next then move the arm of the
                       Ls-u into the up position
                    6) Turn off the power to the machine and put all the parts back in
                       there place

               Comment : If the U relay works on hydraulics system then the switches are
                         are working right ,also you can check the inputs and outputs
                          signal on your PLC unit

                         Wiring for the new switch on the top of the knife

               The SS,AA,and UL are all wiring points to the terminal, and on the switch.

             Explanation: New switch on the top of the Knife.
                The knife top position switch is a series connection with the clamp top position
             switch, it is a new safety device for the Mark- II Programmatic signal, when the knife
             does not go up to the top position, because of it, the backgauge will not move to the next
             size.

                                                           NOTE: 

                                   New Light Safety Curtain for 660 Cutter 

              The new light safety curtain will not work the older machines, because they do not have a AC 24 V power
        wire fitted, if you would like to mount the new light safety curtain on the older machines you need to connect a 24
        V wire form the transformer, and also you would have to do some modifation to the side tables, in order to mount
        the light safety curtain.

              The light safety curtain will work on machine above the serial number 0104034, and will not work below
        that serial number without doing modifation.


        Important Note: Use discretion when ordering this and any other parts or options. Check the serial number
        of the machine or machines and compare them to the implementation number before ordering this option.

             Fax all parts orders to the Parts Department at (949) 752-7766. If you require further information or
        assistance, contact Duplo U.S.A. Technical Department, Graphic Arts Division at (949) 752-8222.
