  • EEP-ROM in addition to the floppy disk can be used.
    1) Data ROM is mounted on U23 located on the MAIN circuit board. In addition, confirm that the switch is ON the switch on the [256] side. Part No. of ROM : HL011940000 (EEP-ROM, 58C256)
    2) When the data ROM for the AMS-206 is used, change over the switch located on the circuit board to the [64] side.

  • Neben Disketten kann auch das EEP-ROM verwendet werden.

1) Receding position of the presser (application of the 2nd origin)

Ther is a case where the preser is slanted and the material is hard to be set in accordance with the material. In this case, it is easier to set the material if the 2nd origin is set to near-by the center of the presser.

In case where the lift of the feeding frame is high, the feeding frame is likely to come in contact with the intermediate presser. In this case, it is recommended to set receding position of the presser (2nd origin) described in item 1) and to make a recess for the intermediate presser in the feeding frame blank.

Note) The input device is necessary when creating the sewing pattern.

By changing DIP SW1 1, DIP SW2 2, and SLIDE SW3 3 mounted on the control box, the setting can be changed as described in the following table. (Caution)

  • Perform the change of the DIP SW and SLIDE SW after turning OFF the power switch.
  • Do not turn ON the switch not used yet.

5. Troubles and corrective measures (Sewing conditions)

TroubleCauseCorrective measuresPage
1. The needle thread slips off at the start of bar-tacking.① Stitches are slipped at the start.2 The needle thread remaining on the needle after thread trimming is too short.3 The bobbin thread is too short.○ Adjust the clearance between the needle and the shuttle to 0.05 to 0.1 mm.○ Set soft-start sewing at the start of bartacking.○ Correct the thread tension release timing of the thread tension controller No. 2.○ Increase the tension of the thread take-up spring, or decrease the tension of the thread tension controller No. 1.○ Decrease the tension of the bobbin thread.○ Increase the clearance between the needle hole guide and the counter knife.595931-323163
2. Thread often breaks or synthetic fiber thread splits finely.① The shuttle or the driver has scratches.② The needle hole guide has scratches.③ Fibrous dust is in the groove of the shuttle race.④ The needle thread tension is too high.⑤ The tension of the thread take-up spring is too high.⑥ The synthetic fiber thread melts due to heat generated on the needle.○ Take it out and remove the scratches using a fine whetstone or buff.○ Buff or replace it.○ Take out the shuttle and remove the fibrous dust from the shuttle race.○ Reduce the needle thread tension.○ Reduce the tension.○ Use silicone oil.3132224
3. The needle often breaks.① The needle is bent.② The needle is too thin for the material.③ The driver excessively bends the needle.④ Feed trimming is excessively slow.○ Replace the bent needle.○ Replace it with a thicker needle according to the material.○ Correctly position the needle and the shuttle.○ Make the feeding timing fast.2760
4. Treads are not trimmed.① The counter knife is dull.② The difference in level between the needle hole guide and the counter knife is not enough.③ The moving knife has been improperly positioned.④ The last stitch is skipped.○ Replace the counter knife.○ Increase the bend of the counter knife.○ Correct the position of the moving knife.○ Correct the timing between the needle and the shuttle.6359
5. Stitch skipping often occurs.① The motions of the needle and shuttle are not properly synchronized.② The clearance between the needle and shuttle is too large.③ The needle is bent.④ The driver excessively bends the needle.○ Correct the positions of the needle and shuttle.○ Correct the positions of the needle and shuttle.○ Replace the bent needle.○ Correctly position the driver.5959589
6. The needle thread comes out on the wrong side of the material.① The needle thread tension is not high enough.② The needle thread after thread trimming is too long.○ Increase the needle thread tension.○ Make the feed timing slow.○ Increase the tension of the thread tension controller No. 1.316131
7. Threads break at time of thread trimming.① The moving knife has been improperly position.○ Correct the position of the moving knife.63
8. When synthetic fiber thread is used, at the start or end of sewing, needle thread rises or remaining of needle thread is excessive.① In case of synthetic fiber thread, the thread is harder than other threads and penetration resistance to material is small.○ When making a pattern, set the sewing pitch at the start and end of sewing to 1 mm or less.

Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of the sewing machine.

WARNING :

When synthetic fiber thread is used, fix silicon tank 1 (B92118500A0) with setscrew 2.
