2 Toe down the pedal and check the backtacking performance as sewing begins.<br />
Figure 2<br />
3 If the backtacking performance is unsatisfactory, reinsert the fabric underneath<br />
the presser foot, and adjust the number of stitches in the parameter A02 setting<br />
so that, at a low sewing speed, the edge of the fabric moves beyond end A of the<br />
stitch plate tongue (in the ⇒ direction; refer to figure 2) and then the thread<br />
chain clamp moves to the right. (See figure 3.)<br />

separately.)<br />
3 If the backtacking performance is unsatisfactory, reinsert the fabric underneath<br />
the presser foot, and adjust the number of stitches in the parameter A02 setting<br />
so that, at a low sewing speed, the edge of the fabric moves beyond end A of the<br />
stitch plate tongue (in the ⇒ direction; refer to figure 2) and the thread chain<br />
clamp (right) opens (thereby releasing the thread chain). (See figure 4.)<br />

9. Troubleshooting Q&A<br />
Q A See<br />
1<br />
• The thread chain (soft<br />
chain) condition is<br />
unsatisfactory.<br />
• Have any errors been made in the threading?<br />
• Is the stitch plate or any other part damaged?<br />
• Is the speed at the end of sewing set to high-speed<br />
operation?<br />
(The timer C02 setting must be faster than the C01<br />
setting.)<br />
(The timer C03 setting must be ON.)<br />
Refer to section 7.<br />
2<br />
• The thread chain is not<br />
blown back and caught<br />
properly.<br />
• Have the speed controllers been adjusted correctly?<br />
(Check the speed controllers A, B, C and D again.)<br />
• Has the K2 device been installed in parallel with the<br />
stitch plate?<br />
• Has the K2 device been installed correctly in terms of<br />
its front-back postion?<br />
• Increase the operating time for timers B04 and B05.<br />
Refer to section 9.<br />
Refer to section 10. Refer to<br />
section 5.<br />
3 • Defective back-tacking<br />
• Does the thread chain clamp move toward the right<br />
too early?<br />
• Does the stitch plate tongue move forward too early?<br />
(Timer B09, B10)<br />
• Adjust the tighten/loose timing of the tension releaser<br />
for the material. (Timer B06, B07)<br />
• Check the thread chain condition.<br />
Refer to section 8. Refer to<br />
section 6. Refer to section 5.<br />
Refer to section 7.<br />
* Checking the timers according to the sewing to be performed<br />
