Newland DS-9C Sewing and Packing Machine
Thread Content
The DS-9C sewing machine sometimes breaks the thread for no apparent reason; the hook needle and the straight needle do not touch each other, and there is no wear on the needles. The bottom thread and the auxiliary thread are neither loose nor tight. What’s going on? What needs to be adjusted? Does anyone understand? Thank you in advance for your guidance, sir
The wire compressor is too tight; loosen it a bit.
Also, check to see if the positions where the thread passes through are all correct.

How do I adjust the hook eccentric in the DS-9C seaming machine to a 45-degree angle? I find the instructions a bit hard to understand. Is there anyone who can give me some guidance? I’d be very grateful: handshake
