Problem Reason(s) Solution
Stitching Problems
Stitch is dropping (comes sometimes, then drops again…) Thread Tension (P.No. D113 / 117) is either too loose or tight, so looper (P.No. D 300 ) is not catching the Thread.  Adjust Tension spring to give the stitch.
Needle / Looper need to be changed - they may be worn out. Check procedure for Needle/ Looper fitting (Section 4) & fit new ones. 
Needle / Looper timing is not matching. Set the timing between Needle / Looper to give stitch. Check Section 5
Threading is not done properly. Check threading instructions in Section 1, "Machine Installation") 
Stitch is loose on the bag. Thread Tension is too loose. Tighten Thread tension, so thread passes little tightly.
Thread is breaking. Thread Tension is too tight. Loosen thread tension, so that that thread passes.
Stitch dropping only at Bag End. Needle / Looper timing is out. Check Needle / Looper or fit both new pieces.
Stitch not coming at all. After threading machine, a bag or some material needs to be fed into the machine for the stitch to come. Put the bag or or any cloth or material for the first time, near the machine mouth & press switch. The machine will catch the bag & start stitching. Once the stitch has started, it will come even without any bag.

Problem Reason(s) Solution
Bag Problems
Bag is tearing in the middle or at the end, during stitching. Feed Dog teeth (Part No.D203) Feed Dog pressure on bag, needs to be reduced. Adjust Feed Dog by locking screws No.HD64038 on the top of the feed carrier block under the Feed Dog.
Bag is not moving ahead - or not moving fast. Feed Dog teeth are worn out - due to use (wear & tear). Change Feed Dog - as it is worn out.
