All portable sewing machines are used to sew (woven bags, composite bags, thin gunny bags). The steps in use are as follows:
1. Put the products needed to sew the bag into the feeding teeth.
2. Press the start switch and the feeding teeth will move forward automatically.
3. When sewing to the end of the bag, lead the thread into the cutter and press the start switch to complete thread cutting (at present, there are kg9-88, kg9-88s, kg9-836, F1, F2 and F3 sewing machines with automatic thread cutting function). Others don't know whether to take this function.
