When adjusting, first pull up the machine head, loosen the screw of the lifting crank, and then gently lift the bracket with a screwdriver to make the feeding teeth face.
Only 0.8-1 mm of the needle board is exposed. It is the standard size of the tooth height. As long as it is adjusted to this position, the cloth can move normally. Finally tighten the screws. When screwing the screw, the machine head must also be pulled up.
