1. Excessive kneading of the noodles by the noodle machine leads to insufficient strength. Flour with good gluten texture should be selected to reduce kneading time.
2. The adjustment of the noodle machine is too tight. The small screw of the gear lever of the noodle machine should be loosened appropriately to adjust the appropriate fit of the noodle machine.
3. The blade is worn and needs to be replaced.
