1. Make sure the sewing machine is turned off. Find and adjust the automatic thread trimmer. Usually, the automatic thread trimming regulator is located above or below the sewing machine, and a small iron piece or knob can be observed.
2. Adjust the position of the automatic thread trimming regulator. If the sewing machine is too short or too long when cutting thread, you can try to adjust the automatic thread cutting regulator to a suitable position. Generally, adjusting the adjuster to the right or up will make the trimming longer, and adjusting the adjuster to the left or down will make the trimming shorter.
3. After adjustment, restart the sewing machine for testing. You can observe whether the length of trimming has been adjusted to the ideal state.
4. If there are still problems after adjustment, you can further check other parts of the sewing machine. For example, check whether the line passes through the clamp correctly or whether the blade is sharp.
5. If the above steps fail to solve the problem, it is recommended to consult professional maintenance personnel or contact the manufacturer for after-sales maintenance.
Different models of sewing machines may have different automatic tangent adjustment methods. The above steps are for reference only. Before adjustment, it is recommended to read the instructions carefully or consult professionals to avoid unnecessary damage to the machine.
