What causes the lower thread to not cut on a Brother Sewing Machine?
- E
  Evan TaylorSep 8, 2025
  If the lower thread is not being cut on your Brother Sewing Machine, it could be due to a blunt movable knife, which should be replaced. The movable knife might not move to the full stroke because the air pressure is too weak, so adjust the air pressure. Also, the movable knife position might be incorrect; adjust the position of the movable knife or the thread handler. Finally, the cutting pressure for lower thread trimming might be too weak, so adjust it to an appropriate level.

Why is my Brother RH-9820 not cutting material cleanly?

  If the material isn't being cut cleanly by your Brother Sewing Machine, it might be because the cutting pressure is too weak; adjust it to be stronger. Another reason could be that the knife and hammer aren't contacting properly; in this case, grind the hammer surface. Finally, the knife could be blunt, requiring replacement.

  If the upper thread isn't being cut, consider these potential solutions: * Replace the upper movable knife if it's blunt. * Adjust the air pressure if the knife isn't moving fully. * Ensure the upper movable knife picks up only one side of the upper thread loop during installation. * Address skipped stitches, as this can prevent the knife from picking up the thread. Refer to the remedies given under “Skipped stitches occur”. * Adjust the position of the upper movable knife if it's incorrect.
