  If the upper thread is not being trimmed, it could be due to: * A blunt movable knife; replace it. * A blunt fixed knife; sharpen or replace it. * The movable knife not picking up the thread; adjust the position of the shuttle race thread guide. * Skipped stitches at the sewing end preventing the movable knife from picking up the thread; refer to “Skipped stitches occur”. * An incorrect movable knife position; adjust it. * Sub-tension being too weak; turn the sub-tension nut to adjust the tension.
