  If the thread tension control nut pressure is too strong or too weak, adjust it to an appropriate pressure. If the needle point is broken or bent, replace it with a new one. If the needle and looper adjustment or clearance is incorrect, adjust correctly. Also, ensure the needle and needle guard adjustment is correct. A blunt looper tip can also cause skipped stitches; repair it with an oilstone or replace it.

  If the thread tension control nut pressure is too strong, adjust it to an appropriate pressure. If the thread is of poor quality, use a better-quality thread. If the thread is too thick for the needle, use a different-size needle. If the needle groove or needle hole are not smooth, replace the needle. If the needle and looper adjustment is incorrect, adjust the needle bar height or the looper and spreader height. Damaged components like the needle, looper, or thread path should be repaired or replaced.

  If the knife is blunt, replace it with a new one. If the knife does not move to the full stroke because air pressure is too weak, adjust the air pressure. If the movable knife position is incorrect, adjust the position of the movable knife or the loop spreader.

  If the knife is blunt, replace it. If the knife doesn't move fully due to weak air pressure, adjust the pressure. If the upper thread trimmer knife isn't picking up the upper thread, install it so it cuts only one side of the upper thread loop. If the movable knife isn't picking up the needle thread because the last stitch is skipped, refer to the remedies given under “Skipped stitches occur”. If the movable knife position is incorrect, adjust its position or the loop spreader.

  If the thread nipper spring force is too weak, adjust the force of the thread nipper spring. If the upper thread length is too short after trimming, install the upper thread trimmer knife so that it cuts only one side of the upper thread loop. If the needle and looper adjustment is incorrect, adjust the needle bar height or the looper and spreader height. If not enough upper thread is being fed out, adjust the amount of upper thread being fed out.

  If the cutting pressure is too weak, adjust the cutting pressure so that it is strong enough. If the knife and cutting block are not contacting properly, grind the cutting block surface. If the knife is blunt, replace it with a new knife. If the cutter arm operation time is too short, make the operation time longer by changing the memory switch setting.
