Why is my Toyota Sewing Machine not working?

  Jonathan HansonAug 16, 2025
  Your Toyota Sewing Machine might not be working because the power plug is not correctly inserted. Ensure that the power plug is properly connected. Also, check if the main power switch is turned off and turn it on. Another reason may be that the thread is tangled in the hook, or there is a broken needle in the hook; in this case, you should clean the hook. Finally, check if the thread winding spindle has been pushed to the right, and if so, push it to the left.

Why is the upper thread on my Toyota Super J34 Sewing Machine keeps breaking?
- A
  Adrian ShortAug 19, 2025
  The upper thread of your Toyota Sewing Machine may keep breaking because the machine is incorrectly threaded; in this case, rethread the sewing machine. The thread might be tangled in the bobbin case or hook, so remove the thread tangle and clean the feed dog and hook. If the upper thread tension is too tight, loosen it. Also, the needle could be bent or the needle point is burred, so insert a new needle. Check if the needle is incorrectly inserted and correct it. Finally, the thread may be of poor quality, so use a good quality, recommended thread.

  If the needle keeps breaking on your Toyota Sewing Machine, it might be due to several reasons. Ensure the needle is correctly inserted into the machine. Check if the needle clamp screw is loose and firmly tighten it. The needle might be too fine for the fabric, so use the appropriate size needle for the fabric. Also, the upper thread tension could be too tight, so loosen the upper tension. Lastly, ensure the bobbin case is in the correct position.

What to do if fabric is not feeding through my Toyota Super J34 Sewing Machine?
- D
  Dawn CohenAug 26, 2025
  If the fabric isn't feeding through your Toyota Sewing Machine, there are several potential causes. First, the feed dog might be dirty, so remove any lint and fluff from it. Second, check if the pattern selection dial is set to a buttonhole number (“2” or “4”) and reset the stitch selection dial to the desired stitch. Also, the feed dog might be lowered, so raise it. Ensure the stitch length dial is not set to “0”, and if it is, adjust it. The stitch length might also be too short, so adjust the stitch length dial to an appropriate setting. Finally, the presser foot pressure could be too light, so increase the presser foot pressure.

  Missed stitches on your Toyota Sewing Machine can occur for several reasons. Ensure the needle is correctly inserted. If the needle is bent, use a straight needle. The needle and thread may not be suitable for the fabric, so use the correct needle and thread for the fabric. Also, check for incorrect upper threading and rethread the upper thread correctly.

Why is the lower thread showing on the top of the fabric when using my Toyota Sewing Machine?
- A
  Angela WebbAug 31, 2025
  If the lower thread is showing on the top of the fabric when using your Toyota Sewing Machine, it could be due to incorrect bobbin threading, so rethread the bobbin correctly. The tension of the upper thread might be too tight, so adjust the thread tension. Also, ensure you are using the correct plastic bobbin and not a metal bobbin; only use the designated TOYOTA bobbin.

  If the upper thread is showing on the under side of the fabric with your Toyota Sewing Machine, it could be because the tension of the upper thread is too loose, so adjust the thread tension. Also, check for incorrect upper threading (not threaded through the thread guide) and rethread the upper thread correctly.

Why does the fabric wrinkle or pucker when using my Toyota Super J34?
- V
  valerie57Sep 6, 2025
  If the fabric wrinkles or puckers when using your Toyota Sewing Machine, it could be because the tension of the upper thread is too tight, so adjust the thread tension. The machine might also be incorrectly threaded, so rethread it. If the needle is too thick for the fabric, use a finer needle to suit the fabric. A burred needle can also cause this, so insert a new needle. If you're sewing stretch fabric, use the ballpoint needle.

Why am I unable to sew stretch stitches on my Toyota Super J34 Sewing Machine?
- E
  emily64Sep 9, 2025
  You might be unable to sew stretch stitches on your Toyota Sewing Machine if the stitch length dial is not set to setting “A – K” or “L – S”, so set the stitch length dial to the appropriate setting. Also, the stitch length dial and the stitch pattern selection dial settings may not correspond, so select the same setting on both dials.

What to do if the needle cannot be threaded with the needle threader on my Toyota Sewing Machine?
- D
  Danielle PhillipsSep 12, 2025
  If the needle cannot be threaded with the needle threader on your Toyota Sewing Machine, the needle position might be too low, so turn the handwheel so that the line is at the top. If you are using needle no. 9/65, use needle sizes 11/75 to 16/100 instead. Check if the needle is incorrectly inserted and correct it. If the needle is bent, use a straight needle. Also, ensure the threading of the needle bar thread guide is correct and rethread it if necessary.
