Question about Simplicity Pioneer II SA200 Mechanical Sewing Machine

2 Answers

The top thread continues to break once I begin sewing. I have done all the recommended changes (tension controls, etc.) Everything is threaded correctly. It appears the top thread or the bobbin thread is winding around the bobbin spool holder or looping around the bobbin area and not staying in place while sewing causing the top thread to break. What would be the possible cause of this?

I have 2 singer sewing machines and whenever the thread is breaking like that i find that I have to RE-THREAD the machine sometimes SEVERAL times until I can feel the thread give a little bit while its in there & not breaking! It's very frustrating but just keep rethreading from the beginning where you put the spool on your machine & sooner or later you'll get it right & it will work! GOOD LUCK!

I know you've said you have checked the tensions but that usually is the problem. When you pull on the top thread after it goes through the tension but before you thread it through the needle is there some tension but not so much that it breaks when you gently pull on it? It will be a bit harder to pull it at the point after it goes through the needle but it should have a bit of give there too without breaking.

Also check the bobbin again. Take it out of the machine and examine how the thread is wound around the bobbin. Is it all criss crossed or is it fairly evenly wound? Is it in the right direction and through the tension slot? Now dangle it by the thread while in the bobbin case. It should not just reel out to the floor but should slip a bit with some tension and hang there. A slight **** of the wrist should cause it to release a bit more thread and drop a bit more to the floor. It should allow slip but it shouldn't just reel out fast.

When you reinsert the bobbin case into the machine you should feel/hear a slight click as it catches into place.

Also check the needle though that usually isn't what causes this kind of problem.

The thread will break when it has no 'give'. Either the tensions aren't quite right or it is catching somewhere along the way through the various guides where you thread it. Oh and make sure the spool itself is freely turning on the spindle! Sometimes it is because of catching at that point and simply turning the spool upside down so it can't catch will solve the problem ! :)

My pfaff 1475 CD thread is loopy on bottom and breaks on top.


Look very closely at your sample stitching and determine which thread (top or bobbin) is looping and which is breaking. That will narrow down where the problem exists.

A top thread that loops and makes thread "barfs" under the fabric is generally an upper thread tension problem.
Try: Remove the top thread. ALWAYS RAISE the presser foot and rethread from the beginning. Set the upper tension to the midway point (probably will need to tweak this tension depending on your machine).

Just bought Juki MO1000. Have threaded and re-threaded several times (easy enough) because the lower looper thread (position 1) thread breaks after sewing 4-5 inches. Any ideas?


Yep, 9 times out of 10 when thread breaks, something is not threaded correctly. Also, whenever thread breaks or becomes unthreaded, best policy is to unthread everything and start over from the beginning. Simply re-threading the broken thread will usually not work.

Remove all the thread from the machine. RAISE the presser foot (important to ALWAYS do this so the threads will seat properly in the tension disks).

Rethread totally from the beginning making sure to follow the threading instructions for each thread and that the threads are threaded in the ORDER (ie upper looper, then lower looper, then needles) per the manual. If the threads are not threaded in proper order, the machine will most likely never work.

When threading the lower looper, as the last step, be sure to pull the thread tail over the top of the upper looper mechanism before pulling the thread tails under the presser foot.

If the thread continues to break, make sure the tension for that disk is not set too tight. Loosen it up and see if that makes a difference. Most factory standard thread tensions are around the midway point between the high and low numbers. Then slight adjustments can be made from that setting to tweak the tension result.

3rd needle sews for 5 sec then shows needle breakage but no actual thread breakage. If you restart machine it repeats same process, how can I solve problem?


Hmm, I'm wondering if maybe the thread on that needle is hanging up on something or the tension is too tight. Sewing for a few seconds and then breaking sounds like the thread is tightening and then breaking the needle.

The BEST recommendation I've ever read is, if the machine is not serging properly, the thread breaks, or pulls out of the needle: Remove ALL the thread, RAISE the presser foot, and rethread every thread from the beginning. Make sure you are threading in the proper order (it will most likely never work if the step-by-step threading process is not followed!). When threading, grasp each thread below the thread tree and with the other hand grasp it below the tension disk and give it a little tug to make sure it is seated in the tension disk.

Set all the tension dials to the midway area between the high & low numbers and retest.

Changing that needle to a heavier needle may also help although some sergers recommend not using a needle larger than a size 90/14.

HINT: Be sure you are frequently oiling your serger. Because they sew much faster and create a lot of lint, it is important to keep them lubricated, ie once every garment. And be sure to use oil recommended by the manufacturer.

Model 820ex. Why does it have thread nesting, thread breaking, and uneven tension?


You might try cleaning the tension disks by dampening a length of pearl cotton with rubbing alcohol, open the tension disk all the way, raise the presser foot, and then pull the pearl cotton down between the disks a couple of times.

Clean away the lint and thread pieces from the feed dogs and bobbin area. Oil your machine according to the instruction manual--use only fresh good quality sewing machine oil--only 1 or 2 drops of oil each place.

Install a brand new needle. Make sure you are using a needle and thread that are compatible with the fabric you are sewing--that the thread is not too big for the needle's eye, etc.
All About Needles

Make sure you RAISE the presser foot BEFORE threading the upper thread. Rethread the thread from the beginning checking that thread is not wrapping around the spool pin or catching somewhere in the threading sequence.

Verify that you are threading the machine correctly. Misthreading will cause havoc and frustration!

Do not use old or bargain bin thread--Coats & Clark does create problems for some machines.

You might try pulling the bobbin thread to the top before beginning to sew. This helps prevent some of the thread nests you are experiencing.
How and Why to Bring up the Bobbin Thread

The factory tension setting is usually the halfway point between the high and low number. This is where you should start testing your tension. Once you sew a sample, if the top thread is looping/knotting (bird nesting) under the fabric, the upper tension is most likely too loose. If the bobbin thread is pulling to the top of the fabric, the upper tension is too tight. Get used to adjusting the upper tension every time you change fabric, needle, thread. The upper tension is not meant to be static, so don't be afraid to adjust to achieve the proper tension.

Ideal tension is when both the upper thread and bobbin thread meet in the middle of the fabric.

Thread keeps breaking


Here are a few sites that may be helpful in diagnosing your problem:

NUMBER ONE SUGGESTION--install a brand new needle. Sewists are known to be very frugal about changing needles but it is usually the easiest and least expensive fix for a lot of problems.
Remove all the thread from your machine, clean the bobbin area of any lint, threads, etc. Be sure that you RAISE the presser foot BEFORE you thread the upper thread. This releases the tension disks so the thread will seat properly. Now, re-thread from the beginning verifying you are following the correct threading sequence (consult your manual).

The standard factory tension setting is the midpoint, ie of the range is 1-10, set the tension at 5 and then adjust from there.

My serger will only sew a few inches, then the thread on the lower looper breaks. I have checked threading, rethreaded many times.


Been there, done that. Old serger almost went out the window more than once.

Raise the thread antenna and loopers to their highest positions.

Set the tensions to zero. If your serger has auto-tension, raise the presser foot as this also opens the tensions.

Begin threading from the right as indicated in your manual or on the door of the serger.

If this continues, the serger may need to be serviced as the timing could be the problem.

Ask before leaving the serger as the service cost usually starts around $100.

I finally gave in and bought a Babylock with instant jet-air threading.
