I have problems with my tension settings

I have a tacsew T111-155. I just purchased it a couple of months ago. I am using #69 Nylon bonded thread. It was sewing just fine, then I changed the color I was working with, now the thread is bumpy on the back side. It is very loose. I have played with the tension but, I can not seem to get it right. I have been sewing for many years but all of my machines came with troubleshooting guides which were a big help. The manual that came with my tacsew does not have such a feature. Can anyone give me any sort of feedback as to what might be going on? Is this caused by the bobbin tension or either of the two thread tensions on the top of the machine?
Thanks Everyone

    I own a Brother LS-1217 Mechanical Sewing Machine and the tension is no longer working. After examining the machine it looks like the spring in the back of the tension control is wore out but I can't seem to find a new spring or anyone who can work on it in my area (Louisville, KY). Can anyone offer me some help?

    All of the sudden my machine is looping thread on the reverse side of the stitch.  I cleaned a big dust bunny out from under the machinery, but it didn't help.  I haven't figured out how to adjust the tension on the bobbin and nothing else has worked.

It might be your thread you might have the wrong twist some machine use right twist or left twist .or your needle might not be the in right ..or the wrong size. if your thread is loose on top it your bobbin tension,if it on the bottom it your top tension on your machine.

Your thread may be too large for the machine to use. Try using the highest setting on the tension.

Tacsew t111-155 sewing machine skipping stitches after rethreading and changing needle

I don't have firsthand knowledge of this machine, but the machines I've used would do this when the thread tension was too high. Check the thread path for any dirt or buildup of fuzz from the thread. Also, check to make sure the thread tension adjustment isn't set too tight. Gently tugging on each thread one at a time may reveal which thread is binding and make your search more efficient. I hope this helps.

Sewing 1/4" leather. Bottom thread

You did it backwards!!! Reset the bottom tension to the default position, with heavy threads its touchy to get back to normal. Turn the upper tension about 1 turn clockwise (tighter) and try. No luck, try a turn then test, then a turn, test.....The size of the thread can cause issues as well. We mostly use #69 nylon threads, but the 1541 can use # 69 to 192 without to many problems. look in the book for how to reset the bobbin case tensions. The 1541 is a wonderful machine, much better quality than the chinese junk being sold nowadays.

Hi, This is a threading problem.
When you thread the machine, to make sure it is right in the top tension, thread as far as the take-up lever and stop.
Set the presser foot down, turn the top tension dial to zero, and then to 3 or 5. While turn the dial, pull the thread some to see if it tightens up as the dial increases in numbers.
After the thread comes out of the tension discs, it should then go through the check spring, then up to the take-lever.
The needle is correct and thread from the inside out, meaning right to left.

Hope this helps for now..

Take care

Top thread breaking on my industrial tacsew sewing machine that has been made into a quilting machine

Check threading is correct. If it is, check the tension. Sometimes it easy to misthread the upper thread tensioner. Also using a large spool that takes too much to spin it can have too much inertia and cause thread to break.

Thread breaks off

Where does it break? You change tension at the top via the tension discs the thread passed through, and at the bottom by adjusting the small screw on the bobbin case - the screw on the front part of the spring. Thread size matters as well as needle size. For everyday upholstery I use #69 nylon thread, and "G" bobbins.
If the thread's breaking at the hook you may need to adjust timing. But most commonly thread breaks because of improper tension, threading, needle or thread size.

I answered this a couple days ago but don't know if it went through. I can sew through 6 or more layers of denim with my 226, no problems at all. In my 30 years in the upholstery business I never had a problem sewing leather, vinyl, canvas or multi-layers of fabric. The 226 Consew, the 111W and 211w Singers I had presented zero problems with heavy fabrics - and I don't consider vinyl "heavy".

You need to first of all check threading. If the machine's threaded wrong you're break thread. Also you need to oil under the bobbin case and the bobbin hook and the rest of the parts as well.
Then, loosen thread tension on top by turning the knurled knob that's on the spring that's holding the tension discs. Also loosen bottom tension on the bobbin case by turning the small, left-most screw on the outside of the bobbin case counter-clockwise. Do both with the presser foot down. Pull the thread(s) out and feel the tension. You should be able to pull the threads out with some little effort. Tighten both a little at a time until you get some tension. Run a couple seams and check where the threads meet in the fabric. They should meet in the center. Also check stitch length. If you're using 92 thread (is should be left twist), you should run the machine at about 6 - 7 stitches/inch. I'm running my machine at 5 - 5 1/2 with #69 nylon bonded, and 6 - 6 1/2 with #11 mono.
One more thing; if tension's too loose at the bobbin or top, the machine will jam in the bobbin and thread will break.
Go to and download a pdf owner's manual for free. You need to click on the 224. That machine, the 225 and 226 are the same.

Tacsew T500 : Needle continually comes unthreaded

No this machine does not use a bobbin. I just purchased one too and called the supplier to help me keep mine threaded. He said they do not take much tension at all. So check your tension and then when threading it, make sure your thread goes under the bar in the center of the tension disk, not on top of.
Good luck, once you get it going it does a beautiful job!!!! Love it, Love it!
