Question about Consew 206RB
The top tension cannot be adjusted. When i adjust the top tension spring, the discs the thread goes around are extremely loose. i took it apart and think the problem is because the Tension release lever rod is not pressing against the tension release lever and not adjusting the tension release plunger. how do i get the tension release rod to work properly again?
SOURCE: bottom tension to tight
There's hardly any way to significantly adjust the bottom, or bobbin tension. There's just a small, flat spring attached to the side of the bobbin case, under which the thread runs. There's adjustment there. You need to adjust the top thread tension via the small thumbscrew that's against the plates on the top thread tension discs. Increase or decrease tension there until top and bottom threads are equally centered between layers of material.
You can adjust presser foot tension with the knurled nut at the top of the machine. I never had the kind of problem you mention though. I set my machine at about 6 stitches per inch or a little more (max is 5, recommended), and presser foot tension is only heavy enough to pull a single layer of material through.
Hope this helps.

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.

SOURCE: Top Thread Breaks or shredds
Have you checked to see if the needle and thread are compatible? I use several different sized needles on my machine, depending on the thread and fabric I'm sewing.
Possibly, your machine might need lubrication or service.

Todetermine if your machine's current tension settings are correct, hoop a pieceof cotton with a medium-weight cutaway stabilizer. Stitch a design that has acolumn of satin stitches -- like a letter "I." You should see 1/2 to1/3 bobbin thread on the backside, and no bobbin thread on the front side.
If you see bobbin thread on the top, then your bobbin thread tension is eithertoo loose, or your top thread tension is too tight. Sometimes it is acombination of both factors. Adjust the settings on your machine, and restitchthe design until the balance is correct.
Conversely, if you see no bobbin thread on the backside, that means that thetop thread is too loose, or the bobbin thread is too tight. And, sometimes it'sa combination of both. Adjust the settings on your machine, and restitch thedesign until the balance is correct.
When adjusting the bobbin thread tension, it may be helpful for you to mark the"starting position" with a pen or dab of nail polish. Turn the screw1/4 turn at a time until you have the correct balance. One embroiderer, Joyce,sent in this helpful hint:
Remove the bobbin and casing intact,keeping the bobbin thread in the tension springs. Dangle the casing by thepigtail of the thread. If the casing remains in place and doesn't move, givethe thread a light ****, like a yo-yo, to see if you can get the casing toslide down the thread. If it rapidly slides without stopping, it's too loose.If it doesn't move at all, it's too tight. If it slides a couple of inches andstops on its own, it's just right. Use the corner of a business card to cleanbetween the springs.
If the above does not resolve the problem, then more information is below:
Digitizing of a design does not affect thread tension. Frequent orchronic problems with thread tension are due to incorrect stabilizer, athreading problem on the machine, or a problem in the bobbin area.
First, incorrect stabilizer. Thread tension problems can occur when usingtear-away stabilizer. Tension on embroidery machines is set with the assumptionthat you'll be stitching through two layers -- fabric, and stabilizer. If youare working with a complex design and using tear-away stabilizer, then theneedle perforations will disintegrate the stabilizer during the embroidery.That means that you're stitching through just one layer, and you may findthread tension troubles. If this occurs, try cutaway stabilizer instead oftear-away.
Second, a threading problem on the machine. Always thread the machine with thepresser foot up, and make sure that you're catching all of the guides along theway. If you miss one, you'll have numerous thread breaks as well as tensionproblems.
Third, a problem in the bobbin area. If you've had a thread nest, there may bestray bits of thread remaining in the bobbin area. This may cause a tensionproblem. Open the bobbin area and use a small vacuum (like the kind forkeyboards, or use a flexible straw with a regular household vacuum cleaner) toremove any lint, dust, or stray bits of thread. (We have used compressed airbefore, but some machine technicians recommend sucking with a vacuum ratherthan spraying.)
