Question about Brother LS-2125 Mechanical Sewing Machine

1 Answer

Tension doesn't seem to work at all. I cleaned the bobbin cases and the whole machine inside, oiled it, made sure it's threaded correctly--and the tension is still completely messed up. Turning the tension dial doesn't make any difference--the sttich doesn't change regardless of what number it's on. It's very loose.

Brand new machine, do I need to oil it? singer talent 3321 is suppose to be EASY...needle broke, now it will not sew, seems to be stuck and bobbin seems to not work.


1. You need to remove the bobbin case and adjust the tension. The tension should allow the thread to move with a slight tension. Clean the area with a qtip. The bobbin case sits in a an area that is called the race. The race needs one drop of oil. Replace everything.
2. Replace the needle. Make sure it is in the right direction. Thread the top while the foot is up. If the thread gets stuck while threading there is a problem. The thread should move easily while the foot is up. After you thread the machine except the needle you can put the foot down. Now pull on the thread. It should give you a slight amount of tension. Usually four is a good number. If the tension is too tight you can adjust as needed. Now, thread the needle. Hold the thread under the foot while you turn the hand wheel. The bobbin thread should come up.
3. Give your machine a try with a slow speed.

I am not sure about this particular machine but in most machines there will be a nob on the front loose low numbers like 0 1 -2 work well on number 3. If the nob is not on the front check and see if it is on the side.

I have a faithful 730 Bernina and currently the bobbin thread keeps breaking. Please advise what may be causing this. Thanking you.


Bobbin thread breaks
1. There is a right way & wrong way to insert the bobbin in the case --when you insert the bobbin in if it doesn't stitch correctly turn the bobbin over see if that helps or bobbin case is not inserted correctly
2. Lint has collected in the bobbin holder
3. The bobbin is damaged & doesn't turn smoothly
4. Lower thread tension is two tight

here's a free manual

New Home ss2015 machine. I am having trouble with the thread tension. I have loops on the bottom. I have cleaned the bobbin case, changed the needle, re-threaded and moved the upper tension all the way up....


try adjusting the top tension to 3 & if it doesn't stop the looping, try 4 but I wouldn't go any higher than 5,, if changing the top tension doesn't help then I suggest taking the machine in to have it serviced. the bottom tension is more difficult to do,, it's also very possible that the top tension dial is messed up & needs replacing. only a sewing machine shop can tell for sure.

Tension


I'm assuming the thread is looping on the bottom. If this is not the case, ignore the rest of this.
Perform a tension test. Tension assembly test. To do this test. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.)
If it doesn’t work this way then you probably have a piece of thread or lint stuck inside the tension discs. To remove it, turn the tension to 0 zero and raise the presser foot.Using a small screwdriver, open the space between the discs and spray with canned or compressed air. The stuff should come out. Do the tension test again to make sure you got everything and then try sewing again.

Help! Tension Problems


Looping on the top means there is no tension on bottom. The bobbin thread generally rotates counter clockwise. The thread must get under the tension spring. The spring must be adjusted equal to the top tension. This you will have to play with to tighten or loosen as needed. When you sew in a zigzag you might want to loosen the top tension slightly. On a regular basis remove the bobbin case and clean with a qtip. On the race put one drop of sewing machine oil. Clean the bobbin case and replace.
