Question about Brother LS-2125 Mechanical Sewing Machine

Tension or timing?

I just bought a Brothers sewing machine at Walmart last year. I've only used a few times and it worked great. The thread appears to be jamming under the material. I've tried to adjust the upper tension and nothing seems to be working. I was attempting to sew stretchy knitted pants, so I don't know if that has any affects or not. Even my mother couldn't figure this one out as she use to sew quite a bit in her day. However, I had heard/read there is a timing on the machines. I haven't taken it to a servicing company yet, trying to same money after all....

Could you suggest something?

    I have the same problem. I'm thinking it is the timing on the machine. I bought mine at wal-mart too. That's what we get for buying cheap stuff.

I have my mums old machine is it worth getting it serviced or just get a new one?

Just call in at a sewing machine outlet and ask them for an opinion. A lot of these older machines were very well built with quality bearings, steel gears and powerful motors. It may just need a clean.

My CE5000PRW the wheel well not move and it keeps coming up e6 but it just wont sew... HELP!!!

I think what I would do is totally rethread the machine, make sure that the thread is feeding the right way,(look in your manual, or online, very important, have your presser foot in the up position never down when threading) Now when you have it threaded, pull both upper and lower threads, it should pull through smoothly and be in all guides for the tension. Do not skip any guides. Try this easy fix and I hope that it works for you.

Bottom thread on Juki DDL-5550 is coming up. Top thread seems to lie flat

Check your upper thread at the spool. I've had industrial machines randomly throw a loop around the spool holder spindle which is hidden under the spool itself.

Also check your threading guide to be absolutely certain you are threading it correctly. Also make sure needle/thread diameter are suitable for each other.

Good luck.

Bernina 801 tension problems

When you thread the top thread, be sure to ALWAYS RAISE the presser foot so the thread will seat completely in the tension unit. Your machine is an older metal mechanical machine which makes it last a lot longer than the newer plastic computerized models. However, parts do wear, so perhaps the tension unit has become worn and loose over time and use. If you find you have find you are using a consistently high tension, you may need to have your machine serviced. In addition, slightly increasing the bobbin tension may help balance out the top tension.

Using Janome 8080 for free motion quilting and tension is not working. Tried different threads, needles and tension settings. Sometimes it works for a few inches but then the tension gets really loose on...

check to see if cleaning is needed. Threading and bobbin are correctly done. Could be thread if using a cheap brand. Try Sewer's Aid as a last alternative. That item is great for problem threads.

I have a Kenmore sewing machine - 12 stitch model which I bought in the 70's. I am having a tension problem and can't seem to fix it. What is the normal setting for the top, and bottom?


Load your Kenmore sewing machine with the right thread and bobbin thread for your project. If you use the wrong weight thread for your fabric or severely uneven weights of thread, this can cause the appearance of a tension problem when it is, in fact, a thread weight problem or a problem with your sewing speed. If you go too fast, you will break the thread. If you go too slow, you can cause loops. Uneven pressure can cause stitches to vary greatly.

Test your Kenmore sewing machine's tension by sewing on a piece of scrap fabric. If your tension is way off, then test on some basic cotton or a firm blend simply to get your tension right. Do not try to start adjusting your tension on silk or leather. Get a base adjustment on a more standard fabric first.

Look at the top threads and bottoms threads. If the tension is off on one side, it will usually affect the other side slightly. So select the side that looks more maladjusted to start adjusting the tension.

If the top thread is too loose or too tight, you will need to adjust the tension dial. This dial is usually located a few inches above the needle on the Kenmore machine body. Usually, your machine will have markings to indicate which direction tightens the tension. If these have worn off over the years, watch the dial as you turn it. If it appears to move toward the machine body, then it is tightening.

If the bottom thread is too loose or too tight, then you will need to open the door to the bobbin case. On some Kenmore models, there is a little screw near the bobbin case that can be adjusted slightly to adjust the tension. On other Kenmore models, there is a screw on the bobbin case itself--not on the bobbin, but on the bobbin's casing. This will also adjust the bottom thread tension. Adjust the bobbin thread tension to make slight changes.

If the thread is looping severely on one side, the thread weights might be off. For instance, look to see if you have a lightweight thread on the bobbin and a heavyweight one on the top. If the thread keeps breaking, the top tension or bottom tension could be too tight or the thread is too lightweight for the material you have selected. Check your combination of threads and material. Also make sure you are using the right weight needle and the right foot for the sewing step or project you are working on.

If your Kenmore sewing machine's tension is off severely or if you have not used your Kenmore in a long time, then you might need to take your machine in to be serviced. Sometimes, the inner parts need to be oiled or the entire machine might need to be cleaned and calibrated by a professional. If you sew a great deal or if your machine sits idle a lot, both situations will usually require some servicing to keep your Kenmore sewing machine and its tension in perfect working condition.
