Question about Brother LS-2125 Mechanical Sewing Machine

3 Answers

Timing I believe my timing is off because when I go to sew fabric, the spool thread gets all looped up where the bobbin is. It does not correctly grab the bobbin thread, so I end up with a loopy tangled mess around the bobbin area. Any suggestions on timing?

Re: Timing

This happens to me and when I look at my bobbin, the thread is coming out the side instead of the top of the bobbin case where I threaded it - like it came out. When I put it back it will work, but then it happens again adventually. I think I am not threading it properly.

Re: Timing

Question: How does one find the tension discs??? I have a White 1740 with a top drop in bobbin and I went thru the same problems as night_wolf above, then, ultimately, the top thread will now not pick-up the bobbin thread through the fabric. It picks up the bobbin thread without fabric in play, but once fabric is added (for free motion quilting) it won't pick it up. This is after using the machine for the last 10 days to piece and quilt without a problem until this morning.

I'm at a loss.
Tks, Candace

Bobbin tension and thread continously breaking. seems as if cotton is making loops and hooking itself somewhere by bobbin casing while sewing.

The needle/hook could be out of time. First, make sure you are using a brand-new needle.

If you can open the bobbin mechanism and hand-rotate the handwheel, watch the needle/hook action. You may see the problem as it occurs. (There are many web sites and videos online re sewing machine timing.) There could also be a burr/nick somewhere that is catching the thread. Check that the thread is not catching on the thread spool or somewhere in the thread path. Also, verify that it is threaded through all the thread guides correctly. Sometimes the thread will "jump" out of a guide or loop around one causing problems.

Rethread from the beginning--first raise the presser foot to insure the tension disk is released to allow the thread to seat properly. Check that there are no threads, gunk, or lint stuck in the tension disk. Also, clean the bobbin area and feed dogs of any accumulated thread/lint.

There is also a possible problem with needle/thread/fabric incompatibility. Avoid old or bargain bin thread. Make sure the needle is the correct type for the thread, ie the needle eye is too small for the thread, causing the thread to shred and eventually break.

Could also be that the tensions are set too tight.

Every time I try to pick up the bobbin thread, after I use it somehow the thread leading from the bobbin is getting cut and I have to rethread the machine every time.

Basic Tips for All
  1. Always turn the handwheel TOWARDS you (counter clockwise) as turning it in the opposite direction (away from you, clockwise) may knock the timing out requiring repair from a service center.
  2. Always be sure your presser foot is in the DOWN position before sewing. Sewing with the presser foot in the up position will cause your thread to tangle and your bobbin to jam.
  3. Change needles regularly (after 16 hours of use) as dull/weak needles can cause damage to your machine and fabric. Only use SINGER needles on your SINGER sewing machine.
  4. Always be sure you are using the correct bobbin for your machine. Class 66, Class 15 and Class 15J bobbins look very similar. However, using the incorrect bobbin class in your machine can cause damage.

How do I adjust tension on a Necchi Lydia 510 sewing machine?

loops under fabric means top tension needs to be tightened
try cleaning the top tension dial with some unwaxed dental floss and see if that helps. if it doesn't then the tension dial may need to be replaced
also check to make sure the spool of thread is not getting caught on the spool holder
also try a new needle--one that is correct for the fabric being sewed

When I sew, the stitching is loose with large loops on the underside of the fabric making the bobbin thread slide out easily. How do I fix that?

Lift the pressue foot off the fabric. Hold the thread spool with one hand and lightly pull the thread hanging out the back of the needle. This should seat the tread into your top tension discs properly. Now try sewing again. If it still throws loops, you either do not have your machine threaded correctly or your tension on top is set to zero.

Have you tried a new needle? Needles should be changed out before each project and if a large project, several times during the project.

My Husqvarna diamond top thread keeps breaking while doing loop embroidery. It sews a couple of stitches and then you can hear when the thread breaks. Ive tried changing the needle and bobbin, and cleaning...


Primary causes of upper thread breakage:

-- misthreading: pull all the thread off and thread again, using the manual, step by step. Read each step aloud before you do it. (sounds dumb, but helps.) (And make sure you thread the takeup lever!)

-- thread has wrapped itself around a thread guide or spool pin from one of the breaks. Take the spool off the machine before rethreading.

-- bad or damaged needle. Replace with the right size for the fabric, turned correctly (backwards needles skip stitches)

-- dirty machine, especially in the bobbin case area: review cleaning instructions and do it, using brush and vacuum only

-- bad/cheap thread: should not be slubby or break easy. Try another spool.

-- top thread tension too tight. 4 is normal for most fabrics, most stitches.


1) do a light cleaning (brush and vacuum) every day you sit down to sew.

2) replace the needle if you hear it hit metal, if you've got a really bad thread jam, if you see it deflect as you sew (for instance, sewing over the side seam on jeans when hemming). Replace every 3-8 hours of actual stitching time anyhow.

3) buy good quality thread

4) when your machine isn't sewing right, stop; take all the thread off of/out of the machine (bobbin out of bobbin case, spool off spool pin) and give it a quick cleaning. Rethread from scratch, carefully. If that doesn't fix it, do it again, then replace needle and rethread one more time, manual in hand (yah, even if you've threaded it 8 million times before). #4 is curative about 98% of the time. The other 2% often requires professional attention.

How do i thread my needle with the singer handy stitch?

  1. Loosen needle screw & insert needle with shank's flat side facing front of machine. Push needle in all the way, then tighten screw to hold needle in place.
  2. Install a fully wound bobbin by loosening bobbin nut & placing bobbin on top. Re-attach bobbin nut & tighten. If standard thread spool will be used, then attach spool pin to bobbin shaft & place thread spool onto shaft. Attach white spool cap on end of thread spool, then tighten. Bobbin/spool should unwind facing forward toward needle.
  3. Bring end of thread through thread guides & over tension control. Pass end of thread through needle eye, from back to front, & pull it out about two inches.
  4. A spring pushes pressor foot onto fabric that is being sewn, so lift pressor foot & place fabric underneath.
  5. Turn large handwheel on side of machine (handwheel can be turned in either direction) to raise needle arm to its highest position.
  6. Holding the Handy Stitch in place with your right hand, press on power switch & begin sewing. Guide fabric (being sewn) with your left hand.
  7. To end this sewing session, turn off power. Turn handwheel to raise needle to its highest position. Carefully pull out about three inches of thread through needle & snip, then lift pressor foot to remove fabric. Turn fabric over & loop needle threader through last stitch. Place end of thread from underside through eye of needle threader, & pull to loop through. Pull to tighten and snip end of thread.

Bobbin thread loops

If you threaded the machine with the presser foot UP and the thread from the bobbin is feeding from the spool in the correct direction and through the guides on the bobbin case and the loops are still forming, then the machine needs to go into the shop as the timing may need to be adjusted and this is best done by a sewing machine technician, preferably Brother.

No matter which direction I turn the tension, I have big loops

If you threaded the machine with the presser foot up and the is bobbin inserted so the bobbin thread is feeding from the bobbin spool in the correct direction and through the guides as indicated in the manual, then there is a possibility that the timing needs to be adjusted by an authorized Brother tech.

Can't pull thread from spool

The sequence of setting up of thread from spool to needle is not complied to actual setting is one factor to be consider it affect the sequence timing of sewing.Particularly some machine are common in starting up threading.fig. shown a basic flow of thread on red color.It maybe a helpful oneb1934dc.jpg

In addition to this the set up of thread to bobbins winder is also need in right place the thread should be in clockwise rotation when coming out to bobbins casing as shown in fig.76e4431.jpg as you can see when thread was pulled out from bobbins winder is moving counter clockwise.If you try to sew, try cotton fabric and set dial to # 3 to 4 and stitch set range to 8 up to 12 depend on layers and thickness,After setting try to sew manually ,turn hand wheel by your hand first,let upper tension catch the lower bobbins tension and arranged thread and insert fabric use hand turning hand wheel several time until stich appear on fabric observed loop thread on lower bobbins on fabric.if accumulation of loop thread on lower adjust upper tension also dial tension gradually until it has a smooth stich appear.
