Question about White Sewing Speedylock 1600 Mechanical Sewing Machine

Open Question

My serger threads jam around the needle in the throad plate. Looks like it might be slightly bent up. Anything I can do?

Everything has been threaded properly, new needles put in but the threads just keep jamming up on the throat plate needle. It does look like it might be bent up a wee bit, but I'm not sure. Any ideas?

Did you change to the narrow stitch finger? The narrow one is in the door of the machine where the other tools are -- a little square box on the left of where the needle box slides in. Sometimes that is needed instead of the normal one.

Caution: If you have never before changed it out, open the left door all the way and look and see where the stitch finger is coming out of before you remove it all the way. Refer to your manual.

Could be as simple as poor quality thread (not using MaxiLock thread), the needles not inserted properly (the left is slightly higher than the right), a missing stitch forming pin on the needle plate, the needle bar being too high or a looper timing issue.

As the needles raise, the upper looper should move to the right with the right needle tip slightly above the eye of the looper.

Is a bent stitch plate bent back to shape on a Bernina 1150 Serger a good repair?


Probably not. It is doubtful whether you could get it straight enough to meet factory specifications!

I have a bernette 134 and the tread keeps breaking , the lower loop thread , no matter how I set the tension , upper or lower this thread keeps breaking , HELP


Serger thread breaks

1. Is the serger threaded correctly?

2. Is the needles inserted correctly?

3. Is one of the needles bent or damaged?

4. Is the tension adjusted too tightly?

5. Is the tension adjusted to accommodate thickness of thread being used?

6. Are you using inferior quality thread?

7. Is the thread feeding of the cone/spool freely?

8. Is the needle size correct for the type of fabric being used?

9. Are the needles being used the correct one for the serger?

10.check in the needle plate area to see if there is a burr

11. Check the looper to see if there is a burr or if it looks damaged


If all of the above suggestions don't help then the serger needs to be checked to see if there is something wrong with the loopers and also see if there is a problem with the tension.

I have been chaging my serger to overlock for the purpose ofdoing rolled overedge. Rethreaded numerous times, have read the instructions many, many times, setting tensions, etc. I cannot get it to even...


How frustrating, I've tried to find a manual on this model so I can see how you make the change to the thread finger on the throad but couldn't see one. So, I'll go through the set up for 3 thread rolled hem on mine, it probably won't be identical but it might help.

First, remove thread from left needle and remove the left needle from the holder leaving just the right hand needle in place. Most sergers have two seperate needle screws so this can be done but as you mentioned, recheck again that the right needle is right up into the housing as high as it will go. I presume you are using a fresh smaller size needle, especially if this is on a fine or lightweight woven like organza, I'd put in a size 70. If a mid weight then size 80.

Now there should be a thread finger on the foot you change with your screwdriver. Or a little switch you flick so that the throat plate is a different shape to form the narrow seam. Your manual should have this step.

Now if you have some, put wooly overlock thread into your top looper, I cut the thread about 10 inches above the tension dial, put the new spool on, knot it to the existing thread tail, turn tension to zero and pull it through and through the looper eye.

At this point, you should have the two looper threads loose, lift the pressure foot and pull these two threads under the foot and out the back. Turn tension back to about 3 on top looper and tighten up lower looper to 5 or 6 and leave needle at 5.

Adjust blade to cut quite wide, ie wind it to the right side. Now thread the right needle and pull this thread out the back too. Lower the pressure foot, introduce a piece of fabric in under the foot, press the pedal and start trimming and chaining off.

You should have a chain stitch happening now - if not, recheck your threading, particularly the needle, sometimes the thread looks like its in the needle eye but is hooking around the looper. If you still can't get any joy, then it is possible that the timing is just slightly out and this is affecting this stitch. You could try setting up for a normal three thread seam and see if this chains okay.

If you are getting a chain happening now, then adjust down the stitch length to make it denser so it is covering the fabric and check the underside, adjusting top and bottom looper tensions so the thread is enclosing the fabric end rolling to the underside and covering any little fibres.

I hope this is of some help - however, if it still isn't giving you a chain, it could be the timing is out in which case, unfortunately service time.

I have a singer 14sh654 serger. Having trouble with the left needle thread tension disc, it seems to be stuck. Even when it is at 0 and presser foot up there is still too much tension on the thread. ...


Try cleaning the tension discs with a thicker piece of the thread knotted 3 or 4 times and running it back & forth through the discs because there could be lint stuck in there. You should do this at least once a month, alot of threads leave lint behind. Also, check your diffential, put it to neutral. If, that does not help, take it in for service before something breaks off.

Problem with thread allways breaking. think its something to do with the block that the needles are mounted in. the block is at an angle instead of inline with the the machine. which then puts the two...


Most sergers on the market have needles that decend on an angle. Only a few are not made that way. Don't try to straighten it, the rest of the machine is designed with that "slant" in mind. Breaking thread in a serger can be many different things. Here are a few simple checks:
1. Change the needles
2. Make sure the thread is pulled deep into each tension unit, sometimes the thread will "ride" on the outside of the discs instead of being deep between the discs.
3. Check the needle plate and the loopers for rough areas. Sometimes the needles strike these parts and cause "burrs" which can grab the thread and not let go of it properly and it breaks or shreds the thread.
4. Some needle plates have pin like guides pressed into them. The sewing needles decend between these plate guides, however sometimes when a serger jams they can be broken. Verify that they are still there. They are very important for proper stitch formation, If they're gone, a new needle plate is needed.

I hope this helps

Hi there, my husqvarna 936 is jamming slightly when i turn the hand wheel and when i use the pedal it works but their is a load catching noise can you help me plz


Hello, The first thing to do with a serger is to change the needles and take the thread off the machine and rethread it. The 936 can sometimes "fight" you a little when it comes to getting the needles up in all the way. It's critical that they are inserted all the way up in the needle clamp. Check to also make sure the N/R lever is in the N position. Check the needle plate, are the "needle like" pins still attached to the plate? If your serger jammed, sometimes the thread breaks the pin supports out of the plate. They are very important when it comes to stitch formation.

How do i put the bobbin case back in correctly?


The zigzag setting should not have caused it to jam up unless the tensions were off and the thread was bunching up on the bottomside of the needle plate. If you ever jam or break a needle be sure to replace it with a fresh new needle. A slightly bent needle will cause all kinds of problems.
When putting the bobbin back in make sure you keep a good amount of thread hanging out and manually turn the hand wheel around until the needle make a full rotation. The hook should catch the needle thread and allow you to pull the bobbin thread out through the needle plate.
If you jammed it really good it is possible that the needle and hook timing is out of sync in which case you may need to have it re-timed.

Bobbin thread not being picked up


This unfortunately sounds dismally like a timing problem. When a sewing machine makes a sudden mechanical stop as when a needle is bent slightly and hits the needle plate, sometimes the other machine bits revolve along further causing the needle to be introduced into the hook either to early or to late to catch the thread.

To test this, remove the thread, the needle plate and and the bobbin case. Replace the needle with a brand new one. Yes, again. Revolve the machine by hand via the balance wheel and watch closely as the needle goes into the hook region allow it to it move down and then just start to move up. If the tip of the hook is not pretty close to right behind the needle than it is more than likely a timing problem.

If the tip of the hook is behind the needle in the scarf (the slight hollow on the back of the needle) than it is not timing. Thread the machine normally like it is and watch what happens as you manually turn the machine via the balance wheel. The thread should catch and be pulled around the hook and let go.

Try this and then either you figured it out the problem or contact me again. Either way please vote. Thanks
