Putting this back together is a thirty second job if you have done it a hundred times. If you have never done it but have mechanical aptitude, it may be a challenge.

Whatever you do, don't bend the check spring out of shape!

Below is a link to the Singer site with the schematic for reassembly. When placing the check spring back in place, place it in about the 6 o'clock position with no tension so that it has a fair amount of check before pulling it up in place..

When setting the tension, at a setting of "1" the tension disks should just be slightly compressing the beehive spring. "0" is almost no tension at all. Normal sewing is 5.

Get all of the parts together and push in the cup with the numbers while screwing on the knurled nut taking care to get the pin in one of the holes.

SOURCE: Problem with tension on singer tiny tailor mending machine

Please TRY the solution BEFORE giving your considered rating.
Specific detail on bobbin case adjustment (with picture) near halfway down reply, the remainder will help you achieve a balance of top and bottom tensions.

Ensure that all is clean and free of lint and jams, this is the most likely cause....now for tension troubleshooting .......

This solution is for tension problems...if you cannot form any sort of stitch, the issue is quite different, so please let me know if you need a different problem solved.....

It is quite long, but just work through each section in order.

The "knotting up" can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.

QUICK SUMMARY FIRST:
Ensure sharp new needle,
Thread guides and Bobbin are Clean & Clear of lint
Set Top Tesion to 4 ....then....
Balance Bobbin to suit.

TOP THREAD TENSION:
If the looping threads are on the underside as you sew, it is the top tension. Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your projects).

IS YOUR NEEDLE SHARP ?
If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one !

TOP TENSION & GUIDES:
Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and not to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp.

It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically.

If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread.

Now, with a 2" (50mm) wide strip piece of fabric 8 - 10" (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with a see saw / to and fro action.

In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to disengage tension plates).... do not gouge or score the plates, they need a polished surface to work correctly.

BOBBIN TENSION:
Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a "false" tension.

I would not recommend fiddling with bobbin tension without good reason, it may end up with missing small screws and spring pieces, however, you can take the needle plate off to clean
the hook race area (where bobbin case sits)

...this is just good housekeeping, my wife does this every time she replaces the bobbin....

just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint. If there is a significant amount of lint, use a vacuum and small brush to get the worst.

Then wipe all this area with a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit, especially if there appears to be fine dirty deposits....oil and lint combine to conspire against you.

If it seems likely that you ......really ....do .....actually .....need .....to adjust the bobbin case, first check there is no lint trapped in the metal spring where the thread is tensioned.

TOP LOADER:
Drop-in Bobbin case will look similar to this image with the tension screw in the middle of the metalwork....

4c76dc1.jpg ...the other screw at one end is holding it all together, so beware....it is not a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out !

FRONT LOADER:
....this is a bobbin case from a front loading machine and works in a very similar fashion to the top loader with drop in bobbin, again, if you dismantle it, take care so you can put it all
back properly.
165ca5c.jpg FINISHING UP
GETTING THE BALANCE RIGHT:
When you are certain there's no trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.

Try using good quality thread of contrasting colours so you can more easily spot the changes.

Set your zigzag to one width less than maximum (eg. 5 of 6 ...or... 4 of 5 etc) and sew a sample for a few inches and check the result.... adjust the bobbin tension screw very little at
a time, perhaps 1/16 of a turn.

You may find you are playing with this balance for some little while and if you are putting the needleplate on and off each time begin to think it cannot be correct to do this.....BUT....it is,
and eventually, you do get a "feel" for the correct tension and then it happens quite quickly.....as a user you won't be doing it very often unless there is lint built up (or are there small hands at work around the house !?!?!)

OTHER ISSUES:
If you live near the ocean as we do, salt air can play havoc with metalwork inside and out, so to help minimise this, keep a few small packets of dessicant (silica gel) in your machine
case....no case ? then make some sort of cover !

Same applies in any damp or humid environment, keep your machine dry and dust free.

Budget for a proper full service every couple of years (more often if heavily used) and if you don't use your machine for a few years, be aware that old oil will dry out and combining with
dust and form a "clag" like glue (another reason for some sort of cover, even a teatowel !)

FINALLY, A WORD ON THREAD:
If it is worth spending the time, energy and money on making something that you would like to give lasting enjoyment......use quality thread, .......it may seem to cost a little more at the
time, but the results, ease of use and added longevity will be worth the extra, and as a bonus, your tension troubles may be fewer and further between, because there is a more consistent diameter with good thread, and less compensating to be done by your tension plates and less thread breaks

Singer 756u stitches not catching


So this is a serger? Might have been nice to know that. Make sure you have threaded your serger in the correct order. upper looper, lower looper, needles from right to left.

Make sure you do this with the presser foot lever in the UP position. Make sure all the threads are pulled fully into any tension guides.

Serger randomly stopped working, could it be power cord? plug?


Make sure there isn't lint caught on the loopers if it is not a loose connection from the machine/wall. On some machines, if the bulb has blown out, the machine will not operate until replaced. It sounds to me like fabric or thread is caught and, therefore, your machine has temporarily stopped until you unplug it and remove the debris.
Hope this helps!

The top left thread is not engaging with the other 3 threads. Help! I have rethreaded the machine twice.


Have you changed the needles in your serger before this happened?

If so, check again that the left needle is fully up into its housing and that the needle is in the right way with the scarf (cut out) at the back. Have you got a ball point needle in one side and not the other perhaps. If you are seaming knits, then put in 2 ball point needles, if for wovens, then two sharp needles.

Now check tension on left needle, is the number on the dial the same as the right needle. Pull on the left thread just after the tension disc then the same on the right thread, does the tension feel the same on both?

Is the thread catching somwhere on the aerial, caught on the cone holder, or at the back somewhere or as it comes through the tension discs? Take thread out of the discs, turn dial to zero and give between the discs a good clean with the selvage edge of a clean piece of cotton waste fabric, saw it back and forwards to clean out the discs. Now thread the machine again again. I'm assuming this is a 4 thread serger, so thread order would be top looper, bottom looper, then right needle, left needle, turn tension to zero on all threads, pull all four threads out under the foot, loower the pressure foot, turn tension back to five on all (or whatever your normal setting is) then chain off a little and test sew.

I hope this helps resolve your issue.

Lower looper problems


Some sergers require they be threaded in a particular order. If not, they do not "knit" the threads.

Raise the thread antenna to it's highest position.

Open the tensions (set at zero). If the tension settings are automatic, raise the presser foot to open the tension settings.

Turn the handwheel so the loopers are at their highest position. There may be a mark on the side of the serger to match up with a mark on the hand wheel for this.

Open the front of the serger and the threading guide should be printed on the inside of the serger door, or on the serger.

Start at the right and note which looper is threaded first and then the needles.

You can find more information and manuals at the Singer Co website.

Problems With the Tension serger kenmore


Open the tensions (set at zero) and have the presser foot up when threading.

Make sure the antenna if fully extended.

Turn the handwheel so the upper looper is at it's highest position.

Thread, beginning at the right thread cone unless the manual indicates differently.

After threading, set the tensions back to the recommended setting.

If this does not help, please provide more details.

The threads are not tight on my serger


Here is an easy way to get your thread adjusted. Rethread the machine using four different colors. Then sew and for example the "yellow" thread is loose on the fabric, you know to adjust the tension with the yellow thread. Also a good starting place on your dials is 4-3-2-1 from left to right. Start with the tension set there and then adjust as needed.
