Looking at a pic of this model, there are two dials on it. One near the top, one much closer to the needle. I believe the tension dial is the one that's close to the needle.

I don't quite understand what the problem is with the stitches from your description, but first try the tension dial. Reset it to zero and then try each setting, one by one, to see what happens.

If stitches are still wrong, a few things always to try when there are stitch problems. Clean well around the bobbin case, remove all lint. Do this often anyway, it's not good to let lint build up.
Try a new needle and a new spool of thread. Rethread the machine, a few times if need be. Try a new bobbin too, or wind a new bobbin to try from a new spool.

Try to get a manual for this machine. If Brother no longer has manuals, there are many sites that sell manuals for many machines. A manual can be your best friend when there are problems.

SOURCE: stitching looping

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.....the question you pose could have 2 meanings....this reply is for looping thread.

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....

cc3f045.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.

1eade63.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. ie a different colour top and bottom just for the test.

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 consistant diameter with good thread, and less compensating to be done by your tension plates and less thread breaks !

If you need any more help with this, just post back here, or, drop a line through the "Contact Us" page at www.bargainbox.com.au

SOURCE: how to adjust tension on bottom stitch?

There are tow places where the thread tension is adjusted.

One is bobbin. This is not routinely adjusted. Just once and it is good for long time. This is done by turning the only screw on bobbin by about 1/4 turn or so at a time. Try several settings until you find he best.

the other place is the conventionally on body of the machine.

Tension of bottom stitch or top stitch are very confusing words. meaning difft things to difft pple.
All i can say is this. If u see bottom stitch run straight through loops of top thread. then either top tension is too loose or bottom too tight. and vise versa.

With top tension set to middle position adjust the bobbin to get correct stitch. Then later on all u need is to adjust only the top setting according to stitch and cloth

SOURCE: Shirring fabric?

When putting your shirring elastic on the bobbin, don't thread the elastic through the bobbin holder,adjust the stitch length longer,and loosen the tension, other wise if you want to put it through the bobbin holder you have to loosen the tension screw on the bobbin holder, and then you have to adjust it back for ordinary sewing,

SOURCE: how do i set the tension on my brother xl-3010

I don't have this machine, but the tension on the bobbin is usually set by the tiny screw on the bobbin case. insert the bobbin into the case so that the thread unrolls counter clockwise. Make sure that there is no lint in the bobbin area.

How to adjust the bobbin tension.

According to the manual, you should not need to adjust the bobbin tension (and I located other sites which stated the bobbin tension cannot be adjusted on this machine). Apparently, all the tension adjustment is accomplished through the upper thread::
"EN Thread Tension Upper thread tension Basic thread tension setting: "4". (1) To increase the tension, turn the dial to the next number up. To reduce the tension, turn the dial to the next number down. A. Normal thread tension for straight stitch sewing. B. Thread tension too loose for straight stitch sewing. Turn dial to higher number. C. Thread tension too tight for straight stitch sewing. Turn dial to lower number. D. Normal thread tension for zig zag and decorative sewing. Correct thread tension is when a small amount of the upper thread appears on the bottom side of fabric. Lower thread tension The bobbin tension has been set correctly at the factory, so you do not need to adjust it. Please note: - Proper tension setting is important for strong seams. - There is no single tension setting appropriate for all stitch functions, thread or fabric. - A balanced tension (identical stitches both top and bottom) is usually only desirable for straight stitch construction sewing. - 90% of all sewing will be between "3" and "5". - For zig zag and decorative sewing stitch functions, thread tension should generally be less than for straight stitch sewing. - For all decorative sewing you will always obtain a nicer stitch and less fabric puckering when the upper thread appears on the bottom side of your fabric. 1 A B C 22 D"

Doing further research, I found this statement on a machine review site:
"After reading reviews online from where I've bought my drop-in bobbin machines, I think many of the negative reviews are due to the bobbin thread coming up without laying across the bobbin. It can cause the stitches to look very sloppy and no amount of tension adjusting can fix the stitches."

There are several machine review sites wherein 4423 owners stated their disappointment in the 4423's performance. Some said the machine failed almost immediately and others said the machines developed problems when sewing heavy fabric.

Bottom thread is still loose even if i try to balance the tension, how do i balance the thread tension?

You bobbin tension CAN be adjusted. First, thread your machine with different colors in the top and bobbin, set your top tension at its default, and run a line of straight, and then a line of zigzag stitches, and compare the results at the top and bottom. You will be adjusting your bobbin to your top tension. If the top tension looks like a straight line instead of stitching and the zigzag looks like "chicken tracks" instead of a zigzag, but the bottom looks like a zigzag, your bobbin tension is too loose.

Remove the bobbin case, and locate the straight-slot screw. There are generally two; one is a Phillips and one is straight--you want the straight one. Leave the other alone.

The rule is "lefty-loosy, righty-tighty." If your stitching displays the above symptoms, it needs to be tightened, so turn 1/4 turn to the right--no more--then test again. You will need patience, but don't turn more than that. It is easy to do, but if you don't do it systematically, you can make things worse, and very slight adjustments can alter the stitching significantly.

What is the setting for gathering

Loosen the top tension until you see little loops on the bottom. Lengthen stitch length. Test first on scrap to get it down... sew a line then gather by pushing and pulling the bobbin thread. (don't pull it out!!)

Another way to do it without a special foot is to zig zag over a cord. :)

Once you have the gathers distributed... re-tighten the top tension and test on scrap again... then stitch your gathers in place.

I have a Singer

Which stitch are you using?

To check thread tension for straight stitches, use different colors of thread in your top thread and bobbin. If the top thread shows on the bottom of the fabric, turn the dial counter-clockwise (towards a lower number). If the bottom thread shows on the top, turn the dial clockwise. Do not adjust the tension too much (for example, go from 2 to 2.5 if increasing the tension) at a time; test another set of stitches. Alternatively, you can adjust the bobbin tension in the reverse directions. However, it's very easy to damage the set screw in the bobbin case so do this as a last resort. Since this is a vertical bobbin case, put the bobbin in and hold onto the thread. If the thread moves when you dangle the bobbin case, tighten the screw. Loosen the screw if the thread doesn't pull out of the bobbin when you hold the unit.

For zig-zag decorative stitches lower the tension until the puckering stops. Usually the top thread will show on the bottom of the fabric.

If the tension is not changing when you turn the dial, make sure that the presser foot is down. The sewing machine may need repair. The tension mechanism depends on a spring and that can break. See the Singer site for a parts breakdown and contact your Singer dealer for the parts.

If the top and bottom fabric are not moving at the same rate, you can get a different type of puckering. You may want to get an even feed foot if there are several layers of fabric.

The manual for the 3116 is available from Singer: http://www.singerco.com/uploads/download/438_3116.pdf .

I have a singer 7258 that I can not get the tension to loosen up on. The top stitch is straight across and adjusting dial doesn't help.

Hello

Adjust the tension

Load your sewing machine with one color on top, threaded through the needle. Load the second color thread into the bobbin and thread.


Fold the scrap fabric in half, and sew a straight stitch at least 2 inches long. Look closely at the seam. If you see loops of the bottom color thread on top of the fabric, proceed to Step 3. If you see loops of the top color thread on the bottom of the fabric, proceed to step 4.


Loosen the top tension. Since the top tension is so tight, it is pulling the bottom thread up through the fabric. Loosen the top tension by turning the numbered knob on the front of the sewing machine counterclockwise by one number.


Tighten the top tension. Since the top tension is too loose, the bottom thread is pulling the top thread down through the fabric. Tighten the top tension by turning the numbered knob on the front of the sewing machine clockwise by one number.


Sew a straight stitch 3 inches in length. Check the stitching. It is perfect if the threads meet in the middle, and you can only see the top thread on top and the bottom thread on bottom. If it still needs adjusting, go back to step 2 to repeat the needed steps.


Using two different colored threads makes it easier for you to see which thread is being pulled.

Always use proper precautions when working with electrical machines.

I'm having trouble gathering fabric...no matter how I adjust the stitch length it seems to be too tight and I break the threads when I try to gather. Help!

So you are sewing two rows of straight stitch at 10mm and 20mm from fabric edge with a stitch length of 4? Are you using good quality thread? I like Molynecke, Guttermann or Sylko Supreme.

Try loosening the top and bottom tension too, and use a gathering foot if you have one.

A quick solution is to zig-zag over a length of pearl cotton or similar heavy weight string/thread, this works well for large volumes of gathers such as around a bed valance frill.

For large volume gathering like cushions and bed frills, I use a pleater/ruffler attachment, however, this has only 3 settings so isn't a variable gathering effect.

Gobbs of thread gather on backside of material, while front stitch is good...how do I correct this

Hi! Here are two things to check that generally cause problems like this:

1. Check that you're threading the machine correctly, especially the take-up lever.

2. It may be that you need to tighten the top tension. When the top tension is too loose, it'll cause big gobs of thread, like you say, on the back of the material. All this thread is actually top thread (not bobbin thread). (I recommend using different colored threads in your top thread and in your bobbin when you suspect tension problems.)

A couple of things to remember when you are adjusting the tension:
  • Always adjust the tension with the pressure foot DOWN.
  • Thread the machine with the pressure foot UP (so the thread can slip easily into the tension disks).
  • The higher the number on the dial, the tighter the tension.
  • Adjust in small increments. Stitch a few inches, check, adjust, stitch, check adjust--and repeat as needed.
I'm in the process of posting some photos about tension adjustments on www.robbiesews.blogspot.com. Check there later tonight and I should have them up.

Let me know if this helps, ok?

Can't balance top/bottom thread tension-model 158.Bottom thread is a straight line. Have increased top tension to the stop. No effect.Have reduced bobbin tension until bobbin and case fall freely when held...

I disassembled the top thread tension controller consisting of 12-13 pieces, including 2 springs. Since they all fell out on the table I spent about 2 hours learning the proper stacking order on the central shaft.
With a combination of reasoning based on each unique piece shape and trial and error I put it back together, adjusted top and bottom tensions according to the instruction booklet for the machine, tested some stitching, made final adjustments and all worked well.
I don't know what was changed in the process but it worked.

If it was sewing correctly BEFORE the needle break...why did the needle break in the first place?...and what fixes did you make?
If it sewed properly...what changed?

Cut your upper thread close to the spool...make sure the presser foot is raised and pull the cut off thread section through/out of the machine from the needle area (sewing direction...do not pull the thread backwards!)

Clean out the bobbin area...remove any traces of lint or pieces of thread...look for any broken off needle pieces... brush the bobbin area out....then add a drop of sewing machine oil (but only if your manual says to oil that area).

Remove the needle plate to expose the feed dogs...brush/clean out that area too and add a drop of sewing machine oil...then secure the needle plate back on.
Replace the needle...do it again...yup...some needles arrive bad from the factory. Make sure the needle is inserted and positioned properly. Then thread the machine WITH the presser foot in raised position. (The thread needs to get seated into the upper tensions.)
..with the.presser foot down...thread the new needle.
Oh...and use the correct needle for the thread. (a universal 80/12 is standard).
Thread can cause issues too. Try a different bobbin, or maybe a different spool of thread to see if that makes a difference.
