My Toyota 444 sewing machine. When sewing,stitches ok on right side of material but underneath,stitches are entangled. sometimes it stops sewing and I have to pull thread out.


ALWAYS RAISE the presser foot when threading the top thread. (You will need to remove the top thread from the machine and rethread from the beginning.)

For tension, start out with it set about the mid-point on the tension dial. Then tweak it from there. If top thread is showing on the bottom of the fabric, tighten the top tension. If bobbin thread is showing on the top of the fabric, loosen the top tension. It's ideal when both threads meet in the middle of the fabric.

Two things I can suggest.

First, look at this search result and see if any of the manuals refer to the machine you have:
https://www.google.com/search?num=100&safe=off&q=sewing+machine+overlock+manual+filetype%3Apdf

Second, check with your local sewing circle or quilting group. You can usually find them at the local library or via Google.

Stitch too tight on top, too loose on bottom


This is a problem with thread tension. The needle thread is too tight and the bobbin thread is too loose. I don't have one of these machines, but there should be either screws or knobs to adjust. Look at your manual. Here's a page I found on bobbin tension.

The lower thread does not bring up , so that the uper thread does not come in contact with the lower thread .I hear unusaul noise while sewing.All these happend when I tried to sew a jeans .i used a thread...


As a general rule, domestic machines don't like buttonhole twist, that heavy yellow thread you see on the RTW jeans. Sometimes you can put it through the bobbin but use a regular weight thread on top but this means sewing upside down as you'll want the yellow on top. And lots of machines dont like different weight thread top and bottom so it just makes for awful stitching anyway.

Best solution to top stitch jeans is use a regular weight thread, large size jeans needle but thread up two spools of thread on the top with both threads going through the same needle eye. It still may not solve the problem though.

To your machine, firstly change the needle as it may be bent. Then unthread the machine and manually turn the flywheel through a stitch cycle and listen carefully, if you still hear a noise as the needle touches the rotary hook, you've knocked the timing out. Service man visit time.

Probably if you check the manual, it will say 50 weight thread, and you'll need to stick with that in the future.

Those big industrial sewing machines that they top sew jeans on are very different to a domestic SM, many make a chain stitch or fell the jeans seams and are very heavy duty.

Upper thread brakes often. The baste stitch is way too loose on underside of stitched fabric. I have taken it for a ture-up ($65) at a sewing machine repair shop... and it still has these issues. This is...


It could be your thread is old, dry and brittle, always store out of sunlight and in airtight container to avoid this. You could try putting the thread into the fridge overnight to add a bit of moisture back into it. Or buy some new thread and try again. Also, always use same thread on top as in the bobbin, don't be tempted to just use an old bobbin of thread you have already as different colours and thread top and bottom will affect stitching quality.

If you are getting loops on the underside it also sounds like top tension is not right. Check dial is on 5, and always raise the pressure foot when you are threading up so the tension is open for the thread to go into.

Then lower the pressure foot and pull on the thread below the tension - it should feel firm when you pull it. Also revisit your threading up, it is possible that the thread is catching somewhere between the spool and needle causing it to break so check with your manual carefully to see if you have missed a threading eye.

Failing all of this, go back to the shop and ask them to watch you thread up and see if they can spot the issue.

Hi, my lower tension will not adjust no matter what I try. The top stitching is fine but the lower stitches are very loose. My machine is quite old but in good condition. It is a model 2201 EC1 Series. I...


Be sure to ALWAYS RAISE the presser foot when threading the top thread. This allows the thread to seat completely in the tension disk. The higher the number on the tension disk, the tighter the top tension. If the bobbin thread is laying on the surface of the fabric, try increasing the top tension.

Thread tension is basically a tug-of-war between the two threads. They should exert the same amount of pull against each other. Perfect tension is when both threads meet in the middle of the fabric.

Of course, since your machine is older and parts do wear, your machine may need an adjustment or even replacement of some parts, like the bobbin case. The tension spring on a bobbin case will wear over time and the top tension may lose some of its tension.

TIP: Be sure to treat your machine to some well-earned TLC--cleaning and oiling. Oil dries out over time and will begin to stick parts so they no longer move freely. Below is the method I've used to free seized machines. You'll be amazed at how nicely it runs and your machine will run for many more years!!!

Wheel on right side that controls the needle up and down is very tight...

Oh yeah, here's a manual:

Bobbin tension?


Try threading the machine with the presser foot up to see if this will solve the problem.

When a sewing machine is threaded with the presser foot down, the thread cannot properly enter the tension. No tension control of the top thread and it cannot form a satisfactory stitch.

You might be able to find a manual for your machine at sewusa.com

Stitches are not connecting top to bottom


Try re threading the machine with the presser foot up.

When you thread with the presser foot down, the thread/string cannot properly enter the tension control.

No control = looping stitching that pulls out.

If you do not have a manual, you may be able to download a free one at Brother's website.

Top thread doesn't pick up the bobbin thread (Toyota sewing m.)


Hi! This may sound silly, but if you changed your needle and put it in backwards (which is easy to do), the top thread won't pick up the bottom thread. Take your needle out and check the flat side of the needle shank--which way is it facing? With a lot of the newer machines, the flat side goes to the back, but check your manual to make sure.

Let me know if this helps, ok?

Happy Sewing!

My four-year-old XL3500 seems to have a tension problem. It was sewing fine until after I refilled the bobbin, changed thread twice, and did some zigzag stitching. Now the top stitch is not correct; it...


according to the diagram in the manual, the upper thread tension is set by the wheel/knob on top and just to the right of the thread take up lever and thread guide. If you don't have a manual, go to www.brother-usa.com they have a downloadable manual for your machine.
