To change tension on a Brother PE800, turn the numbered dial on the top of the machine to a higher number for tighter stitches or a lower number for looser ones. Lift the presser foot first so the thread sits between the tension discs, and leave the preset bobbin case alone.

The dial is the only adjustment most embroiderers need. Once you know which way to turn it and what a balanced stitch looks like, tension stops being a guessing game and becomes a quick check before each design.

What does the tension dial on the PE800 actually control?

The dial controls the grip on the upper thread as it travels from the spool to the needle. Turning it changes how tightly that thread is held between two metal discs inside the machine.

A higher number squeezes the discs harder and pulls the top thread tighter. A lower number lets the thread feed more freely.

The bobbin case is set at the factory, so the top dial is the part you change.

Set the dial with the presser foot up. With the foot down, the discs close and the thread can slip outside them, which makes the next stitch behave as if your adjustment never happened.

How do you set the tension on a Brother PE800 step by step?

Raise the presser foot, thread the machine normally, and turn the dial to your chosen number before you lower the foot. Then stitch a test design and adjust from there.

1. Turn the machine off and raise the presser foot so the tension discs release.
2. Make sure the thread is fully seated between the discs on its way to the needle.
3. Turn the dial to 4 as a starting point and lower the presser foot.
4. Hoop a scrap of your project fabric with the same stabilizer and stitch a small design.
5. Look at the front and the back, then raise the foot and turn the dial one step.
6. Repeat until the top and bobbin threads meet evenly in the fabric.

Change only one step at a time. Big jumps make it hard to tell which adjustment helped, and small moves keep the discs from being squeezed harder than needed.

How do you know which direction to turn the dial?

Look at where the stray thread shows. If the top thread shows through on the back of the fabric, the upper tension is too loose.

If the bobbin thread shows on the front, the upper tension is too tight.

Most embroidery designs should show mostly the upper thread on top and mostly the bobbin thread underneath. When both meet in the middle of the fabric, the stitch is balanced and the design looks crisp.

Keep a note of the numbers that worked for your go-to threads. Dark rayon on a lightweight cotton often wants a slightly different setting than polyester on a towel, and a written record saves you from starting over each time.

When should you loosen the tension?

Loosen the tension when stitches pucker the fabric, the design pulls in at the edges, or the top thread breaks. Turn the dial to a lower number in one-step moves until the fabric lies flat.

Tension that's too tight is a common cause of thread breaks. The upper thread snaps because the discs hold it so hard that the needle can't pull it through cleanly.

Backing the dial down a notch or two often fixes it.

Puckering has other causes too. A dense design on thin fabric needs enough stabilizer, and a hoop that's drum-tight can also pull the edges.

Fix tension first, then look at stabilizer and hooping before blaming the machine.

When should you tighten the tension?

Tighten the tension when loops of top thread sit on the back of the fabric, or when the underside looks loose and fuzzy. Turn the dial up one number at a time and stitch another test.

Loops on the back usually mean the upper thread isn't being held firmly enough to pull the bobbin thread up into the fabric. A small increase usually brings the two threads back together.

Check the threading path first. If the thread skipped a guide or jumped out of the discs, a tighter setting won't help and may make things worse.

Rethread from the spool, then adjust the dial.

When do needles and bobbins matter more than the dial?

Sometimes the fix isn't tension at all. A worn needle or a bobbin wound unevenly can mimic a tension problem, and changing the dial only hides the real cause.

An embroidery needle has a wider groove and a larger eye than a standard sewing needle. The Schmetz Embroidery Needles 75/11 set is sized for rayon and polyester on home machines, and the wider eye helps the thread pass without shredding.

A fresh needle every few projects keeps the stitch clean. A bent or dull point catches the fabric and drags the thread, which reads as uneven tension when the dial is set correctly.

Which bobbin thread keeps tension steady?

Use a bobbin wound evenly with fine bobbin thread, because a lumpy wind snags and pulls the stitch unevenly. That is why prewound bobbins suit beginners so well.

The New brothread 25-pack of Size A SA156 prewound bobbins holds 60-weight white polyester. A consistent 70D/2 filament gives steady draw-off from the first stitch to the last.

The plastic sides keep the thread clean and let you see how much is left. White suits most projects and is easy to match when a design calls for a light bobbin.

What should you do about bobbin tension on the PE800?

Leave the bobbin case alone. The PE800's bobbin case is preset, and the numbered dial on top is the control the machine expects you to use.

Tightening or loosening a bobbin screw by hand is easy to get wrong. It also takes a small screwdriver and a steady hand, and once it's off, every future design feels inconsistent until it's reset.

If the bobbin thread pulls up badly on top even after you raise the upper tension, check the bobbin first. A bobbin that's loaded the wrong way or a case with lint in it causes more problems than a correct case ever will.

Why does the thread keep breaking even after you adjust tension?

Check the needle, the threading path, and the thread itself before turning the dial further. Tension is only one of several reasons an embroidery thread snaps.

A needle that's too small for the thread, a burr on the needle plate, or thread that's catching on the spool all break the top thread. Lint packed in the bobbin area does the same.

Try a fresh needle and rethread from the start. If the break happens in the same spot every time, look at the design file and the stitch density there, not just the tension dial.

Which machine settings and accessories help you keep tension steady?

A clean machine, the right needle, and even bobbin thread do more for stitch quality than frequent dial changes. Set the dial once for your thread and fabric, then leave it.

Wipe lint from the bobbin area and under the needle plate after each big project. Lint in the discs changes how the thread feeds, so a clean path makes your saved settings repeatable.

Which Brother machine suits a beginner learning tension?

The Brother SE700 is a sewing and embroidery combo for someone starting out. It has a 4 x 4 inch embroidery field, a 3.7 inch color touchscreen, and 135 built-in designs, so there's plenty to practice on.

The screen lets you preview a design before stitching, which helps when you're testing a new tension setting on scrap fabric. It's a sensible first machine before you commit to a larger hoop.

If you're weighing this machine against its sibling, our comparison of Brother PE800 vs PE900 covers how the models differ. Our Brother Skitch vs SE700 piece helps if you also want to sew garments and home decor.

What mistakes should you avoid when adjusting tension?

Don't turn the dial while the presser foot is down, and don't move it several numbers at once. Both make the stitch unpredictable and hard to correct.

Never force the dial past its marked range. If it feels stuck, stop and check for thread or lint caught in the discs rather than twisting harder.

Don't chase a perfect stitch on fabric you haven't stabilized. Tension can only do so much when the fabric stretches under a dense design.

Add stabilizer and rehoop before you touch the dial again.

How do you keep tension right for your next design?

Recheck the dial whenever you change thread weight or fabric, because the setting that worked on cotton won't always suit a towel or a knit. Raise the presser foot, confirm the thread sits in the discs, and stitch a small test first.

Write down the number you used for each thread and fabric pair. A quick note on your hoop or in a notebook saves the trial and error next time.

Our guide to magnetic hoop vs regular hoop explains how the hoop you choose affects fabric stretch and stitch quality. When you load a design, knowing your embroidery machine file formats also helps you spot a stitch count that's too dense for your setup.

Changing tension on the Brother PE800 is a small, repeatable habit. Turn the dial one step at a time, keep the bobbin case alone, and let a test stitch tell you when it's right.

Frequently asked questions

Which way do I turn the tension dial to loosen the top thread?

Turn the dial to a lower number to loosen the upper thread. A lower setting feeds thread more freely, which helps when stitches pull the fabric or the thread keeps breaking.

Does the PE800 have a bobbin tension screw?

The PE800's bobbin case is set at the factory and doesn't have a user tension screw to adjust. The numbered dial on the top of the machine is the tension control you turn.

What number should I set the tension to for embroidery?

Start near 4 and adjust in small steps from there. The right number depends on your thread and fabric, so raise it a notch if the top thread shows on the back and lower it if the bobbin thread shows on top.

Why does my top thread keep breaking?

Too much upper tension is one common cause. Lower the dial a step or two and check that the needle is an embroidery needle with a wide eye and that the thread is threaded correctly.

Can wrong tension cause puckering?

Yes. Tension that's too tight can pull the fabric into ripples around a design.

Back the dial down and add a layer of stabilizer before stitching dense designs.
