Most machines have an average tension of 4. Start there and adjust as needed.

How can I set the right tension on an overlocker globe lock m-34?

The right tension on an overlocker will vary depending on the result that you want. The standard tension for just a plain 4-thread overlock stitch would generally have all the thread tensions set at the halfway mark between the high and lower number. From that point, you may need to tighten or loosen each thread tension to get all the threads to stitch evenly.

Probably the best advice would be consult your owner's manual. It should have instructions on adjusting the tensions and what to look for.

Another suggestion would be to search YouTube for a video that shows how to adjust overlocker tension.

so when the mech opens hood, he looks for the tension method first;. (a real tensioner device or is it just the alternator slides.
this is first.
they used 3 alternators that year.

power steering pump adjuster
a/C compressor adjuster.
we look and see that in about, 1min flat.
so do that first.
there are some engines with stand alone tensioner devices
some are automatic others are manual set.
the FSM covers all this
if serious about DIY, why not buy one
or log into for 15 bucks and read.

If, you look at your manual, you will see on page 29 there is a tension dial, right on top of your machine. It may help to download a copy of your manual at and enlarge the diagrams to see all of the parts and suggestions of what needles, etc to use for each project.

Thead tension or space is too loose

If you have your manual for this machine, look on pages 13-16, and check the troubleshooting guide on pg 20. Both explain quite clearly in pictures and words, with suggestions on what starting tensions to use for your project, and how to fine-tune your machine for the best outcome for your fabric..

If you don't have a manual, try this: set all four tensions to four, grab some fabric scraps similar in weight to what you're trying to sew, and test. Serge about 3 inches, check the front and back. If there are not two nice straight rows of what looks like straight stitching clearly placed away from the cut edge, then raise the dial on tensions 1 and two slightly and test until you find the correct setting. BE SURE TO WRITE IT DOWN as a calibrated starting tension for your machine. If the serger track is loose on top and there are not clearly defined, uniform loops on the cut edge, where the upper looper (tension 3) and the lower looper (tension four) threads meet AT the cut edge, then you'll need to loosen tension 3 or tighten tension four, or both.

I've scanned my manual and I'm trying to upload it tonight - it clearly explains, with illustrations, just how to fix the issue. I strongly recommend any time you start a new project, save some scraps of fabric to set your tensions with. I always do this, and I get great results. Let me know if you need more info.

Zig zag stitch

If your stitches do not look good on the top side you have a problem with the bottom thread. make sure you have the correct bottom tension: Is the thread under the bobbin tension plate and when you hold the bobbin and case lightly in your hand the tension should be set in a way that there is little resistance , yet still some, when you pull the thread. After you set your bobbin tension, you may have to adjust your top tension to balance. Also make sure the thread comes off of your bobbin the way your manual tells you, clock or counter clock wise.
Make sure your bobbin (plastic) is not sooooo old, buy a new one.

Tension setting XL 3500 Brother

Hi, and welcome to FixYa. Normally, the default top tension setting on most machines is between 4 and 6. Brother manuals usually contain detailed information about tension and how to determine if your tension is set correctly, so check that section of your manual when you have time....if you don't have your manual...

you can find a copy to download for free on Brother's website (I added a link to the web page below). The same web page has other information about your machine that you might find helpful now or in the future. Even if you have the manual, it is worth a visit.

If you and other readers have a minute to rate my answer, it helps me better understand what readers are looking for when they come to the FixYa site for help.

Best of luck, and enjoy your machine. Don't hesitate to comment if the link doesn't' work, or if you have more questions. Cheers!

Hello I have misplace the manual for my Janome 234D. I bought it a few moths ago and i set all the tension right and had it going good. But my young grand daughter got to it while i was out and turned all...

Tensions all should be set at "3" for general sewing if there is no other damage or lint trapped in the tension discs.
Try "flossing" each tensioner with a piece of cloth to remove lint.
If you are still uncertain, try 4 different colours and with all set at 3 to begin, adjust to suit what you see to be loose or tight (small adjustments each time)
If the little one has removed the knobs (they just pull off towards you) and turned the white adjustment wheel beneath, you need to set until happy as above, then put the outer knob back with number 3 in the 12 o'clock position.
Best of...
