Question about Janome Sewing Machines

2 Answers

I can't get the tension right on my Janome DKS30 sewing machine. I can operate a machine but I am quite a novice. My machine is 9 months old and I have used it less than 20 times. Can you please help?

The stitches underneath the fabric look ok but the top stitches look like the thread has not gone through the fabric to join the bottom thread so the bottom thread is just a tiny loop on the top of the fabric with the top thread running through. Sorry if it's a jumble but I don't know how to explain it better. Thank you, June.

Generally, if the thread issue appears on the top of the fabric, it is the result of a bobbin thread problem. In your case, it is probably something to do with the bobbin tension or threading. Remove the bobbin from the bobbin case. Make sure the thread is would smoothly on the bobbin. Check that when the bobbin is installed in the bobbin case that is turning the correct direction (consult your owner's manual). The bobbin turning the wrong direction will affect the tension. Also, verify that you are threading the thread through the bobbin case tension spring properly.

Further, if the upper thread is pulling the bobbin thread to the top of the fabric, the upper tension is too tight. The factory standard is usually the midway point between high & low number.

Since your machine is relatively new, it is probably still covered under warranty. You can have a Janome dealer check it for you. New machines sometimes are defective.

The following sites may be helpful. Keep in mind that adjusting the bobbin tension screw is a last-ditch effort, as tiny adjustments can make a huge change. It is easy to get it further out of adjustment. Be sure to mark the original screw slot position BEFORE making any changes so you can reverse them if things get worse.

My janome mylock 644d threads are continually breaking, have threaded the machine correctly, will sew for a few centimetres and then thread breaks. Any suggestions?

If you have not already done so, try changing your needles. Sometimes the needles will be slightly bent or dull and cause thread breaks. If this does not help check your tensions. These should be set somewhere between 4 and 6 generally. If one is far out of this range, try resetting it. If you try both these things and still have trouble, it is likely that your machine is out of time. In this situation it would be best to take your machine to a reputable sewing machine repair shop for repair. Retiming a serger can be very difficult for a novice, and can be quite and unpleasant and tedious job, best left to a professional who is well versed in serger repair.

Adjusting tension on overlocker

overlockers and sergers are annoying in that every time you change materials and threads they must be re-tensioned.

Get a scrap piece of material. Thread your machine correctly according to the instructions in your manual. If no manual most sergers are threaded, upper looper, lower looper then needles from right to left. Make sure you thread with the presser foot UP.

You want to balance the stitches Begin by adjusting the looper dials, you want them to meet right at the cut edge. Then adjust your needles. Keep doing test seams until you have them balanced. If you are a novice... try threading with each thread point having it's own color. That will help you identify which thread is giving you fits.

Have fun.

The tension on my montgomery sewing machine is too tight. After it has been adjusted it sews correctly for a few stitches and then tightens back up.

Seems to me these machines were made in Japan and branded by MW... Do some research and see if you can find out who made those machines. Then see if you can get a part direct from the original manufacturer. Seems like it was Janome (or who ever it was before "janome") Good luck.

I have an old Janome Mystyle 30, which is still sewing like a dream, but in the middle of a project, I suddenly can't get the stitch tension right. Of course I can't find the manual either.

Unfortunately Janome don't provide links to their user manuals, so the only option is to buy one. I cannot find any free examples elsewhere, but this supplier has what you need at a reasonable price. If you find that you cannot eventually get the tension correct, then your machine is worn or out of adjustment and will need servicing. A smooth running machine is vital for consistent tension, so make sure that you have cleaned out the lint from the mechanism and applied sewing machine oil as advised in the owners manual.

Hope that I've been of some assistance and that you quickly solve your tension teaser! Please take a moment to rate my reply.

Janome left needle thread breaking CONSTANTLY

Sounds like a tension problem. Your machine should have two tension adjusters. One for each needle. The book that came with your machine will tell you how. Another possibility is a bent needle.

Noise from bobbin case on new Janome 4020

Check the bobbin to be sure it is inserted correctly. When you pull on the bobbin thread the bobbin should turn to the left(orcounterclockwise). If it doesn't, the thread will come out of the bobbin tension and give you loose stitches on top of the fabric. It will also make a noise because the bobbin is bouncing up and will need to readjust your tension again.
