How to Thread Necchi Sewing Machine

Even though your machine is probably a different model, machines generally thread the same.

Something that may help is ALWAYS RAISE the presser foot when threading the top thread. This allows the thread to seat fully in the tension disk and helps eliminate those loose threads under the fabric.

If the bobbin thread still just lays on the fabric, the top tension is too loose. Tighten the top thread tension so it will pull the bobbin thread up into the fabric. Tension is a tug-of-war between the top and bobbin threads. Neither should win nor lose. Tension is accurate when both threads meet in the middle of the fabric. Also, keep in mind that tension is not static, ie it will most likely need to be adjusted whenever you begin a new project because the thread, fabric, needle, and stitch selection can change the tension.

You shouldn't need a separate spool for the top thread if your machine has the vertical spool pin. Most spools will work unless you are trying to use the huge spools that are made for sergers. In that case, you can wind thread onto a bobbin and then use the loaded bobbin as your top thread--in effect, you would wind 2 bobbins, one for the bobbin thread and one for the top thread. If my thread spools are taller than the spool pin (causing the spool to flop around when I stitch), I simply slip a plastic drink straw over the spool pin and, Voila!, the spool pin is taller than the thread spool.

Another helpful hint: AVOID using old or bargain bin threads. Quality thread will limit a lot of sewing problems and frustration.

Install a brand new needle every 8 hours of sewing time. Frequently, problems are a result of using old, damaged, or dull needles. When having problems, the first course of action is replace the needle. A lot of time can be spent trying to find resolutions to a problem when a brand new needle is all that's needed. If you hear the needle strike something strange, it's probably best to replace the needle as it has probably been damaged or bent. A hard strike of the needle can knock the machine out of time which would require a visit to the service repairman.

Second step to problem resolution--rethread the machine. Remove the thread completely from the machine and start over from the beginning. Verify the thread path is correct.

Also, using the correct needle type and size for the project is important. Don't use needles whose eyes are either too small or too large for the thread. Use a needle made for the type of fabric and project. Use embroidery needles when embroidering, use ball point needles for knits, use sharps (universal, microtex...) for woven fabrics, leather needles for leather, denim needles for denim/heavy fabric, etc.

Last but NOT least, perform maintenance on your machine every 8 hours. Clean lint and loose threads from the bobbin area, the feed dogs, and under the needle plate. OIL (use good quality sewing machine oil) and apply just a drop or two every place according to the manual. Do NOT use 3-in-1 oil, cooking oil, motor oil, WD40 or any oil other than fresh, good quality sewing machine oil!

TTN tension, take up, needle.
Beginning with the spool, guide the thread through the thread guides to the tension assembly. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.) If it passes this test, continue up through the take up lever,then down through the thread guides to the needle. Make sure your needle is fully inserted and turned the correct way.( If you load your bobbin case from the left side,the needle rule is normally FLAT to the RIGHT is RIGHT. There are some exceptions. If you have a newer style drop in bobbin or your bobbin case loads in the front then the rule is FLAT to the BACK.

Try moving the stitch length dial to 4 or 5 - check the manual. You may have it in the position for very close together sewing. I had to do a lot of trying with my 4795 to get it to work right. I found that very thin thread, polyester kind, broke at the needle after a couple of stitches. I switched to coats & clarks thread and a Singer ball point needle and it works fine. Be sure your needle is inserted with the flat top toward the back of the machine. Good luck!

From the reel pin take the thread to the left and over the top thread guide above the takeup lever, make sure the takeup lever is up and and make sure the presser foot is up, take the thread straight down and round the right hand side of the tension unit and back up the left hand side to the takeup lever, thread the takeup lever right to left and take the thread down any guides to the needle, if the bobbin case goes in the front thread the needle front to back, if the bobbin case goes in the side thread the needle left to right.

Necchi 575FA how to put the bobbin spool in the case?Bobbin mats up with a lot of threads on the bottom stich.

The problem most likely is not the bobbin. The problem is the top thread. If thread is knotting, tangling under the fabric, it is a top thread problem.

Remove the top thread from the machine. ALWAYS RAISE the presser foot and rethread from the beginning.

If there are still thread clumps under the fabric, you will need to increase the top tension. (The extra thread appearing under the fabric is excess top thread hanging up under the fabric.) You may need to keep adjusting the top tension until both top & bobbin threads meet in the middle of the fabric.

I have necchi sub22 and the thread keeps coming out

Does this happen with every spool of thread? If so, you either aren't starting the seam correctly or have slightly misthreaded, or the machine is in need of adjustment. See: Thread the machine with the presser foot up. Put it down to sew. Hold both the bobbin and top thread ends together behind the presser foot for the first few stitches of each seam -- then you can drop and sew normally. Not all machines need to have the thread ends held, but enough do that you might as well get in the habit.

Help! I'm having problems with my Necchi Lydia 3. Firstly when threading up, the threaded needle refuses to draw up the bobbin thread. I've followed the instructions and the needle comes in and out but...

try a different bobbin
make sure the bobbin in turned the right way in the bobbin case
also the machine may have a timing problem, and having it checked to would be a good idea.
