SOURCE: Help, Janome Ezy Lock 304D Overlocker!

Although the tension units on your machine are of a different configuration, always thread from the right spool first and then each one to the left.........ONLY in that sequence !

now take a look at this sewusa site for a better view of the actual routine through the thread guides.........as I say, the tension units are different, but the sequence is the same, just use the image from above to see which one is next........this chart, just as the one on the fold down cover of your machine need to be followed one thread at a time from R to L

SOURCE: lower looper threader

check to make sure it is not wraping around the upper looper. just stitch without the material and you will see it. but then you must rethread the upper looper and the lower looper again in the right order. hope this helps

Bernina 335 serger won't sew/overlock. carefully rethreaded the serger but that hasn't helped.


The 335 has a two thread chain stitch (stitch type 401), and the overlock side (right needle side), is a three thread plain overlock. If you are describing the plain overlock as the problem, I would first suggest the following in re-threading:

1. Thread the upper looper
2. Thread the lower looper
3. Thread the needle last (important)

If the needle threaded, you cannot re-thread the lower looper without breaking the thread.
In order to thread the lower looper, the lower looper must pass by the needle thus picking up the needle thread. So, instead of threading the lower looper thread underneath the needle thread, the looper would be threaded on top and cannot sew without breaking the thread.
Make sure that the threads are bedded between the tension disks. Check this by stretching the thread fore and aft of the tension disks as well as visually noting that the threads are not accidentally threaded behind the disks. You can also loosen the tension disks when threading so as to allow the threads to bed deeply between the disks.
Please reply with your observations.

Threading an overlocker


Many things can cause the thread to break on a serger. Timing, position of the thread guides, poor thread, and improper tension. One common error is the failure to thread it in the proper order. If the needle are threaded before the lower looper they will cut your looper thread.

Problem with an overlocker that does not overlock


You may need to rethread all the threads because most sergers need to be threaded in the right sequence. I looks like this one has to be threaded starting at the right and progressing left.

Can I just change the needle plate on my janome overlocker been told I need to have loopers reset


Sergers are funny things. You can certainly try just replacing the needle.... make sure you thread correctly. upper looper, lower looper, right needle left needle... etc.

Before you take off sewing... run the machine by hand a few revolutions if it seems to be moving with no more clunking etc. try to sew. If it breaks the needle again. Stop immediately and take it in.

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.

Janome 9200d HAVING PROBLEMS SETTING TENSION. PUT SETTING AT 3 AS RECOMMENDED BUT THE LOWER LOOPER KEEPS SNAPPING.


I presume you mean that the lower looper thread is breaking; are you sure that the thread is not snagging somewhere on the aerial, on the thread stand or on one of the thread guides? Is the aerial fully extended? You need the clearance so the thread can flow off the cones quickly.

Also, some overlockers have a little slide device on the lower looper to make threading up easier, you slide it over to access the thread guide, then slide it back into position to stitch. Is yours like this; and if so, is it back into the right position.

If you are absolutely certain that your threading up is correct then I'd be looking at the tension dial on the lower looper. Give it a clean, reseat the thread into it, and test if it is tensioning correctly. Pull the thread from below the tension on 3, then turn up to 5 or 6, does it feel significantly tighter to pull? Turn down to zero, does it pull through easily?.

If the above doesn't resolve the issue, then perhaps time for a professional service, perhaps the tension device is faulting or the timing is slightly out.

The needles on my Janome 9102D keep breaking


I had a similar problem with my machine. What I've started doing with mine is setting the stitch length at 3 and the differential feed ratio at 1.0 then I set all 4 thread tensions at 3. I thread the machine from right to left, and then when everything seems to be working okay I take scrap material to test the tension and then set them to suit the material I'm using. Right now I'm working with a twill so my settings are 4-4-5-5. This seems to have stopped the thread slipping off the bottom looper and I haven't had any more needles break. I hope this is helpful.
