SOURCE: Machine not sewing

Make sure you have threaded the machine from right to left, it sounds like the needle thread is trapped under the lower looper thread and cannot form a stitch.........start the threading over from scratch like this:

  1. Lower Looper
  2. Upper Looper
  3. Left Needle
  4. Right Needle
Is there a diagram for how to thread on the inside of the door ?

Follow that slowly and carefully to make sure you have not missed any thread guides on the way, as each one needs to be followed through to ensure correct tension and thread progression.

If you are certain that all threaded correctly, did you have a fabric jam and pulled it loose ? If so, the timing may well be affected.

Post an update and we'll get this right.

SOURCE: thread tension dial on riccar sewing mach. needs repaired

Please, tell me, is the main spintle, still on the machine, or it came off with the rest of the parts?

If you can put the tension parts, the one next to the other in front of the machine, and upload a photo for me, it will be very easy to explain how to put them back.

SOURCE: Upper thread knots up with bobbin thread when sewing a stich

Thread test
Test your thread quality to start, thread your machine and LIFT the presser foot (this opens the tension disks). Pull your top thread straight back. If you feel no tension no mater how much thread you pull, your thread is good. If that your machine passes that test, then let me know, we can go to step 2. If not, try different spool of thread, same test until you get a smooth pull (tip: always check your thread this way when you thread your machine)
Step 2:
Pull on your threaded bobbin thread while it’s in the machine. Does it pull smooth and even? If so, go to step 3. If not, try a new bobbin (bobbins get bent or distorted if wound too tight).
Clean thoroughly in the hook and bobbin case area and oil 1-2 drop is all.
Thread knotting on the bobbin can be a lot of things but here's some guidance:
Tension:
If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on toip and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension)
Jamming bobbin case:
If it is damaged from turning out of place once, it could have rough spots on it that makes the thread hang on it, and keeps making it turn over and over. Use a finger nail board (fine sanding) and smoothall rough spots. Then reset the bobbin case taking care to put the notch in the bobbin case in alignment with the proper spot in the machine (basically 5 o’clock) when looking at the round area where the bobbin case goes.

SOURCE: sewing machine thread nesting

I have fixed it now the bobbin case didn't seem to stay seated during sewing or tangling i should say!. I decided to change the needle and from then on everything worked fine.

I have bought new needles for my Riccar overlocker now the stitching is loopy and messy


Verify you are using the correct needles for your machine. Some needles vary by a fraction of an inch but will make a big difference in serging success.

Remove all the threads from the machine.
(Always cut the threads below the spools, raise the presser foot, and pull the threads DOWN through the needles--Never pull up!)
ALWAYS RAISE the presser foot when threading.
Be sure to always thread each thread in the proper order--threading out of order will usually fail.
Rethread from the beginning and give each thread an extra little tug when threading the tension disk.

If a thread breaks, it is usually less frustrating in the end to remove all the threads and rethread from the beginning. Trying to rethread a broken thread will most likely cause problems.

On rmy riccar sewing machine..After I sew a seam the top stitch seems fine, but underneath the thread is all bunched up in a wad.


increase the needle thread tension
the term is bird nesting and is caused because the needle thread is not pulling the bobbin thread up

Riccar reliant 505 I need a manual for above sewing machine. Can you help? Regards Jane Henry


Have you tried the Riccar site?
http://www.riccar.com/help/manuals/
I couldn't find one for your specific model number.
Have a look at a few of the manuals with similar model numbers. Or try to find a manual that most closely resembles your machine.
Usually sewing machines by the same brand are very similar and thread the same way etc.
Hope this helps!

Try looking for a manual for your machine here.
http://www.riccar.com/help/manuals/
If your model number isn't listed try looking for a similar model or the number nearest to your machine.
Usually, sewing machines of the same brand thread in the same way. Hope this helps!

Riccar sewing machine keeps breaking thread makes about 4 stitches and then the thread breaks. GRRRRRRRRR.


Oh yes. GRRRRRR is the word!!! I hope I can help.

In many cases, breaking thread is caused by the upper tension being too tight, so that's something to check.

Another thing is to change your needle. If it's at all bent it can break the thread.

Third thing is to make sure you're using new, high quality thread. Older thread breaks more easily, especially if it's been in the sun.

Finally, clean and oil the machine. A bit of lint in the bobbin area can do all kinds of havoc.

Hope this helps!!

I have a very old Riccar 440 model sewing machine which although is in very good condition, has not been used for many years!! We have lost the original manual and when we have tried to use it the thread...


Glancing through the manuals at Riccar's website I do not find a model 440, though there are models 404, 410 and 414. One of those manuals is likely close enough. While it could be a tension problem, breaking thread is usually a result of a damaged or incorrectly placed needle. Also, if you are using old thread, it may no longer have the strength necessary. The first thing to do is replace the needle with a fresh one, making sure that the flat side is to the rear of the machine, and that the needle is fully inserted. It's also a good idea to remove the feed dog cover plate and remove any buildup of lint. Also remove any lint that may be in the area around the bobbin case and hook. Here is a link to the Riccar site where manuals can be downloaded: http://www.riccar.com/help/manuals/
Please let me know how this goes, I think we can get you sewing without taking the machine in for service.

RICCAR MODEL 210B


I have a Riccar 210B sewing machine. It is about 37 years old. I have been the only owner and up to yesterday it was working fine. Today the motor seems to have quit.

Is the motor repairable? The tag on the motor says YM-40 80W 115V.

Thank you, Susan in Kailua-Kona HI
