Question about Kenmore 756A-30BH Mechanical Sewing Machine

When I start sewing my needle stops

Further investigations shows that the thread is bunching in the bobbin compartment. When I turn the wheel manually it looks like the dish holding the bobbin is going to lift out of the machine.

Re: when I start sewing my needle stops

You may be using a wrong bobbin size or you have lint ( fabric fuzz) clogging up the bobbin compartment. Take a pipe cleaner and clean under all the boobinholder sides to clean out. Sometimes even the bobbin getting wound from the spool can wind uneven and create this problem.

Needle dragging in bobbin casing. How do I adjust needle shaft?

Basic Tips for All
  1. Always turn the handwheel TOWARDS you (counter clockwise) as turning it in the opposite direction (away from you, clockwise) may knock the timing out requiring repair from a service center.
  2. Always be sure your presser foot is in the DOWN position before sewing. Sewing with the presser foot in the up position will cause your thread to tangle and your bobbin to jam.
  3. Change needles regularly (after 16 hours of use) as dull/weak needles can cause damage to your machine and fabric. Only use SINGER needles on your SINGER sewing machine.
  4. Always be sure you are using the correct bobbin for your machine. Class 66, Class 15 and Class 15J bobbins look very similar. However, using the incorrect bobbin class in your machine can cause damage.

As you sew thread bunches up in bobbin compartment

Generally, you need to rethread your machine on top. You should probably take the bobbin out and see if it is wound properly. You should change the needle too.

I have a Bernina Activa 130. I tried to sew over some leather, started fine, then the needle got stuck and I stopped right away. Now, the bottom threads keeps bunching. I have re-threaded the machine, new...

You need a fatter needle. The skinny needle will not open the leather enough for a smooth flow of thread and that's why the bobbin is bunching up when the top thread is sticking. Make it easier on your machine by using an appropriate size needle while sewing leather.

I am sewing scout badges on a uniform and when I sew there is a bunch of needle thread bunched up on the bottom (the top looks fine). And the needle thread gets all caught up around the bobbin.

Clean out the bobbin area if there are any thread tangles there.

Refer to the maintenance section of the manual - see the configuration of the bobbin case and shuttle race? The bobbin case as an extending arm and the race a notch. When inserting the bobbin case into the shuttle, turn the handwheel so the needle is at it's highest position. Then lift the lever on the back of the bobbin case and insert the cast into the shuttle, arm pointing straight up toward the bed of the sewing machine.

Now thread the machine with the presser foot up - always - and see if the tangling stops.

When you forget to lift the presser foot before threading the machine, the tension control does not open to capture the thread. Then when you begin to sew, the top thread has no tension, and the bobbin thread, which does have tension, pulls the top thread to the bottom in messy loops.

The fabric gets pulled down into bobbin compartment and thread gets all bunched up hard to remove

It sounds like your bobbin compartment might be pulled out of alignment. You might want to take the bottom plate off, clean off any lint and threads, and put the bottom compartment back in. Follow your manual if you have it. With your right wheel, slowly start to sew is the top or bottom thread having problems? You may have to rethread top and bottom. I found that one time, my top thread was not threaded correctly.

Needle jams and breaks off

Needle jams....Thread is caught in the hook...solution...Remove the upper thread and bobbin case,turn the handwheel backwards and forwards by hand and remove the thread remands.

Needles breaks
1. Needles is damaged..Insert new needle
2. The needle is not correctly inserted....insert flat side towards the back
3. Wrong needle size for the fabric...Choose a needle to suit the thread and fabric.
