Singer 4411 will not pick up bobbin thread.

Do you mean the Singer 4411 Heavy Duty sewing machine? If so,
first place the spool on the spool pin with an appropriate sized spool holder, if you are starting the project. Snap the thread into the thread guide to the left of the of the spool pin. Wrap the thread clockwise around the bobbin winder tension discs (slightly to the left and forward of the thread guide). Bring thread towards the bobbin spindle. Thread the bobbin (put the thread through the hole in the bobbin). Place the bobbin on the spindle with the hole up. Move the bobbin spindle to the right. Hold onto the thread above the bobbin and step on the foot control pedal. When the bobbin finishes winding the thread, cut the thread at the top of the bobbin and the incoming thread from the spool. Move the bobbin spindle to the left and remove the bobbin. If you have already threaded the machine for sewing, you will need to remove it from the various guides and tension discs that are used in sewing. Then after winding the bobbin, re-thread the top thread.

The directions to wind the bobbin are in the manual on page 12 (page 19 of the PDF). You can find many Singer manuals at the Singer support page: https://www.singer.com/support . The 4411 support page is https://www.singer.com/search/support?lp=support&title=4411 . The current link to the manual is https://www.singer.com/sites/default/files/product_manual/SINGER%204411%20Heavy%20Duty%20Sewing%20Machine.pdf .

I hope this helps.

Try a brand new needle. Verify that the machine is threaded properly--both upper and bobbin threads.

If it is still not picking up the bobbin thread, it is likely there is a needle/hook timing issue requiring service.

...

First, install a brand new needle and verify that it is facing the correct way and it is the proper needle for your machine.

Confirm the bobbin has been installed in the bobbin case so it is unwinding the bobbin the proper direction as you pull the bobbin thread.

Six Common Sewing Machine Problems Solved

If it still will not pick up the bobbin thread, open the bobbin area of the machine and watch the needle action as you hand-turn the handwheel. You may see why it is not picking up the thread because the needle could be arriving too soon or too late to intercept the bobbin thread. If this is happening, the needle/hook is out of time. Take it for service.

..

Make sure you are using a brand-new needle. A bent or damaged needle may not pick up the bobbin thread.

If you can watch the needle/hook action (open the bobbin are and hand-turn the handwheel), you may see that the timing is off. There are many web sites and videos online that explain tweaking the timing.

...

try tightening the needle thread tension as it appears to be too lose
try loosing of the bobbin thread tension a fraction as it may be to hard to pull out of the bobbin case under the spring
changing thread sizes and material thickness generally requires a tension adjustment of the threads

you oil it in the center of your bobbin case, also theres a small pad like thing just above your needle , there as well as inside your threading area where the spring is

Understanding Thread Tension Threads

Be sure to mark the tension screw setting on the bobbin BEFORE you make any adjustments so you can reverse the changes. If you sew a lot of heavy fabric, it may be worthwhile to buy an extra bobbin (they aren't that expensive). Then set one bobbin for heavy thread and keep one for regular thread. Makes it a lot easier to go from one to the other without fiddling with tension screw adjustments.

...

If you've threaded the bobbin per instructions... then make sure your needle isn't damaged, bent, or dull. Also make sure the needle is seated fully and correctly oriented into the needle bar.
