Neither the needle up/down or the LED for the stitch selector will work if the bobbin winding pin/holder is pushed to the right (meaning pushed into the winding position). If you accidentally left the winding pin/holder pushed over, you will lose the functions of both the LEAD and the needle up/down button! (Neither of these functions can work while in bobbin winding mode!)

I noticed on a pack of quilting needles it said they stopped skipped stitsches, so maybe you need a different kind of needle with less drag

it's possible that your thread guide may be off some & needs to be adjustedor the bobbin isn't being pushed down far enough on the spindle to click into place to hold good

adjust the top tension up one number at a time & then sew a sample, if it's still loose then increase one more number until you get the desired stitch.

Check your bobbin spindle. If engaged (pushed toward the right) LED will not light. When the clutch knob is pulled out, when you wind a bobbin, the up & down needle will not move. So you must push the clutch knob in again to let the up & down needle go up and down. The clutch knob on my machine is in the large hand wheel upper right side of my machine.

Check your bobbin winder spindle. It may be engaged. (pushed to the right). Push it to the left, if it's pushed to the right and the LED will go on.

Have you got the thread through the take up lever correctly? If its not threaded this will cause the needle thread to be pulled backwards. Just recheck all the threading paths from spool to needle have been done correctly.

Oil any movin g part that you can get to and only a couple of drops of oil before you use it.

Hello

Turn off the power. Remove the accessory compartment located in front of the machine, if applicable.

Open the hook cover that shields the bobbin area. Please note that you do not need to remove the bobbin case.

Locate the drop feed lever near the bobbin case. Some machines have the lever towards the back of the free arm. Press down on the lever and then move it to the next notch or position. The raised metal feed dogs should be visible through the openings on the needle plate. You may need to rotate the big balance wheel one rotation to engage the mechanism on some machine models. The metal teeth will then spring up.

Close the hook cover. Insert the accessory compartment, if applicable.

Turn on the power. Try test stitching a piece of fabric. The raised feed dogs should help guide the fabric under the presser foot.
