Question about White Sewing Sewing Machines
Check: 1 Bobbin is TIGHTLY wound 2.You have put the bobbin in the correct way - the thread MUST unwind from the bobbin as per instruction manual for your particular machine. 3. There is a tail of bobbin thread around 2" long 4. Have a tail of about 4" thru the needle when the needle is in its highest position. 5. Securely hold the neeedle thread down at the rear of the needle plate. 6. Turn the handwheel in the direction it turns when sewing until the needle has gone down and backup again. If you pull on the needle thread now, the bobbin thread will come up. If it does not, you most likely have a problem with the bobbin, the bobbin case, needle to hook clearance or timing of the needle to the hook or a burr on the hook.
----------- Needle in backwards is the most common problem. Remove the needle, rotate 180 degrees and try again. If that doesn't fix it, do the same operation with a new needle. (In general, the flat side of the needle should be to the back of the machine.) Bent or damaged needles also act "out of time", so a new needle, right way around, is a good thing to try. (1) Check the needle or replace with a new one. A needle has a groove in one side of it and that is the side that the thread enters the needle. Some thread from the side and some from the front.
(2) Before sewing, manually turn the wheel to make the needle go down while holding the needle thread with your left hand. When the bottom thread pulls up, pull both threads toward the back of the machine before sewing.
(3) Make sure your pressure foot has been lowered. Sounds silly, but if you loft is high it might just look like it is engaged.
(4) Try it on two ply fabric first and try both a straight stitch and a zig zag and see if you have problems with both.
(5) Make sure your thread is really machine thread and not hand sewing thread.
(6) Make sure the bobbin thread is feeding off the bobbin spool in the right direction.
(7) Anything other than these is probably a tension problem or a timing problem.
