How to thread

You may consider installing brand new needles--be sure they are pushed all the way up before the screw is tightened.

Remove all the threads from the machine.

RAISE the presser foot and rethread from the beginning--double verify that the pathway for each thread is correct. If one guide is missed or threaded out of order, the machine will not work correctly

When threading the tension disks, give each thread an extra little tug to make sure it is seated firmly in the disk. Sometimes the thread will actually make a little "pop" when it seats.

Be sure to thread IN THE ORDER specified--if not, the machine will probably never work. Usually, the upper looper is threaded first, then the lower looper. Also, usually the last step in threading the lower looper is to make sure the thread drapes OVER the top of the upper looper before the tail is pulled under the presser foot.

Set all the tension dials to the midway point which is the standard setting for basic overlocking. Each machine varies and may need some tweaking, but this is a good starting point.

If everything has been done correctly up to this point and it still will not make a chain, the machine timing may be off. You may need to take it for service.

Remember, if the machine breaks a thread or will not serge properly, avoid unnecessary frustration and rethread every thread from the beginning in the proper order. Until you understand the machine very well, trying to fish a thread through the machine will fail ~99% of the time.

Be sure to RAISE the presser foot when threading the machine so the tension disks are open to accept the thread. It also helps to grasp the thread between the thread tree and the tension disk and with the other hand grasp the thread below the tension disk and give the thread a little tug to make sure it is seated all the way in the tension disk.

Of course, make sure that the machine is threaded in the proper sequence--check the owner's manual (usually the upper looper is threaded first, then the lower looper and the lower looper thread tail is draped Over the upper looper in the last step before being pulled under the presser foot).

If the thread breaks or comes unthreaded, Best Course of Action is to remove all the threads and rethread from the beginning. Nine times out of ten, trying to rethread one thread will not work!

Also, when removing thread, it is not a good idea to clip the threads between the thread tree, raising the presser foot, and then grabbing the thread tails at the presser foot and pulling all the thread ends down. Threads should not be pulled UP through the tension disks.

rethread machine, make sure u thread all steps

try a new needle--the correct one for the fabric and thread
make sure the top thread has not come off the thread take up lever
rethread the machine top and bobbin-- using every thread guide
make sure the bobbin is turned the right way in the bobbin case
if these suggestions don't help, then taking the machine to be checked would be a good idea.

here's my suggestions
change the needle-make sure the needle is inserted correctly
into the needle holder & also turned the right way
make sure when sewing on the machine that the top thread does
not come off the thread take up lever
check the top thread tension it may be too tight,, usually 4 is good
or if the machine has automatic tension set it there
make sure it's the right needle for the machine & make sure it's the
right needle for the fabric & thread.
some thread is knotty ,,, make sure the thread is good quality

when starting to sew
1.make sure to have a thread tail of 3 to 6 inches on top thread & bobbin
this will keep the thread from pulling out of the needle when starting
2. make sure the thread tail is pulled behind the needle area before starting to sew

Make sure your software is up to date. "Live Update" under "Help" submenu.
If software is updated make sure the upper thread is inside the thread sensor area. Check Machine Tutorial for proper threading.

Deep breath and start at the beginning, make sure the presser foot is up before you thread the machine, top tension should be about 4 or 5, make sure the thread has gone between the discs, make sure the bobbin is turning anti clockwise in the bobbin case, you should only just be able to pull the thread through with slight resistence, if it is too tight loosen the scew on the bobbin case about a quarter of a turn and test, repeat if you have to, remember that Singer machines do not work well with thread that is not mercerised, if the thread is not being pulled through at all then the chances are the machine will need retiming.

Make sure you have your thread through all of the thread guides, If I feel I need a little extra tension I loop my thread through the bobbin tension guide on top of the machine, especially if it is a fine or silky thread for decorative work. Make sure your bobbins are wound tight and also threaded correctly. When freehand quilting you should sew at a moderate speed and make sure to move your fabric smoothly with the speed at which you are sewing, you may just have to practice a bit like I did...If none of this works you may need to take your machine in and have the tension set on the bobbin housing itself..

1. Make sure the needle is up in the machine all the way.
2. Make sure the flat side of the needle is facing the rear of the machine
3. Only turn the handwheel on the side of the machine towards you, never away from you.
4.Double check your threading of the top of the machine.
5. Also make sure your using the proper needle, your machine takes the most common needle on the market but some look like it and are shorter or longer and wont work properly. Also make sure your not buying needles for a singer serger.
