Hi. I have a new overlocker. Fabric got jammed ,got it out but machine now jams at half turn . Could some fabric still be under feed dogs ? How to get it out ?

When threading or removing the threads from the machine, ALWAYS RAISE the presser foot! This releases the tension disks so the thread will move freely. AND ALWAYS pull the thread DOWN through the machine, NEVER UP!!!

Hello Jenny hornsey

This may sound traumatic, but there is no easy way to pin point where the tie-up is located. So proceed as follows.
Cut all the threads as they come off the antennas.

Open the front cover and pull-out all the threads by pulling them straight toward the back. If they do not come easily, try moving the hand wheel back and forth by a 1/4 revolution .. this is like a rocking motion. If still not budging, start cutting back the threads and removing them in sections until all the threads are cleared. If this step is still challenging; check that there is no residual fabric or threads still wrapped around the loopers or other part/s of the serger. If so cut them out bit by bit until everything below is cleared.

Great. Now check for threads wrapped and/or jammed anywhere above.

Since the overlocker jammed, it is possible that the needles were bent. This will continue to cause issues in stitch formation. So just to make sure; change the needle/s. Make sure that the correct needle type is being used. Every overlocker is engineered to be used with a specific needle type. The needle type will be specified in the manual and will also appear on the needle package. If the needle types are not the same, do not use those needles.

Re-thread the overlocker and stitch test on a piece of fabric before pressing down on the foot control.

This should get the overlocker back on track and you back to overlocking.

Please let me know how this works out for you.

Happy overlocking
