I just written a post on this yesterday I will copy it here for you to follow. Then you'll need to check your hook timing. The bobbin should be centred in between the coloured or upper thread. If the tensions look ok on the back of the design, and by this I mean you have a good balance of bobbin and upper thread on the back of the design. If you see too much of either and no balance then your thread breaks could be caused by tensions issues. Look at the back of the design and see what the ratio of upper thread and bobbin thread is on the back of any design you've just sewed out. The groove that runs from the eye up to the wide part of the needle must fact towards the front of the machine, this will ensure that the scarf is facing the rear. On the other side just above the eye of the needle is the scarf of the needle, a slight indentation cut out of the shaft of the needle.
On one side of the needle there is a long groove that starts from the eye of the needle and goes all the way along the shaft of the needle up to the part where it starts to widen out.
There are two things to look for.ġ) That the eye of the needle is not facing to the left at all, you can have it facing straight on and slightly right but never left.Ģ) You need to ensure that the correct side of the needle is facing the front of the machine.
Inspect the needle, and ensure that it is inserted onto the needle bar correctly.
