My machine was just over 200.00 when I purchsed it last year in May - 2009. But now I see it is much less.
Anyway's I use canned air, but there is a time where my machine sews correctly and then this breaking click sound occurs in the middle of sewing anything, when I have checked the bottom of my quilt, curtains - anything - the bottom seam looks as though it is french braided.
I took apart the cover plate and blew canned air into it, but it still does this after I have been sewing for about ten minutes.
This is my first machine and it worked so well at the beggining.
I have tried to adjust the tension, but even after finding the correct tension; it will end up the same way on the bottom seam eventually. Leading me back to the original tension setting.
