Bernette FunLock b44 OverLock Serger Machine

I love this machine. However there was a problem when it got here and through fault in the design of the machine, not World Weidner. On the front of the machine the door that comes downs that so you can thread it has storage for the small utensils that you use with the machine. In transport, the screwdriver came loose and slid over to the left underneath where the needles come through the machine. Consequently, the machine would not sew correctly until I figured out what the problem was. It was difficult to remove the screwdriver, but I was able to do it. I liked that they were trying to help by threading the machine and leaving the thread so I could tie on new ones and pull them through but with the trouble with the screwdriver, I had an instant lesson in threading on my own. Machine has worked wonderfully since.
