Carol, Our tech guy stressed that that area be kept clean of lint, thread ect. He recommends using the Ultra Duster that is sold in the Elect. of W. M.. Our Big Lots also carries it. He also strongly recommends to take the bobbin out, but not to remove the entire bobbin area, as it can be very difficult to get it back correctly. I just clean it thoroughly, and do as he says; don't take it apart!
