I did have to unscrew the knife block in order to rehook the pushrod, once I changed the knife. The pushrod would not budge forward, nor could I move the knife back far enough, (last 1/8th inch probably) to lift it over the pushrod hook onto the hole. I then test sewed a small design and got no top trim, but the lower thread did trim. Progress? I saw in the cd maintenance booklet, they talk about a "housing unit" to adjust the trimmer. Is that something I need to do now? =========================================================== The AmayaUsers Mailing List Website: http://www.amayausers.com Discussion Board: http://www.amayausers.com/boards Subscribe/Unsubscribe: http://www.amayausers.com/list ===========================================================
