Reverse revolution to lift the needle after thread trimming (Function setting No. 56)
This function is used to make the sewing machine rotate in the reverse direction after thread trimming to lift the
needle bar almost to highest position. Use this function when the needle appears under the presser foot and it is
likely to make scratches on the sewing products of heavy-weight material or the like.

(Caution) The needle bar is raised, by rotating the machine in the reverse direction, almost to the high-
est dead point. This may result in slip-off of the needle thread. It is therefore necessary to
adjust the length of thread remaining after thread trimming properly.
