Necchi BU MIRA threading

Hello ruth,
From the spool pin take the thread to the guide above the tension unit, round the guide and straight down the right hand side of the tension unit and round the left inbetween the discs making sure the spring clicks up when when you pull the thread up, straight up to the takeup lever and thread right to left, follow the guides all the way down to the needle and thread front to back. MAKE SURE YOU HAVE THE PRESSER FOOT UP AND THE TAKEUP LEVER TO THE TOP WHEN YOU THREAD THE MACHINE
