Bringing Up The Lower Thread; Thread Cutter - Husqvarna Viking 3600 Operating Manual

Hold the threaded upper thread and turn the handwheel to
ward you until the needle goes down through the needle
plate, and then up again. When the needle is in its highest
position, pull the upper thread and you will get a ioop of the
lower thread which is easy to catch. You shouldn't pull the
upper thread too hard as this may damage the needle.
Pull the threads about 6" (15 cm) towards the rear. If the
thread ends are too short, the thread-may slide out of the eye
of the needle when you begin to sew.
On the back of the presser bar you will find a notch, the
thread cutter, which makes it easy for you to cut off the
threads.
