Threading the Machine

To thread the Singer 15-91, start by raising the needle to the highest position. This makes it easier to thread the machine.

Place the spool of thread on the spool pin and secure it with the spool cap.

Next, guide the thread through the thread guides located on the top and side of the machine. Make sure to pull the thread downwards through the tension disks.

Bring the thread up into the take-up lever and back down to the needle.
