The Singer Touch & Sew Model 604 sewing machine was marketed as one of the first sewing machines to combine the three most often used types of stitches. Those three stitches were the straight stitch, zigzag stitch and chain stitch. The Touch & Sew line of machines was first introduced in 1965. As an added convenience the machines offered a two-piece, screw apart bobbin that was wound in place in the bobbin assembly by the machine at the push of a button.
Unscrew the two halves of the bobbin reel and remove any leftover thread. The bobbin must be empty before winding new thread onto it. If you do not wish to remove the bobbin, execute step 2 and then pull the remainder of the thread until the bobbin is empty.
Press down on the reel wind button. The button is located on the bed of the machine. This button toggles the machine between winding the bobbin and sewing.
Press the pedal and thread will be wound onto the bobbin. Continue pressing the pedal until the bobbin is full.
Push the reel wind button to the left and it will pop back up into the sewing position.
Turn the hand wheel to lower the needle and pick up the bobbin thread. Once raised, pull both the bobbin and needle thread towards the back of the machine and allow approximately 6-inches slack. You are now ready to sew.
