The Singer 411G was a high-end sewing machine when it was introduced. The letter "G" in the model number denotes the fact that it was made in Germany. Many people commonly refer to this machine simply as a 411. Similar machines were produced by Singer with different model numbers that made them unique to the location where they were made. The 411G is just such an example; it is almost entirely the same machine as the Singer 401, which was made in the United States. Setting up a 411G for sewing is a straightforward process.
Wind the bobbin. Disengage the stop motion mechanism in the hand wheel by turning the inner piece clockwise and the outer piece clockwise. Engage the winding mechanism by pulling out the slider located just in front of the bobbin winder. Place a spool of thread on the spool pin and place an empty bobbin on the bobbin winder. Pull the tail of the thread forward to the tension mechanism and draw it through the disks from left to right. Continue pulling the thread to the right and pass by the thread guide that is in front of and slightly to the left of the bobbin winder. Pull the tail end of the thread through one of the holes on the bobbin from the inside out. Fill the bobbin, and then remove it from the machine. Put all mechanisms back to their original positions.
Thread the bobbin case. Hold the bobbin with the thread wound in a counterclockwise manner with the thread tail leading off to the left. Put it into the bobbin case and pull the thread into the slot on the left of the case, leading it under the spring until it is situated in the notch. Slide the bobbin plate closed.
Thread the top of the machine. Raise the needle to its highest position by turning the hand wheel toward you. Put your thread on the spool pin. Guide the tail through the first thread guide to the left of the spool, and then straight down to the next thread guide. Slide thread into the take-up lever located just to the right of the second thread guide. Next, wrap the thread around the tension mechanism from right to left, and then catch it on the hook that is immediately to the left of the tension mechanism. Hook the thread into the thread guide just above the tension mechanism and guide it up to the second take-up lever, drawing it through the slit. Guide the thread back down, passing it through the three thread guides that are situated above the needle. Thread the needle, passing it from front to back.
