The step by step sawing of the buttonhole is now effected as follows: 1. Sewing the lefthand bead. Start the machine, then the lefthand bead is sewn in backward stitch. A scale on the buttonhole presser foot serves for determining the length of the buttonhole. After the desired length of bead has been reached, stop the machine. Always take care that the needle is then up. 2. Sewing the first end stitches. For this purpose take hold of the zig-zag lever 12a, give it a strong push to the left until it comes against stop II (Fig. 38). Then sew a few end stitches after that, stop the machine again and set the needle up. 3. Sewing the righthand bead. Bring the zig-zag lever 12a back from the iefthand stop 11 to the righthand stop I (Fig.39). Start the machine again. Stop it again a few stitches before the righthand bead has become as long as the lefthand bead and set the needle up, 4. Sewing the second end stitches. Again set the zig-zag lever 12a to the stop II (Fig. 40), After a few stitches have been sewn, stop the machine once again, and set the needle up as bcfure. 58 3 on) He. 38 ♦ I• 1. 1 ; I Fig. 39 3 0)" I F04. 10 59
