Now, only the left upper segment of the buttonhole symbol is flashing (Fig. 3). The machine then automatically sews the first bartack and the return seam (Fig 2b). Shortly before the end of the seam the machine sews slowly, stitch by stitch, in order to draw attention to the last bartack. One zigzag stitch before the end of the first buttonhole seam. • Press key 19 again. The second bartack is now sewn and tied off (Fig. 2c). (Both segments of the buttonhole symbol are off, Fig. 4). Now the buttonhole is stored. Without having to actuate further keys, all following button holes can be sewn automatically. Adjusting the density of buttonhole seams With stitchlength keys 7 the buttonhole seams can be set more densely or loosely. The stored buttonhole density is 0.5 mm. Make a sample buttonhole first. 2 Changing the buttonhole width For every type of fabric, the corresponding but tonhole width can be determined up to 5.5 mm. For heavy materials select a wide buttonhole and for light materials a narrow one. With stitch width keys 8, you determine the required buttonhole width, The length of the cut changes automati cally (Fig. 6). A buttonhole width of 4.5 mm is stored. Adapting the density of the left buttonhole seam to the right one With "balance" keys 5 the left buttonhole seam can be adapted to the right one. • Sew the first buttonhole seam at the required length and the first bartack. • Press 'balance" keys 5, '-i-" or "-", and adapt the second buttonhole seam to the first one (Fig, 5). • Press "pattern start" key 26, Afterwards program the buttonhole as described on this page. Make a sample buttonhole before you sew buttonholes on a garment. Note: If the buttonhole seams of the stored but tonhole do not coincide, make another correction at "balance" keys 5. Adapting the seam lengths of stored button holes with the balance keys, see page 80. 82
