On program selection, a programmed buttonhole length of 22 mm and a buttonhole width of 5 mm appear in the display. Select the required length of buttonhole with stitch-length keys 7 (Fig. 1). The machine automatically sews the selected buttonhole. Before beginning the buttonhole pull the runner of the buttonhole foot fully to the front. For the following buttonholes it is best to lift the fabric a little in order not to affect feeding. The sewing speed should always be the same. Correcting a buttonhole If a buttonhole does not turn out well, cancel it by pressing "pattern start" key 26 and sew it again. Adapting the buttonhole seam lengths with the balance keys With 'balance" keys 5 the left buttonhole seam length can be adapted to the right one. Sew a sample buttonhole first. Example: If the left seam is too short (Fig. 3a) Select balance +1 to +3 with key, or more if required. If the left seam is too long (Fig. 3b) Select balance -1 to -2 with key, or more if required. • Sew the first buttonhole seam at the length required and • the first bartack. • With balance keys 5, -i-" or "-", adjust the second buttonhole seam length to the first one (Figs. 3a, 3b) • Sew last bartack. The change made in this way will be main tained for the following buttonholes. 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 E 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. 4). A buttonhole width of 5mm is stored. F L
