On program selection, a programmed buttonhole length of 22mm and a buttonhole width of 4.5mm 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 toot fully to the front. Correcting a buttonhole If a buttonhole does not turn out well, cancel it with 'pattern start' key 26 and sew it again. Changing the buttonhole width For every type of fabric the corresponding button hole width can be determined up to 5.5 mm. For heavy fabrics select a wide buttonhole and for light fabrics a narrow one. At stitch width keys 8 you can set the required width. The length of the cut changes automatically (Fig. 5). The stored buttonhole width is 4.5 mm. 2 Adapting the buttonhole seam length with the balance keys With "balance" keys 5 the left buttonhole seam length can be adapted to the right one. Make a sample buttonhole first. Example: If the left seam is too short (Fig. 4a) Select balance +1 to +3 with key 5, or more if required. If the left seam is too long (Fig. 4b) Select balance -1 to -2 with key 5. or more if required. • Sew the first buttonhole seam at the length required and • the first bartack. • Press balance keys 5, "+" or"-", and adjust the second buttonhole seam length to the first one (Figs. 4a, 4b). • Sew last bartack. The change made in this way will be main tained for the following buttonholes. 84
