Test-sew a buttonhole on a piece of waste material and choose the buttonhole size. 21 buttonhole lengths are stored in the comput er, from 7.0 to 44 mm. On program selection a programmed buttonhole length of 22mm and a buttonhole width of 4.5mm appear in the display. Select the length of the buttonhole with stitchlength keys 7 (Fig. 1). The machine will automati cally sew the selected buttonhole. Before beginning the buttonhole pull the runner of the buttonhole foot fully to the front. 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 width of the area of cut changes auto matically (Fig. 5). A buttonhole width of 4.5 mm is stored. Adapting the buttonhole seam lengths with the balance keys With "balance" keys 5 the left buttonhole sear length can be adapted to the right one. Sew a sample buttonhole first. Example: If the left seam is too short (Fig. 4a) Select +1 to ÷3 with "balance" key, or more, required. lithe left seam is too long (Fig. 4b) Select -1 to -2 with "balance" key, or more, required. • Sew the first buttonhole seam at the require length and • the first bartack. • Press balance keys 5, "+" or"-", and adjust th second buttonhole seam length to the first on (Figs. 4a, 4b). • Sew final bartack. The change made in this way will be mair tamed for the following buttonholes. For programmable linen buttonholes see page 9 Correcting a buttonhole If a buttonhole does not turn out well, cancel it by pressing "pattern start" key 26 and sew it again. 92
