With stitch wid keys 8, you determine the required buttonhc width. The width of the area of cut changes aut matically (Fig. 7). The stored buttonhole width 4.5 mm. 1 53a = buttonhole with wedge tack 1 53b = buttonhole with lengthwise tack 153c = buttonhole with crosswise tack The buttonhole must be 3mm longer than the dia meter plus thickness of the button. The distance from the edge should be the same measure as the button width. First mark the spacings and the distance from the edge, then mark the buttonhole towards the inside from this point. Sewing is always begun from the inside outwards. 19 buttonhole lengths are stored in the comput er, from 7.0 to 40 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. Adapting the buttonhole seam lengths with the balance keys With "balance" keys 5 the left buttonhole sea length can be adapted to the right one. Sew a sample buttonhole first. Example: It the left seam is too short (Fig. 8d) Select +1 to +3 with "balance" key, or more, required. It the left seam is too long (Fig. 8e) Select -1 to -2 with "balance" key, or more, required. Correcting a buttonhole If a buttonhole does not turn out well, cancel it by pressing "pattern start' key 26 and sew it again. 106 .+-'- .+ - .-" . "- -.-.- ;---.-:,;
