Needle precautions Be sure to observe the following precautions concerning the correct choice of needle for your machine. CAUTION ● Your machine is designed to use household embroidery needles. The factory recommended needle is "HAX 130 EBBR" (Organ). Schmetz needles 130/705 H-E may be used as a substitute. Use of any other needles may break the needle or thread or damage the needle- threading mechanism or result in injuries. ● Never use bent needles. Bent needles can easily break, possibly resulting in injuries. 2 Checking the needle Sewing with a bent needle is extremely dangerous since the needle may break while the machine is being operated. Place the flat side of the needle on a flat surface and check that the distance between the needle and the flat surface is even. If the needle is bent or the tip of the needle is broken, replace the needle with a new one. (Refer to "Changing the Needle" on page 63.) ■ Good needle Needle type marking Flat side ■ Bad needle If the distance between the needle and the flat surface is not even, the needle is bent. Do not use a bent needle. Flat surface Flat surface Bobbin precautions Be sure to observe the following precautions concerning the bobbin.

Use of any other bobbin may result in injuries or damage to the machine. COATS L Polyester ● Use a bobbin thread that has been correctly wound, otherwise the needle may break or the thread tension will be incorrect. ● When winding a bobbin, only use optional bobbin winder (refer to page 188) and metal bobbins (Parts Code: 100376-053). ● When winding the bobbin, be sure to use cotton or spun polyester bobbin thread (between 74 dtex/2 and 100 dtex/2).
