Upper Threading This section describes how to position the spool for the upper thread, and then thread the needle. 1 a a Mark on handwheel If you use threads other than those listed above, the pattern may not turn out correctly. CAUTION ● When threading the upper thread, carefully follow the instructions. If the upper threading is not correct, the thread may become tangled or the needle may bend or break. ● The needle threader can be used with a 75/11 through 100/16 home sewing machine needle. When using special thread such as transparent nylon thread or metallic thread, the needle threader cannot be used. ● Thread with a thickness of 130/20 or thicker cannot be used with the needle threader. ● If the needle threader cannot be used, refer to "Threading the needle manually (without using the needle threader)" (page 42). ● Never use a thread weight of 130/20 or lower. About the spool of thread Information about the spools of thread is described below. CAUTION ● If the spool or the spool cap is not positioned correctly, the thread may become tangled around the spool pin or the needle may break. ● Three spool cap sizes are available, allowing you to choose a spool cap that best fits the size of spool being used. If the spool cap is too small for the spool being used, the thread may catch on the slit in the spool or the needle may break. Upper Threading 37
