When changing the repeat on a standard embroidery machine, needles, borers and shuttles have to be changed manually. All the required needles, borers and shuttles have to be set or removed according to the working repeat. Needles can be removed or set by opening or tightening a screw, and borers, by opening or closing a hook.
Standard machines have one single thread roller that feeds the needle. Do not forget to remove the corresponding spool when changing the repeat.
If the shuttles remain in the machine although not in use, the shuttle yarn will be tangled and it will be impossible to continue stitching afterwards.
