Basic procedure to sew stitches

While the machine is in operation, pay special attention to the needle location.
In addition, keep your hands away from all moving parts such as the needle and handwheel, otherwise injuries may occur.

Do not pull or push the fabric too hard while sewing, otherwise injuries may occur or the needle may break.

Never use bent needles. Bent needles can easily break, possibly resulting in injuries.

Make sure that the needle does not strike basting pins, otherwise the needle may break or bend.

First, perform a trial sewing, using a piece of fabric and thread that are the same as those used for your project.

Prepare the appropriate needle and thread for the type of fabric.
For details, refer to "Combination of fabric, thread and needle".

If necessary, replace the needle.
For details, refer to "How do I change the needle?".

For safety and best sewing results, use thread and needle appropriate for the fabric that you wish to sew.
If the combination of the fabric, thread and needle is not correct, it may cause sewing problems or result in a poor finish to your sewing project.
Wind thread onto a bobbin, and then install it into the machine.
For details, refer to "How do I wind the bobbin?" , "How do I install the bobbin wound with thread?".
