FAQs

How do you wind the bobbin correctly?

Place the bobbin in the bobbin case with the thread feed clockwise as shown, then position the case into the shuttle and release the latch. Draw the thread through the case slots and tension spring, mount the bobbin on the winding spindle until it clicks, start the machine, and wind until the bobbin stops before removing it.

What should you do when stitches are skipped?

Insert the needle properly, replace a bent or worn needle, and rethread correctly. Use the recommended sewing needle and thread for the fabric, ensure proper needle bar height, and check needle timing and clearance between needle and hook as referenced in the mechanical adjustment sections.

What causes upper thread breaking and how is it fixed?

Common causes include sewing too fast, an incorrect thread path, bent or dull needles, and excessive upper thread tension. Use the proper thread path, start with medium speed, replace the needle, adjust upper thread tension correctly, and replace or repair worn parts such as the needle plate hole when needed.
