Maintenance

Regular maintenance ensures the longevity and smooth operation of your Janome Memory Craft 9450QCP.

1. Cleaning the Machine

Periodically clean lint and dust from the bobbin case area and feed dogs using a small brush. Turn off the machine and unplug it before cleaning. Avoid using compressed air, as it can push lint further into the machine.

2. Needle Replacement

Replace the needle regularly, especially after 8-10 hours of sewing or if it becomes bent or dull. A fresh needle prevents skipped stitches and fabric damage.

3. Bobbin Case Maintenance

Remove the bobbin case and clean any accumulated lint or thread bits. This helps maintain consistent bobbin tension and prevents thread jams.

• Check that the machine is threaded properly, both upper thread and bobbin thread.
• Use the correct type and size of needle for your fabric.
