Sometimes you may be concerned about irregular thread tension or perhaps the thread cutter is not working properly. This is often a sign that it is time to clean your machine again.
The following five tips show how you can do something good for your machine:
Traces of fabric, thread and dust get left behind on the machine, including on the inside. The more you sew, the more residues there are. These have a negative effect on thread tension and on the sewing results. Cleaning should be carried out more often when embroidering, when the machine operates at high speed for a long time.
Therefore, clean and oil the machine either after a project or before the next project. If a project continues over several weeks, you should also clean and oil the machine during the project.
Videos on cleaning and oiling your machine can be found under "Video tutorials" on the page for your machine model.
It is best to clean the hook, the hook race cover, the hook race and the bottom of the hook with a clean, dry microfiber cloth, as oil and lint create sticky residue that cannot be removed with a brush. Wipe the hook from the front and back with the microfiber cloth, and also the folded out ring-shaped black hook race cover.
However, a brush is better for cleaning under the stitch plate.
There are several methods for reinserting the hook. You can see an example here. It is important to position the hook correctly on the hook race ring: the left tip of the hook must line up with the left tip of the hook race ring. When the hook race ring is folded up, the hook is moved magnetically into the correct position and clicks into place.
Thread remnants or lint can result in the thread no longer being cut correctly or not being cut at all when the thread cutter is activated. This makes it all the more important to clean the thread catcher regularly.
First remove the presser foot, the needle and the stitch plate and lower the feed dog. Then go to Setup and select "Machine settings", "Maintenance/Update" and "Thread catcher cleaning".
A step-by-step guide appears, whereby it is important to always follow the order. For example, if the thread catcher is already extended but the needle has not yet been removed, it will be in the way.
Please do not use compressed air to clean your machine or the thread catcher as this can blow dirt into inaccessible areas of the machine that can only be removed by a technician.
A microfiber cloth and brush are sufficient.
Of course, you can also have the machine professionally cleaned by a specialist dealer. They will also clean areas that are not accessible to you.
