Once you have the cover removed you will be able to access the adjustment screws for the
moving knife. Loosen the screws as indicated in the photo below and move the moving
knife with your fingers until you get it 1 mm from the edge of the fixed knife. Re-tighten
your adjustment screws and press the thread-trimming button on the machine and re-check
the adjustment. You may have to do this more than once to achieve the correct position.
Re-install the arm cover and the needle plate and your finished.
If you find that the machine will still not cut the thread cleanly, you might want to add
two knife shims underneath the moving knife. If that doesn't work then you will probably
need to change both of the knives.
