You are adjusting the head height. Doing so is going to make the attachments either sit too high or rub the bowl. I don't think this is the proper fix for a loose head. You'll need to tighten A DIFFERENT SCREW that you will find by tilting the entire mixer and adjusting it from under the base. That video is here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-D7oji_SJ5PA.html. After this, you probably should verify the head height is correct (using the screw you were twisting in your video to adjust the head height if needed): ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0dpMCjFAiBI.html
Great information! Thanks for sharing. I just made bread a couple of days ago and the mixer performed better than it ever has, however I will be sure and check that bottom screw as well before the next use.
