I am a new owner of a kitchenaid artisan mixer. Made soft pretzels this weekend and the recipe said to knead in my stand mixer at medium speed. I followed these directions, not realizing that my KA guide said not to exceed level 2. I kneaded at level four for about four minutes, and the mixer was shaking and moving all over the table. My question is: have I ruined my new mixer??? I'm concerned after reading my instruction manual (should have done that beforehand obviously!!) warning than any kneading exceeding level 2 is dangerous to the machine.
