I’ll tell you about a cool trick you can use in analyzing loads on a schematic…
Look at either the slow or regular speed winding. These are both 120 VAC loads. As with any such load, in order to run, one side of the load must get Line voltage and the other side must get Neutral.
With this in mind, the answer to your question is easy to determine by deduction: the “top” of each winding is connected to Line through the overload protector, lid switch, and timer Line switch. That’s easy to see. Knowing that and also knowing that the other side of the these windings must get Neutral in order to operate, then we know right off the bat by deduction that timer cams 6 and 8 are switching Neutral to the windings.
I know, it’s so easy it’s hard! But I use this trick all the time when I’m trying to figure out how a circuit is supposed to work.
And my compliments for taking the time to understand what’s behind this question!
