I was replacing mac valves last week and was wondering what affect each of them have. The rear brushes I believe have 4 and I think the front has the same. I know what the brush return is and how it works but was wondering what exactly the other ones control and how it affects the brushes. I was looking for a schematic just to have on site but couldn't find one around. Thanks
