So until further information is forthcoming **we might ballpark speed controls on PSW reducing power to ~50% of normal and MSW to ~60% of normal**.

>> ...there is a hidden adjustment potentiometer inside for minimum power setting. Wall dimmer switches have these as well. I was able to adjust it, but I’m waiting for my tachometer to get it where it needs to be. By the sound of the motor, I can tell it will go down enough. They really should disclose this adjustment in the instructions… Note: The hidden adjustment is soldered onto the top side of the PCB inside but you need to use a small flathead screwdriver to adjust it from the back after removing the back cover. | >> ...there is a hidden adjustment potentiometer inside for minimum power setting.
