I've had my Flex 3401 for about 4 years and it has been flawless until today. It would spin when laid flat on it's back but when I pick it up to put a pad on the paint either vertically or horizontally, it shuts off. Occasionally, I could shake it and get it to turn on, but then it would stop.
I suspect it either the trigger or electronic module that plug into teh trigger. I took the handle apart and did not see anything obvious other than some dirt and dust from over the years.
Has anyone had this issue? I don't want to just randomly start replacing parts.
Thanks
