Ok, this is totally bizarre. I was out in the garage laying the wood to my Allroad, and after having the Flex on it's back in my arms applying polish, I flip it over, manually spread, and then go to my spread on speed 2. Nothing moves!!! I just get urrrr-urrr when pressing the trigger. The damn spindle lock is locked down. ***!!! You gotta be kidding me. I was in the homestretch and it shoots craps on me. I'm pretty sure that I didn't lock it down when I had it on it's back putting some polish on the pad. I've done this a hundred times now. Took the new BP off and took of the black plastic housing and sure enough, it's locked down. I took a flathead screwdriver to try and gently press it unlocked, but no dice. Anyone have this happen to them? I PO'ed as all hell right now. I was doing Menzerna PowerGloss followed by Menzerna 106FA, and it was really coming out nice. Guess I'll be calling Powerhouse in the morning...
