So this was weird... my DW735 planer just choked on a piece of wood, shot it out at me with a loud BANG , along with a 2" black plastic knurled knob with a small chunk out of it. Hit me in the pinky finger, and it REALLY hurt. For a couple of minutes. I'll be fine...
The weird part is, after taking apart everything I dared to, basically just the cover and dust shroud, I can see no evidence of where this knob came from, and the planer still works fine. WTF?
