   Here's the blower unit for one of those big boys.  ;D

Unplug the unit and remove the 8-10 screws holding the impeller housing dust port Inlet. There is a set screw In the middle of the impeller. Check to see if it has come loose. I believe it is an Allen key. (Metric) This malfunction is common to HF DC units. I've put locktite on mine to help avoid any dangers with the impeller coming loose. Also with the guard off. Turn the unit on to you see if the impeller is spinning. don't stick your hands anywhere near the blade when it is plugged in and on. Risk of losing fingers.  ;D.
