''Lets see what this bad boy does.'' Started sweeping with it and had my back turned to it and all of a sudden the garage lights started flickering and the sweeper was losing power than accelerating again and turned around and not sure what was coming out exactly because the tank was clean but powder or dust was shooting out the sides and blow hole like crazy! Looked exactly like a gallon of dust shooting out the blower hole at 170 mph!!! Unplugged it and scrapped the motor.
Sounds to me like the motor was burning up with the lights flickering in the garage, that was some amperage draw!!
