The electric traction motor that runs the pump has blowers on it to keep it cool. The blowers turn on everytime the pump is turned on except when the switch is placed in the manuel mode instead of the automatic mode. Well guess what? Someone put the switch in manuel mode by mistake and the pumps electric traction motor was running without the blowers causing the traction motor to burn up. Also don't get your finger between the bull wheel and the belts. A 90K mistake and a pinched finger.
