The powermate cord is snug between small latches direectly on the base. you have to remove the Height adjuster cam and depending on the model the Overload breaker as well. Pull the cap off where the plug is, and the cord itself connects Black (LEAD) to the overload breaker and White (Nuetral) to the other neutral cords. tHe Height adjuster snaps out, pry the end near the nozzle support out with a flathead screwdriver and that the majority of it.
