Why do my new dc1414f flash red when new PA14 14.5V 1.3 Ah battery is inserted? Manual said it is hot but it has not been used. This set is new replacement as the previous one immediately smoked immediately when used. After return I was told the fan screw was loose. They fixed it and I refused taking ownership as it was send to a local non Makita dealership. I insisted on a new one. Dealer refused to refund me.
