Abstract
A cooling system for a wheeled saw for widening cracks in an asphalt or concrete surface is disclosed. The cooling system includes a compressor and a water reservoir which provide pressurized air and water to one or more mist forming nozzles or fluid directing blocks. The mist is directed unto the cutting blade to keep it cool. After enlarging a crack, foreign materials are blown from the crack allowing it to be immediately sealed.
