PURPOSE:To eliminate a flux sticking to a printed circuit board holding claw by a dry work, by providing a nozzle for blowing a hot air against the printed circuit board holding claw to which a printed circuit board is not installed. CONSTITUTION:A hot air blowing nozzle 12 is provided so as to be opposed to a printed circuit board holding claw 4. To a part of the printed circuit board holding claw 4 after a printed circuit board 1 has been removed, a hot air which has been heated by a sheath heater 11 is blown from the hot air blowing nozzle 12. By this hot air, a flux which has adhered to the printed circuit board holding claw volatilizes, is converted to a rosin gas and removed. In this way, the line is cleaned.
