Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an exhaust emission control system of a working machine for preventing DPF damage by reliably warning an operator for regeneration, and performing proper manual regeneration.SOLUTION: When the amount of PM deposits exceeds a predetermined value, an alarm for manual regeneration is displayed on a display screen 6a. When no manual regeneration is performed even if an alarm is displayed, and the time t1 elapses from the regeneration alarm display, a first alarm sound is output from a speaker 6c. When the operator recognizes the first alarm sound, and operates a regeneration switch 38, the regeneration control is started. When the operator cannot recognize the first alarm sound, and the time t2 elapses from the regeneration alarm display, the second alarm sound (stronger than the first alarm sound) is output, instead of the first alarm sound, from the speaker 6c. When the operator recognizes the second alarm sound, and operates the regeneration switch 38, the regeneration control is started.
