ABSTRACT:
A machine (10) for performing a working operation such as cutting on a workpiece. The machine (10) has a tool (19) for performing the working operation and a drive motor (13) operable to drive the tool. The drive motor (13) has an exhaust (17) through which an exhaust fluid is discharged during operation. Means (51) are provided for delivering a dust suppression fluid such as water into the vicinity of the tool (19) for suppressing dust generated thereby. A shroud (31) is disposed about the tool (19) for containing dust and the dust suppression fluid, and an extraction line (61) communicates with the shroud (71) for extracting dust and dust suppression fluid contained thereby, as well as air within the shroud. The extraction line (61) further communicates with the exhaust (17) of the drive motor (13) for receiving the exhaust fluid discharging therefrom, the exhaust fluid mixing with the air strength flowing from the shroud.
