ABSTRACT:
An electrically driven portable surface treating machine such as a sander, polisher, buffer, and the like, having an oscillatable platen driven from a motor shaft and which creates dust during use, is provided with a dust collection fan on the motor shaft in a fan housing portion of the tool housing and an exhaust outlet or port which can selectively be fitted with dust collection means, such as a filter bag. The oscillatable platen is enclosed within a shroud or skirt and the interior of the shroud or skirt is ducted to the inlet of the dust collection fan housing portion. Between the shroud and the fan, there is provided a selective shutter arrangement which may be selectively opened and closed by the machine operator to enable the machine to be operated in either a "dustless" or a "non-dustless" configuration or mode of operation.
