Abstract: A dust collection system includes a housing defining an inlet and an outlet. A fan is situated within the housing to move air from the inlet to the outlet, and a filter is removably attached to the housing to collect dust entering the housing. To prevent dust from escaping the filter when it is removed from the housing for cleaning or disposal a cover is removably attached to the filter when it is desired to remove the filter. To insure the cover is available the next time it is necessary to remove the dust-laden filter, the cover may be attachable to the housing for storage thereon.

Abstract: A portable machine tool such as a table saw that can be moved from position to position and locked in place for operation is disclosed. The portable machine tool includes a supporting base and at least one pair of spaced wheels depending from the supporting base adjacent one end. The wheels are capable of being locked in a fixed position to prevent movement of the saw or release of the wheels to enable movement of the saw to a desired position. A movable handle for movement between a first and second position provides joint operation of the wheel locking and wheel releasing elements.
