Dust collection assembly for a power tool

A power tool comprising:

• a housing assembly including a housing portion and an arm supported by the housing portion for rotation about an axis, the arm having an outer surface;
• a drive unit supported by the arm, the drive unit being operable to drive a tool element to work on a work piece, the arm and the drive unit being movable between a raised, non-cutting position and a lowered, cutting position;
• and
• a collection assembly operable to collect debris generated by the tool element working on the work piece, the collection assembly including a collection chute assembly having
• a first chute member positioned on the one side of the arm, and
• a second chute member positioned on the other side of the arm and connected to the first chute member, the connected first and second chute members being secured to the arm to move with the arm between the non-cutting position and the cutting position during operation of the power tool, the connected first and second chute members defining
• a wall,
• an inlet at least partially defined by the wall,
• an outlet at least partially defined by the wall,
• a first path, between the inlet and the outlet, for debris around one side of the outer surface of the arm,
• a second path, between the inlet and the outlet, for debris around the other side of the outer surface of the arm, the first and second paths merging between the arm and the outlet, and
• an aperture in the wall through which the arm extends, wherein the wall is engaged with the outer surface of the arm about the outer periphery of the arm to inhibit debris from escaping through the aperture.
