Guard for a moving tool

Abstract

Abrading and cutting devices such as saws include waste containment systems and methods to improve removal of slurry or other contaminants from a work area during operations, and separation of slurry from a carrying medium such as air. A blade guard includes fluid channels, and may be removable from a blade guard carriage. The carriage may be used to minimize any need to readjust the blade guard position when the blade guard is returned to the carriage for further use. A vacuum bar may be included on the carriage. A vacuum pickup assembly may be used with a blade guard, and the vacuum assembly may include separate and/or different vacuum pickup configurations.

 at least one wall extending adjacent the moving tool, and having an edge portion extending adjacent a work piece to be operated on by the tool and wherein the at least one wall extends away from the edge portion; and    a second wall portion contacting the at least one wall and extending from the at least one wall in a direction toward the tool and extending from the edge portion in a direction away from the edge portion.
