When can the riving knife and top guard be removed on a table saw?
The top guard and riving knife can only be removed when performing rebating, grooving or trenching. These tasks generally afford the operator with some protection from the workpiece whilst the task is being performed. Operator must refer to the manufacturers instructions for the use and adjustment. Model instructions for the safe operation of specific woodworking machines are available in AS 1473.2 – 2001.
