Abstract

An adjustable protecting guard apparatus for a table saw having a guard positionable over the saw blade. The adjustable protection guard apparatus has a telescoping arm extending from one end of the saw table which supports a guard superstructure. A hinged connection on an edge of the guard superstructure permits the guard superstructure and the attached guard to pivot up and away from the saw blade. A control module simultaneously deactivates the motor rotating the saw blade with the pivoting of the guard superstructure. The control module has a multi-position key switch having a by-pass position permitting pivoting of the guard without de-energizing the motor. This permits difficult cuts to be made which would not be feasible with the guard in place. An anti-kickback pawl is also provided within the guard and prevents the saw from rejecting a workpiece in a direction opposite to its feed direction.
