A quick set guard system for a radial saw having an arcuately-shaped hand guard (32) attachable to outfeed end of the stationary upper protective shield (24) covering the saw blade (22). The hand guard (32) has a pawl arm (40) to which are mounted a pair of anti-kickback pawls (36, 38). The location of the anti-kickback pawls (36, 38) relative to the hand guard (32) is selected such when the hand guard (32) is positioned a selected distance from a workpiece, the location of the anti-kickback pawls (36, 38) are automatically set.

Le protège-main (32) comprend un bras à linguets (40) sur lequel est montée une paire de linguets antirecul (36, 38). L'emplacement des linguets antirecul (36, 38) par rapport au protège-main (32) est choisi de sorte que lorsque le protège-main (32) est positionné à une distance choisie d'une pièce, l'emplacement des linguets antirecul (36, 38) est automatiquement réglé.
