Attach guide to saw with edge guide facing UP as shown (Fig. 7). 4. Remove guide pin from end of guide, push pin through hole provided in guide, then into center hole of workpiece. To make sharp corners, cut up to the corner, then back up slightly before rounding the corner. After the opening is complete, go back to each corner and cut it from the opposite direction to square it off. Do not try to plunge cut into hard materials such as steel.
