Assembly TO Check and Align the riving knife and Saw Blade See Figure 18. To check alignment of the riving knife:  Unplug the saw.  Raise the saw blade by turning the height/bevel adjusting handwheel clockwise.  Remove the anti-kickback pawls and blade guard assembly. Place a framing square or straight edge against both the saw blade and the riving knife. Note: Place framing square between carbide teeth and measure from blade. This step will insure framing square is square against blade from the front to back of blade.  The saw blade and riving knife are aligned when the framing square contacts both the blade and riving knife evenly with no gaps. If the riving knife is out of alignment with the saw blade, adjustment is needed. The riving knife must be in alignment front to back (horizontally) and top to bottom (vertically). To adjust (horizontally and vertically):  Remove the anti-kickback pawls and blade guard assembly.  Grasp the outfeed support with both hands and pull it until it is fully extended.  From the back of the saw, loosen the screws holding the mounting bracket.  Reposition the riving knife left or right as needed to align the riving knife with the saw blade.  Once properly aligned, securely retighten all screws.  Check again for squareness and continue to adjust if needed. screws correct incorrect outfeed support Fig. 17 VERTICAL ADJUSTMENT HORIZonTAL ADJUSTMENT Fig. 18 20
