ASSEMBLY To install blade guard:  Lift the guard lever up to unlock.  With the front of the blade guard raised, lower the back of the guard into the middle hole of the riving knife. Push the front of the guard down until it is parallel to the table (see figure 24). If the blade guard is not parallel to the table, the riving knife is not in the "up" position.  Lock the guard in place by pushing the guard lever down. NOTE: Blade alignment can be adjusted for different blade widths. Refer to: To Check and Align the Riving Knife and Saw Blade. Check the blade guard assembly for clearances and free movement. TO CHECK AND ALIGN THE RIVING KNIFE AND SAW BLADE See Figure 25. If the riving knife is out of alignment with the saw blade, adjustment is needed. To check alignment of the riving knife:  Unplug the saw.  Raise the saw blade by turning the height adjusting knob 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. To adjust (horizontally and vertically):  Remove the anti-kickback pawls and blade guard assembly.  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 the screws.  Check again for squareness and continue to adjust if needed.
