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.
