To check alignment of the spreader/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 spreader.
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 spreader/riving knife are aligned when
the framing square contacts both the blade and spreader/
riving knife evenly with no gaps.
If the spreader/riving knife is out of alignment with the saw
blade, adjustment is needed. The spreader/riving knife must
be in alignment front to back (horizontally) and top to bot-
tom (vertically).
To adjust (horizontally):
 Remove the anti-kickback pawls and blade guard
assembly.
 Using a 4 mm hex key, loosen the screws holding the
mounting bracket.
 Reposition the spreader/riving knife left or right as needed
to align the spreader/riving knife with the saw blade.
 Once properly aligned, securely retighten all screws.

 Using a 2.5 mm hex key, loosen the set screws and screws
holding the mounting bracket.
 Slowly turn the set screws until the riving knife is aligned
with the blade.
