ASSEMBLY
TO CHECK AND ALIGN THE RIVING KNIFE AND
SAW BLADE
See Figures 20 - 21.
To check alignment of the riving knife:
 Unplug the saw.
 Raise the saw blade by turning the height/bevel adjusting
handwheel clockwise.
 Adjust the bevel angle to 0° and lock the bevel locking
lever.
 Remove the anti-kickback pawls and blade guard as-
sembly.
 To check horizontal alignment, place a framing square
or straight edge against both the body of the saw blade
and the riving knife. The framing square should contact
both the blade body and riving knife evenly with no gaps.
Check the alignment with both sides of the blade body.
NOTE: The kerf or width of each tooth is wider than the
blade body. When the riving knife is properly aligned, it
will be centered on the kerf width.
 To check vertical alignment, place a framing square beside
the riving kife. The edge of the square and the riving knife
should be parallel.
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).
