ASSEMBLY
 Align the slot in the pawls over the rear notch in the riving
knife.
 Push the pawl handle down snapping them into place
and release the button.
NOTE: Pull on the handle to make sure pawls are
securely locked.
To install blade guard:
 With the front of the blade guard raised and the guard lever
unlocked, 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. 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 lever down.
NOTE: Blade alignment with the riving knife 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 20.
To check alignment of the riving knife:
 Unplug the saw.
 Raise the saw blade by turning the height/bevel adjusting
handwheel counterclockwise.
 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.
 From the back of the saw, loosen the adjustment 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.
