ASSEMBLY
To install blade guard:
 Lift the guard lever up to unlock.
 With the front of the blade guard raised and the guard lever
unlocked, lower the back of the guard into the middle slot
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 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 40.
To check alignment of the riving knife:
 Unplug the saw.
 Raise the blade by unlocking the height adjusting
handwheel and turning it 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):
 Remove the anti-kickback pawls and blade guard
assembly.
 Using a 4 mm hex key, 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.
To adjust (vertically):
 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.
 Once properly aligned, securely retighten all screws.
 Check again for squareness and continue to adjust if
needed.
