RIDGID R4513 - Installing the Blade Guard; Aligning Riving Knife and Saw Blade

22
ASSEMBLY
To install blade guard:
 Lift the guard lever up to unlock.
 With the front of the blade guard raised, 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
(see figure 24). 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 24.
To check alignment of the riving knife:
 Unplug the saw.
 Raise the saw blade by turning the height adjusting knob
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.
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.
