8.7 Riving Knife Alignment

8.7.1 Lateral Alignment
Saw blade and riving knife must be as closely
aligned as possible
prevention of kickback. This should be checked
upon initial blade guard and riving knife installation.
Alignment should also be reaffirmed after each
blade change.
Inspect alignment as follows:
1. Remove blade guard and pawl assembly.
2. Place a straightedge on table so it rests against
blade and riving knife. See Figure 8-7. Rotate
blade so that top of blade tooth touches
straightedge.
Figure 8-7
The saw blade and riving knife must be in line. If
adjustment is needed:
3. Pull up lever (A, Figure 8-8) and remove riving
knife, making note as to which direction riving
knife needs to be moved to align it with saw
blade.
4. Use 3mm hex key to make adjustments to four
set screws (B, Figure 8-8). Adjust any of the set
(lateral alignment) for
screws required to bring riving knife in
alignment with saw blade.
5. Reinsert riving knife, secure by tightening lever
(A) and check alignment per step 2.
6. Repeat steps 3–5 until alignment is correct.
8.7.2 Blade Proximity Alignment
The gap between saw blade and riving knife must
be between 3mm (0.12in.) and 8mm (0.32in.). See
Figure 8-9.
If adjustment is needed, note whether blade-to-knife
gap needs to be increased or decreased. Then
adjust as follows:
7. Remove blade guard, pawl assembly, table
insert and riving knife.
8. Use 3mm hex key to loosen two socket head
button screws (C, Figure 8-8). This will allow the
clamp plate (D) to slide back and forth on the
fixed base.
Slide clamp plate (D) toward or away from saw
blade as required. Attempt to make the gaps as
even as possible.
9. Tighten screws (C).
10. Reinsert riving knife; engage lever (A) and
check that saw blade/knife gap is between
3-8mm (Figure 8-9).
