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.
(lateral alignment) for
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 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:
