Adjusting Riving Knife
Lateral Alignment
To help prevent kickback, ensure the blade and riving knife are
aligned. Check and adjust the alignment after each blade change.
Checking Alignment
1. Lift the blade guard and pawl.
2. Place a straightedge (A) on the table so it rests against the
blade (B) and riving knife (C). See Figure 15.
3. Rotate the blade so the top of one tooth touches the
straightedge.
Adjusting Alignment
1. Remove the table insert.
2. Loosen the lock handle (D) and remove the riving knife.
Note the direction the riving knife needs to move to align
with the blade.
3. Using a 3 mm hex wrench, adjust the four set screws (E),
which are accessible through openings located in the
corners of the floating clamp block (F). See Figure 17.
4. If necessary, repeat the above procedure.
Adjusting the Blade-to-Knife Gap
• Tools: 4 mm hex wrench
To limit kickback, the gap between the blade and riving knife
should be between 3 mm and 8 mm. If adjustment is needed,
note whether the blade-to-knife gap needs to be increased or
decreased. Then adjust as follows:
1. Remove the blade guard, pawl, table insert and riving knife.
2. Loosen two socket head flat screws (G) with a 4 mm hex
wrench. See Figure 17.
3. Reposition the fixed clamp block (H) on the extension
plate (I). Ensure the gap is between 3 mm and 8 mm. See
Figure 18.
4. Tighten the socket head screws (G).
5. Reinstall the riving knife, tighten the lock handle and
check the gap.
