9.6 Riving knife alignment

9.6.1 Lateral alignment
The saw blade and riving knife must be in line as
close as possible with each other (lateral alignment)
for the prevention of kickback. Upon initial blade
guard and riving knife installation no further
adjustment should be necessary. Alignment should
be checked and adjusted, if required, after each
blade change.
Check the alignment as follows:
1. Remove blade guard, pawl assemblies, and
table insert.
2. Place a straightedge (A, Figure 23) on the
table so it rests against blade (B) and riving
knife (C). Rotate blade so that top of blade
tooth touches straightedge.

direction riving knife needs to be moved to
align it with saw blade.
