Riving Knife Adjustment
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 the blade guard and pawl (A, E,
Fig. 7).
2. Place a straightedge (A, Fig. 13) on the table
so it rests against the blade (B, Fig 13) and
riving knife (C, Fig. 13). Rotate the blade so the
top of the blade tooth touches the straightedge.
The saw blade and riving knife must be in line.
If adjustment is required:
3. Remove the table insert.
4. Loosen the lock handle (A, Fig. 14) and
remove the riving knife, making a note as to
which direction the riving knife needs to be
moved to align it with the saw blade.
5. Using a 3mm hex wrench, make adjustments
to four set screws (D, Fig. 15) accessible
through openings located in the corners of the
floating clamp block (B, Fig. 15).
6. If necessary, repeat the above procedure.
Blade proximity alignment
The gap between the saw blade and riving knife
must be between 3 and 8mm (Figure 16) to reduce
the possibility of kickback. 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.
Referring to Figure 15:
2. With a 4mm hex wrench, loosen two socket
head flat screws (E).
Note: These screws are accessible through
openings on the floating clamp block (B)
located diagonally on either side of the lock
handle (A). They secure the fixed clamp
block (C) to the riving knife extension plate (F).
Loosening these screws (E) will allow the fixed
clamp block (C) to slide back and forth on the
extension plate (F).
3. Slide the fixed clamp block (F) toward or away
from the saw blade as required.
