Riving Knife Installation & Removal
The riving knife must be correctly installed and
adjusted in order to provide the maximum safety
benefit.
The riving knife attaches to the mounting block as
shown in Figure 75. Always firmly tighten the hex
bolt when securing the riving knife in place.

Secure the riving knife so that the top of it is
1–5mm below the top level of the blade, as shown
in Figure 76.
Figure 76. Height difference between riving knife
The height difference between the riving knife and
the blade allows the workpiece to pass over the
blade during non-through cuts (those in which the
blade does not cut all the way through the thick-
Mounting
ness of the workpiece).
Block
The riving knife also prevents the freshly cut sides
of the workpiece from pinching the blade and
causing kickback. For maximum effectiveness of
this safety design, the riving knife must be posi-
tioned within 3–8mm of the blade, as shown in
Figure 77.
