between riving knife and blade.
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.
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-
ness of the workpiece).
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.
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.
