Splitter/Riving Knife Installation &
Removal
The splitter/riving knife must be correctly installed,
adjusted, and aligned in order to provide the maxi-
mum safety benefit.
The splitter/riving knife attaches to the mounting
block as shown in Figure 57. Always firmly tighten
the hex nut when securing the splitter/riving knife
in place.

Figure 57. Installing splitter/riving knife on
mounting block.
Secure the splitter/riving knife so that the top of
it is 1–5mm below the top level of the blade, as
shown in Figure 58.
Minimum 1mm
Maximum 5mm
Figure 58. Height difference between splitter/
riving knife and blade.
The height difference between the splitter/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 thickness of the workpiece).
The splitter/riving knife also prevents the freshly
cut sides of the workpiece from pinching the blade
and causing kickback. For maximum effective-
ness of this safety design, the splitter/riving knife
must be positioned within 3–8mm from the blade,
as shown in Figure 59.

Once the splitter/riving knife is properly positioned
at the correct distance from the blade, verify that
it is aligned with the blade by checking the align-
ment with a straightedge in the top and bottom
locations shown in Figure 60.

Figure 60. Checking top and bottom splitter/
riving knife alignment with blade.
The splitter/riving knife should be parallel with the
blade along its length at both positions and should
be in the "Alignment Zone" shown in Figure 61.
