Spreader or Riving
Knife Alignment
Checking Alignment
The blade guard spreader and riving knife must
be aligned with the blade when installed. If the
spreader/riving knife is not aligned with the blade,
then the workpiece will be forced sideways during
the cut, which will increase the risk of kickback.
