The blade guard, when properly installed, should be
set up, as shown in Figure 39. It should pivot freely
up and down, then return to the table in the resting
position and completely cover the blade. It should
also swing up high enough to accommodate the
workpiece.
6. Adjust the flat head screws around the perimeter of
the insert to make sure it is flush with the table (use
a straightedge as a guide).
7. Swing one side of the blade guard up and out of the
way.
8. Lift up on the right spreader pawl, and place a
straightedge against the blade and the spreader,
making sure the straightedge does not touch a blade
tooth.
When properly aligned, the spreader will be in the
"Alignment Zone," shown in Figure 40, and will be
parallel with the blade.
— If the spreader is not inside the alignment zone
and not parallel with the blade, then it needs
to be adjusted. Perform the Spreader or Riving
Knife Alignment procedure on Page 63.
Anti-Kickback Pawls
The anti-kickback pawls allow the workpiece to travel in
only one direction. If the workpiece moves backwards,
such as during a kickback, the pawls will dig into the
workpiece to slow or stop it.
To work properly, the pawls must return to their resting
position after pivoting up, as shown in Figure 41, and
they must not be engaged in the arresting hooks.
If the pawls fail to return to the resting position, the pivot
area may need to be cleaned or the spring may have been
dislodged or broken and will need to be fixed/replaced.
