OPERATION
TO CHECK, REPLACE OR ADJUST THE RIVING
KNIFE AND BLADE GUARD ASSEMBLY
The riving knife is mounted between several shims that can
be relocated as needed to center the knife behind the blade.
It is held in place by two bolts and hex nuts at its base. The
bolts are set in slots that permit front-to-back adjustment.
WARNING:
Unplug the saw before working on it. If the saw is not
unplugged, accidental start-up can occur, resulting in
possible serious injury.
■ Remove the throat plate.
■ With blade guard up, make sure the riving knife is placed
at least 1/8 in. from the outer points of the blade. See
Figure 29. Then make sure it is centered within the width
of the blade.
See Figure 30. If either placement is wrong,
adjust with the following steps.
■ Raise the saw blade by pushing the bevel locking lever to
the left and rotating the blade adjustment handle clockwise.
■ Put the saw in angle mode by moving the bevel locking
lever to the right. Slowly turn the blade adjusting handle
until the bevel indicator is at a 30˚ angle. Lock the angle
by holding the blade adjusting handle with one hand and
returning the bevel locking lever to the left with the other.
■ With the box end of the small hex key, remove the two
nuts at the base of the riving knife. Remove the riving
knife/guard assembly.
■ Rearrange the riving knife between the shims to achieve
the correct centering.
WARNING:
Properly align riving knife. Improperly aligned riving knife
can cause blade to bind which will increase risk of
kickback.
■ Adjust the bolts front-to-back as needed to place the
riving knife approximately 1/8 in. from the blade’s outer
points. Put the nuts back on and tighten.
■ Bring the blade back to the desired angle and height.
Insert the throat plate, lower the blade, and secure the
throat plate with the throat plate screw. Tighten the screw
firmly.
