RIVING KNIFE ALIGNMENT (FIG. 14)
IMPORTANT: The riving knife must always
be in line with the saw blade. The riving
knife is thinner than the width of the kerf by
approximately three thicknesses of paper on
each side (Fig. 14). The kerf is the width of the
cut made by the teeth on the saw blade.
WARNING
battery pack from the table saw before
making any adjustments and when attaching
or removing accessories.
CHECKING RIVING KNIFE ALIGNMENT
(FIG. 15a-15b)
WARNING
periodically and make adjustments as
necessary. Improperly aligned riving knife
may result in work piece instability, loss of
control, and kickback. If the riving knife is
misaligned and cannot be adjusted, do not
attempt to operate the saw. Have a qualified
service technician perform riving knife
alignment.
Check that the blade is properly aligned
parallel with the miter-gauge groove and
adjust the blade if necessary. Check that
the rip fence is aligned with the blade
and adjust the rip fence if necessary.
a. Raise the blade to the full height (up) position
and set the bevel angle to 0°. Remove the
anti-kickback device and table insert.
b. Place the rip fence on the left side of the
table. Carefully move the rip fence against
the blade so that the rip fence is parallel to
the blade and just touches the tips of the
blade teeth. Lock the rip fence and make sure
that the front and back of the blade are still
touching the rip fence (Fig. 15a).
c. Using the rip fence as a guide, check the riving
knife alignment with the plane of the saw blade.
Since the riving knife is thinner by approximately
three thicknesses of paper on each side, than
the width of the blade's kerf (Fig. 15b) you must
make a temporary paper "spacing gauge".
Make two folds in a small piece (6" x 6") of
ordinary newspaper to make three thicknesses.
Place the paper spacing gauge between the

riving knife and the rip fence.
d. Repeat step "d" with the rip fence on the
right of the blade and check with the paper
spacing gauge.
e. If the paper spacing gauge does not fit
between the rip fence and the riving knife per
steps "d" and "e" above, the riving knife is
not correctly aligned with the blade and must
be adjusted. If the riving knife is correctly
aligned with the blade, then no adjustment is
necessary.
