English
WARNING:
Before performing any adjustment, make sure tool is unplugged from power supply and
switch is in off position. Failure to do so could result in serious personal injury.
WARNING:
Make sure the blade guard is reinstalled immediately after making any adjustment which
requires it to be removed. Failure to heed this instruction could result in serious personal
injury.
The table saw has been adjusted at the factory for making very accurate cuts. However, some components
might have been jarred out of alignment during shipping. Also, over a period of time, readjustment will
probably become necessary due to wear.
Carefully check alignment with a framing square before beginning adjustments to confirm whether they
are necessary. Use test cuts after completing adjustments to avoid damaging workpiece.
RIVING KNIFE AND SAW BLADE ALIGNMENT (FIG. 29a-29b)
Blade and riving knife alignment is set at factory and in most cases will not need to be adjusted. However,
the alignment should always be checked after installing blade or adjusting riving knife, and can be adjusted
if necessary. If riving knife is out of alignment with blade, adjustment is needed. Riving knife must be in
alignment front to back.
CAUTION:
Unplug saw. With bevel adjustment assembly in vertical (0 degree) position, raise blade
by turning height adjusting knob clockwise. Remove anti-kickback pawls and blade guard.

Place framing square between carbide teeth and
measure from blade. This step will ensure framing
square is square against blade from front to back
of blade.
If the riving knife is out of alignment with the saw
blade, adjustment is needed. The blade and riving
knife must always be correctly aligned so that the
cut workpiece will pass on either side of the riving
knife without binding or twisting to the side.
Improper riving knife alignment can cause
kickback and serious injury.
Make sure the blade guard and anti-kickback
pawls are reinstalled immediately after making
any adjustment which requires it to be removed.
Failure to heed this instruction could result in
serious personal injury.
