To cut a dado with a dado blade:
1. Adjust the dado blade to the desired depth of
cut.
2. Adjust the distance between the fence and the
inside edge of the blade, as shown in Figure
50, to dado the length of a workpiece.
—
If dadoing across the workpiece, use the
miter gauge and carefully line up the
desired cut with the dado blade. DO NOT
use the fence in combination with the miter
gauge.
3. Reconnect the saw to the power source.
4. Turn the saw ON. The blade should run
smooth, with no vibrations.
5. When the blade has reached full speed, per-
form a test cut with a scrap piece of wood.
6. If the cut is satisfactory, repeat the cut with
the actual workpiece.
Cutting Dadoes with a Dado Blade
Because dado blades are much wider than stan-
dard blades, they place a greater amount of force
against the workpiece when cutting. This addition-
al force increases the risk of kickback, requiring
the operator to take additional steps when cutting
to keep their injury risk at an acceptable level.
Dado blades have a higher risk of kickback
than normal blades because their larger size
applies stronger forces to the workpiece.
This risk increases relative to the depth and
width of the cut. To minimize your risk of
serious personal injury, ensure that stock
is flat and straight, and make multiple light
cuts (rather than one deep cut) to achieve
the desired cutting depth.
Figure 51. Example of dado being cut with
multiple light cuts, instead of one deep cut.
The
Figure below demonstrates the sequential
process of making multiple, light cuts that get
progressively deeper. The actual number of cuts
used should be determined by workpiece hard-
ness, total dado depth, and feed rate. In general, if
you hear the motor slow down during the cut, you
are cutting too deep or feeding too fast.
