OPERATION
NOTICE: Always use the hold-down
clamp, and place tape on the area being
clamped to avoid marks on the workpiece.
Your miter saw is ideal for cutting crown
molding. To fit properly, crown molding
must be compound-mitered with extreme
accuracy. To fit flat against the ceiling and
the wall, the sum of the angles of the crown
molding’s two connecting surfaces must
equal 90°.
When setting the bevel and miter angles for
compound miter cuts, remember that the
settings are interdependent; changing one
changes the other, as well.
Keep in mind that, because it is very easy for
the angles of crown molding to shift slightly,
all settings should be tested on scrap
molding. Also, most walls do not have
angles of precisely 90°, and therefore, you
will need to fine-tune your settings.

When cutting crown molding, the bevel
angle should be set at 33.9°, and the miter
angle should be set at 31.6° either left or
right, depending on the desired cut for the
application. See the following table for
correct angle setting and correct positioning
of the crown molding on the miter table.
