NOTE: Always perform a dry run cut so you can
determine if the operation being attempted is possible
before power is applied to the saw.
CUTTING CROWN MOLDING (FIG. EE, FF)
Your compound miter saw is suited for the difficult task
of cutting crown molding. To fit properly, crown molding
must be compound-mitered with extreme accuracy. The
two surfaces on a piece of crown molding that fit flat
against the ceiling and wall are at angles that, when
added together, equal exactly 90 °.
Most crown molding has a top rear angle (the section
that fits flat against the ceiling) of 52°and a bottom rear
angle (the section that fits flat against the wall) of 38 ° .
In order to accurately cut crown molding for a 90 ° inside
or outside corner, lay the molding with its broad back
surface flat on the saw table.
When setting the bevel and miter angles for compound
miters, remember that the settings are interdependent;
changing one changes the other, as well. Also keep in
mind that the angles from crown molding are very easy
for these angles to shift slightly, all settings should be
tested on scrap molding.
Use a safety clamping vise, whenever possible, and
place tape on the area being clamped to avoid marks.
