Base molding can be cut vertical against fence or
flat on the table. The maximum size that can be
vertical on the fence is 6-3/4.

Crown molding cuts must be positioned properly to
fit exactly.
There are two ways to cut crown molding: flat on
table or angled to table and fence.
Crown molding's "spring angle" is the angle between
the back of the molding and the bottom flat surface
that fits against the wall.
This miter saw has special miter detents at 31.6°
and a bevel detent at 33.9°. These detents allow you
to easily position most crown moldings flat on the
table and make precise cuts for 90° corners. (These
detents are only
moldings that have a 38° "spring angle".) NOTE:
These detents cannot be used with 45° crown mold-
ing.

See also pages 29 for miter and bevel angle charts
for cutting crown moldings that have 38° and 45°
spring angles and the material is laid flat on the
miter saw base. Each chart lists the exact miter
and bevel settings required for a wide range of cor-
ner angles.
Even though these angles are standards, most
rooms do not have angles of exactly 90°, there-
fore, you will need to fine tune your settings.
The optional Bosch DAF220K MiterFinder
Digital Anglefinder/Protractor measures spring
angles and corner angles, then automatically de-
crown
termines the exact miter and bevel settings
necessary to make each crown molding cut fit
perfectly.
