• Base molding can be cut vertical against fence
or flat on the table. The maximum size that can
be vertical on the fence is 3-5/8", flat on table is
10-1/4".

• Crown molding must be 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 be-
tween 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 bevel detents 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 for use
with crown moldings that have a 38° "spring
angle".) NOTE: These detents cannot be
used with 45° crown molding.

• Follow the table for helpful hints on cutting base
molding for corners that have 90° angles.
• Cutting base molding can be done either as a
chop cut or a slide cut depending on the size of
the workpiece.

• See also pages 32 & 33 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 corner 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-
termines the exact miter and bevel settings
necessary to make each crown molding cut fit
perfectly.
