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

Cutting Crown Molding
• 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
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 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.
• See also page 32 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).
• Even though these angles are standards, most
rooms do not have angles of exactly 90°, there-fore,
you will often need to fine tune your settings.
The optional Bosch DWM40L MiterFinder
Digital Anglefinder/Protractor measures spring
angles and corner angles, then automatically deter-
mines the exact miter and bevel settings
necessary to make each crown molding cut fit
perfectly.
