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.
