Cutting Base Molding
•Base molding can be cut vertical against fence or flat on the table. The maximum size that can be vertical on the fence is
•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.

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 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.
•See also pages 29 & 30 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.
