Cutting Base Molding; Cutting Crown Molding - DeWalt DW707 Instruction Manual

CUTTING BASE MOLDING

ALWAYS MAKE A DRY RUN WITHOUT POWER BEFORE
MAKING ANY CUTS.
Straight 90 degree cuts:
Position the wood against the fence and hold it in place
as shown in Figure 15. Turn on the saw, allow the blade
to reach full speed and lower the arm smoothly through
the cut.
CUTTING BASE MOLDING UP TO 6" HIGH VERTICALLY
AGAINST THE FENCE
Position material as shown in Figure 15.
All cuts made with the back of the molding against the fence
and bottom of the molding against the base.

CUTTING CROWN MOLDING

Your miter saw is better suited to the task of cutting crown
molding than any tool made. In order to fit properly, crown

molding must be compound mitered with extreme accuracy.
The two flat surfaces on a given piece of crown molding are
at angles that, when added together, equal exactly 90
degrees. Most, but not all, crown molding has a top rear
angle (the section that fits flat against the ceiling) of 52
degrees and a bottom rear angle (the part that fits flat
against the wall) of 38 degrees.
Your miter saw has special pre-set miter latch points at
31.62 degrees left and right for cutting crown molding at the
proper angle and bevel stop pawls at 33.85˚ left and right.
There is also a mark on the Bevel scale at 33.85 degrees.
The chart on page 11 gives the proper settings for cutting
crown molding. (The numbers for the miter and bevel set-
tings are very precise and are not easy to accurately set on
your saw.) Since most rooms do not have angles of pre-
cisely 90 degrees, you will have to fine tune your settings
anyway.
