Cutting Base Molding (Fig. S)
ALWAYS MAKE A DRY RUN WITHOUT POWER BEFORE MAKING ANY CUTS.
Straight 90° cuts:
Position the wood against the fence and hold it in place as shown in Figure S. Turn on the saw,
allow the blade to reach full speed and lower the arm smoothly through the cut.

Position molding as shown in Figure S.
All cuts made with the back of the molding against the fence and bottom of the molding against
the base.

Material up to 3-5/8" (91 mm) can be cut as described above. For boards [up to 5-1/2" (140 mm)]
several minor concessions must be made:
When cutting a board between 3-5/8" (91 mm) and 5-1/2" (140 mm), the roller on the tip of the
guard will hang up on the workpiece. If this occurs, simply place your right thumb on the upper
side of the guard and roll the guard up just enough to clear the workpiece, as shown in Figure L.
Once you have cleared the workpiece, you can release the guard and it will continue to open as
the cut progresses.
When mitering to the right side of a base molding 3-5/8" (91 mm) standing vertically against
the fence as in Figure S, the saw can only cut through the board up to 1" (25.4 mm) from the
end of the board. Trying to cut more than an inch will cause the saw's gear case to interfere with
the workpiece. If you want to cut base molding between 3-5/8" (91 mm) and 5-1/2" (140 mm)
vertically follow the directions on this page.

* NOTE: If the cut must be made somewhere other than 1" (25.4 mm) from the end of the molding:
cut off the molding at 90° approx. 1" (25.4 mm) longer than your final length then make the miter
cut as described above.

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°. Most, but not all, crown molding has a top rear angle (the section that fits flat
against the ceiling) of 52° and a bottom rear angle (the part that fits flat against the wall) of 38°.
Your miter saw has special pre-set miter latch points at 31.6° left for cutting crown molding at the
proper angle and bevel stop pawl at 33.9° left. There is also a mark on the bevel scale at 33.9°.
The Bevel Setting/Type of Cut chart gives the proper settings for cutting crown molding. (The
numbers for the miter and bevel settings are very precise and are not easy to accurately set on
your saw.) Since most rooms do not have angles of precisely 90°, you will have to fine tune your
settings anyway.

When setting bevel and miter angles for all compound miters, remember that:
The angles presented for crown moldings are very precise and difficult to set exactly. Since they
can easily shift slightly and very few rooms have exactly square corners, all settings should be
tested on scrap molding.

Alternative Method for Cutting Crown Molding (Fig. U)
Place the molding on the table at an angle between the sliding fence
table 34 , as shown in Figure U. Use of the crown molding fence accessory (DW7084) is highly
recommended because of its degree of accuracy and convenience. The crown molding fence
accessory is available for purchase from your local dealer.
The advantage to cutting crown molding using this method is that no bevel cut is required.
Minute changes in the miter angle can be made without affecting the bevel angle. This way,
when corners other than 90° are encountered, the saw can be quickly and easily adjusted for
