WHEN MITERING TO THE
RIGHT
To increase the miter angle when mitering to the right, move the arm to align the appropriate
vernier mark with the closest mark on the miter scale to the right. To decrease the miter angle
when mitering to the right, move the arm to align the appropriate vernier mark with the closest
mark on the miter scale to the left.
WHEN MITERING TO THE LEFT
To increase the miter angle when mitering to the left, move the arm to align the appropriate
vernier mark with the closest mark on the miter scale to the left. To decrease the miter angle
when mitering to the left, move the arm to align the appropriate vernier mark with the closest
mark on the miter scale to the right.
CUTTING BASE MOLDING
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 15. 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 15
• 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 6-3/4" (173 mm)]
several minor concessions must be made:
When cutting a board between 3-5/8" (91 mm) and 6-3/4" (173 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
16. 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 15, 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 6-3/4" (173 mm) verti-
cally follow the directions on this page.

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 31.62 ° left and right for cutting crown
molding at the proper angle and bevel stop pawl at 33.85 ° left. There is also a mark on the bevel
scale at 33.85 °.
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.
PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!

PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!
ALTERNATIVE METHOD FOR CUTTING CROWN MOLDING
Place the molding on the table at an angle between the fence and the saw table, as shown
in Figure 18A. 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
them. Use the crown molding fence accessory to maintain the angle at which the molding will
be on the wall.
INSTRUCTIONS FOR CUTTING CROWN MOLDING ANGLED BETWEEN THE FENCE
AND BASE OF THE SAW FOR ALL CUTS:
1. Angle the molding so the bottom of the molding (part which goes against the wall when
installed) is against the fence and the top of the molding is resting on the base of the saw,
as shown in Figure 18A.
2. The angled '_flats" on the back of the molding must rest squarely on the fence and base of
the saw.

Special Cuts
NEVER MAKE ANY CUT UNLESS THE MATERIAL IS SECURED ON THE TABLE AND
AGAINST THE FENCE.
ALUMINUM CUTTING
ALWAYS USE THE APPROPRIATE SAW BLADE MADE ESPECIALLY FOR CUTTING
ALUMINUM. These are available at your local DEWALT retailer or DEWALT service center.
Certain workpieces, due to their size, shape or surface finish, may require the use of a clamp or
fixture to prevent movement during the cut. Position the material so that you will be cutting the
thinnest cross section, as shown in Figure 19. Figure 19A illustrates the wrong way to cut these
extrusions. Use a stick wax cutting lubricant when cutting aluminum. Apply the stick wax directly
to the saw blade before cutting. Never apply stick wax to a moving blade.
The wax, available at most hardware stores and industrial mill supply houses, provides proper
lubrication and keeps chips from adhering to the blade.
Be sure to properly secure workpiece.
Refer to Saw Blades under OptionalAccessories for correct saw blade.
BOWED MATERIAL
When cutting bowed material always position it as shown in Figure 20 and never like that
shown in Figure 20A. Positioning the material incorrectly will cause it to pinch the blade near
the completion of the cut.
CUTTING PLASTIC PIPE OR OTHER ROUND MATERIAL
Plastic pipe can be easily cut with your saw. It should be cut just like wood and CLAMPED OR
HELD FIRMLY TO THE FENCE TO KEEP IT FROM ROLLING. This is extremely important
when making angle cuts.
CUTTING LARGE MATERIAL
Occasionally you will encounter a piece of wood a little too large to fit beneath the blade guard.
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 16. Avoid doing this as much as
possible, but if need be, the saw will operate properly and make the bigger cut. NEVER TIE,
TAPE, OR OTHERWISE HOLD THE GUARD OPEN WHEN OPERATING THIS SAW.
MAINTENANCE
DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the plastic
guard. The polycarbonate material used in the guard is subject to attack by certain chemicals.
1. All bearings are sealed. They are lubricated for life and need no further maintenance.
2. Periodically clean all dust and wood chips from around AND UNDER the base and the
rotary table. Even though slots are provided to allow debris to pass through, some dust will
accumulate.
3. The brushes are designed to give you several years of use. To replace the brushes refer to
Brushes or return the tool to the nearest service center for repair. A list of service center
locations is packed with your tool.

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.
