BEVEL SETTING TYPE OF CUT
RIGHT SIDE, OUTSIDE
CORNER:
1. Top of molding against fence
33.85° Left
2. Miter table set right 31.62°
3. Save right end of cut
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.
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 18. 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 avail-
able 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 90º 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 18.
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 D WALT retailer or D
E
vice 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 20 illustrates the wrong way
to cut these extrusions. Use a stick wax cutting lubricant
when cutting aluminum. Apply the stick wax cutting lubri-
cant 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 page 5 for
correct saw blade.
BOWED MATERIAL
When cutting bowed material always position it as shown
in Figure 21 and never like that shown in Figure 22.
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 23. 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.
SPECIAL SET-UP FOR WIDE CROSSCUTS
Your saw can cut very wide [up to 16 inch (406 mm)] work-
pieces when a special set up is used. To set the saw up
for these workpieces, follow these steps:
