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 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 20 illustrates the wrong way to cut
these extrusions. Use a stick wax cutting lubricant when
cutting aluminum. Apply the stick wax cutting lubricant
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 4 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 (406mm)] work-
pieces when a special set up is used. To set the saw up for
these workpieces, follow these steps:
1. Remove both left and right sliding fences from the saw
and set aside. To remove them, unscrew the fence
knobs several turns and slide each fence outward.
Adjust and lock the miter control so that it is at 0
degrees miter.
2. Make a platform using a piece of 1.5 inch (38mm) thick
particleboard or similar flat strong 1.5 inch thick wood
to the dimensions: 14.5" x 26" (368 x 660mm). The
platform must be flat otherwise the material could
move during cutting and cause injury.
3. Mount the 14.5" x 26" platform to the saw using 4
three-inch long wood screws through the holes in the
base fence (Fig. 24). Four screws must be used to
properly secure the material. When the special set up
is used, the platform will be cut into two pieces. Ensure
the screws are tightened properly otherwise material
could loosen and cause injury. Ensure the platform is
firmly flat on the table, against the fence, and centered
evenly from left to right.
WARNING: Ensure the saw is mounted firmly to a
stable flat surface. Failure to do so could cause the saw
to be unstable and fall causing personal injury.
4. Place the workpiece to be cut on top of the platform
mounted to the table. Ensure the workpiece is firmly
against the backfence (Fig. 25).
5. Secure the material before cutting. Cut slowly through
the material using a out-down-and-back motion.
Failure to clamp securely or cut slowly could result in
the material coming loose and causing injury.
After several cuts are made at various miter angles other
than 0°, the platform may weaken and not properly support
the work. Install a new, unused platform to the saw after
presetting the desired miter angle.
