and locate that angle on the appropriate arc in the chart. From
that point, follow the vertical line that intersects the arc at that
point straight down to find the correct bevel angle. Then follow
the horizontal line that intersects the arc straight across to find
the correct miter angle.
NOTE: Reference points marked on the arcs are at intervals
of 5˚. The distance between each reference mark is not equal,
and the arc is not part of a circle.
Set your saw to the prescribed angles and make a few trial
cuts. Practice fitting the cut pieces together until you develop a
feel for this procedure and feel comfortable with it.
EXAMPLE: To make a 4-sided box with 55° exterior angles
(angle A, figure 29), use the upper right arc. Find 55° on the
arc scale. Follow the vertical intersecting line to the top or
bottom of the graph to get the bevel angle setting on the saw
(35.4°). Follow the horizontal intersecting line to either side to
get miter angle setting on saw (29.8°). Always try the cuts on
scrap pieces of wood to verify settings on saw.
NOTE: If the cutting angle varies from cut to cut, check that
the bevel adjustment/lock handle and the miter adjust-
ment/lock handle are securely tightened. These handles must
be tightened and locked after making any changes in bevel or
miter.
Special Cuts
CAUTION: Never make any cuts unless the material is
secured against the table and fence. 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.
ALUMINUM CUTTING
Position the material so that you will be cutting the thinnest
cross section, as shown in Figure 30. Figure 31 illustrates
the wrong way to cut these extrusions. Use a wax lubricant
when cutting aluminum such as Johnson’s Stick Wax No.
140. 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 page 6 for
correct saw blade.
BOWED MATERIAL
When cutting bowed material always position the workpiece
as shown in figure 32 and never like that shown in figure 33.
Positioning the material incorrectly will cause it to pinch the
blade near the completion of the cut.

The inset box on page 14 gives the proper settings for cutting
crown molding. (The angles 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
degrees, you will have to fine tune your settings anyway.
NOTE: Pretesting with scrap materials is extremely important.
CUTTING CROWN MOLDING ANGLED BETWEEN THE
FENCE AND TABLE (NESTED)
Use of the crown molding fence accessory (DW7084) is
highly recommended because of its accuracy and conven-
ience. 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. To use the accessory, place the
molding on the table at an angle between the fence and the
saw table, as shown in figure 28.
Instructions for Cutting Crown Molding Angled between
the Fence and Base of the Saw
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 28.
2. The angled “flats” on the back of the molding must rest
squarely on the fence and base of the saw.
TO CUT AN INSIDE CORNER JOINT:
Cut the left side:
1. set the miter at 45° right.
2. Save the right side of cut.
Right side
1. Set the miter at 45° left
2. Save the left side of the cut
TO CUT AN OUTSIDE CORNER JOINT:
Cut the left side:
1. Set the miter at 45˚ left.
2. Save the right side of the cut
Cut the right side:
1. Set the miter at 45˚ right.
2. Save the left side of the cut.
CUTTING COMPOUND MITERS
A compound miter is a cut made using a miter angle and a
bevel angle at the same time. This is the type of cut used to
make frames or boxes with slanting sides like the one shown
in figure 29.
The graph shown on page 13 will assist you in selecting the
proper bevel and miter settings for compound miter cuts like
the ones necessary to make the boxes pictured in figure 29.
To use the graph, select the desired angle “A” of your project
