Cutting trim moulding and other frames (fig. R2)
Sketch B in Figure R2 shows a joint made by setting the mitre
arm at 45º to mitre the two boards to form a 90º corner. To
make this type of joint, set the bevel adjustment to zero and
the mitre arm to 45º. Once again, position the wood with the
broad flat side on the table and the narrow edge against the
fence.
Figures R1 and R2 are for four-sided objects only.
As the number of sides changes, so do the mitre and bevel
angles. The chart below gives the proper angles for a variety
of shapes.

The chart assumes that all sides are of equal length. For a
shape that is not shown in the chart, use the following formula:
180º divided by the number of sides equals the mitre (if the
material is cut vertically) or bevel angle (if the material is cut
laying flat).
Cutting compound mitres (fig. R3)
A compound mitre is a cut made using a mitre 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 R3.
Note: If the cutting angle varies from cut to cut, check that
the bevel lock knob and the mitre lock handle are securely
locked. These must be locked after making any changes in
bevel or mitre. The chart at the end of this manual (Table 1)
will assist you in selecting the proper bevel and mitre settings
for common compound mitre cuts. To use the chart, select the
desired angle A (Fig. R3) of your project and locate that angle
on the appropriate arc in the chart. From that point follow the
chart straight down to find the correct bevel angle and straight
across to find the correct mitre angle.
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 26º exterior angles
(Angle A, Fig. R3), use the upper right arc. Find 26° on the arc
scale. Follow the horizontal intersecting line to either side to
get mitre angle setting on saw (42°). Likewise, follow the

vertical intersecting line to the top or bottom to get the bevel
angle setting on the saw (18°). Always try cuts on a few scrap
pieces of wood to verify the settings on the saw.
Cutting base moulding (fig. S)
Straight 90º 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.
Cutting base moulding up to 3.5" (90 mm) high
vertically against the Fence
Position material as shown in Figure S. All cuts should be
made with the back of the moulding against the fence and with
the bottom of the moulding against the table.

Material up to 3.5" (90 mm) can be cut as described above.
Cutting crown moulding
In order to fit properly, crown moulding must be compound
mitred with extreme accuracy.
The two flat surfaces on a given piece of crown moulding are
at angles that, when added together, equal exactly 90°. Most,
but not all, crown moulding 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 mitre saw has special preset mitre detent points at 31.6°
left and right for cutting crown moulding at the proper angle.
There is also a mark on the bevel scale at 33.8°.
The Bevel Setting/Type of Cut chart gives the proper settings
for cutting crown moulding. (The numbers for the mitre 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.
