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 miter (if the
material is cut vertically) or bevel angle (if the material is cut
laying flat).
Cutting compound miters (Fig. N2)
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 N2.
Note: If the cutting angle varies from cut to cut, check that
the bevel lock knob and the miter lock handle are securely
locked. These must be locked after making any changes in
bevel or miter.
Cutting base molding (Fig. N3)
Straight 90º cuts:
Position the wood against the fence and hold it in place as
shown in Figure N3. Turn on the saw, allow the blade to reach
full speed and lower the arm smoothly through the cut.
Position material as shown in Figure N3. All cuts should be
made with the back of the molding against the fence and with
the bottom of the molding against the table.

Cutting crown molding
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 sec-
tion that fits flat against the ceiling) of 52° and a bottom rear
angle (the part that fits flat against the wall) of 38°.

(Original instructions)
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.
Instructions for cutting crown molding laying flat
and using the compound features
Lay the molding with broad back surface down flat on saw
u
table (fig. O).
The settings below are for all Standard crown molding with
u
52° and 38° angles.
Bevel Setting Type Of Cut
LEFT SIDE, INSIDE CORNER:
1. Top of molding against fence
33.9°
2. Miter table set right 31.6°
3. Save left end of cut
RIGHT SIDE, INSIDE CORNER:
1. Bottom of molding against fence
33.9°
2. Miter table set left 31.6°
3. Save left end of cut
LEFT SIDE, OUTSIDE CORNER:
1. Bottom of molding against fence
33.9°
2. Miter table set left 31.6°
3. Save right end of cut
RIGHT SIDE, OUTSIDE CORNER:
1. Top of molding against fence
33.9°
2. Miter table set right 31.6°
3. Save right end of cut
Note: 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.
Alternative method for cutting crown molding
Place the molding at an angle between the fence (11) and the
saw table (10), with the top side of the molding on the table
and the bottom side of the molding on the fence as shown
in figure O1.
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 affect-
ing the bevel angle. This way,when corners other than 90º are
encountered, the saw can be quickly and easily adjustedfor
them.
