1 inch from the end of the board. Trying to cut more than
an inch will cause the saw’s gear case to interfere with
the workpiece. If you want to cut base molding between
3-1/2" and 4-1/4" wide vertically follow the directions
below.
CUTTING 3-1/2"– 4-1/4" BASE MOLDING VERTICALLY
AGAINST THE FENCE
Position molding as shown in Figure 21.
All cuts made with the back of the molding against the fence
INSIDE CORNER:
Left side
1. Position molding with bottom of molding against
the base of the saw
2. Miter left 45°
3. Save left side of cut
Right side
1. Position molding with top of the molding resting on
the base of the saw
2. Miter left 45°
3. Save left side of cut
OUTSIDE CORNER:
Left side
1. Position molding with bottom of molding against
the base of the saw
2. Miter right 45°
3. Save left side of cut
Note: If the cut must be made somewhere other than
1" from the end of the molding: cut off the molding at
90° approx. 1" longer than your final length then make
the miter cut as described above.
Right side
1. Position molding with bottom of the molding
against the base of the saw
2. Miter left 45°
3. Save the right side of cut
A third method of making the cut necessary is to make a
zero degree miter, 45 degree bevel cut. Your saw can cut
a bevel 6.1" wide.
CUTTING BASE MOLDING LAYING FLAT AND USING
THE BEVEL FEATURE
All cuts made with the saw set at 45° bevel and 0 miter
All cuts made with back of molding laying flat on the
saw as shown in figures 22 and 23.
Move the left side fence out of the path of the blade
before attempting any of the following cuts.

CUTTING CROWN MOLDING
Your miter saw is better suited to the task of cutting crown
molding than any tool made. 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
degrees. Most, but not all, crown molding has a top rear
angle (the section that fits flat against the ceiling) of 52
degrees and a bottom rear angle (the part that fits flat
against the wall) of 38 degrees.
Your miter saw has special pre-set miter latch points at
31.62 degrees left and right for cutting crown molding at
the proper angle. There is also a mark on the Bevel scale
at 33.85 degrees.
The chart below 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
degrees, you will have to fine tune your settings anyway.
PRETESTING WITH SCRAP MATERIAL IS EXTREME-
LY IMPORTANT!
