CAUTION:
Always perform a dry-run cut so you can determine if the operation being attempted
is possible before power is applied to miter saw.
•
Place the work piece flat on the miter table with one edge securely against the fence. If the board is warped, place the
convex side against the fence. If the concave edge of the board is against the fence, the board could collapse on the
blade at the end of the cut and jam the blade.
•
Align your pencil line with the laser line.
•
Use the table extension when cutting long work piece.
•
Carefully follow all instruction for applicable miter, bevel or compound cuts.

CUTTING CROWN MOULDING
The miter saw does an excellent job of cutting crown moulding. In general, miter saws do a better job of cutting crown
moulding than any other tool made.
In order to fit properly, crown moulding must be compound mitered with extreme accuracy. The two contact surfaces on a
piece of crown moulding that fit flat against the ceiling and the wall of a room are at angles that, when added together,
equal exactly 90°. Most crown moulding has a top rear angle (the section that fits flat against the ceiling) of 52° and a bottom
rear angle (the section that fits flat against the wall) of 38°.
LAYING MOULDING FLAT ON THE MITER TABLE (FIG. 33)
To use this method for accurately cutting crown moulding
for a 90° inside or outside corner, lay the moulding with its
broad back surface flat on the miter table and against the
fence.
When setting the bevel and miter angles for compound
miters, remember that the settings are interdependent;
changing one angle changes the other angle as well.
Keep in mind that the angles for crown moulding are very
precise and difficult to set. Since it is very easy for these
angles to shift, all settings should first be tested on scrap
moulding. Also most walls do not have angles of exactly 90°;
Therefore, you will need to fine tune your settings.
When cutting crown moulding by this method, the bevel
angle should be set at 33.9°. The miter angle should be set
at 31.6° either right or left, depending on the desired cut for
the application. See the chart below for correct angle
settings and correct positioning of crown moulding on miter
table.
The settings in the chart on the next page can be used for
cutting All Standard (U.S.) crown moulding with 52° and 38°
angles. The crown moulding is placed flat on the miter table
using the compound features of your miter saw.
