Compound cutting
Compound cutting is the process in which a bevel
angle is made at the same time in which a miter angle
is being cut on a workpiece. Compound cutting can be
performed at the angle shown in the table.
Miter angle
Left and Right 0° - 45°
When performing compound cutting, refer to the section
for press cutting, slide (push) cutting, miter cutting and
bevel cut.
Cutting crown and cove moldings
Crown and cove moldings can be cut on a compound
miter saw with the moldings laid flat on the turn base.
There are two common types of crown moldings and
one type of cove moldings; 52/38° wall angle crown
molding, 45° wall angle crown molding and 45° wall
angle cove molding.

Measuring
Measure the wall width, and adjust the width of the
workpiece according to it. Always make sure that width
of the workpiece's wall contact edge is the same as wall
length.

Always use several pieces for test cuts to check the
saw angles.
When cutting crown and cove moldings, set the bevel
angle and miter angle as indicated in the table (A) and
position the moldings on the top surface of the saw
base as indicated in the table (B).
