1. Loosen the lever and tilt the saw blade to set the
bevel angle (Refer to the previously covered "Adjusting
the bevel angle"). Be sure to retighten the lever firmly to
secure the selected bevel angle safely.
Secure the workpiece with a vise.

contact and wait until the blade attains full speed.
5. Gently lower the handle to the fully lowered position
while applying pressure in parallel with the blade and push the
carriage toward the guide fence to cut the workpiece.
6. When the cut is completed, switch off the tool and
wait until the blade has come to a complete stop
before returning the blade to its fully elevated position.
NOTICE:
When pressing down the handle, apply
pressure in parallel with the blade. If a force is applied
perpendicularly to the turn base or if the pressure direction is
changed during a cut, the precision of the cut will be impaired.

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 45°
Right 50°
Right 55°
Right 57°
When performing compound cutting, refer to "Press cutting",
"Slide cutting", "Miter cutting" and "Bevel cut" explanations.
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.
► Fig.48: 1. 52/38° type crown molding 2. 45° type
crown molding 3. 45° type cove molding
There are crown and cove molding joints which are
made to fit "Inside" 90° corners ((a) and (b) in the figure)
and "Outside" 90° corners ((c) and (d) in the figure.)

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

workpiece 4. Wall contact edge
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).

When securing aluminum extrusions, use spacer blocks
or pieces of scrap as shown in the figure to prevent
deformation of the aluminum. Use a cutting lubricant
when cutting the aluminum extrusion to prevent build-up
of the aluminum material on the blade.
