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.
•
Before bevel-cutting, an adjustment of sliding
fence maybe required. Refer to the section titled
"Guide fence adjustment".
5. 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 Bevel angle
Left 0 - 45
Left and Right 0 - 45
010340
When performing compound cutting, refer to
"Press cutting", "Slide cutting", "Miter cutting" and
"Bevel cut" explanations.
6. 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. See illustrations.
Fig.35
There are crown and cove molding joints which are
made to fit "Inside" 90° corners ((1) and (2) in Fig. A)
and "Outside" 90° corners ((3) and (4) in Fig. A).

Measuring
Measure the wall length and adjust workpiece on
table to cut wall contact edge to desired length.
Always make sure that cut workpiece length
at the
back of the workpiece is the same as wall length.
Adjust cut length for angle of cut. 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).
In the case of left bevel cut

Example:
In the case of cutting 52/38° type crown
molding for position (1) in Fig. A:
•
Tilt and secure bevel angle setting to
33.9° LEFT.
•
Adjust and secure miter angle setting to
31.6° RIGHT.
•
Lay crown molding with its broad back
(hidden) surface down on the turn base
with its CEILING CONTACT EDGE
against the guide fence on the saw.
•
The finished piece to be used will
always be on the LEFT side of the
blade after the cut has been made.
7. Cutting aluminum extrusion
Fig.37
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.
WARNING:
•
Never attempt to cut thick or round aluminum
extrusions.
Thick or round aluminum extrusions
can be difficult to secure and may work loose
during the cutting operation which may result in
loss of control and serious personal injury.
8. Wood facing
Use of wood facing helps to assure splinter-free
cuts in workpieces. Attach a wood facing to the
guide fence using the holes in the guide fence.
See the figure concerning the dimensions for a
suggested wood facing.
