while cutting may cause unexpected kickback resulting
in possible in serious personal injury.
3. Miter cutting
Refer to the previously covered "Adjusting the miter
angle".
4. Bevel cut (Fig. 39)
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. Make sure the carriage is pulled
all the way back toward the operator. Switch on the
tool without the blade making any contact and wait
until the blade attains full speed. Then 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. 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.
WARNING:
• After setting the blade for a bevel cut, before
operating the tool ensure that the carriage and
blade will have free travel throughout the entire
range of the intended cut. Interruption of the carriage
or blade travel during the cutting operation may result
in kickback and serious personal injury.
• While making a bevel cut keep hands out of the
path of the blade. The angle of the blade may confuse
the operator as to the actual blade path while cutting
and contact with the blade will result in serious
personal injury.
• The blade should not be raised until it has come to
a complete stop. During a bevel cut the piece cut off
may come to rest against the blade. If the blade is
raised while it is rotating the cut-off piece maybe
ejected by the blade causing the material to fragment
which may result in serious personal injury.
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 the upper fence
and lower 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
Left and Right 0° - 45°
When performing compound cutting, refer to "Press
cutting", "Slide cutting", "Miter cutting" and "Bevel cut"
explanations.

6. Cutting crown and cove moldings
In the case of left bevel cut
7. Cutting aluminum extrusion (Fig. 43 & 44)
Bevel angle
Left 0° - 45°
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. 40)
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).
(Fig. 41 & 42)
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).

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.
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.
