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. 42 & 43)
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.

7. Cutting aluminum extrusion (Fig. 44 & 45)
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. (Fig. 46)
CAUTION:
• Use straight wood of even thickness as the wood
facing.
WARNING:
• Use screws to attach the wood facing to the guide
fence. The screws should be installed so that the
screw heads are below the surface of the wood
facing so that they will not interfere with the
positioning of the material being cut. Misalignment
of the material being cut can case unexpected
45° type
movement during the cutting operation which may
result in a loss of control and serious personal injury.
