When setting bevel and miter angles for all compound miters,
remember that:
The angles presented for crown moldings are very precise and
difficult to set exactly. Since they can easily shift slightly and very few
rooms have exactly square corners, all settings should be tested on
scrap molding.

SPECIAL CUTS

NEVER MAKE ANY CUTS UNLESS THE MATERIAL IS SECURED
ON THE TABLE AND AGAINST THE FENCE.
ALUMINUM CUTTING (CARBIDE TIPPED BLADE ONLY)
Aluminum extrusions such as those used when making aluminum
screens and storm windows can easily be cut with your saw using the
proper blade designed for non-ferrous metal cutting. Position the
material so that you will be cutting the thinnest cross section, as
shown in Figure 14. Figure 15 illustrates the wrong way to cut these
extrusions. Use a wax lubricant when cutting aluminum such as
Johnson's Stick Wax No.140. Apply the stick wax directly to the saw
blade before cutting. Never apply stick wax to a moving blade.
The wax, available at most hardware stores and industrial mill supply
houses, provides proper lubrication and keeps chips from adhering to
the blade.
Be sure to properly secure work. Certain workpieces, due to their
size, shape or surface finish, may require the use of a clamp, jig or
fixture to prevent movement during the cut.
BOWED MATERIAL
When cutting bowed material always position it as shown in Figure
15
