CUTTING ALUMINUM
Aluminum extrusions such as used for making aluminum
screens and storm windows can easily be cut with your
compound miter saw. When cutting aluminum extrusions,
or other sections that can be cut with a saw blade and are
within the capacity of the machine, position the material
so the blade is cutting through the smallest cross-
section, as shown in Fig. 40. The wrong way to cut
aluminum angles is illustrated in Fig. 41. Be sure to apply
a stick wax (similar to Johnson’s stick wax #140) to the
blade before cutting any aluminum stock. This stick wax
is available at most industrial mill supply houses. The
stick wax provides proper lubrication and keeps chips
from adhering to the blade.
WARNING: NEVER APPLY LUBRICANT TO THE
BLADE WHILE THE MACHINE IS RUNNING.

CUTTING BOWED MATERIAL
When cutting flat pieces, first check to see if the material is bowed. If it is, make sure the material
is positioned on the table as shown in Fig. 42.
If the material is positioned the wrong way, as shown in Fig. 43, the workpiece will pinch the blade
near the completion of the cut.
