Cutting Bowed Material - Delta ShopMaster MS450 Manual De Instrucciones

fence (A) and (B) Fig. 31. This auxiliary fence is
constructed of straight wood approximately 1/2" thick by
3" high by 16 inches long as shown at (B); and 1/2" thick
by 5" high by 17" long (A) Fig. 31.
NOTE: The auxiliary fence (A) is used only with the saw
blade in the 0° bevel position (90°) to the table. The
auxiliary fence must be removed for all bevel cuts (blade
tilted).
CUTTING ALUMINUM
Aluminum extrusions (aluminum screens and storm
windows) can easily be cut with your 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. 32.
The wrong way to cut aluminum angles is illustrated in
Fig. 33. 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.
NEVER APPLY LUBRICANT TO THE
BLADE WHILE THE BLADE IS RUNNING.

CUTTING BOWED MATERIAL

1. 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. 34.
2. If the material is positioned the wrong way, as shown
in Fig. 35, the workpiece will pinch the blade near the
completion of the cut.
WORK SUPPORT EXTENSIONS
For support when cutting long pieces, construct a work
support extension. Fig. 36 illustrates the miter saw
mounted on two standard 2 x 4's (A). Fasten the four
mounting legs (two of which are shown at (B) Fig. 36 to
the 2 x 4's, using four screws (not supplied) through the
four holes in the mounting legs. The length of the 2 x 4's
(A) can vary, depending on the workpiece.
NOTE: MAKE SURE THAT THE TOP OF THE
SUPPORT 2 X 4'S (C) ARE LEVEL WITH THE MITER
SAW TABLE.
This is critical because the distance from the top of the 2
x 4's (A) to the miter saw table varies from saw to saw. In
most cases, standard 2 x 4's (C) can used. If these are
too high, cut them to fit. If the 2 x 4's are too low, use 2
x 6's. If these are high, cut them to the correct height.
