TYPICAL OPERATIONS AND HELPFUL HINTS

Before cutting, make certain the cutting arm and
table area are at their correct settings and firmly
locked in place.

Before cutting, determine that the workpiece is the
right size for the saw.

Place the workpiece on the table and hold or clamp
it firmly against the fence. Fig. 35 illustrates the
optional work clamp (A) being used to clamp a
workpiece to the fence and table.

WARNING: If the workpiece causes your hand to be
inside the table hazard area (see section “TABLE
HAZARD AREA”), clamp the workpiece in place
before making the cut, as shown in Fig. 35.

For best results cut at a slow, even cutting rate.

Never attempt any freehand cutting (wood that is
not held firmly against the fence and table).

AUXILIARY WOOD FENCE

When performing multiple or repetitive cut-off
operations that result in small cut-off pieces (one inch or
less), the saw blade can catch the cut-off pieces and
project them out of the machine or into the blade guard
and housing, possibly causing damage and/or injury. In
order to limit the possibility of personal injury or blade
guard damage, an auxiliary wood fence can be mounted
to your saw as follows:

Holes are provided in the fence to attach an auxiliary
fence (A) and (B) Fig. 36. This auxiliary fence is
constructed of straight wood approximately 1/4” thick
by 3/4” high by 16 inches long as shown at (B); and 1/2”
thick by 5” high by 17” long (A) Fig. 36.

NOTE: The auxiliary fence (A) is used only with the saw
blade in the 0 degree bevel position (90 degrees) 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. 37.
The wrong way to cut aluminum angles is illustrated in
Fig. 38. 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 MACHINE IS RUNNING.
