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.
Holes are provided in the fence to attach an auxiliary fence (A) and
(B) Fig. 40. 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. 40.
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).
1. Before cutting, make certain that the cutting arm and table area are at their correct settings and firmly locked in place.
2. Before cutting, determine that the workpiece is the right size for the saw.
3. Place the workpiece on the table and hold or clamp it firmly against the fence.
4. If the size of the workpiece would cause your hand to be inside the table hazard zone (see section “TABLE
HAZARD ZONE” FIG. 26), use a clamp to secure the workpiece.
5. For best results, cut at a slow, even cutting rate.
6. Never attempt any freehand cutting (wood that is not held firmly against the fence and table).
ADJUSTING LOWER BLADE GUARD
After an extended period of use, the movable lower blade guard
(A) Fig. 39 may not operate smoothly when the cuttinghead is
lowered. You can correct this by adjusting the nut (B) until the
lower blade guard (A) moves freely
.
Do not over-tighten the nut as this can make
the guard hard to move.

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 that the blade is cutting through the smallest cross-section (Fig. 41). The wrong way to cut aluminum angles is illustrated
in Fig. 42). 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.
