Special Cuts

NEVER MAKE ANY CUT UNLESS THE MATERIAL IS SECURED ON THE TABLE AND
AGAINST THE FENCE.
ALUMINUM CUTTING (FIG. 19, 20)
ALWAYS USE THE APPROPRIATE SAW BLADE MADE ESPECIALLY FOR CUTTING
ALUMINUM. These are available at your local D
Certain workpieces, due to their size, shape or surface finish, may require the use of a clamp
or fixture to prevent movement during the cut. Position the material so that you will be cutting
the thinnest cross section, as shown in Figure 19. Figure 20 illustrates the wrong way to cut
these extrusions.
Use a stick wax cutting lubricant when cutting aluminum. Apply the stick wax cutting lubricant
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 workpiece.
Refer to Saw Blades under Optional Accessories for correct saw blade.
BOWED MATERIAL (FIG. 21, 22)
When cutting bowed material always position it as shown in Figure 21 and never like that
shown in Figure 22. Positioning the material incorrectly will cause it to pinch the blade near
the completion of the cut.
CUTTING PLASTIC PIPE OR OTHER ROUND MATERIAL
Plastic pipe can be easily cut with your saw. It should be cut just like wood and CLAMPED
OR HELD FIRMLY TO THE FENCE TO KEEP IT FROM ROLLING. This is extremely
important when making angle cuts.
CUTTING LARGE MATERIAL (FIG. 23)
Occasionally you will encounter a piece of wood a little too large to fit beneath the lower
guard. If this occurs, simply place your right thumb on the upper side of the guard and roll
the guard up just enough to clear the workpiece, as shown in Figure 23. Avoid doing this
as much as possible, but if need be, the saw will operate properly and make the bigger cut.
NEVER TIE, TAPE, OR OTHERWISE HOLD THE GUARD OPEN WHEN OPERATING THIS
SAW.
SPECIAL SET-UP FOR WIDE CROSSCUTS (FIG. 24, 25)
Your saw can cut very wide (up to 16.1" [409 mm]) workpieces when a special set-up is used.
To set the saw up for these workpieces, follow these steps:
1. Remove both left and right sliding fences from the saw and set aside. To remove them,
unscrew the fence adjustment knobs several turns and slide each fence outward. Adjust
and lock the miter control so that it is at 0º miter.
2. Make a platform using a piece of 1.5" (38 mm) thick particleboard or similar flat strong
1.5" thick wood to the dimensions: 14.5" x 26" (368 x 660 mm). The platform must be
flat, otherwise the material could move during cutting and cause injury.
3. Mount the 14.5" x 26" (368 x 660 mm) platform to the saw using four 3" (76.2 mm) long
wood screws through the holes in the base fence (Fig. 24). Four screws must be used
to properly secure the material. When the special set-up is used, the platform will be cut
