Instructions for Cutting Crown Molding Angled Between the
Fence and Base of the Saw for All Cuts
1. Angle the molding so the bottom of the molding (part which goes against the wall when
installed) is against the fence and the top of the molding is resting on the base of the saw, as
shown in FigureT.
2. The angled “flats” on the back of the molding must rest squarely on the fence and base of
thesaw.

Special Cuts
NEVER MAKE ANY CUT UNLESS THE MATERIAL IS SECURED ON THE TABLE AND AGAINST
THEFENCE.
Aluminum Cutting (Fig. A, U, V)
ALWAYS USE THE APPROPRIATE SAW BLADE MADE ESPECIALLY FOR CUTTING ALUMINUM. These
are available at your local
DeWALT
retailer or
DeWALT
service center. 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U. FigureV illustrates the wrong way to cut these extrusions.
Use a stick wax cutting lubricant when cutting aluminum. Apply the stick wax directly to the saw
blade
39
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 Accessories for correct sawblade.
Bowed Material (Fig. W, X)
When cutting bowed material always position it as shown in FigureW and never like that
shown in Figure X. 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. Y)
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 Y. 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.

MAINTENANCE

WARNING: To reduce the risk of serious personal injury, turn unit off and disconnect
it from power source before making any adjustments or removing/installing
attachments or accessories. An accidental start-up can causeinjury.

WARNING: To reduce the risk of serious personal injury, DO NOT touch the sharp
points on the blade with fingers or hands while performing anymaintenance.
DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the plastic
guard. The polycarbonate material used in the guard is subject to attack by certainchemicals.
1. All bearings are sealed. They are lubricated for life and need no furthermaintenance.
