INSTRUCTIONS FOR CUTTING CROWN
MOLDING LAYING FLAT AND USING
THE COMPOUND FEATURES
1. Molding laying with broad back surface down flat
on saw table.
2. The settings below are for All Standard (U.S.)
crown molding with 52° and 38° angles.

When setting bevel and miter angles for all com-
pound miters, remember that:
The angles presented for crown moldings are very
precise. Since they can easily shift slightly and very
few rooms have exactly square corners, all settings
should be tested on scrap molding.
PRETESTING WITH SCRAP MATERIAL IS
EXTREMELY IMPORTANT!
CUTTING TRIM MOLDING AND OTHER FRAMES
Sketch B shows a joint made by setting the miter adjustment at
45° and the bevel adjustment to the zero position. The wood is
positioned with the broad flat side on the table and the narrow
edge against the fence. Mitering the boards forms a 90 degree
corner.

The two sketches below are for four-sided objects only. As the
number of sides on a project changes, so do the miter and
bevel angles. The following chart gives the proper angles to
use when making frames in a variety of shapes.
SKETCH A
The chart assumes that all sides are of equal length. For a
shape that is not shown in the chart, use the following formula:
180 ° divided by the number of sides equals the miter or bevel
angle.

CUTTING COMPOUND MITERS
A compound miter is a
cut made using a miter angle
and a bevel angle at the
same time. This is the type of
cut used to make frames or
boxes with slanting sides like
the one shown here.
The graph shown on page 9 will assist you in selecting the prop-
er bevel and miter settings for common compound miter cuts.
To use the graph, select the desired angle "A" of your project
and locate that angle on the appropriate arc in the chart. From
that point follow the chart straight down to find the correct bevel
angle and straight across to find the correct miter angle.
NOTE: If the cutting angle varies from cut to cut, check that
the bevel adjustment/lock handles and the miter adjustment-
/lock lever are securely tightened. These levers must be tight-
ened and locked after making any changes in the bevel or
miter settings.

Bowed Material

When cutting bowed material always position it as shown on
the right above and never like that shown on the left.
Positioning the material incorrectly will cause it to pinch the
blade near the completion of the cut.

Cutting Plastic Pipe or Other Round

Cross-Sectional Material

Plastic pipe and similar material
can be easily cut with your saw. It
should be cut just like wood. CLAMP
THE MATERIAL OR HOLD FIRMLY
TO PREVENT ROLLING ESPE-
CIALLY WHEN USING BEVEL OR
MITER FEATURES.
Cutting Large
Material
Occasionally you will encounter a

beneath the blade guard. A little extra
45°
clearance can be gained by rolling the
36°
guard up out of the way with your thumb
30°
as shown. Rolling the guard in this man-
25.7°
ner may also be necessary when making
22.5°
certain compound cuts. Avoid doing this
20°
as much as possible. However, the saw
18°
will operate properly and make the deeper cut with the guard
rolled up. NEVER TIE, TAPE, OR OTHERWISE HOLD THE
GUARD OPEN WHEN OPERATING THIS SAW.
described above.

Grooving

a
Your sliding compound miter saw is equipped with a grooving
lever and thumbscrew and nut to allow for groove cutting. To
use the grooving feature, flip the grooving lever (I) toward the
front of the saw, as shown.
Loosen the nut and adjust
the thumbscrew (J) to change
the depth of the groove cut. To
lock the thumbscrew in posi-
tion,
ALWAYS MAKE DRY RUNS
WITHOUT POWER BEFORE
MAKING FINISH CUTS TO CHECK THE DEPTH OF THE
BLADE.
NOTE: Your saw is not designed for use with dado blades.

Aluminum Cutting

Never make any cut without firmly clamping material.
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.

CAUTION: Never raise the guard by hand except as
retighten the nut.
