OPERATION
AUXILIARY WOOD FENCE (FIG. Z)
When making multiple or repetitive cuts that result in cut-off piec-
es of one inch or less, it is possible for the saw blade to catch the
cut-off piece and throw it out of the saw or into the blade guard
and housing, possibly causing damage or injury. To minimize this,
an auxiliary wood fence can be mounted to your saw. Holes are
provided in the saw fence to attach an auxiliary wood fence. This
fence is constructed of straight auxiliary wood approximately 3/4
inch thick by 2-1/2 inches high by 16-1/8 inches long. Attach the
wood fence securely and make a full depth cut to make a blade
slot. Check for interference between the wood fence and the low-
er blade guard. Adjust if necessary.
NOTE: This auxiliary fence is used only with the saw blade in the
0° bevel position (90° to the table).
The auxiliary wood fence must be removed when bevel cutting.

CUTTING A DIMENSIONAL 4X4 WITH ONE CUT (FIG. AA)
A dimensional 4x4 workpiece (3-1/2 in. x 3-1/2 in. ) may be cut
with one cut by attaching an auxiliary wood fence of 3/4 inch
thick. See "AUXILIARY WOOD FENCE".

VERTICAL MITER CUTTING (FIG. BB)
To make a miter cut in a 2x4 workpiece (1-1/2in. x 3-1/2in.) in the
vertical position a spacer such as the auxiliary wood fence de-
scribed in the "AUXILIARY WOOD FENCE" section is required.

CUTTING BASE MOLDING (FIG. CC)
Base moldings and many other moldings can be cut on a com-
pound miter saw. The setup of the saw depends on molding char-
acteristics and application, as shown. Perform practice cuts on
scrap material. To achieve best results:
1. Always make sure moldings rest firmly against fence and
table. Use hold-down or C-clamps, whenever possible, and
place tape on the area being clamped to avoid marks.
2. Reduce splintering by taping the cut area prior to making cut.
Mark cut line directly on the tape.
3. Splintering typically happens due to wrong blade application
and thinness of the material.

NOTE: Always perform a dry run cut so you can determine if the
operation being attempted is possible before power is applied to
the saw.
CUTTING CROWN MOLDING (FIG. DD, EE)
Your compound miter saw is suited for the difficult task of cut-
ting crown molding. To fit properly, crown molding must be com-
pound-mitered with extreme accuracy. The two surfaces on a
piece of crown molding that fit flat against the ceiling and wall are
at angles that, when added together equal exactly 90°.
Most crown molding has a top rear angle (the section that fits flat
against the ceiling) of 52°and a bottom rear angle (the section
that fits flat against the wall) of 38°.
In order to accurately cut crown molding for a 90° inside or out-
side corner, lay the molding with its broad back surface flat on the
saw table.
