Cutting Base Moulding; Cutting Crown Moulding - Kobalt NEXT GENERATION OF TOUGH TOOLS SM2507LW User Instructions

Check for interference between the wood fence
and the lower 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 BASE MOULDING (FIG. 43)
Base mouldings and many other mouldings can
be cut on a compound miter saw. The setup of
the saw depends on moulding characteristics
and applications, as shown. Perform practice
cuts on scrap material to achieve best results:
● Always make sure mouldings rest firmly
against the fence and table. Use hold-down
or C-clamps, whenever possible, and place
tape on the area being clamped to avoid
marks.
● Reduce splintering by taping the cut area
prior to making cut. Mark cut line directly on
the tape.
● 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 MOULDING (FIG. 44, 45)
Your compound miter saw is suited for the
difficult task of cutting crown moulding. To fit
properly, crown moulding must be compound-
mitered with extreme accuracy. The two
surfaces on a piece of crown moulding that fit
flat against the ceiling and wall are at angles
that, when added together, equal exactly 90°.
Most crown moulding 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 moulding for a
90° inside or outside corner, lay the moulding
with its broad back surface flat on the saw table.
When setting the bevel and miter angles for
compound miters, remember the settings are
interdependent; changing one changes the
other, as well.
