Cutting Crown Molding - Performax 240-3688 Operator's Manual

3 . Splintering typically happens due to
incorrect blade style, dull blade, thinness
of work piece, or improperly dried wood .
NOTICE: Always perform a dry-run cut so
you can determine if the operation being
attempted is possible before power is
applied to miter saw.
4 . Place the work piece flat on the miter
table with one edge securely against the
fence . If the board is warped, place the
convex side against the fence . If the
concave edge of the board is against
the fence, the board could collapse
on the blade at the end of the cut and
jam the blade (Fig . 34 and 35) .
5 . Align your pencil line in the middle
of the dual laser lines .
6 . When cutting long work pieces, use
extension wing for extra support for
the long work pieces .
7 . Carefully follow all instructions for
applicable miter, bevel or compound
cuts .

CUTTING CROWN MOLDING

(FIG. 37)
WARNING:
hold-down clamp, and place tape on the
area being clamped to avoid marks on the
work piece.
Your miter saw is ideal for cutting crown
molding . To fit properly, crown molding
must be compound-mitered with extreme
accuracy . To fit flat against the ceiling and
wall, the sum of the angles of the crown
molding's two connecting surfaces must
equal 90° .
When setting the bevel and miter angles for
compound miter cuts, remember that the
settings are interdependent; changing one
also changes the other .

OPERATION
Always uses the
FIG. 37
Keep in mind that, because it is very easy for
the angles of crown molding to shift slightly,
all settings should be tested on scrap
molding . Also, most walls do not have angles
of precisely 90°; therefore, you will need to
fine-tune your settings .
When cutting crown molding, the bevel
angle should be set at 33 .9°, and the miter
angle should be set at 31 .6° either left
or right, depending upon the desired cut
for the application .
See the following table for correct angle
settings and correct positioning of the
crown molding on the miter table .
