CUTTING BASE MOLDING (Fig. 36)
Base moldings and many other moldings
can be cut on a miter saw. The proper
setup of the saw depends on base molding
characteristics and applications, as
described below. Perform practice cuts on
scrap materials to achieve best results.
1. Always make sure moldings rest firmly
against the fence and table. Use hold-
down clamp provided, a crown molding
vise, or C-clamps and place tape on the
area being clamped to avoid marks on
the workpiece.
2. Reduce splintering by taping the cut
area prior to making the cut. Mark the cut
line directly on the tape.

3. Splintering is typically due to incorrect blade style, dull blade, thinness of
workpiece, or improperly dried wood.
4. Place the workpiece 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.
5. Align the "red laser line" to touch the right edge of the cut line marked on
the workpiece.
6. Use the hold down clamp to secure workpiece against saw table and fence.
7. When cutting long workpieces, pull out the extension rail for extra support
for the long workpieces.
NOTE: Always perform a dry run cut so you can determine if the operation being
attempted is possible before power is applied to miter saw.
COMPOUND MITER CUTTING (Fig. 37)
A compound miter cut is a cut made using a miter angle and a bevel angle at the
same time. This type of cut is used for decorative moldings, picture frames, and
other fine joinery.
To make this type of cut, the miter table must be rotated to the correct miter
angle and the saw arm must be tilted to the correct bevel angle.
Always take special care when making compound miter cuts, due to the
interaction of the two angle settings.
Adjustments of miter and bevel settings are dependent on one another. Each time the
miter setting is adjusted, the effect of the bevel setting also changes. Each time the
bevel setting is adjusted, the effect of the miter setting is changed.
It may take several settings to obtain the desired cut. The first angle setting
should be checked after setting the second angle, since adjusting the second
angle affects the first.
