COMPOUND CUT (FIG. W)
A compound cut is the combination of a miter
and a bevel cut simultaneously.
1. Loosen the bevel lock handle (1) and position
the cutting head at the desired bevel position.
Lock the bevel lock handle.
2. Loosen the miter table lock handle (2). Press
down the positive stop locking lever (3)
and position the table at the desired angle.
Release the positive stop locking lever and
lock the miter handle.

CUTTING BOWED MATERIAL (FIG. X)
A bowed workpiece must be positioned against
the fence and secured with a clamping device as
shown before cutting. Do not position workpiece
incorrectly or try to cut the workpiece without the
support of the fence. This will cause the blade to
bind and could result in personal injury.

BEVEL CUT (FIG. V)
1. When a bevel cut is required, loosen the bevel
lock handle (1).
2. Tilt the cutting head to the desired angle as
shown on the bevel scale (2). The blade can
be positioned at any angle, from a 90° straight
cut (0° on the scale) to a 45° left bevel.
3. Tighten the bevel lock handle (1) to lock the
cutting head in position.
4. Positive stops are provided at 0° and 45°.

CUTTING BASE MOLDING (FIG. Y)
Base moldings and many other moldings can
be cut on a compound miter saw. The setup of
the saw depends on molding characteristics 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. Z, AA )
Your compound miter saw is suited for the
difficult task of cutting crown molding. To fit
properly, crown molding must be compound-
miterd 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°.
