OPERATION
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
1
at 0° and 45°.
2
COMPOUND CUT (FIG. W)
A compound cut is the combination of a mitre 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 mitre
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 mitre 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.

CUTTING BASE MOULDING (FIG. Y)
Base mouldings and many other mouldings can be cut on
a compound mitre saw. The setup of the saw depends on
moulding characteristics and application, as shown.
Perform practice cuts on scrap material to achieve best results:
1. Always make sure mouldings 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 MOULDING (FIG. Z, AA )
Your compound mitre saw is suited for the difficult task of
cutting crown moulding. To fit properly, crown moulding must
be compound-mitred 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
mitre angles for compound
mitres, remember that the
settings are interdependent;
changing one changes the other,
as well.
