Miter stops are provided at common angles of 0°,
15°, 22.5°, 31.6°, 45° left and right, and 60° right.
Always push down miter lock handle (B, Figure 8-1)
to secure table in position.
9.5.4 Bevel cutting
Tilt cutting head to desired angle as shown on bevel
scale. Refer to
sect. 8.5.1.
The blade can be tilted at any angle, from 90°
straight cut (0° on scale) to 45° left and right bevel.
Always push down bevel lock handle (A, Figure 9-4)
to secure cutting head in position.
Bevel positive stops are provided at 0° and 45° left
and right.
9.5.5 Compound cuts
A compound cut involves both miter and bevel
angles in the same operation.
The charts in sect. 11.0 show miter and bevel
settings for specific angles of compound cuts.
9.6 Cutting bowed material
A curved or warped workpiece must be secured
against the fence and with a clamping device used.
To help prevent binding, place convex side of
workpiece against fence. An extremely warped
piece should not be used.
9.7 Rough cutting a dado
1. Mark lines identifying width and depth of
desired cut on the workpiece and position on
the table so that inside tip of blade is positioned
on the line. Use hold down clamp to secure
workpiece.
2. Set cutting depth as described in sect. 8.6.
3. Cut two parallel grooves, then remove the
material between them.
9.8 Base molding
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.
Perform practice cuts on scrap material to achieve
best results.

Make sure that moldings rest firmly against
fence and table. Use hold-down, crown molding
vise 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 the cut. Mark the cut line directly on
the tape.

Splintering typically happens due to an incorrect
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.
9.9 Crown molding
Your compound miter saw is suited for the difficult
task of cutting crown molding. To fit properly, crown
molding must be compound-mitered 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°.
In order to accurately cut crown molding for a 90°
inside or outside corner, lay the molding with its
broad back surface flat on the saw table.
When setting the bevel and miter angles for
compound miters, remember that the settings are
interdependent – changing one changes the other.
10.0 User-maintenance
Always disconnect power to
the machine (unplug) before performing
maintenance. Failure to comply may result in
serious personal injury.
Never use gasoline or any highly volatile
solvents to clean the miter saw.
Use only replacement parts that are identical to
the parts list at the end of this manual and
reassemble exactly as the original assembly to
avoid electrical shock.
10.1 General cleaning

Wipe off machine with a dry cloth. Use a bristle
brush for hard-to-reach areas.

Vacuum or blow out motor air vents.
Wear proper eye and
respiratory protection when using
compressed air.

Periodically, saw dust will accumulate under
saw table and base. This could cause difficulty
in the movement of the table when setting up a
miter cut. Frequently blow out or vacuum up the
saw dust. Turn saw over and blow out dust from
beneath saw table.

Wipe dust/debris off the slide bars.

Clean out the fence extension trackways.

Remove table inserts to clear away any small
pieces beneath. Reinstall table inserts before
operating.
