COMPOUND
MITER CUTTING cont. (Fig. 17)
/k WARNING:
To avoid serious personal injury, ALWAYS keep your hands
outside the "no hands zone", as marked on the saw table, which is at least 3
inches from the blade. Also, NEVER perform any cutting operation "freehand"
(i.e. without holding the workpiece against the fence); the blade could grab the
workpiece, causing it to slip and twist.
14. Make sure that there wilI be no obstructions to interfere with when making the cut.
15. Hold the saw handle and use your index finger to turn on the laser switch by
pushing it forward.
16. To turn on saw, push the safety Iock button in with your thumb while squeezing
the On/Off trigger switch located under the handle (Fig.la and 1b). Allow several
seconds for the blade to reach maximum speed.
17. Slowly lower the blade into and through the workpiece.
18. Release the safety lock and trigger switch, and turn off the laser switch. Allow the
saw blade to stop rotating BEFORE raising the blade out of the workpiece.

below. Since compound cuts are the most difficult to accurately obtain, plan carefully
and make trial cuts in scrap material prior to making your required cut.

CUTTING CROWN MOLDING (Fig. 18)
Your miter saw is ideal for cutting crown molding. In order to fit properly, crown
molding must be compound-mitered
with extreme accuracy. To fit flat against the
ceiling and walt, the sum of the angles of the crown molding's two connecting
surfaces must equal 90 ° (Fig.18).
Most crown molding has a high top rear spring angle (the section that fits flat against
the ceiling) of 52 ° and a bottom rear spring 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 fiat on the miter table and against the fence
(Fig.18).
When setting the bevel and miter angles for compound miter cuts, remember that the
settings are interdependent;
changing one changes the other, as well.
Keep in mind that since 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 99 °, therefore, you wilI need to fine tune your settings.
When cutting crown molding using this method, the bevel angle should be set at
33.9 °. 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 setting
and correct positioning of the crown molding on the miter table.
