Cutting Warped Material - Ryobi MS180 Operator's Manual

When cutting crown molding by this method the bevel
angle should be set at 33.85°. The miter angle should
be set at 31.62° either right or left, depending on the
desired cut for the application. See the chart below for
correct angle settings and correct positioning of crown
molding on miter table.
The settings in the chart below can be used for cutting
All Standard (U.S.) crown molding with 52° and 38°
angles. The crown molding is placed flat on the miter
table using the compound features of your miter saw.

CUTTING WARPED MATERIAL

See Figures 40 and 41.
When cutting warped material, always make sure it is
positioned on the miter table with the convex side
against the fence as shown in figure 40.
OPERATION
If the warped material is positioned the wrong way as
shown in figure 41, it will pinch the blade near the
completion of the cut.
WARNING:
To avoid a kickback and to avoid serious personal
injury, never position the concave edge of bowed
or warped material against the fence.
