OPERATION
CUTTING WARPED MATERIAL
See Figures 37 - 38.
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 37.
If the warped material is positioned the wrong way as shown
in figure 38, 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.
