(9) Cut surface quality during miter/bevel cutting
The quality of the cut surface depends on the
type of cutting operation (miter or bevel), the
type and sharpness of saw blade, whether the
workpiece is cut to the left or right, and various
other factors. In miter and bevel cutting in
particular, cutting is performed across the wood
grain, so the condition of the cut surface
depends on whether the wood is cut with or
against the grain. This is the same as when
using electric portable planers. Customers
should be advised of these phenomena so that
they understand that in cases when the cut
surface may not be as smooth as expected or
hoped for, it is not caused by the performance
of the saw blade or the Model C 12FSA.
