(7) Compound (miter + bevel) cutting
Compound (miter + bevel) cutting can be accomplished by combining the miter cutting and bevel cutting
operations described in paragraphs (5) and (6) above. (For details, refer to the Instruction Manual
"Compound cutting procedures.") When the saw blade is inclined 45û to the left, the turn table can be turned
up to 45û to the left, and up to 31û to the right because hinge (A) contacts fence (B). When the saw blade is
inclined 45û to the right, the turn table can be turned up to 31û to the left, and up to 45û to the right because
hinge (A) contacts fence (A).
(8) 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 the 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 Models
C 12LSH/C 12RSH.
In the cutting examples illustrated in Fig. 37, the cut surfaces on the sides marked
better than those on the sides marked
(9) Crown molding cutting
This machine can cut two types of crown molding workpieces by combining the miter and bevel cutting
operations.
Fig. 38 shows two common crown molding types having angles of (θ) 38û and 45û. For the typical crown
molding fittings, see Fig. 39.
The table below shows the miter angle and the bevel angle settings that are ideal for the two crown molding
types.
NOTE: For convenience, positive stops are provided for the miter setting (left and right 31.6û)
positions.
