(8) Compound (miter + bevel) cutting
Compound cutting can be accomplished by combining the miter cutting and bevel cutting operations described
in paragraphs (5) and (6) above. (For details, please refer to the Instruction Manual.) When the saw blade
section (head) is inclined 45û to the left, the table can be turned up to 45û to the right and left.
(9) Crown molding cutting
This machine can cut two types of crown molding workpieces by combining the miter and bevel cutting
operations (for USA).
Figure 16 shows two common crown molding types having angles of (θ) 38û and 45û. For the typical crown
molding fittings, see Fig. 17.

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 both the miter setting and the bevel setting
(left and right 31.6û) positions.
For miter cut setting
If the turn table has been set to either of the angles described, move the turn table adjusting side handle a
little to the right and left to stabilize the position and to properly align the miter scale and the tip of the
indicator before the operation starts.
For bevel cut setting
Move handle on miter section to the right and left and check that the position is stable and the angle scale
and the tip of the indicator are properly aligned. Then tighten the clamp lever.
