English 9. Compound cutting procedures Compound cutting can be performed by following the instructions in 7 and 8 above. At a bevel angle of 45° and a miter angle of 45°, a workpiece of 1-25/32" (45mm) in height and up to 8-21/32" (220mm) in width can be cut. CAUTION: Always secure the workpiece with the right hand side for compound cutting. Never rotate the turntable to the right for compound cutting, because the saw blade might then contact the clamp or vise that secures the workpiece, and cause personal injury or damage. 10. Crown molding cutting procedures Fig. 27 shows two common crown molding types having angles of (θ) 38° and 45°. For the typical crown molding fittings, see Fig. 28. A upper surface Ceiling Ceiling Wall B lower surface Wall qw er Fig. 27 Fig. 28 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 (left and right 31.6°, 35.3°) and the bevel setting positions (left 30°, 33.9°). For miter cut setting If the turntable has been set to either of the angles described, move the turntable adjusting side handle a little to the right and left to stabilize the position and to properly align the miter angle scale and the tip of the indicator before the operation starts. For bevel cut setting Move handle on bevel section to the left and check that the position is stable and that the bevel angle scale and the tip of the indicator are properly aligned. Then tighten the clamp lever. Type of Crown Molding To process crown molding at positions 1 and 4 in Fig. 28.
