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 31.6°,35.3°) positions.

For miter cut setting

If the table has been set to either of the angles described, move the table adjusting miter 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 right and 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.

(1) Setting to cut crown moldings at positions q and r in Fig. 21 (see Fig. 22):

qTurn the table to the right and set the Miter Angle as follows:

* For 45°	type crown moldings:	35.3° (	mark)
* For 38°	type crown moldings:	31.6° (	mark)

wTilt the head to the left and set the Bevel Angle as follows:

*For 45° type crown moldings: 30°

*For 38° type crown moldings: 33.9° ( mark)

ePosition the crown molding so that the upper surface (A in Fig. 20) contacts the fence as indicated in Fig. 24.
