9. Compound cutting procedures
Compound cutting can be performed by following the instructions in 7 and 8 above. For maximum
dimensions for compound cutting, refer to "SPECIFICATIONS" table on page 9.
CAUTION:
10. Crown molding cutting procedures
Fig. 28 shows two common crown molding types having angles of (θ) 38° and 45°.
For the typical crown molding fittings, see Fig. 29.
Wall
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 and right 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 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. 29 (see Fig. 30; tilt the head to the left):
q Turn the turntable 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)
w Tilt the head to the left and set the Bevel Angle as follows:
* For 45°type crown moldings: 30° ( mark)
* For 38°type crown moldings: 33.9° ( mark)
e Position the crown molding so that the upper surface (A in Fig. 28) contacts the fence as indicated in
Fig. 31.

Always secure the workpiece with the right or left hand and cut it by sliding the
round portion of the saw backwards with the left hand.
It is very dangerous to rotate the turntable to the left during compound cutting be-
cause the saw blade may come into contact with the hand that is securing the
workpiece.
