NOTE:
∗ Positive stops are provided at the right and left of the 0° center
setting, at 15°, 22.5°, 31.6° and 45° settings.
Check that the miter scale and the tip of the indicator are properly
aligned.
∗ Operation of the saw with the miter scale and indicator out of
alignment, or with the side handle not properly tightened, will
result in poor cutting precision.
CAUTION:
Never remove the side handle; use of the tool without it would be
hazardous.
To prevent an accident or personal injury always fi rmly tighten the
miter handle.
5. Bevel cutting procedures
(1) Loosen the clamp lever and bevel the saw blade to the left.
(2) Adjust the bevel angle to the desired setting while watching the bevel
angle scale and indicator, then secure the clamp lever.

WARNING:
When the workpiece is secured on the left or right side of the blade,
the short cut-off portion will come to rest on the right or left side
of the saw blade. Always turn the power off and let the saw blade
stop completely before raising the handle from the workpiece.
If the handle is raised while the saw blade is still rotating, the
cut-off piece may become jammed against the saw blade causing
fragments to scatter about dangerously.
When stopping the bevel cutting operation halfway, start cutting
after pulling back the motor head to the initial position.
Starting from halfway, without pulling back, causes the safety cover
to be caught in the cutting groove of the workpiece and to contact
the saw blade.
6. Compound cutting procedures
Compound cutting can be performed by following the instructions in 4
and 5 above. For maximum dimensions for compound cutting, refer to
"SPECIFICATIONS" table on page 6.
CAUTION:
Always secure the workpiece with the right hand side for compound
cutting. Never rotate the table 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.

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°) positions.
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.
