A miter cut is made at 0° bevel and any miter angle in the
range from 48° left to 48° right.

•

The miter scale is cast-in on the base for easy reading.  

•

Positive detents have been provided for fast and accurate
mitering at 0°, 15°, 22.5°, and 45° left and right.

•

There is also a crown molding detent at 31.6° (see
Cutting Crown Molding for more information page 65).

•

The sliding fence must always be in its full right position,
for maximum support, when making miter cuts (see
Sliding Fence Adjustment, if necessary, page 54).

•

For precision settings, use the detent override to lock out
the detent.  To adjust for 1/4° angles, use the vernier
scale along with the detent override (see Vernier Scale for
details).
