Saw Operations

Miter Cuts

What’s a Miter Cut – Saw features

A “miter cut” is a cross-cut made with the blade perpendicular to the horizontal table. The blade is not tilted and the bevel pointers are both on the 0° lines.

Miter cuts can be made at any angle across a workpiece within this saw’s range, from 52° left to 60° right.

The miter scale shows the angle of the blade relative to the saw’s fence. The miter pointer is attached to the turntable and indicates the saw’s miter position before the cut is made.

Ten positive detents are provided for fast and accurate preset miter angles – locations are at 45°, 31.6°, 22.5°, 15° left and right, and center at 0°. The right side has an additional detent of 60°.

The crown molding detents on the left and right are at 31.6° for compound cutting 38° “spring angle” crown molding lying flat on the table (see Cutting Crown Molding on page 45).

For precision settings at miter angles very close to the miter detents, use the miter detent override to prevent the detent from automatically engaging the detent slot. See detent override instructions on page 33.

A miter cut can be made either as a chop cut or slide cut, depending on the width of the workpiece.

The kerf inserts should be adjusted to be as close to the blade as possible to reduce splintering (see kerf insert instructions on page 20).

Reading the Miter Scale

The miter scale used on this saw includes several scales of information to help the user accurately preset this saw before making the cuts (see Figure 44).
