Saw Operations

Miter Cut

A miter cut is made at 0° bevel and any miter angle in the range from 52° left to 52° 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).

Follow these instructions for making your miter cut:

1.Loosen miter lock knob 1. Lift miter detent trigger and move the saw to the desired angle, using either the detents 2 or the miter scale 3. Tighten miter lock knob (Figure 30).

2.Properly position workpiece 4. Make sure workpiece is clamped 5 firmly against the table and the fence.

!WARNING Use clamping position that does not interfere with operation. Before switching

on, lower head assembly to make sure clamp clears guard and head assembly.

3.Activate the switch. Lower the head assembly and make your cut.

4.Wait until blade comes to a complete stop before returning head assembly to the raised position and/or removing workpiece.
