Basic Saw Operations

Miter Cut

A miter cut is a cross-cut made at 0° bevel and any miter angle in the range from 52° left and right.

The miter scale shows the angle of the blade relative to the fence angle.

Positive detents have been provided for fast and accurate mitering at 0°, 15°, 22.5°, 31.6° and 45° left and right.

The crown molding detents (left and right) are at 31.6° (See Cutting Crown Molding for more infor- mation page 28).

For precision settings at angles next to the detents, use the detent override to lock out the detent. This prevents the wedge on the detent lever from slipping back into the detent.

The kerf inserts should be as close to the blade as possible without touching the blade (see Kerf In- serts for adjustment procedures).

follow these instructions for making your miter cut:

1.Loosen miter lock knob. Lift miter detent lever and move the saw to the desired angle, using either the detents or the miter scale. Tighten miter lock knob (Figure 35).

2.Extend the base extensions and fence on the side on which the cut will be made. (See Sliding Fence and Base Extension on page 20 & 21).

3.Properly position workpiece. Make sure work- piece is clamped firmly against the table or the fence.

! WARNING

Use clamping position that does

 

not interfere with operation. Be-

 

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

4.Follow procedures for chop cut (see page 23).

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

Bevel Cut

A “bevel cut” is a cross-cut made with the blade per- pendicular to the fence and with the table set at 0° miter. The blade can be tilted at any angle within the saw’s range: 47° left and -2° right from the vertical.

The bevel scale is sized and positioned for easy reading. And the side bevel lock lever is to lock and unlock the various settings.

A rotating Left Bevel Stop indicator allows you to set the most common bevel stops – 0°, 33.9°, 45° and 47° Left. The 33.9° bevel stop is for cutting 38° “spring angle” crown molding flat on the table. (See Compound Cuts for more information.) (See Figure 36)
