Saw Operations

Crown Molding Laying Flat on Table

• Notes: Position workpiece with its back flat on the

saw table.

• Always place top edge of molding against fence

(Decorative edge is at the bottom of crown mold-

ing .)

• "Spring angle" refers to angle between wall and

crown molding.

• Cutting crown molding flat on the table can be done

either as a chop cut or a slide cut depending on the

width of the workpiece.

1. For 90-0corner, set the bevel and miter angles

using Charts below. Tighten the miter lock knob

and the bevel lock lever (Figure 35).

2. Position molding on saw table. Clamp workpiece

in place using the quick clamp.

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. Follow procedures for either chop cut or slide cut

(see page 23).

4. Wait until blade comes to a complete stop before

returning head assembly to the raised position

and/or removing workpiece.

NOTE: ALWAYS TAKE A TEST CUT USING

SCRAP TO CONFIRM CORRECT ANGLES.
