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 90º corner, 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.
! 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.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.
