Crown Molding Lying Flat on Table
Use clamping position that
does not interfere with op-
eration. Before switching "ON", lower head as-
sembly to make sure clamp clears guard and
head assembly.
Be aware of the path of the
saw blade. Make a dry run
with the battery pack disconnected and the
saw switched OFF by conducting a simulated
cutting cycle, and observe the projected path
of the saw blade. Keep hands at least six (6)
inches (152mm) away from the projected path
of the saw blade.
NOTE: Position workpiece with its back flat on
the saw table (Fig. 57, 22).

Always place top edge of molding against fence
(12). (The decorative edge is at the bottom of
crown molding.)
"Spring angle" refers to angle between wall and
crown molding.
Cutting crown molding flat on the table (22) can
be done either as a chop cut or a slide cut de-
pending on the width of the workpiece.
For narrow cutoffs when cutting crown flat on
table, you will need a special auxiliary fence.
See "Making an Auxiliary Fence" on page 33.
1. For 90° corner, set the bevel and miter an-
gles, see the "Miter and Bevel Settings for
Standard Crown Molding Cuts (With Mold-
ing Flat on Table)" table. Tighten the miter
lock knob (20) and the bevel lock knob (Fig.
52, 34).
2. Position molding on saw table (Fig. 57, 22).
Clamp workpiece in place using the quick
clamp (44).
3. Follow either the procedure "Chop Cuts" on
page 37 or "Slide Cuts" on page 38.
4. Wait until saw blade comes to a complete
stop before returning head assembly (Fig.
56, 28) to the raised position and then re-
move workpiece.
NOTE: Always take a cut using scrap to confirm
correct angles.
See the "Miter and Bevel Settings for Standard
Crown Molding Cuts (With Molding Flat on Ta-
ble)" table for helpful hints on cutting crown
molding for corners that have 90° angles.
