OPERATION
NESTING CROWN MOLDING AGAINST THE
MITER FENCE
See Figures 32 - 38.
To nest pieces of crown molding less than 4-5/8 in. tall:
 Set the bevel angle at 0° and the miter angle at 45° to
either the left or the right.
 Lay the crown molding on the saw with its bottom edge
resting at a natural angle flush against the fence and its
top edge resting flush against the miter table, this is called
"nesting".
 Position the crown molding in place by using the work
clamp as a material stop.
 Tighten the knob on the work clamp until it rests lightly
against the edge of the molding. Do not overtighten as
this may move the material causing misalignment.
 Before turning on the saw, perform a dry run of the cut-
ting operation to make sure that no problems will occur
when the cut is made.
 Grasp the saw handle firmly. Squeeze the switch trigger.
Allow several seconds for the blade to reach maximum
speed.
 Slowly lower the blade into and through the crown mold-
ing.
 Release the switch trigger and allow the saw blade to stop
rotating before raising the blade out of the crown molding
and removing the crown molding from the miter table.
To nest pieces of crown molding that are 4-5/8 in. and
taller:
NOTE: This method of cut is for crown molding between
4-5/8 in. and 5-1/4 in. tall. Do not attempt to cut molding
that is larger than 5-1/4 in. tall.
 Loosen the fence screw and slide miter fences toward
the saw arm until they are flush with the miter table.
 Remove the sliding miter fences by pulling them up and
away from the miter table.
 Place the left sliding miter fence on the right side of the
tool and the right sliding miter fence on the left side with
both fences facing the rear of the tool.
 Install the miter fences by aligning the small slot in the
fences with the fixed screws on the saw and pushing
down.
NOTE: The fixed screws prevent the sliding miter fences
from sliding too close to the saw arm and possibly inter-
fering with the movement of the blade. Do not remove
fixed screws.
WARNING:
Only reverse the sliding miter fences in order to
cut nested crown molding between 4-5/8 in. and
5-1/4 in. tall. Making any other cuts with the fences
reversed could result in serious personal injury.
