CUTTING A SLOT IN THE ZERO CLEARANCE
THROAT PLATE
In order to use your compound miter saw, you must cut
a slot through the zero clearance throat plate to allow for
blade clearance. To cut the slot, set your saw at 0° bevel,
turn saw on and allow the blade to reach full speed, then
carefully make a straight cut as far as it will go through the
throat plate. Turn your saw off and allow the blade to come
to a complete stop before raising the saw arm.
Adjust both sliding miter fences to ensure proper clearance
prior to making a bevel cut. Set the bevel angle (right) to 48°,
turn your saw on and allow the blade to reach full speed,
then carefully make another cut through the zero clearance
throat plate. Next, set the bevel angle (left) to 48°, turn your
saw on and allow the blade to reach full speed, then carefully
make another cut through the zero clearance throat plate.
The slot in the throat plate will then be wide enough to allow
the blade to pass through it at any angle from 0° to 48°. Reset
the position of the sliding miter fences.
