When securing aluminum extrusions, use spacer blocks
deformation of the aluminum. Use a cutting lubricant
when cutting the aluminum extrusion to prevent build-up
of the aluminum material on the circular saw blade.
WARNING: Never attempt to cut thick or
round aluminum extrusions. Thick or round alumi-
may loosen during the cutting operation which may
Groove cutting
WARNING: Do not attempt to perform this
type of cut by using a wider type blade or dado
blade. Attempting to make a groove cut with a wider
blade or dado blade could lead to unexpected cutting
results and kickback which may result in serious
WARNING: Be sure to return the stopper arm
to the original position when performing other
than groove cutting. Attempting to make cuts with
the stopper arm in the incorrect position could lead to
unexpected cutting results and kickback which may
For a dado type cut, perform as follows:
1.
limit the cutting depth of the circular saw blade. Refer to
the section for stopper arm.
2. -
lar saw blade, cut parallel grooves across the width of
the workpiece using a slide (push) cut.

3. Remove the workpiece material between the
grooves with a chisel.
