When the blade loses its cutting efficiency in one place
along its cutting edge, reposition the shoe to utilize a
sharp, unused portion of its cutting edge. This will help
to lengthen the life of the blade. To reposition the shoe,
push the shoe button in the "A" direction with a click and
reposition as shown in the figure which allows you to
make five-way adjustment. To secure the shoe, push
the shoe button in the "B" direction with a click.

workpiece during operation. If the shoe is removed
or held away from the workpiece during operation,
strong vibration and/or twisting will be produced,
causing the blade to snap dangerously.
