FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and

Adjusting the shoe (Fig. 1 & 2)
When the blade loses its cutting efficiency in one place
GEB164-1
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.
