CAUTION:
Before plugging in the tool, always check to see that the
slide switch actuates properly and returns to the "OFF"
position when depressed.
To start the tool, move the slide switch forward, and the
slide switch will lock in the "ON" position. To stop, lightly
depress the rear of the slide switch, and it will return to
the "OFF" position.
Operation (Fig. 5 & 6)
Turn the tool on and set front ends of the side blades on
the workpiece. Now simply move the tool forward, keep-
ing the side blades flush with the workpiece surface.
CAUTION:
When cutting a small portion of the workpiece, you may
have difficulty completing the end of the cut. In that case,
try to cut it again, pulling the workpiece back slightly.
