Switch action (Fig. 4)
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,
keeping 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.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Replacement of carbon brushes (Fig. 7 & 8)
Replace carbon brushes when they are worn down to
the limit mark. Both identical carbon brushes should
be replaced at the same time.
