Grinding and sanding operation
A
B
ALWAYS hold the tool firmly with one hand on rear
handle and the other on the side handle. Turn the tool
on and then apply the wheel or disc to the workpiece.
In general, keep the edge of the wheel or disc at an
angle of about 15 degrees to the workpiece surface.
During the break-in period with a new wheel, do not work
the grinder in the B direction or it will cut into the work-
piece. Once the edge of the wheel has been rounded off by
use, the wheel may be worked in both A and B direction.
Operation with wire cup brush

CAUTION:
• Check operation of brush by running tool with no
load, insuring that no one is in front of or in line
with brush.
• Do not use brush that is damaged, or which is
out of balance. Use of damaged brush could
increase potential for injury from contact with
broken brush wires.
► 1. Wire cup brush 2. Urethane washer
Unplug tool and place it upside down allowing easy access to spin-
dle. Remove any accessories on spindle. Mount urethane washer
then thread wire cup brush onto spindle and tighten with supplied
wrench. When using brush, avoid applying too much pressure which
causes over bending of wires, leading to premature breakage.
NOTE:
• When using wire cup brush, mount urethane
washer to the spindle. It will make it easier to
