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
workpiece. 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 (optional
accessory)
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.

Unplug tool and place it upside down allowing easy
access to spindle. 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
remove wire cup brush.
Operation with wire wheel brush (optional
accessory)
CAUTION:
•
Check operation of wire wheel brush by running
tool with no load, insuring that no one is in front of
or in line with the wire wheel brush.
•
Do not use wire wheel brush that is damaged, or
which is out of balance. Use of damaged wire
wheel brush could increase potential for injury from
contact with broken wires.
•
ALWAYS use guard with wire wheel brushes,
assuring diameter of wheel fits inside guard. Wheel
can shatter during use and guard helps to reduce
chances of personal injury.
