• NEVER bang or hit grinding disc or wheel onto
work.
• Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can
cause loss of control and kickback.
• NEVER use tool with wood cutting blades and other
sawblades. Such blades when used on a grinder
frequently kick and cause loss of control leading to
personal injury.
CAUTION:
• Never switch on the tool when it is in contact with
the workpiece, it may cause an injury to operator.
• Always wear safety goggles or a face shield during
operation.
• After operation, always switch off the tool and wait
until the wheel has come to a complete stop before
putting the tool down.
Grinding and sanding operation
ALWAYS hold the tool firmly with one hand on rear han-
dle 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 direc-
tion.

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.

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, assur-
ing diameter of wheel fits inside guard. Wheel can
shatter during use and guard helps to reduce
chances of personal injury.
Unplug tool and place it upside down allowing easy
access to spindle. Remove any accessories on spindle.
Thread wire wheel brush onto spindle and tighten with
