• 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:
• 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 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
15˚
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.

• 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 ure-
thane 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.
