3. Safety warnings specific for
grinding and abrasive cutting-off
operations:
a. Use only wheel types that are recom-
mended for your power tool and only for
recommended applications. For example:
do not grind with the side of a cut-off
wheel. Abrasive cut-off wheels are intend-
ed for peripheral grinding, side forces ap-
plied to these wheels may cause them to
shatter.
b. For threaded abrasive cones and plugs
use only undamaged wheel mandrels with
an unrelieved shoulder flange that are of
correct size and length. Proper mandrels
will reduce the possibility of breakage.
c. Do not "jam" a cut-off wheel or apply ex-
cessive pressure. Do not attempt to make
an excessive depth of cut. Overstressing
the wheel increases the loading and sus-
ceptibility to twisting or snagging of the
wheel in the cut and the possibility of kick-
back or wheel breakage.
d. Do not position your hand in line with
and behind the rotating wheel. When the
wheel, at the point of operation, is moving
away from your hand, the possible kick-
back may propel the spinning wheel and
the power tool directly at you.
e. When wheel is pinched, snagged or when
interrupting a cut for any reason, switch
off the power tool and hold the power
tool motionless until the wheel comes
to a complete stop. Never attempt to
remove the cut-off wheel from the cut
while the wheel is in motion otherwise
kickback may occur. Investigate and take
GFCI and personal protection devices like
electrician's rubber gloves and footwear will
further enhance your personal safety.
Do not use AC only rated tools with a DC
power supply. While the tool may appear to
work, the electrical components of the AC
rated tool are likely to fail and create a hazard
to the operator.

corrective action to eliminate the cause of
wheel pinching or snagging.
f. Do not restart the cutting operation in
the workpiece. Let the wheel reach full
speed and carefully re-enter the cut. The
wheel may bind, walk up or kickback if the
power tool is restarted in the workpiece.
g. Support panels or any oversized work-
piece to minimize the risk of wheel pinch-
ing and kickback. Large workpieces tend
to sag under their own weight. Supports
must be placed under the workpiece near
the line of cut and near the edge of the
workpiece on both sides of the wheel.
h. Use extra caution when making a "pocket
cut" into existing walls or other blind ar-
eas. The protruding wheel may cut gas or
water pipes, electrical wiring or objects
that can cause kickback.
4. Safety warnings specific for
wire brushing operations:
a. Be aware that wire bristles are thrown
by the brush even during ordinary opera-
tion. Do not overstress the wires by ap-
plying excessive load to the brush. The
wire bristles can easily penetrate light
clothing and/or skin.
b. Allow brushes to run at operating speed
for at least one minute before using
them. During this time no one is to stand
in front or in line with the brush. Loose
bristles or wires will be discharged during
the run-in time.
c. Direct the discharge of the spinning wire
brush away from you. Small particles and
tiny wire fragments may be discharged at
high velocity during the use of these brush-
es and may become imbedded in your skin.
Develop a periodic maintenance schedule
for your tool. When cleaning a tool be care-
ful not to disassemble any portion of the
tool since internal wires may be misplaced
or pinched or safety guard return springs
may be improperly mounted. Certain clean-
ing agents such as gasoline, carbon tetrachlo-
ride, ammonia, etc. may damage plastic parts.
