cannot be adequately guarded and are
unsafe.
b. The grinding surface of center depressed
wheels must be mounted below the plane
of the guard lip. An improperly mounted
wheel that projects through the plane of
the guard lip cannot be adequately pro-
tected.
c. The guard must be securely attached to
the power tool and positioned for maxi-
mum safety, so the least amount of wheel
is exposed towards the operator. The
guard helps to protect the operator from
broken wheel fragments, accidental contact
with wheel and sparks that could ignite
clothing.
d. Wheels must be used only for specified
applications. For example: do not grind
with the side of cut-off wheel. Abrasive
cut-off wheels are intended for peripheral
grinding, side forces applied to these
wheels may cause them to shatter.
e. Always use undamaged wheel flanges
that are of correct size and shape for your
selected wheel. Proper wheel flanges sup-
port the wheel thus reducing the possibil-
ity of wheel breakage. Flanges for cut-off
wheels may be different from grinding
wheel flanges.
f. Do not use worn down wheels from larger
power tools. A wheel intended for larger
power tool is not suitable for the higher
speed of a smaller tool and may burst.
g. When using dual purpose wheels always
use the correct guard for the application
being performed. Failure to use the correct
guard may not provide the desired level
of guarding, which could lead to serious
injury.
4. Additional safety warnings spe-
cific for cutting-off operations
a. Do not "jam" the cut-off wheel or apply
excessive pressure. Do not attempt to
make an excessive depth of cut. Over-
stressing the wheel increases the loading
and susceptibility to twisting or binding of
the wheel in the cut and the possibility of
kickback or wheel breakage.

b. Do not position your body in line with
and behind the rotating wheel. When the
wheel, at the point of operation, is moving
away from your body, the possible kickback
may propel the spinning wheel and the
power tool directly at you.
c. When the wheel is binding or when inter-
rupting a cut for any reason, switch off
the power tool and hold it motionless
until the wheel comes to a complete stop.
Never attempt to remove the cutoff wheel
from the cut while the wheel is in motion
otherwise kickback may occur. Investigate
and take corrective action to eliminate the
cause of wheel binding.
d. 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.
e. 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.
f. Use extra caution when making a "pocket
cut" into existing walls or other blind
areas. The protruding wheel may cut gas
or water pipes, electrical wiring or objects
that can cause kickback.
g. Do not attempt to do curved cutting. Over-
stressing the wheel increases the loading
and susceptibility to twisting or binding of
the wheel in the cut and the possibility of
kickback or wheel breakage, which can lead
to serious injury.
