the direction opposite of the accessory’s rotation.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel
that is entering into the pinch point can dig into the
surface of the material causing the wheel to climb
out or kick out. The wheel may either jump toward or
away from the operator, depending on direction of the
wheel’s movement at the point of pinching. Abrasive
wheels may also break under these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given
below.
a) Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. The operator can control
kickback forces, if proper precautions are taken.
b) Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory
and cause loss of control or kickback.
c) Do not attach a toothed saw blade. Such blades
create frequent kickback and loss of control.
d) Always feed the bit into the material in the same
direction as the cutting edge is exiting from
the material (which is the same direction as
the chips are thrown). Feeding the tool in the
wrong direction causes the cutting edge of the bit
to climb out of the work and pull the tool in the
direction of this feed.
e) When using rotary files, cut-off wheels, high-
speed cutters or tungsten carbide cutters,
always have the work securely clamped. These
wheels will grab if they become slightly canted
in the groove, and can kickback. When a cut-
off wheel grabs, the wheel itself usually breaks.
When a rotary file, high-speed cutter or tungsten
carbide cutter grabs, it may jump from the groove
and you could lose control of the tool.
SAFETY WARNINGS SPECIFIC FOR GRINDING AND
ABRASIVE CUTTING-OFF OPERATIONS:
a) Use only wheel types that are recommended
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 intended for peripheral grinding, side forces
applied 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 excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases
the loading and susceptibility to twisting
or snagging of the wheel in the cut and the
possibility of kickback 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 kickback 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 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 workpiece
to minimize the risk of wheel pinching 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 areas. The
protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause
kickback.
SAFETY WARNINGS SPECIFIC FOR WIRE BRUSHING
OPERATIONS:
a) Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying 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
