2) KICKBACK AND RELATED WARNINGS
• Kickback is a sudden reaction to a pinched or snagged
rotating wheel, sanding band, brush or any other
accessory. Pinching or snagging causes rapid stalling of
the rotating accessory which in turn causes the
uncontrolled power tool to be forced in the direction
opposite of the accessory's rotation at the point of the
binding.
• 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 the 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 thin 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 steel saws, 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-of wheel grabs, the wheel itself usually
breaks. When the steel saw, high-speed cutters or
tungsten carbide cutter grab, it may jump from the groove
and you could lose control of the tool.
3) 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-of wheel. Abrasive cut-of 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" the 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 binding 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 the wheel is binding 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
binding.
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.
4) 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 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 brushes and may become imbedded in your skin.
