o. Do not run the power tool while carrying it at your
side. Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory into

Using water or other liquid coolants may result in
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, sanding band, brush or any other
of the rotating accessory which in turn causes the
uncontrolled power tool to be forced in 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
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.
your body and arm to allow you to resist kickback
forces. The operator can control kickback forces, if
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
c. Do not attach a toothed saw blade. Such blades
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

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
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
b. For threaded abrasive cones and plugs use only
undamaged wheel mandrels with an unrelieved

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
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
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
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
g. Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Supports must be placed under the workpiece near the
line of cut and near the edge of the workpiece on both
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
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
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
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
d. Do not exceed 15,000 RPM when using wire
brushes.
