Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or snagged rotating
wheel, backing pad, 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 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. Always use auxiliary handle, if provided, for
maximum control over kickback or torque reaction
during start‑up. The operator can control torque
reaction or kickback forces, if proper precautions are taken.
b ) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c ) Do not position your body in line with the rotating
wheel. Kickback will propel the tool in direction opposite
to the wheel's movement at the point of snagging.
d ) 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.
e ) Do not attach a saw chain, woodcarving blade,
segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade. Such
blades create frequent kickback and loss of control.
f ) Do not "jam" the 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.
g ) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
36
the power tool motionless until the wheel comes to
a complete stop. Never attempt to remove the 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.
h ) 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.
i ) 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.
j ) 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.
Additional Safety Warnings for Abrasive
Cutting‑Off Operations:
a ) This power tool is intended to function as a cut‑off
tool. Read all safety warnings, instructions,
illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below
may result in electric shock, fire and/or serious injury.
b ) Operations such as grinding, sanding, wire brushing,
or polishing are not recommended to be performed
with this power tool. Operations for which the power
tool was not designed may create a hazard and cause
personal injury.
c ) Do not use accessories which are not specifically
designed and recommended by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not assure
safe operation.
d ) The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories cannot be
adequately guarded or controlled.
e ) The arbour size of wheels, flanges, backing pads or
any other accessory must properly fit the spindle of
the power tool. Accessories with arbour holes that do
not match the mounting hardware of the power tool will
run out of balance, vibrate excessively and may cause loss
of control.
f ) Set the depth of cut for no more than necessary. The
less wheel exposed, the less chance of binding and
kickback. Before cutting, be sure adjust shoe assembly
is tight.
g ) Do not force the tool. Forcing a cut off tool reduces
control and cutting efficiency.
h ) Do not use this tool as a table saw.
i ) Firmly secure the workpiece.
