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) Never place our hand near the rotating accessor . Accessory may kickback over your hand.
b) Do not position our bod in the area where power tool will move if kickback occurs. Kickback
will propel the tool in direction opposite to the wheel’s movement at the point of snagging.
c) Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the
accessor . Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and
cause loss of control or kickback.
