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 work piece, 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 reactions 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 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.
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 or toothed saw blade. Such blades create frequent
kickback and loss of control.
