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.
Never place your hand near the rotating accessory. Accessory may kickback
over your hand.
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.
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.
