1.3 Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged grinding accessory.
Pinching or snagging causes rapid stalling of the grinding 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 a rotary burr is snagged or pinched by the workpiece, the
edge of it that is entering into the pinch point can dig into the surface of
the material causing the rotary burr to climb out or kick out .The rotary
burr may either jump toward or away from the operator, depending on
direction of its movement at the point of pinching.
Kickback is the result of power tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper precautions
