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 accessoryʼs 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 wheelʼs movement at the point
of pinching. Abrasive wheels may also break under these
conditions. Kickback is the result of tool misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below:

 Push the guard down until the guard lugs engage and
rotate freely in the groove on the gear case hub.
 With the guard latch open, rotate the guard into the
desired working position. The guard body should be
positioned between the spindle and the operator to
provide maximum operator protection.
53A>1 Close the guard latch  to secure the guard
on the gear case. You should not be able to rotate the
guard by hand when the latch is closed. Do not operate
the grinder with a loose guard or the guard latch in
open position.
 To remove the guard, open the guard latch, rotate the
guard so that the lugs and slots are aligned and pull up
on the guard.
