Kickback and corresponding
precautions
Kickback is the sudden reaction from a
chopping or blocked grinder attachment
such as a grinding disc, grinding plate,
wire brush etc. Chopping or blocking leads
to sudden stopping of the rotating attach-
ment. This causes an uncontrolled electric
tool to accelerate in a direction counter to
the rotational direction of the attachment
tool. If, for example, a grinding disc cuts
into the workpiece or blocks it, the edge of
the grinding disc that digs into the work-
piece can get caught and, through that,
break off the grinding disc or cause a kick-
back. The grinding disc then moves towards
or away from the operator, depending on
the direction of rotation of the disc at the
blocked spot. Here, the grinding discs can
also break. A kickback is caused by wrong-
ly or incorrectly operating the electric tool.
It can be avoided by suitable cautionary
measures, such as described below.
a) Hold the electric tool very irmly and
bring your body and your arm into a
position in which you can resist the kick-
back force. Always use the supplemental
handle if available to give you the best
control over kickback force or reaction
time during acceleration. The operator
can master the kickback and reaction
force through suitable precautions.
b) Never bring your hands near a rotating
attachment tool. The attachment tool
can run over your hand in the kickback.
c) Keep your body away from the area in
which the electric tool would move dur-
ing a kickback. The kickback drives the
electric tool in the counter-direction to
the rotation of the grinding disc at the
blocked spot.
d) Work particularly cautiously in corner
areas or where there are sharp cor-
ners etc. Prevent the attachment tools
from recoiling from the workpiece and
jamming. The rotating attachment tool
tends to jam when near corners, sharp
edges or when it recoils from such. This
causes a loss of control or kickback.
e) Do not use chain or toothed saw
blades. Such attachment tools frequent-
ly cause a kickback or loss of control
over the electric tool.
f) Avoid blocking the cutting disc or press-
ing down too hard. Do not make any
excessively deep cuts. Overloading the
cutting disc increases wear and its ten-
dency to tilt or block and, with that, to
kickback or break the grinder.
g) If the cutting disc jams, or you interrupt
your work, switch the device off and
hold it until the disc has come to a full
stop. Never try to pull the cutting disc
out of the cut while it is still running,
because it can kick back. Identify and
correct the cause of the jamming.
h) Do not switch the electric tool on again
as long as it is in the workpiece. Al-
low the cutting disc to irst reach its full
rotational speed before you carefully
resume with the cutting. Otherwise, the
disc may catch, spring away from the
workpiece or cause a kickback.
i) Support plates or workpieces to reduce
the risk of kickback from a jammed cut-
ting disc. Large workpieces may bend
under their own weight. The workpiece
must be supported on both sides of the
disc, near the cutting disc as well as
also at the edge.
