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
attachment. This causes an uncontrolled
electric tool to accelerate in a direction
counter to the rotational direction of the
attachment tool. If, for example, a grind-
ing disc cuts into the workpiece or blocks
it, the edge of the grinding disc that digs
into the workpiece can get caught and,
through that, break off the grinding disc or
cause a kickback. The grinding disc then
moves towards or away from the opera-
tor, 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 wrongly or incorrectly operat-
ing the electric tool. It can be avoided by
suitable cautionary measures, such as
described below.
a) Hold the electric tool very firmly and
bring your body and your arm into a
position in which you can resist the
kickback force. Always use the supple-
mental 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 precau-
tions.
b) Never bring your hands near a rotating
attachment tool. The attachment tool
can run over your hand in the kick-
back.
c) Keep your body away from the area
in which the electric tool would move
during 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 kick-
back.
e) Do not use chain or toothed saw
blades. Such attachment tools fre-
quently cause a kickback or loss of
control over the electric tool.
Special safety instructions for
grinding and cutting
a) Use only grinders which have been
approved for your electric tool and the
protective hood intended for these
grinders. Grinders which are not in-
tended for the electric tool may not be
sufficiently shielded and are unsafe.
b) Depressed Center grinding wheels
must be pre-assembled so that their
surface not above the level of the
edge of the guard stands out. An
improperly mounted grinding wheel,
which extends beyond the level of
the edge of the guard, not sufficiently
shielded.
c) The protective hood must be securely
attached to the electric tool and ad-
justed so that the greatest level of
safety is reached, i.e., the smallest
possible amount of the grinder is ex-
posed to the operator. The protective
hood should protect the operator from
