Kickback and corresponding safety
instructions
Kickback is a sudden reaction caused when a
rotating accessory tool, e.g. grinding disc, grinding
plate, wire brush, etc., catches or jams. Catching or
jamming leads to an abrupt stop of the rotating ac-
cessory tool. If this happens, an uncontrolled pow-
er tool turns rapidly against the direction of rotation
of the accessory tool caught in the blockage.
If, for example, a grinding disc catches or jams, the
edge of the grinding disc that is projecting into the
workpiece can get caught and break off the grinding
disc or cause a kickback. The grinding disc can
then fly in the direction of the operator or away from
him, depending on the direction of rotation of the
disc at the blockage. This can also break grinding
discs.
A kickback is caused by improper or incorrect use
of the power tool. This can be avoided by taking
proper precautions as given below.
a) Hold the power tool firmly in both hands and
position your body and arms so they can
absorb the force of A kickback. Always use the
auxiliary handle, if available, so that you have
the maximum possible control over the kick-
back force or reaction forces at full speed.
By taking adequate precautions, the operator can
stay in control of the kickback and reaction forces.
b) Never hold your hand close to a rotating
accessory tool. The accessory tool could jump
out of your hand if kickback occurs.
c) Avoid having any part of your body in the
region in which the power tool is likely to
move in event of a kickback. The kickback will
force the electrical tool in the opposite direction
to the direction of rotation of the grinding disc
at the blockage.
d) Take special care when working near corners,
sharp edges, etc. Do not allow the accessory
tool to bounce back from the workpiece or
jam. The rotating accessory tool is more likely to
jam in corners or sharp edges or if it bounces.
This can cause a loss of control or kickback.
e) Do not use chains or toothed saw blades.
Such accessories often cause a kickback or loss
of control over the power tool.

Special safety instructions for
grinding and abrasive cutting
a) Use only the grinding accessories approved
for your power tool and the appropriate blade
guard for these grinding tools. Grinding tools
which are not designed for the power tool cannot
be sufficiently shielded and are unsafe.
b) Offset grinding discs must be fitted so that the
grinding surface does not protrude over the
edge of the blade guard. An improperly fitted
grinding disc which protrudes over the edge of
the blade guard cannot be properly guarded.
c) The blade guard must be securely mounted
on the power tool and adjusted to ensure
maximum safety so that the smallest possible
amount of the grinding tool is exposed to
the operator. The blade guard is designed to
protect the operator from fragments, accidental
contact with the grinding tool and sparks that
could ignite clothing.
d) Grinding tools should only be used for the
recommended applications.
For example: never grind with the side sur-
face of a cutting disc. Cutting discs are de-
signed to remove material with the edge of the
disc. Any lateral application of force on these
grinding tools can lead to a breakage.
e) Always use an undamaged clamping flange
of the correct size and shape for the selected
grinding disc. Suitable flanges support the
grinding disc and reduce the risk of disc break-
age. Flanges for cutting discs can be different to
flanges for other grinding discs.
f) Do not use worn grinding discs from larger
power tools. Grinding discs for larger power
tools are not designed for the higher rotational
speeds of smaller power tools and can break.
