i) Ensure that other people remain at a safe dis-
tance to your workspace. Anyone who enters
the workspace must wear personal protective
equipment.
Fragments of the workpiece or broken acces-
sory tools can fly off and cause injury – even
outside the immediate working area.
j) Hold the power tool only by the insulated
handles when you are carrying out work in
which the accessory tool may come into
contact with concealed power cables.
Contact with a live wire may make exposed
metal parts of the power tool live and could
give the operator an electric shock.
k) Keep the power cord away from any rotating
accessories. If you lose control of the appliance,
the cord may get caught or cut and your hand or
arm could get caught in the rotating accessory
tool.
l) Never put the power tool down until the
accessory tool being used has come to a
complete standstill. The rotating accessory tool
could come into contact with the surface and
cause you to lose control of the power tool.
m) Do not leave the power tool running whilst
carrying it. Accidental contact between your
clothing and the rotating accessory tool could
lead to a physical injury.
n) Clean the ventilation slits of your power tool
regularly. The engine fan draws dust into the
housing and a strong accumulation of metal
dust can cause electrical hazards.
o) Never use the power tool in the vicinity of
inflammable materials. Sparks can ignite these
materials.
p) Do not use any accessory tools which require
liquid coolant. The use of water or other liquid
coolants may lead to an electric shock.

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 power
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 in a
workpiece, the edge of the grinding disc 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 additional handle, if available, so that
you have the maximum possible control over
the kickback force or reaction forces at full
speed. By taking adequate precautions, the
operator can stay in control of the kickback
and reaction torques.
b) Never hold your hand close to a rotating
accessory tool. The accessory tool could hit
your hand in the event of a kickback.
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 power 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. Avoid allowing the acces-
sory 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
rebounds off them. This can cause a loss of
control or kickback.
