e) The external diameter and thickness of the ac-
cessory tool used must comply with the dimen-
sions of the power tool. Incorrectly dimensioned
accessory tools cannot be sufficiently shielded or
controlled.
f) Attachment tools with a thread insert must
match the thread of the grinding spindle exactly.
For attachment tools that are mounted using a
flange, the diameter of the hole on the attach-
ment tool must correspond to the width of the
fitting on the flange. Accessory tools that cannot
be firmly fitted to the power tool rotate unevenly, vi-
brate severely and can lead to a loss of control.
g) Never use damaged accessory tools. Before
each use, check tools such as grinding discs for
chipping and cracks, grinding wheels for
cracks, wear or heavy wear. If the power tool or
the accessory tool in use is dropped, check to
see if it is damaged or use an undamaged ac-
cessory tool. Once you have checked and used
the tool attachment, ensure that you and all oth-
er persons in the vicinity remain outside the
plane of the rotating tool attachment and allow
the device to run for 1 min. at the maximum
speed. Damaged accessories usually break during
the test period.
h) Wear personal protective equipment. Depending
on application, use face shield, safety goggles
or safety glasses. Where appropriate, wear a
dust mask, hearing protection, protective gloves
or a special apron that will keep small grinding
and material particles away from you. The eye
protection must be capable of stopping flying debris
generated by various operations. Dust or breathing
masks must filter the dust generated during use.
Prolonged exposure to high intensity noise may
cause hearing loss.
i)
Ensure that other people remain at a safe dis-
tance from your workspace. Anyone who enters
the workspace must wear personal protective
equipment. Fragments of the workpiece or broken
accessory tools can fly off and cause injury – even
outside the immediate working area.
j)
Hold the power tool by the insulated handles
when you are carrying out work in which the ac-
cessory tool may come into contact with con-
cealed 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 ac-
cessories. If you lose control of the device, the
mains cable can be severed or caught and your
hand or arm pulled into the rotating insert tool.
l)
Never put the power tool down until the acces-
sory tool being used has come to a complete
standstill. The rotating accessory tool can come in-
to contact with the surface and cause you to lose
control of the power tool.
m) Do not run the power tool while carrying it at
your side. Accidental contact of your clothing with
the rotating attachment part could lead to an injury.

n) Clean the ventilation slits of your power tool
regularly. The engine fan draws dust into the hous-
ing and a strong accumulation of metal dust can
cause electrical hazards.
o) Never use the power tool in the vicinity of in-
flammable materials. Sparks can ignite such mate-
rials.
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.
Kick-back and corresponding safety
instructions
Kick-back is the sudden reaction resulting from a
caught or jammed rotating insert tool, such as a grind-
ing disc, grinding wheel, etc. Catching or jamming re-
sults in the rotating insert tool stopping abruptly. As a
result, an uncontrolled electric tool is accelerated
against the direction of rotation of the tool attachment at
the blocking point.
For example, if a grinding disc catches or jams in the
workpiece, the edge of the grinding disc that plunges
into the workpiece can get caught, causing the grinding
disc to break away or kick back. The grinding disc may
either jump toward or away from the operator, depend-
ing on direction of the wheel's movement at the point of
pinching. Abrasive wheels may also break under these
conditions.
Kickback is the result of incorrect or deficient use of the
power tool. It can be prevented by suitable precaution-
ary measures, as described in the following.
a) Hold the power tool firmly in both hands and po-
sition your body and arms so they can absorb
the force of a kickback. Always use the addition-
al handle, if available, so that you have the max-
imum possible control over the kickback force
or reaction forces at full speed. By taking ade-
quate precautions, the operator can stay in control
of the kickback and reaction forces.
b) Never hold your hand close to a rotating acces-
sory tool. The accessory tool could jump out of
your hand if there is 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 accessory
tool to bounce back from the workpiece or jam.
The rotating tool attachment tends to jam at cor-
ners, sharp edges or when it bounces back. This
causes a loss of control or kick-back.
e) Do not use chains or toothed saw blades. Such
accessories often cause a kickback or loss of con-
trol over the power tool.
