A kickback is a consequence of incorrect or faulty
use of the power tool. It can be prevented by the use
of suitable measures, as described below:
• Hold the power tool securely with both hands
and position your body and arms in such a
way that you are able to absorb any kick-
back. Always use the additional handle, if
there is one available, in order to ensure you
have the greatest possible control over kick-
back forces or reaction torque when the tool
is at top speed. The operator is able to master
kickback or reaction forces if they take the
appropriate care.
• Never put your hand close to the rotating
tool. The tool may move over your hand in the
event of kickback.
• Keep your body out of the area that the power
tool would jump to in the event of kickback.
Kickback pushes the power tool in the opposite
direction to the movement of the sanding disc at
the blocked point.
• Be especially careful around corners, sharp
edges etc. Avoid tools bouncing off work
pieces and becoming jammed. The rotating
tool will tend to jam at corners, sharp edges or
when it bumps against something. This will lead
to a loss of control or kickback.
• Do not use chained or toothed saw blades.
Such tools will often cause kickback of the loss
of control over the power tool.
Special safety notes regarding grinding and
abrasive cutting:
• Only use grinding tools permitted for use with
your power tool and the protective hood
designed for use with these tools. Grinding
tools that have not be designed for use with the
power tool cannot be sufficiently shielded and
are thus unsafe.
• The protective hood must be affixed securely
to the electrical tool and set in such a way
that it ensures the maximum level of safety
possible, i.e. the smallest possible area of
the grinding tool is exposed to the operator.
The protective hood should protect the operator
from broken pieces and accidental contact with
the grinding tool.
• Grinding tools may only be used for the pur-
poses recommended. For example: Never
use the side surface of a cutting disc to
grind. Cutting discs are designed to be used to
remove material with the edge of the disc. Lat-
eral forces on these tools may break them.
• Always used undamaged tensioning flanges
in the correct size and shape for the cutting
disc you have selected. Suitable flanges sup-
port the cutting disc and thus reduce the risk of
the disc breaking. Flanges for cutting discs may
differ from flanges for other grinding discs.
• Do not use worn grinding disc from larger
power tools. Grinding discs for larger power
tools are not designed to cope with the higher
revolutions of smaller power tools and may
break.
Further additional safety notes regarding
abrasive cutting:
• Avoid jamming the cutting disc or applying
too high a pressure. Do not carry out any
excessively deep cuts. Overloading the cut-
ting disc increases the pressure and the ten-
dency to tilt or block and thus increases the risk
of kickback or of the disc breaking.
• Avoid the area in front of and behind the rotat-
ing disc. If you operate the device in such a
way that the cutting disc in the work piece is
moved away from you, in the event of kickback,
the power tool and the rotating disc may be
thrown towards you.
• If the cutting disc is jammed or you need to
interrupt your work, switch the power tool
off, and hold it motionless until the disc has
come to a standstill. Never attempt to pull a
still operating cutting disc out of the cut as
this may cause kickback. Investigate and
take corrective actions to eliminate the cause of
the jam.
• Do not switch the power tool back on as long
as it remains stuck in the work piece. Allow
the cutting disc to achieve the full revolu-
tions before you continue to cut carefully.
Otherwise, the disc may get caught, jump out of
the work piece or cause kickback.
• Support panels or large work pieces to mini-
mise the risk of kickback caused by a
trapped disc. Large work pieces may bend
under their own weight. The work piece must be
supported on both sides, near the line of cut
and near the edge.
• Be very carefully when making plunge cuts in
existing walls or in other areas that are diffi-
cult to see. The plunging disc may cut into gas
or water pipes, electrical cables or other objects
and cause kickback.
Special safety notes regarding sandpaper
sanding
• Do not use over dimensioned sanding sheets,
instead following the manufacturer's instruc-
tions regarding size. Sanding sheets that pro-
trude beyond the sanding plate may cause inju-
ries, jamming and tearing of the sheets or cause
kickback.
Special safety notes regarding working with
wire brushes
• Please note that wire brushes will loose wire
bristles during normal operation. Do not
overload the wires by applying too high a
pressure. Flying wire bristles may easily pass
through very thing clothing and/or skin.
• If a protective good is recommended, make
sure that the hood and the wire brush do not
make contact. Wheel and cup brushes may
increase in diameter as a result of pressure and
centrifugal forces.
