ADDITIONAL SAFETY RULES
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
breakage. 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.
Additional special safety instructions for abrasive cutting
a) Avoid any blockage to the cutting disc or high contact pressure. Do not make any
excessively deep cuts. Overloading the cutting disc increases the stress and likelihood of
canting or blocking and thus the possibility of a kickback or a breakage of the grinding tool.
b) Avoid the area in front of and behind the rotating cutting disc. When you move the
cutting disc away from yourself in the workpiece, it is possible, in the event of a kickback,
that the electrical tool along with the rotating disc is thrown out directly towards you.
b) If the cutting disc jams or you stop working, switch the tool off and hold it steadily in
the workpiece until the disc has completely stopped turning. Never attempt to pull a
rotating cutting disc out of a cut. This could lead to kickback. Identify and remove the
cause of the jam.
d) Do not switch the power tool back on while it is located in the workpiece. Allow the
cutting disc to reach its full speed before you carefully continue the cut. Otherwise, the disc
can jam, jump out of the workpiece or cause a kickback.
e) Support boards or large workpieces to reduce the risk of the cutting disc jamming and
causing a kickback. Large workpieces can bend under their own weight. The workpiece
must be supported on both sides of the disc: both in the vicinity of the cutting disc and also
at the edge.
f) Be particularly careful when making pocket cuts into existing walls or other obscured
areas. The inserted cutting disc may cut into gas or water pipes, electrical wiring or other
objects that can cause kickback.
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 accessory 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.
