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 grind-
ing 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 kickback 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 there is a kickback.
c)
Avoid the area in front of and behind the
rotating cutting disc.
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. Avoid allowing the accesso-
ry 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 bounc-
es. This can cause a loss of control or kickback.
e)
Do not use a toothed or chain saw blade or
a segmented diamond-coated disc with more
than 10 mm wide slits.
Such accessory tools
cause a kickback or loss of control over the
power tool.
f)
Avoid cutting disc jams or excessive contact
pressure. Do not make any excessively deep
cuts.
Overloading the cutting disc increases the
stress and likelihood of tilting or blocking and
thus the possibility of a setback or a breakage
of the grinding tool.
g)
If the cutting disc jams or you stop working,
switch the tool off and hold it steady 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.
h)
Do not switch the power tool back on as long
as it is in the workpiece. Allow the cutting disc
to reach its full speed before you carefully
continue the cut.
Otherwise, the disc may jam,
jump out of the workpiece or cause kickback.
i)
Support panels or large workpieces to re-
duce 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, namely in the
vicinity of the cut and also at the edge.
j)
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.
Supplementary notes

Diamond-coated, disc diameter 85 mm, disc
thickness max. 1.8 mm
