Kickback and corresponding safety
instructions
Kickback is a sudden reaction caused when a
rotating grinding disc catches or jams. Catching or
jamming causes the rotating accessory tool to stop
abruptly. 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, the
edge of the grinding disc that is 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 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 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
bounces. This can cause a loss of control or
kickback.
PTS 710 A2
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
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, 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.
