Catching and blocking causes the rotating tool bit
to stop abruptly. An uncontrolled electrical power
tool is thereby accelerated against the direction
of rotation of the tool bit at the blockage site.
If for example an abrasive wheel catches or
blocks in the workpiece, the edge of the abrasive
wheel that penetrates the workpiece can be
caught, thereby causing the abrasive wheel to
break away or a kickback. The abrasive wheel
then travels towards or away from the operator
depending on the direction of rotation of the
wheel at the blockage site. Abrasive wheels can
also break in this instance.
A kickback is the result of the incorrect or faulty
use of the electrical power tool. It can be preven-
ted by taking suitable measures, as described
below.
a)Hold the electrical power tool firmly and make
sure your body and arms are in a position so that
you can catch the kickback forces. Always use
the additional handle, if available, to maintain the
best possible control of kickback forces or reac-
tive torques during start-up. The operator can
control the kickback and reactive forces by taken
suitable precautions.b)Never place your hand
near the rotating tool bits. The tool bit can move
across your hand in the event of a kick-
back.c)Avoid the area in front of and behind the
rotating abrasive wheel. The kickback drives the
electrical power tool in a direction that is opposite
to the movement of the abrasive wheel at the
blockage site.d)Work with great care around cor-
ners, sharp edges, etc. Prevent tool bits of the
workpiece from recoiling and jamming. The rotat-
ing tool bit tends to jam when it hits corners,
sharp edges or if it ricochets. This results in the
loss of control or kickback.e)Do not use a chain
or toothed saw blade or a segmented diamond
wheel with more than a 10 mm wide slit. Such
tool bits often cause kickback or the loss of con-
trol of the electrical power tool.f)Avoid the block-
ing of the abrasive wheel or a surface pressure
that is too high. Do not make cuts that are too
deep. Overloading the abrasive wheel increases
its stress level and the likelihood of skewing or
blocking, and thereby the possibility of a kick-
back or breakage of the abrasive element.g)If the
abrasive wheel jams or if you interrupt your work,
switch off the machine and hold it still until the
wheel stops. Never try to remove an abrasive
wheel that is still rotating out of the cut as this
may lead to a kickback. Determine and rectify
the cause of the jam.h)Do not switch the electri-
cal power tool back if it is still in the workpiece.

Allow the abrasive wheel to reach its full speed
before continuing carefully with the cut. Other-
wise the wheel may catch, jump out of the work-
piece or cause a kickback.i)Support plates or
large workpieces to reduce the risk of a kickback
due to a jammed abrasive wheel. Large workpie-
ces can bend under their own weight. The work-
piece must be supported on both sides of the
wheel, both near the cut and at the edge.j)Be
especially careful with "pocket cuts" in existing
walls or other blind areas. If the penetrating abra-
sive wheel cuts into gas or water pipes, electric
cables or other objects, this can cause a kick-
back.
