Contact with a live power line can
electrically charge the device's metallic
parts and lead to electric shock.
• Keep the power cord away from
rotating insertion tools. If you lose
control of the device, the power cord may
be cut or caught and your hand or arm
may come into contact with the rotating
insertion tool.
• Never put the device down before the
insertion tool has completely stopped
moving. The rotating insertion tool may
come into contact with the material hol-
der, which can lead to a loss of control.
• Make sure the machine is not on while
you are carrying it. If your clothing
accidentally comes into contact with the
rotating insertion tool, it may be caught
and pull the insertion tool toward your
body.
• Clean the device's ventilation slots
regularly. The motor fan pulls dust into
the housing, and a heavy build-up of
metal dust can lead to electrical dangers.
• Do not use the device in the vicinity of
flammable materials. Sparks may ignite
such materials.
• Do not use any insertion tools that
require a liquid cooling agent. Using
water or other liquid cooling agents can
lead to electric shock.
Machine kickback and appropriate
safety measures
Machine kickback is a sudden reaction
resulting from a caught or blocked insertion
tool, such as a grinding or cutting disc, that is
in rotation. Catching or blocking leads to an
abrupt stoppage of the rotating insertion tool.
This will cause you to lose control of the
insertion tool as it accelerates against the
rotational direction at the blocked point.
If, for instance, a grinding disc gets caught or
blocked in the work piece, the edge of the
grinding disc that is grinding into the work
piece can break off or cause a kickback.
The grinding disc will then move toward or
away from the operator, according to the
disc's rotational direction at the blocked
point. This may also cause the grinding disc
to break.
A kickback is the result of an improper or
erroneous use of the device. It can be pre-
vented by applying safety measures, as
described in the following.
• Hold the device tightly and place your
body and arms in a position that
allows you absorb the force of a kick-
back. Always use the auxiliary handle,
if one is provided, in order to have the
highest possible degree of control
over the force of kickbacks or reaction
torque at high rotational speeds. With
proper safety measures, the operator can
control the force of kickbacks and torque.
• Never put your hands in the vicinity of
rotating insertion tools. If a kickback
occurs, the insertion tool may come into
contact with your hand.
• Avoid putting your body in the area
where the device might be moved in
the case of a kickback. A kickback cau-
ses the device to be forced in the direc-
tion opposite to the movement of the
grinding disc against the block point.
• Exercise special care when working
on corners and sharp edges. Where
applicable, prevent the insertion tool
from recoiling and jamming. At corners,
sharp edges or when recoiling, rotating
insertion tools have a tendency to jam.
This causes a loss of control or a
machine kickback.
• Do not use chain- or toothed saw
blades. Such insertion tools often cause
kickback or loss of control over the
device.
Special safety guidelines for grind-
ing and cutting
• Use only grinding tools that are ap-
proved for your device and protective
covers intended for these grinding
tools. Grinding tools that are not
intended for the device cannot be ade-
quately shielded and are unsafe.
