Eye protection must be able to stop pro-
jected fragments created during various
work activities. The dust mask or respi-
rator must be able to fi lter out particles
created during your activity. Long term
exposure to high intensity noise may lead
to hearing loss.
i) Keep people around you at a safe
distance from the working area. Eve-
rybody who enters the work area
must wear personal protective gear.
Splinters from pieces of work or damaged
accessories may also fl y out and cause
damage far away from the work area.
j) In work situations where the cutting
tool could touch hidden electrical
wires or its own fl exible power cord,
hold the tool only in places where the
holding surface is insulated. When the
cutting tool touches a “live” conductor
the metal parts of the tool may become
“live” and cause injury to the user by
electrical shock.
k) Place the fl exible power cord out of
range of the rotating tool. If you lose
control the fl exible power cord may be
severed or ground away, and your hand
may be pulled into the rotating tool.
l) Never put down the electromechani-
cal tool until the tool fully stops. The
rotating tool may catch on to a surface
and rip the tool out from your control.
m
) Never start the electromechanical tool
when carrying on your side. A chance
touch of the rotating tool may catch on
to your clothing and pull the tool to your
body.
n) Regularly clean the ventilation open-
ings of the tool. The motor fan pulls
dust inside the case and an excessive
accumulation of metal dust may create
an electrical hazard.
o) Do not work with electromechani-
cal tools near fl ammable materials.
Sparks could cause these materials to
catch on fi re.
p) Do not use tools requiring a coolant
liquid. The use of water or other cool-
ant liquids may cause injury or death by
electric shock.
5.2 Other safety instructions
for all work activities
Kick back and related warnings
Kick back is a sudden reaction to the situa-
tion where the rotating disc, support plate,
brush or another tool becomes clamped or
jammed. Clamping or jamming causes the
rotating tool to stop suddenly, which sub-
sequently causes the uncontrollable tool
to move in the opposite direction to the
rotation of the tool from the point where it
became stuck.
For example: if a grinding disc becomes
clamped or stuck in an object, the edge of
the disc entering the jam point may enter
the surface of the material and cause the
disc to be pushed upwards or defl ected.
The disc may jump either towards or away
from the user depending on the direction
of the movement of the disc at the jam-
ming point. In such cases grinding discs
may also crack.
The kick back is the result of the incorrect
usage of the electro-mechanical tool and/or
incorrect work procedures or conditions and
can be prevented by the correct adherence
to the safety provisions described below.
a) Hold the tool fi rmly and maintain
correct positioning of your body and
arms so that you are able to resist the
kick back forces. Always use the aux-
iliary handle if it is included with the
tool, to maintain maximum control
over the kick back or the reactionary
torque when the tool is started. The
user is able to control the reactionary
torque and kick back forces if he does the
following correct safety precautions.
b) Keep your hands away from the ro-
tating tool. The tool may throw back
your hand with the kick back.
c) Do not stand in the place where the
tool could end up if kick back occurs.
Kick back fl ings the tool in the opposite
direction of the movement of the disc at
the jamming point.
d) Pay extra attention when working on
corners, sharp edges, etc. Avoid the
jumping and chopping of the tool.
Corners, sharp edges or jumping have
a tendency to jam the rotating tool and
cause loss of control or kick back.
