5. Safety precautions

5.1 Basic information concerning safety
In addition to the information relevant to safety given in
each of the sections of these operating instructions, the
following points must be strictly observed at all times.
5.2 Take the necessary precautions to make the
workplace safe
Ensure that the workplace is well lit.
Ensure that the workplace is well ventilated.
Keep the workplace tidy. Objects which could cause
injury should be removed from the working area. Untidi-
ness at the workplace can lead to accidents.
Use clamps or a vice to secure the workpiece. The
workpiece is thus held more securely than by
hand and both hands remain free to operate the
tool.
Wear goggles and wear breathing protection during
jobs that create dust.

Do not wear loose clothing, loose long hair or jewelry
as these can become caught up in moving parts. Wear
suitable headgear if you have long hair.
Wear non-slip shoes or boots and always ensure that
you have a secure stance.
When working, keep other persons, particularly chil-
dren, outside the range of the tool.
Do not permit other persons to touch the tool.
Keep other persons away from the area in which you
are working.
Avoid unfavorable body positions when working. Work
from a secure stance and always stay in balance.
To avoid tripping and falling when working, always lead
the supply cord, extension cord and extraction hose
away to the rear..
Concealed electric cables or gas and water pipes pre-
sent a serious hazard if damaged while you are working.
Accordingly, check the area in which you are working
beforehand (e.g. using a metal detector). Avoid con-
tact between your body and earthed / grounded objects,
such as pipes or radiators. External metal parts of the
tool may become live, for example, when an electric
cable is drilled into inadvertently.
