•
Secure the workpiece.
A workpiece securely held in clamping devices
or a vice is more safely held than in the hand.
•
Avoid dust accumulation in the workplace.
Dusts can easily ignite.
•
Ensure adequate ventilation in closed
rooms.
Risk due to dust and impaired vision.
•
Inform and consult the responsible structur-
al engineer, architect or the responsible site
engineer about planned drilling.
Cut through reinforcement only with the approv-
al of a structural engineer.
•
Before drilling holes drilling objects, check
the rooms concerned for obstructions and
block off this area. Use formwork to secure
the drill core against falling.
•
Dust from materials such as coatings con-
taining lead, several types of wood, miner-
als and metals can be harmful to health and
cause allergic reactions, respiratory diseas-
es and/or cancer.
Asbestos-containing material may only be
machined by specialists.
f Where possible use dust extraction suitable
for the material.
f Ensure the workplace is properly ventilated.
f We recommend wearing a face mask
respirator with filter class P2 or P3
(to EN 149:2001).
Observe the relevant regulations in your country
for the materials to be machined.
2.6.3 Electrical safety
•
Before each use, check the power tool, con-
nection cable and plug for damage.
Damaged equipment is dangerous, and no
longer safe to use.
•
Note the mains voltage! The power source
voltage must match the details given on the
rating plate of the power tool.
•
If using the power tool with mobile genera-
tors, loss of power or atypical behaviour on
switching on is possible.

•
Do not use the power tool if the cable is
damaged. Do not touch the damaged cable
and disconnect the mains plug if the cable is
damaged while you are working.
Damaged cables increase the risk of an elec-
tric shock.
•
Only use extension cables suitable for the
machine's power consumption and which
have a minimum core cross-section of
1.5 mm
2
. If you use a cable drum, always
completely unwind the cable.
The rolled up cable can heat up and start to
burn.
•
Regularly clean the ventilation slots of your
power tool by blowing it out. Never use liq-
uids. Never insert screwdrivers or any oth-
er objects into the ventilation slits. Do not
cover the ventilation slits.
The motor fan draws dust into the housing and
a large accumulation of metal dust can cause
electrical hazards.
•
External electromagnetic interference (e.g.
mains voltage fluctuations, electrostatic dis-
charges) can cause the power tool to switch
off automatically.
In this case, switch off the power tool and then
switch it back on again.
2.6.4 Safety of people
•
Wear personal protective equipment and,
depending on the work situation, use:
Full-face protection, eye protection
or safety glasses/goggles, hard hat
and special apron
Protect yourself against debris thrown
up by wearing a hard hat, safety gog-
gles or face protection and wear an
apron, if necessary.
Hearing protection
The typical A-weighted sound pres-
sure level of this power tool is over
85 dB (A) while working with the tool.
If you are exposed to loud noise for
lengthy periods, there is a risk of hear-
ing damage or even hearing loss.
Anti-vibration safety glove
At a release value A (8) for arm-hand
vibrations of over 2.5 m/s
ing of anti-vibration safety gloves is
recommended.
