2.6.3 Workplace safety
•
Secure the work area also behind openings
and cutouts.
Unsecured work areas can endanger you and
other people.
•
Watch out for open and concealed electric-
ity cables, and water and gas pipes. Use
suitable detectors to find concealed utility
pipes and cables, or contact the local utility
company for advice.
Contact with electricity cables can cause fires
and an electric shock. Damage to a gas pipe
can cause an explosion. Penetrating a water
pipe causes damage to property or could cause
an electric shock.
•
Do not use the power tool near flammable
materials.
Sparks could ignite these materials.
•
Avoid causing situations where other people
can stumble or trip.
Tripping over cables can cause serious injuries.
•
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.
•
When carrying out drilling work that requires
the use of water, route the water away from
the work area or use a liquid collection
device.
Such precautions keep the work area dry and
reduce the risk of an electric shock.
•
Inform and consult the responsible structur-
al engineer, architect or the responsible site
engineer about planned drilling.
Cut through reinforcement only with the approval
of a structural engineer.
•
When drilling through walls or ceilings,
ensure that people and work areas on the
other side are protected.
The core drill bit can extend beyond the drill
hole and the drilled core can fall out on the other
side.
•
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, minerals
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 respi-
rator with filter class P2 or P3
(to EN 149:2001).
Observe the relevant regulations in your country
for the materials to be machined.
2.6.4 Electrical safety
•
The power tool may only be used for wet
drilling if operated with a perfectly function-
ing PRCD personal protection switch (see
page 41).
•
Before each use, check the power tool,
connection 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 electric
shock.
•
Only use extension cables suitable for the
machine's power consumption and which
have a minimum core cross-section of
1.5 mm
. If you use a cable drum, always
2
completely unwind the cable.
The rolled up cable can heat up and start to
burn.
