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 electricity
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.
•
Inform and consult the responsible
structural 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
containing lead, several types of wood,
minerals and metals can be harmful
to health and cause allergic reactions,
respiratory diseases 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.
2.6.4 Electrical safety
•
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
generators, 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
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
liquids. Never insert screwdrivers or any
other 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.
