2.7.3 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.
•
External electromagnetic interference (e.g.
mains voltage fluctuations, electrostatic
discharges) can cause the power tool to
switch off automatically.
In this case, switch off the power tool and then
switch it back on again.
•
Do not use any insert tools which require
liquid coolant.
The use of water or other liquid coolants could
result in an electric shock.
2.7.4 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
2
, the wearing
of anti-vibration safety gloves is rec-
ommended.
Non-slip safety footwear
Dust mask, half-face filter mask or
face mask respirator
Inhaling fine mineral dust can cause
health damage. We recommend wear-
ing a face mask respirator with filter
class P2 or P3 (to EN 149:2001).
Working with dry diamond core drill
bits is a grinding process in which ex-
tremely fine dust is produced. When
cutting materials containing quartz
there is a very high risk of silicosis;
in this case the machine should only
be used in conjunction with a suitable
dust extractor (e.g. a special BAIER
dust extractor).
•
Ensure other people keep a safe distance
from your work area. Any person entering
the work area must be wearing personal
protective equipment.
Broken pieces of the workpiece or broken insert
tools can fly off and cause injuries, even outside
the immediate work area.
•
Keep the mains power lead away from
rotating insert tools.
If you lose control of the tool, the mains power
lead can be cut or caught and your hand or arm
can be pulled into the rotating insert tool.
•
Never put down the power tool until the
insert tool has come to a complete standstill.
The rotating insert tool can come into contact
with the surface on which the power tool is
placed, which could cause you to lose control of
the power tool.
•
Do not leave the power tool running while
you are carrying it.
Your clothing can get caught by inadvertent
contact with the rotating insert tool and the
insert tool can drill into your body.
•
If the machine is switched on, do not direct
insert tools towards your own or other
people's bodies. Do not touch or take hold
of the tools.
