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.
•
Before use, check all water-carrying parts
– including those of the accessories – for
perfect working order and leaks.
Leaking water increases the risk of an electric
shock.
2.6.5 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
The wearing of anti-vibration safety
gloves is recommended for a release
value A (8) for arm-hand vibrations of
over 2.5 m/s

.
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).
Wet drilling: Working with wet dia-
mond core drill bits is a grinding pro-
cess, during which extremely fine dust
is produced, which is bound by the
added water. If the used water with the
bound dust is not collected, the bound
dust is re-released after drying. When
drilling materials containing quartz, the
risk of silicosis is very high; therefore,
the machine may therefore only be
used in wet operation.
•
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.
•
Operate the power tool by holding the
insulated gripping surfaces when carrying
out work during which the cutting tool can
hit concealed electrical cables or the tool's
own power lead.
Contact of a cutting tool with a live cable can
also energise metallic parts of the power tool
and result in an electric shock.
•
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.
