When restarting a core drill jammed in the workpiece,
check that the application tool rotates freely before
starting. If the application tool is jammed, it may not
start, may overload the power tool, or may cause the
core drill to release from the workpiece.
When securing the drill stand with a vacuum plate to
the workpiece, make sure that the surface is smooth,
clean and non-porous. Do not secure the drill stand to
laminated surfaces such as tiles and coated composite
materials. If the surface of the workpiece is not
smooth, flat or well affixed, the vacuum plate may pull
away from the workpiece.
Ensure there is sufficient vacuum level before and dur-
ing drilling. If the vacuum level is insufficient, the vac-
uum plate may become detached from the workpiece.
Never perform overhead and wall drilling when the
machine is only fastened using the vacuum plate. If the
vacuum is lost, the vacuum plate will release from the
workpiece.
When drilling through walls or ceilings, ensure to pro-
tect persons and the work area on the other side. The
core bit may extend through the hole or the core may
fall out on the other side.
Do not use this tool for overhead drilling with fluid sup-
ply. Fluids entering the power tool will increase the risk
of electric shock.
Have the protective cable bushing replaced immedi-
ately when damaged. A defective protective cable
bushing can lead to overheating of the machine.
Special safety instructions.
Wear personal protective equipment. Depending on the
application, use a face shield, safety goggles or safety
glasses. Wear ear protection. The safety glasses must
be capable of protecting against flying particles gener-
ated by the various different operations. Prolonged
exposure to high intensity noise may cause loss of hear-
ing.
Do not touch the sharp edges of the core drill bit. Dan-
ger of injury.
To avoid injuries, check the core drill bits prior to start-
ing the work. Use only undamaged core drill bits that
are not deformed. Damaged or deformed core drill bits
can cause serious injury.
Before putting into operation: Mount the contact pro-
tector to the machine.
Always secure the machine with the supplied
safety strap. Especially on inclined or uneven
surfaces there is risk of unsecured machines tip-
ping over.
When working overhead, beware of falling objects,
such as cores or chips.
When working overhead or on vertical surfaces, the
coolant container must not be used. Use a coolant spray
instead. Liquids penetrating your electric power tool
may cause electric shock.
Avoid touching the drilled core that is automatically
ejected by the centering pin when the working proce-
dure is finished. Contact with the core when it is hot,
or if it falls, can cause personal injuries.
Operate the power tool only from grounded sockets that
comply with the specifications. Do not use any connec-
tion cables that are damaged; use extension cables
with a grounding contact that are checked at regular
intervals. A ground conductor without continuity can
cause an electric shock.
To prevent injuries, always keep your hands, clothing,
etc. away from rotating swarf. The swarf can cause inju-
ries. Always use the chip guard.
Do not attempt to remove the cutting tool if it still turns.
This can lead to serious injuries.
Beware of any concealed electric cables, gas or water
conduits. Check the working area before commencing
work, e. g. with a metal detector.
Do not work materials containing magnesium. Danger
of fire.
Do not work CFP (carbon-fiber-reinforced polymer) and
materials containing asbestos. These materials are con-
sidered carcinogenic.
Do not rivet or screw any name-plates or signs onto the
power tool. If the insulation is damaged, protection
against an electric shock will be ineffective. Adhesive
labels are recommended.
Do not overload the power tool or the storage case and
do not use it as a ladder or stand. Overloading or stand-
ing on the power tool or the storage case can lead to
the upward shifting of the centre of gravity of the
power tool or the storage case, and its tipping over.
Do not use accessories which are not specifically
designed and recommended by the power tool manu-
facturer. Safe operation is not ensured merely because
an accessory fits your power tool.
Clean the ventilation openings on the power tool at reg-
ular intervals using non-metal tools. The blower of the
motor draws dust into the housing. An excessive accu-
mulation of metallic dust can cause an electrical hazard.
Before storage: Remove the application tool.
Store the power tool only in the case or packaging.
Before putting into operation, check the mains connec-
tion and the mains plug for damage.
Always operate the power tool with together with a
PRCD personal protection switch (*).Before beginning
to work, always check the proper functioning of the
PRCD personal protection switch (*) (see page 25).
Hand/arm vibrations
The vibration emission level given in this information
sheet has been measured in accordance with a stand-
ardised test given in EN 62841 and may be used to
compare one tool with another. It may be used for a
preliminary assessment of exposure.
The declared vibration emission level represents the
main applications of the tool. However, if the tool is
used for different applications, with different accesso-
ries or poorly maintained, the vibration emission may
differ. This may significantly increase the exposure level
over the total working period.
An estimation of the level of exposure to vibration
should also take into account the times when the tool
is switched off or when it is running but not actually
