When securing the drill stand with a vacuum plate to
the workpiece, install the vacuum plate on a smooth,
clean, non-porous surface. Do not secure to laminated
surfaces such as tiles and composite coating. If the
workpiece is not smooth, flat or well affixed, the vac-
uum plate may pull away from the workpiece.
Ensure there is sufficient vacuum level before and dur-
ing drilling. If the vacuum is insufficient, the plate may
release from the workpiece.
Never perform overhead and wall drilling with the
machine secured by the vacuum plate only. If the vac-
uum 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 water
supply. Water entering the power tool will increase the
risk of electric shock.
Special safety instructions.
Do not use a damaged power tool. Before each use of
the power tool, check the housing and other compo-
nents for damage such as cracks or breakage.
Have the protective cable bushing replaced immedi-
ately when damaged. A defective protective cable
bushing can lead to overheating of the machine.
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 swarf protector.
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 with materials containing magnesium.
Danger of fire.
Do not work with CFRP (carbon-fiber-reinforced poly-
mer) and materials containing asbestos. These materi-
als are considered 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.
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.
Do not transport the machine with lifting equipment.
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 32).
Vibration and noise emission values
The vibration and noise emission values given in these
instructions have been measured according to a meas-
urement method standardised in EN 62841 and can be
used to compare power tools with each other. They are
also suitable for a preliminary assessment of vibration
and noise exposure.
The given vibration and noise emission values rep-
resent the main applications of the power tool.
