Observe the operating instructions and the national
regulations for the installation and operation of the AC
generator.
These appliances are not intended for use by persons
(including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowl-
edge, unless they have been given supervision or
instruction concerning use of the appliance by a person
responsible for their safety.
Children should be supervised to ensure that they do
not play with the appliance.
Safety instructions.
When performing drilling that requires the use of a
fluid, route the fluid away from the operator’s work
area or use a fluid collection device.
Such precaution-
ary measures keep the operator’s work area dry and
reduce the risk of electrical shock.
Operate the power tool by the insulated grasping sur-
faces, when performing an operation where the cutting
accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a “live” wire may make
exposed metal parts of the power tool “live” and could
give the operator an electric shock.
Wear hearing protection when drilling. Exposure to
noise can cause hearing loss.
When the core bit is jammed, stop applying downward
pressure and turn off the tool.
Check the cause of the
jam and apply corrective action to eliminate the cause
of the jamming application tool.
When restarting a core drill jammed in the workpiece,
check that the core bit rotates freely before starting.
If
the core bit 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, 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 fluid sup-
ply.
Fluids entering the power tool will increase the risk
of electric shock.
Special safety instructions.
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 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 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. 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.
