Wear hearing protection when drilling.

Exposure to

noise can cause hearing loss.

When the application tool jams, stop applying pressure
and switch the power tool off.

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 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 37).
