er to the drilling system. Drilling into materials that
present a health hazard (e.g. asbestos) is not per-
missible.
The machine is not intended for use by children,
●
by debilitated persons or those who have received
no instruction or training.
Children must be instructed not to play with the
●
machine.

Dust from material such as paint containing lead,
●
some wood species, minerals and metal may be
harmful. Contact with or inhalation of the dust may
cause allergic reactions and/or respiratory diseases
to the operator or bystanders. Certain kinds of dust
are classified as carcinogenic such as oak and beech
dust especially in conjunction with additives for wood
conditioning (chromate, wood preservative). Mate-
rial containing asbestos must only be treated by spe-
cialists. Where the use of a dust extraction device
is possible it shall be used. To achieve a high lev-
el of dust collection, use a suitable vacuum clean-
er of the type recommended by Hilti for wood dust
and/or mineral dust together with this tool. Ensure
that the workplace is well ventilated. The use of a
dust mask of filter class P2 is recommended. Fol-
low national requirements for the materials you
want to work with.

5.2.1 Mechanical hazards

Follow the instructions concerning care and main-
●
tenance.
Check that the insert tools used are compatible with
●
the chuck system and that they are secured in the
chuck correctly.
Use of unsuitable cutting tools may lead to loss of
●
control and result in injury.
Make sure that the machine is correctly and secure-
●
ly attached to the drill stand.
Do not touch rotating parts.
●
Make sure that all clamping screws are tightened
●
correctly.
After detaching the column extension, the end cap
●
(with built-in, safety-relevant end stop function) must
be refitted to the drill stand.
Check that all core bits are in good condition before
●
use. Do not use deformed or damaged core bits.

5.2.2 Electrical hazards

Protect yourself against electric shock. Avoid body
●
contact with earthed / grounded objects, e.g. pipes,
radiators, cookers and fridges.
Check the condition of the supply cord and its plug
●
connections and have it replaced by a qualified elec-
22

trician if damage is found. Check the condition of the
extension cord and replace it if damage is found.
Check the condition of the machine and its acces-
●
sories. Do not operate the machine or its accessories
if damage is found, if the machine is incomplete or
if its controls cannot be operated faultlessly.
Do not touch the supply cord in the event of it suf-
●
fering damage while working. Disconnect the sup-
ply cord plug from the socket.
Damaged or faulty switches must be replaced at a
●
Hilti service center. Do not use the machine if it can-
not be switched on and off correctly.
Have the machine repaired only by a trained electri-
●
cal specialist (Hilti service center) using original Hilti
spare parts. Failure to observe this point may result
in risk of accident to the user.
Do not use the supply cord for purposes for which
●
it is not intended. Never carry the machine by the
supply cord and never pull the plug out of the sock-
et by pulling the supply cord.
Do not expose the supply cord to heat, oil or sharp
●
edges.
When working outdoors, use only extension cords
●
that are approved and correspondingly marked for
this application.
In the event of a power failure, switch the machine
●
off and unplug the supply cord.
Avoid using extension cords with multiple sockets
●
and the simultaneous use of several machines con-
nected to one extension cord.
Never operate the machine when it is dirty or wet.
●
Dust (especially dust from conductive materials) or
dampness adhering to the surface of the machine
may, under unfavorable conditions, cause an elec-
tric shock to be received. Dirty or dusty machines
should thus be checked at a Hilti service center at
regular intervals, especially used frequently for work-
ing on conductive materials.
If a PRCD is supplied with the power tool, never oper-
●
ate the power tool without the PRCD (GB version:
never operate the power tool without the isolating
transformer).
5.2.3 Thermal hazards
The core bit may become hot during use. Wear pro-
●
tective gloves when changing core bits.
5.3 Requirements to be met by users
The machine is intended for professional use.
●
The machine may be operated, serviced and repaired
●
only by authorized, trained personnel. This person-
nel must be informed of any special hazards that may
be encountered.
Always concentrate on the job you are doing. Pro-
●
ceed carefully and do not use the machine if your full
attention is not on the job.
