2.1 Use of the product as directed
The core drilling machine together with the DD-HD 30 drill stand and additional accessories recommended by Hilti
(e.g. the DD AF-CA drilling feed unit) forms an automatic stand-mounted drilling rig suitable for wet core drilling in
reinforced mineral materials. The core drilling machine is electrically powered and is designed for drilling through holes
and blind holes using diamond core bits (it is not suitable for hand-held operation).
The core drilling machine must be mounted on the drill stand and care must be taken to ensure that the drill stand is
securely fastened to the base material using an anchor or vacuum base plate.
The machine is designed for professional use and may be operated, serviced and maintained only by trained,
authorized personnel. This personnel must be informed of any special hazards that may be encountered. The core
drilling machine, drill stand, accessories and core bits may present hazards when by used by untrained personnel,
when handled incorrectly or when used not as directed.
Observe the national health and safety requirements.
Use of a water collection system connected to a wet/dry industrial vacuum cleaner is recommended for drilling in an
upward direction.
An additional means of securing the drill stand must be employed when the machine is secured with the vacuum base
plate (accessory) for horizontal drilling.
Do not use a hammer or other heavy object when making adjustments to the base plate.

NOTE
The vibration emission level given in this information sheet has been measured in accordance with a standardized test
given in EN 61029 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 accessories 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
doing the job. This may significantly reduce the exposure level over the total working period. Identify additional safety
measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep
the hands warm, organization of work patterns.

4 Safety instructions
4.1 General Power Tool Safety Warnings
a)
WARNING
Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result
in electric shock, fire and/or serious injury. Save all
warnings and instructions for future reference.
The term “power tool” in the warnings refers to
your mains-operated (corded) power tool or batteryoperated (cordless) power tool.
4.1.1 Work area safety
Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable
a)
c)
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
Keep children and bystanders away while operating a power tool. Distractions can cause you to lose
control.
4.1.2 Electrical safety
Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce
risk of electric shock.
b) Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
a)
25
Printed: 07.09.2015 | Doc-Nr: PUB / 5209045 / 000 / 02
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase
the risk of electric shock.
e) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.
f) If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk
of electric shock.
c)
en
4.1.3 Personal safety
Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personal injury.
b) Use personal protective equipment. Always wear
eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injuries.
c) Prevent unintentional starting. Ensure the switch
is in the off‐position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energising power tools that have the switch
on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result
in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewellery
or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
collection can reduce dust-related hazards.
a)
4.1.4 Power tool use and care
Do not force the power tool. Use the correct
power tool for your application. The correct power
tool will do the job better and safer at the rate for
which it was designed.
b) Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be
repaired.
c) Disconnect the plug from the power source
and/or the battery pack from the power tool
a)
26
Printed: 07.09.2015 | Doc-Nr: PUB / 5209045 / 000 / 02
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrained users.
e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tool’s operation. If damaged, have the power tool
repaired before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking into
account the working conditions and the work to
be performed. Use of the power tool for operations different from those intended could result in a
hazardous situation.
4.1.5 Service
a)
Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
4.2 Proper organization of the work area
Approval must be obtained from the site engineer
or architect prior to beginning drilling work. Drilling
work on buildings and other structures may influence
the statics of the structure, especially when steel
reinforcing bars or load-bearing components are cut
through.
b) When drilling through walls, secure (cordon off)
the area behind the wall, as material or the core
may fall out on the other side of the wall. When
drilling through ceilings, secure (cordon off) the
area below as drilled material or the core may
drop out and fall down.
c) In order to avoid accidents in which persons fall
and injure themselves, the opening that is created
must be securely and visibly cordoned off.
d) Place the mounting device on a solid, flat and level
surface. If the mounting device can slip or wobble,
the machine cannot be guided smoothly and safely.
e) Check the nature of the surface. Rough surfaces
may reduce the holding power of the drill stand.
Coatings or composite materials may pull away from
the surface while you are working, so that the drill
stand with the core drilling machine are no longer
held securely.
f) Do not overload the mounting device and do not
use it as a substitute for a ladder or platform.
Overloading the mounting device or standing on it
may shift its center of gravity to a higher position,
causing it to tip over.
a)
g) Wear respiratory protection if the work causes
dust.
h) Ensure that the workplace is well ventilated.
i) It is recommended that rubber gloves and nonskid shoes are worn when working outdoors.
j) Keep the supply cord, extension cord, suction
hose and vacuum hose away from rotating parts.
k) Don’t work from a ladder.
l) Keep the workplace tidy. Objects which could
cause injury should be removed from the working area. Untidiness at the workplace can lead to
accidents.
m) Secure the workpiece. Use clamps or a vice to
secure the workpiece. The workpiece is thus held
more securely than by hand and both hands remain
free to operate the machine.
n) Always lead the supply cord and extension cord
away from the power tool to the rear while working. This helps to avoid tripping over the cord while
working.
k)

machine only when the connecting socket is
covered, i.e.when the protective cover cap is fitted. If the protective cover cap is missing, contact
Hilti Service and obtain a replacement. Unplug the
core drilling machine from the electric supply immediately if water enters the connecting socket.
Check to ensure that the connecting socket is
dry before making further use of the core drilling
machine. The connecting socket may fill with water
if it is not covered by the protective cap or if the
connecting plug is not in place, resulting in a risk of
electric shock if the parts are touched.
b) Keep the grips dry, clean and free from oil and
grease.
c) Never leave the machine unattended.
d) Store machines in a secure place when not in use.
When not in use, machines must be stored in a
dry, high place or locked away out of reach of
children.
e) Keep other persons away. Do not allow other persons who are not involved in the work, especially
children, to touch neither the machine nor the
extension cable. Keep these persons away from
the working area.
f) Children must be instructed not to play with the
machine.
g) The machine is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
h) Never operate the machine without the supplied
PRCD (machines without PRCD: Never operate
the machine without an isolating transformer).

q)
damaged parts must be checked carefully to ensure that they function faultlessly and as intended. Check that moving parts function correctly
without sticking and that no parts are damaged.
All parts must be fitted correctly and fulfill all
conditions necessary for correct operation of the
machine. Damaged guards, safety devices and
other parts must be repaired or replaced properly
at an authorized service center unless otherwise
indicated in the operating instructions.
Regularly check the hoses for damage and make
sure that the maximum permissible water supply
pressure of 6 bar is not exceeded.
Avoid skin contact with drilling slurry.
Wear a protective mask during work that generates dust, e.g. dry drilling. Connect a dust removal system. Drilling in materials hazardous to
the health (e.g. asbestos) is not permissible.
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). Material
containing asbestos must only be treated by specialists. Where the use of a dust extraction device is
possible it shall be used. To achieve a high level
of dust collection, use a suitable vacuum cleaner
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. Follow national requirements for the materials you
want to work with.
Use the right tool or machine for the job. Do not
use the tool or machine for purposes for which
it was not intended. Use it only as directed and
when in faultless condition.
Check that all core bits are in good condition
before use. Do not use deformed or damaged
core bits.
When drilling, always maintain a safe distance
from the core bit and do not touch any rotating parts. Always unplug the supply cord before
touching or making any adjustments to the core
bit.
4.2.2 Mechanical
Follow the instructions concerning care and maintenance.
b) Follow the instructions concerning lubrication
and changing core bits.
c) Check that the core bits used are compatible with
the chuck system and that they are secured in the
chuck correctly.
d) Make sure that the machine is correctly and securely mounted on the drill stand.
e) Do not touch rotating parts.

lead to electric shock. Dirty or dusty machines
should thus be checked at a Hilti service center
at regular intervals, especially if used frequently
for working on conductive materials.
f) Before beginning work, check the working area
(e.g. using a metal detector) to ensure that no
concealed electric cables or gas and water pipes
are present. External metal parts of the machine may
become live, for example, when an electric cable is
damaged accidentally. This presents a serious risk of
electric shock.
g) Before beginning drilling, check that there are
no live electric cables present in the area where
drilling is to take place.

9 Disposal
Most of the materials from which Hilti machines or appliances are manufactured can be recycled. The materials must
be correctly separated before they can be recycled. In many countries, Hilti has already made arrangements for taking
back old machines and appliances for recycling. Ask Hilti customer service or your Hilti representative for further
information.
For EC countries only
Disposal of electric appliances together with household waste is not permissible.
In observance of the European Directive on waste electrical and electronic equipment and its implementation in accordance with national law, electrical appliances that have reached the end of their life
must be collected separately and returned to an environmentally compatible recycling facility.
Recommended pretreatment before disposal of drilling slurry
NOTE
The disposal of drilling slurry directly into rivers, lakes or the sewerage system without suitable pretreatment presents
environmental problems. Ask the local public authorities for information about current regulations.

Collect the drilling slurry (e.g. using a wet-type industrial vacuum cleaner)
Allow the drilling slurry to settle and dispose of the solid material at a construction waste disposal site (the
addition of a flocculent may accelerate the separation process).
The remaining water (alkaline, pH value > 7) must be neutralized by the addition of an acidic neutralizing agent or
diluted with a large volume of water before it is allowed to flow into the sewerage system.
