which, in accordance with the applicable standards, require to be listed in the operating instructions.
Accordingly, some of the rules listed may not be relevant to this power tool.
2.2.1 General safety precautions for power tools
WARNING Ensure that your read all safety precautions, instructions and technical data with which
this power tool is provided. Failure to follow the instructions below may result in electric shock, fire and/or
serious injury.
Keep all safety precautions and instructions for future reference.
The term “power tool” used in the safety precautions refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.

Work area safety
▶ Keep your work area clean and well lit. Cluttered or dark work areas invite accidents.
▶ Do not operate the power tool in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
▶ Keep bystanders, children and visitors away while operating a power tool. Distractions can cause
you to lose control of the tool.
Electrical safety
▶ The plug on the supply cord of the power tool must match the power outlet. Do not change the
plug in any way. Do not use adapter plugs with earthed (grounded) power tools. Unmodified plugs
and matching power outlets reduce the risk of electric shock.
▶ Avoid body contact with earthed or grounded surfaces such as pipes, radiators, cookers, stoves
and refrigerators. There is an increased risk of electric shock if your body is grounded.
▶ Do not expose the power tool to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
▶ Do not abuse the supply cord. Never use the supply cord for carrying, pulling or unplugging the
power tool. Keep the supply cord away from heat, oil, sharp edges or moving parts. Damaged or
tangled supply cords increase the risk of electric shock.
▶ When operating a power tool outdoors, use only extension cords of a type suitable for outdoor
use. Use of an extension cord suitable for outdoor use reduces the risk of electric shock.
▶ If use of the power tool in a damp environment cannot be avoided, use a ground fault circuit
interrupter. Use of a ground fault circuit interrupter reduces the risk of electric shock.
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 the power tool may result in serious personal injury.
▶ Wear your personal protective equipment and always wear protective glasses. Depending on the
purpose for which the power tool is to be used, wearing safety equipment such as a dust mask, non-skid
safety shoes, hard hat, or hearing protection will reduce the risk of injury.
▶ Avoid accidental starting. Check that the power tool is switched off before you connect it to the
power supply and/or the battery and before picking it up or carrying it. Carrying power tools with
your finger on the switch or plugging in power tools that are already switched on invites accidents.
▶ Remove adjusting keys or switches before turning the power tool on. A tool or a key left attached to
a rotating part of the machine may result in personal injury.
▶ Avoid unaccustomed body positions. Maintain proper footing and balance at all times. This will
allow you to control the power tool better, even in unexpected situations.
▶ Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
▶ If devices are provided for the connection of dust extraction and collection facilities, ensure these
are connected and properly used. The use of a dust removal system can reduce dust-related hazards.
▶ Do not lull yourself into a false sense of security and do not flout the safety rules for power tools,
even if you are familiar with the power tool after using it many times. Caress handling could cause
serious injury within fractions of a second.
Use of the power tool
▶ Do not overload the tool. Use the correct power tool for your application. The correct power tool
will do the job better and more safely within the performance range for which it is designed.
▶ Do not use a power tool if it has a faulty On/Off switch. Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
▶ Disconnect the plug from the power outlet and/or remove a removable battery before making any
adjustments, changing accessories, or storing the tool. This precaution reduces the risk of the power
tool starting accidentally.
▶ Store idle power tools out of the reach of children . 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.
▶ Maintain power tools and accessories carefully. Check that moving parts operate satisfactorily
and do not jam, and whether any parts are broken or so damaged that the correct operation of the
power tool is adversely affected. If parts are damaged, have the parts repaired before using of the
tool. Many accidents are caused by poorly maintained power tools.
▶ Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less likely
to bind and are easier to control.
5
▶ Use power tools, accessories, insert tools, etc. only as described in this manual. Take the working
conditions and the work to be performed into account. Use of the power tool for operations different
from those intended could result in a hazardous situation.
▶ Keep grips and gripping surfaces dry, clean and free from oil and grease. Slippery grips and gripping
surfaces do not allow the power tool to be safely operated and controlled in unforeseen situations.
Service
▶ Have your power tool repaired only by qualified,skilled personnel, using only genuine Hilti spare
parts. The safety of the power tool can thus be maintained.
2.2.2 Diamond drill safety warnings
▶ When performing drilling that requires the use of water, route the water away from the operator’s
work area or use a liquid collection device. Such precautionary measures keep the operator’s work
area dry and reduce the risk of electrical shock.
▶ Operate power tool by insulated grasping surfaces, 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 diamond drilling. Exposure to noise can cause hearing loss.
▶ When the bit is jammed, stop applying downward pressure and turn off the tool. Investigate and
take corrective actions to eliminate the cause of the bit jamming.
▶ When restarting a diamond drill in the workpiece check that the bit rotates freely before starting. If
the bit is jammed, it may not start, may overload the tool, or may cause the diamond drill to release from
the workpiece.
▶ When securing the drill stand with anchors and fasteners to the workpiece, ensure that the
anchoring used is capable of holding and restraining the machine during use. If the workpiece is
weak or porous, the anchor may pull out causing the drill stand to release from the workpiece.
▶ When securing the drill stand with a vacuum pad to the workpiece, install the pad 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 pad may pull away from the workpiece.
▶ Ensure there is sufficient vacuum before and during drilling. If the vacuum is insufficient, the pad
may release from the workpiece.
▶ Never perform drilling with the machine secured by the vacuum pad only, except when drilling
downwards. If the vacuum is lost, the pad will release from the workpiece.
▶ When drilling through walls or ceilings, ensure to protect persons and the work area on the other
side. The bit may extend through the hole or the core may fall out on the other side.
▶ When drilling overhead, always use the liquid collection device specified in the instructions. Do
not allow water to flow into the tool. Water entering the power tool will increase the risk of electric
shock.
2.2.3 Additional safety precautions
Personal safety
▶ Tampering with or modification of the machine is not permitted.
▶ The machine is not intended for use by inexperienced persons who have received no special
training.
▶ Keep the machine out of reach of children.
▶ Avoid touching rotating parts. Switch the machine on only after it is in position at the workpiece.
Touching rotating parts, especially rotating accessory tools, may lead to injury.
▶ Avoid skin contact with drilling slurry.
▶ Dust from materials, such as paint containing lead, some kinds of wood, concrete / masonry / stone
containing silica, and minerals as well as metal, may be injurious to health. Contact with or inhalation of
the dust may cause allergic reactions and/or respiratory or other 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 handled by specialists. Use a dust removal system that is as effective as possible. Accordingly,
use a suitable vacuum cleaner of the type recommended by Hilti for wood dust and/or mineral dust and
which is designed for use with this power tool. Ensure that the workplace is well ventilated. The use
of a dust mask suitable for the particular type of dust is recommended. Observe national regulations
applicable to the materials on which you intend to use the machine.
▶ The diamond core drilling machine and the diamond core bit are heavy pieces of equipment. There is a
risk of crushing parts of the body. The user and any other persons in the vicinity must wear suitable
