2 Safety
2.1 General power tool safety warnings
WARNING Read all safety warnings, instructions, illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below 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 battery-operated
(cordless) power tool.
Work area safety
Keep work area clean and well lit. Cluttered or dark areas invite accidents.
Do not operate power tools 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 children and bystanders away while operating a power tool. Distractions can cause you to lose
control.
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.
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.
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
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.
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.
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.
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.
Use personal protective equipment. Always wear eye protection. Protective equipment such as a
dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will
reduce personal injuries.
4 English 2215649 *2215649*
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.
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.
Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.
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.
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.
Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore
tool safety principles. A careless action can cause severe injury within a fraction of a second.
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.
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.
Disconnect the plug from the power source and/or remove the battery pack, if detachable, from
the power tool before making any adjustments, changing accessories, or storing power tools.
Such preventive safety measures reduce the risk of starting the power tool accidentally.
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.
Maintain power tools and accessories. 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.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
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.
Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
Service
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.
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.
*2215649* 2215649 English 5
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.
2.3 Additional safety instructions
Personal safety
Do not tamper with or attempt to make alterations to the machine.
The machine is not intended for use by debilitated persons who have received no special training.
Keep the machine out of reach of children.
Do not touch rotating parts. Switch the machine on only after it is in position at the workpiece.
Touching rotating parts, especially rotating accessory tools, can result in injury.
Avoid skin contact with drilling slurry.
Dust from materials such as lead-based paint, certain types of wood and concrete/masonry/stone
containing quartz, minerals or metal can be harmful to health. Contact with or inhalation of the dust can
cause allergic reactions and/or respiratory or other diseases among operators or bystanders. Certain
kinds of dust such as oakwood and beechwood dust are classified as carcinogenic, especially in
conjunction with additives for wood conditioning (chromate, wood preservative). Only specialists are
permitted to handle material containing asbestos. Use as effective a dust removal system as possible.
To achieve a high level of dust collection, use a suitable vacuum extractor of the type recommended by
Hilti for wood dust and/or mineral dust and which is designed for use with this power tool. Make sure
that the workplace is well ventilated. It is advisable to wear a respirator appropriate for the type of dust
generated. Comply with national regulations applicable to the materials you will be working with.
The diamond core drilling machine and the diamond core bit are heavy. There is a risk of crushing parts
of the body. The user and persons in the vicinity must wear suitable protective goggles, a hard hat,
ear defenders, protective gloves and protective footwear while the machine is in use.
Power tool use and care
Make sure that the machine is correctly secured to the drill stand.
Always make sure that an end stop is installed on the drill stand as otherwise the safety-relevant
end-stop function is not implemented.
Check that accessory tools are compatible with the machine’s chuck/drive system and that they
are installed and secured correctly.
Electrical safety
Do not use extension cords with multiple power outlets powering two or more devices in operation
at the same time.
Operate the machine only when it is connected to an adequately rated power supply with a ground
conductor.
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
can become live, for example if you inadvertently damage electric wiring. This constitutes a serious risk
of electric shock.
Make sure that the supply cord cannot be damaged as the carriage advances.
Never operate the machine without the accompanying PRCD (machines without PRCD: Never
operate the machine without an isolating transformer). Test the PRCD each time before use.
Check the machine’s supply cord at regular intervals and have it replaced by a qualified specialist if
found to be damaged. If the machine’s supply cord is damaged it must be replaced with a specially
prepared and approved supply cord available from Hilti Customer Service. Check extension cords
at regular intervals and replace them if found to be damaged. Do not touch the supply cord or
extension cord if it is damaged while working. Disconnect the supply cord plug from the power
outlet. Damaged supply cords or extension cords present a risk of electric shock.
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, lead to electric
shock. Dirty or dusty machines should thus be checked by Hilti Service at regular intervals, especially if
used frequently for working on conductive materials.
6 English 2215649 *2215649*
Workplace
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 static equilibrium of the structure,
especially when steel reinforcing bars or load-bearing components are cut through.
If the drill stand has not been fastened correctly, always move the machine mounted on the drill
stand all the way down in order to prevent the stand from falling over.
Keep the supply cord, extension cord, water hose and vacuum hose away from rotating parts of
the machine.
Use of the water collection system in conjunction with a wet-type industrial vacuum extractor is a
mandatory requirement for wet drilling overhead.
Use of the vacuum securing method without an additional means of fastening is prohibited 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 securing method (accessory) for horizontal drilling.

6.4 Operating diamond core drilling machine without a wet-type industrial vacuum extractor
1. Slowly open the water flow regulator until the water flows at the desired rate.
The diamond core drilling machine can be operated with or without water collection system. With
the water collection system, the cooling water is drained away through a hose, without the water
collection system the water runs off in an uncontrolled manner. For operation with water collection
system, first install the water collection system → page 11.
In both applications, upward drilling is not allowed.
2. Push the ON/OFF switch to the "I" position.
3. Release the carriage lock.
4. Turn the hand wheel until the diamond core bit is in contact with the work surface.
5. When you start drilling apply only light pressure until the core bit has centered itself and only then,
increase the pressure against the working surface.
6. Observe the drilling performance indicator.
Initially, the drilling performance indicator shows orange. Optimum drilling performance is achieved
when the drilling performance indicator shows green. Reduce the pressure against the work
surface if the drilling performance indicator shows red.
6.5 Operating diamond core drilling machine with a wet-type industrial vacuum extractor 9

Danger of electric shock! There is a possibility of water flowing over the motor and cover if the vacuum
removal system is faulty.
Cease operations immediately if the vacuum removal system is not working.
1. Install the water collection system → page 11 and connect the wet-type industrial vacuum extractor.
2. Switch on the wet-type industrial vacuum extractor; do not use automatic mode.
3. Slowly open the water flow regulator until the water flows at the desired rate.
4. Push the ON/OFF switch to the "I" position.
5. Release the carriage lock.
6. Turn the hand wheel until the diamond core bit is in contact with the work surface.
7. When you start drilling apply only light pressure until the core bit has centered itself and only then,
increase the pressure against the working surface.
8. Observe the drilling performance indicator.
Initially, the drilling performance indicator shows orange. Optimum drilling performance is achieved
when the drilling performance indicator shows green. Reduce the pressure against the work
surface if the drilling performance indicator shows red.
6.6 Procedure in the event of the core bit jamming
If the bit jams the safety clutch disengages. The electronic control system then switches the motor off and
subsequently on again; this is done twice without manual intervention by the user. If this does not free the
core bit, the electronic control system switches the motor off for 90 seconds. You can free a jammed bit
manually, as follows:
6.6.1 Using an open-end wrench to free the core bit
1. Unplug the supply cord from the power outlet.
2. Grip the diamond core bit with a suitable open-end wrench close to the connection end and turn the
diamond core bit to free it.
3. Plug the supply cord into the power outlet.
4. Resume the drilling operation.
6.6.2 Using the hand wheel to free the core bit
1. Unplug the supply cord from the power outlet.
2. Free the core bit from the base material by turning the hand wheel.
3. Plug the supply cord into the power outlet.
4. Resume the drilling operation.

6.7 Switching off the diamond core drilling machine 10
WARNING
Risk of personal injury and material damage The diamond core bit fills with water during overhead drilling.
The diamond core drilling machine may become damaged and the risk of electric shock is increased.
As a first step, carefully allow the water to drain away after completing overhead drilling. This is done
by disconnecting the water supply from the water flow regulator and draining the water by opening the
water flow regulator. Do not allow the water to run over the motor and cover.
1. Connect the water flow regulator to the diamond core drilling machine.
2. Remove the diamond core bit from the hole.
3. Lock the diamond core drilling machine with the carriage lock.
4. Switch off the diamond core drilling machine.
5. Switch off the wet-type industrial vacuum extractor, if used.
6.8 Removal of the diamond core drilling machine
1. Unplug the supply cord from the power outlet.
2. See the section headed "Removing the diamond core bit" page 12 for instructions on removing the
diamond core bit.
3. Remove the core, if necessary.
4. Remove the diamond core drilling machine from the working surface.
If you remove the system as a complete unit, after setting it down it is advisable to run the machine
all the way down the rail until the core bit is in contact with the floor. This will help prevent the
diamond core drilling machine from toppling over.
