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 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.
▶ 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 and clothing 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.

Battery tool use and care

▶ Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
▶ Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
- When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

HILTI

▶ Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130°C (265°F) may cause explosion.
▶ Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

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.

▶ Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

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.

2.3 Safety instructions for power drills

Safety instructions for all operations

▶ Use the auxiliary handle(s). Loss of control can cause personal injury.
- Hold the power tool by insulated gripping 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.

Safety instructions when using long drill bits

▶ Never operate at higher speed than the maximum speed rating of the drill bit. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.

▶ Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
- Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend causing breakage or loss of control, resulting in personal injury.

2.4 Additional safety instructions

Personal safety

• Do not tamper with or attempt to make alterations to the product.
  The product is not intended for use by debilitated persons who have received no special training.
• Keep clear of rotating parts. Switch the product on only after it is in position at the workpiece. Touching rotating parts, especially rotating accessory tools, can result in injury.
• Do not allow drilling slurry to come into contact with the skin or eyes.
• Dust produced by grinding, sanding, cutting and drilling can contain dangerous chemicals. Some examples are: lead or lead-based paints; brick, concrete and other masonry products, natural stone and other products containing silicates; certain types of wood, such as oak, beech and chemically treated wood; asbestos or materials that contain asbestos. Determine the exposure of the operator and bystanders by means of the hazard classification of the materials to be worked. Implement the necessary measures to restrict exposure to a safe level, for example by the use of a dust collection system or by the wearing of suitable respiratory protection. The general measures for reducing exposure include:
  ▶ working in an area that is well ventilated,
• avoidance of prolonged contact with dust,
• directing dust away from the face and body,
• wearing protective clothing and washing exposed areas of the skin with water and soap.

The diamond core drilling machine and the 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, hearing protection, protective gloves and safety footwear while the product is in use.

Core bits and hole-starting aids can become hot in operation due to friction heat, particularly during dry drilling. Wear protective gloves when removing core bits or hole-starting aids.

- Improve the blood circulation in your fingers by relaxing your hands and exercising your fingers during breaks between working.

If work involves break-through, always secure the area on the side opposite where the work is carried out. Pieces of debris could drop out and/or fall down and injure other persons.

▶ Check that the side handle is fitted correctly and tightened securely. Always hold the tool with both hands on the grips provided. In accordance with the applications for which it is designed, the product produces a high torque. Grip the side handle as far to the outside as possible.

▶ Always support the power tool firmly in preparation for use. This power tool produces high torque. If the power tool is not securely supported at all times during operation loss of control can result and lead to injuries.

- When securing the drill stand to the workpiece, make sure that the drill stand is soundly and securely connected to the workpiece. If the drill stand is not adequately connected to the workpiece, binding of an accessory tool can result in uncontrolled spinning of the drill stand.

Power tool use and care

▶ Ensure that the accessory tools used are compatible with the tool-holder system and that they are correctly secured in the tool holder.
When working with vacuum extraction, always guide the extraction hose to the rear and away from the product. This helps to avoid tripping over the extraction hose while working.
- When taking a break, lay the diamond core drilling machine down on a suitable surface where it will be safe. Wait until the diamond core drilling machine has come to a complete stop before you lay it down.
- Remove the batteries before removing the core or changing tools.
▶ Do not use damaged hoses.
▶ Make sure that the product is correctly and securely mounted on 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.
- Set the drill stand on a firm, flat and horizontal surface. It will not be possible to guide the power tool smoothly and safely if the drill stand can slip or wobble.
- Check the nature of the surface. Rough surfaces may reduce holding power. Coatings or composite materials may pull away from the surface while you are working.

HILTI

- Do not overload the drill stand and do not use the drill stand as a substitute for a ladder or platform. Overloading or standing on the drill stand can shift the drill stand's center of gravity to a higher position, causing it to tip over.

Electrical safety

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 product can become live, for example, when an electric cable is damaged accidentally. This constitutes a serious risk of electric shock.
▶ Never operate the product 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.
Tip the diamond core drilling machine in order to empty a filled core bit. Make sure that the water does not get onto the diamond core drilling machine.

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.
• Do not switch on the diamond core drilling machine until it is in the desired position.
  If the drill stand is not properly fastened, always move the diamond core drilling machine mounted on the drill stand all the way down in order to prevent the stand from falling over.
  In hand-guided mode always hold the diamond core drilling machine securely, with one hand on the side handle and one hand on the main grip with the on/off switch.
• Keep the suction and vacuum hose away from rotating parts.
  ▶ 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 used for horizontal drilling with the vacuum securing method.

DD 150-U-22

▶ Check that the wooden subbase material is suitable for attachment by vacuum. If in doubt, always use the woodscrew or threaded spindle method of securing.

- When wet-drilling upward (drilling into overhead slabs), always use a water collection system whenever possible. In this way you prevent uncontrolled discharge of drilling slurry on to the diamond core drilling machine, your clothing or your skin.

2.5 Careful handling and use of batteries

• Comply with the following safety instructions for the safe handling and use of Li-ion batteries.
  Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or explosion.
  ▶ Use only batteries that are in perfect working order.
  ▶ Treat batteries with care in order to avoid damage and prevent leakage of fluids that are extremely harmful to health!
• Do not under any circumstances modify or tamper with batteries!
• Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C (176 °F).
  ▶ Never use or charge a battery that has suffered an impact or been damaged in any other way. Check your batteries regularly for signs of damage.
  ▶ Never use recycled or repaired batteries.
  ▶ Never use the battery or a battery-operated power tool as a striking tool.
  ▶ Never expose batteries to the direct rays of the sun, elevated temperature, sparking, or open flame. This can lead to explosions.
  Do not touch the battery poles with your fingers, tools, jewelry, or other electrically conductive objects. This can damage the battery and also cause material damage and personal injury.

3.9 Performance ratings on the type identification plate

On the type identification plate you can find various performance data ratings, for example 1400 W and 1650 W S6 40%. This information is to be interpreted as follows:

1400 W

- This performance rating states the product's continuous power rating. You can operate the diamond core drilling machine without time limit at this power.

1650 W S6 40%

- This performance rating states a load cycle at a power of 1650 watts. You can operate the diamond core drilling machine for 4 minutes without interruption at this power. Alternating with low load, also without time limit.

3.10 Active Torque Control (ATC)

The product is equipped with the ATC (Active Torque Control) quick-acting electronic cut-out. If the core bit sticks or stalls, the product will suddenly pivot about its own axis in the opposite direction. ATC detects this sudden pivoting movement of the product and switches the product off immediately.

For ATC to function correctly, the product must be free to pivot. After an ATC cut-out, switch the product off and then on again.

If binding or jamming of the core bit does not cause deflection of the diamond core drilling machine, the motor switches to a pulsation function. This prevents the core bit from seizing completely in the base material. Reduce contact pressure until the core bit can move freely again. The diamond core drilling machine automatically ramps back up to the preset speed.

Display icons Description
[XYK]	The display shows drilling time (diamond core drilling machine time actually drilling since the last reset) at the top and operating hours (diamond core drilling machine switched on) at the bottom. Both figures are shown in hours, minutes and seconds.Context function: Reset drilling time and all other logbook data.
	The display shows remaining drilling time, in hours minutes and seconds, until battery discharge to empty.This forecast is based on energy demand over the last 3 minutes and can differ from reality if operating conditions change.
	The display shows contact pressure during drilling time in %. Applying an optimum contact pressure can optimize performance and service life of the core bit.An up arrow indicates that contact force can be increased to some extent. A down arrow indicates that contact force should be reduced in general.
	The display shows a distribution of drilling time in % for each drilling direction.
	The display shows the duration of use of the respective diameter range setting in %.
	The display shows use of the diamond core drilling machine in hand-held and stand-guided operation in %.
	The display provides an overview of all system products and accessories connected to the diamond core drilling machine.
	This setting enables the unit of measure displayed for diameter to be toggled between millimeter [mm] and inch [in].
	This setting enables the display for speed to be toggled between 'exact diameter' (default), 'diameter range' and 'revolutions per minute' ([rpm]).

Notes on speed:

• Whenever necessary, the unit for diameter can be toggled between millimeter [mm] and inch [in] in the settings. Also see the section headed "Logbook & settings" 19.
• You can adapt the display for the speed setting and toggle between 'exact diameter' (default), 'diameter range' and 'revolutions per minute' ([rpm]. → Also see the section headed "Logbook & settings" +19.
• Depending on core-bit specification, material being drilled, water flow rate, contact pressure and other parameters, increasing or decreasing the speed setting can have a performance-optimizing effect. If the rate of drilling progress diminishes, increasing the diameter setting (speed decreases and torque increases) can have a sharpening effect on the core bit and generally may also be the better choice when the proportion of rebar in the material is high. Conversely, if the material is easily drilled and/or its proportion of rebar is low, a smaller diameter setting can increase the rate of drilling progress.
• If the motor of the diamond core drilling machine is switched on and is idling at no load, the current setting is displayed. The display helps ensure that the parameter settings are suitable for the diamond core bit used.
• In the case of diamond core drilling machines that can be operated in hand-held and stand-guided modes:

The diamond core drilling machine automatically knows when it is being used with or without a drill stand and automatically adapts selectable speed range, torque and drilling performance indicator to the current mode of operation. A switch between drilling with drill stand and hand-held drilling is shown on the multifunction display.

Always comply with the instructions for use in the operating instructions of the core bit specified for wood drilling operations.

For drilling in wooden subbase materials, always use the dry-drilling method and a core bit specified for wood drilling operations. This will avoid excessive damage to the subbase material, and dry drilling chips are easier to collect.
- Wet or damp drilling chips can clog the suction channel. Before wet drilling, check that the water swivel/suction head is as clear of drilling chips as possible. After wet drilling, allow the water swivel/suction head to dry.
▶ Follow the instructions for dry drilling with dust extraction 24.

5.11.2 Performing dry drilling (with dust extraction)

1. Set the side handle to the desired position and secure the side handle. 13
2. Connect the vacuum-cleaner hose to the dust removal adapter of the suction head.
3. Optional: Install and use the telescopic hole-starting aid. 22
4. Establish the power supply to the vacuum cleaner.
5. Configure the system application and select a connection method for the connection between diamond core drilling machine and vacuum cleaner (e.g. Bluetooth).

Follow the instructions for establishing and using a Bluetooth connection in the operating instructions of the vacuum cleaner used.

1. Center the diamond core drilling machine where the hole is to be drilled.
2. Start the motor of the diamond core drilling machine. 18
3. Regulate the contact pressure while observing the drilling performance indicator.

When you switch off the diamond core drilling machine after the drilling operation, allow the vacuum cleaner to keep running for a few seconds. This will allow residual material to be removed from the extraction system.

5.11.3 Performing dry drilling (without dust extraction)

When you perform dry drilling without dust extraction, use slotted core bits. Drilling upward (e.g. drilling into overhead slabs) is permissible only with dust extraction.

Always wear suitable respiratory protection when dry drilling.

1. Set the side handle to the desired position and secure the side handle. 13
2. Optional: Install and use the telescopic hole-starting aid. 22
