Safety

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.
• 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.

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.

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.

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.
• Ensure that the accessory tools used are compatible with the tool-holder system and that they are correctly secured in the tool holder.

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.

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.
• 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.

 Switching off the diamond core drilling machine 12

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.

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:
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.

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.

Removal of the diamond core drilling machine

1.  Unplug the supply cord from the power outlet.
2. Remove the diamond core bit from the BI+ chuck. → page 13
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.
