Safety
Core drilling systems may only be used by authorized personnel. You can find information on authorized personnel in the “Core drilling safety manual/system description”.
General safety information
WARNING
Read all safety information and instructions. Failure to comply with the safety information and instructions may cause electric shock, fire, and/or serious injury.
Keep all safety information and instructions for future reference.
INFORMATION
The term “power tool” used in the safety information refers to mains-operated power tools (with mains cable) and battery-operated power tools (without mains cable).
Workplace safety

• Keep your workplace clean and well-illuminated. Disorganized or dark workplaces can lead to accidents.
• Do not work with the power tool in potentially explosive areas containing combustible liquids, gases or dust. Power tools generate sparks that can ignite dust or vapors.
• Keep children and other people away when operating the power tool. You risk losing control of the equipment if you are distracted.

Electrical safety

• The plug for the power tool must fit into the socket. The plug must not be modified in any way. Do not use adapter plugs with earthed power tools. Unmodified plugs and the appropriate sockets reduce the risk of electric shock.
• Avoid physical contact with earthed surfaces such as pipes, heaters, stoves, and refrigerators. There is an increased risk of electric shock if your body is earthed.
• Do not expose your power tool to rain or moisture. Ingress of water into a power tool can increase the risk of electric shock.
• Do not misuse the cable to carry the power tool or hang it up, or pull the plug out of the socket. Keep the cable away from heat, oil, sharp edges or moving device parts. Damaged or entangled cables increase the risk of electric shock.
• If you are working with a power tool outdoors, only use extension cables that are also suitable for outdoor use. Using an extension cable suitable for outdoor use reduces the risk of electric shock.
• Use a residual current circuit breaker if operating the power tool in a damp environment is unavoidable. Using a residual current circuit breaker reduces the risk of electric shock.

Personal safety

• When operating the power tool, be attentive, pay attention to what you are doing, and use common sense. Do not operate power tools when you are tired or under the influence of drugs, alcohol or medication. A moment of carelessness when operating the power tool can lead to serious injury.
• Always wear personal protective equipment and protective goggles. Depending on the type and operation of the power tool, wearing personal protective equipment, such as a dust mask, anti-slip safety shoes, hard hat or ear protection reduces the risk of injury.
• Avoid inadvertently putting the power tool into operation. Make sure that the power tool is switched off before connecting it to the power supply and/or battery, picking it up or carrying it. If your finger is on the switch when carrying the power tool or you connect the equipment to the power supply when switched on, it can lead to accidents.
• Remove any adjustment tools or wrenches before switching the power tool on. Do not work on a ladder. A tool or wrench in a rotating piece of equipment can lead to injury.
• Avoid working in an unnatural posture. Ensure that you have a secure footing and keep your balance at all times. This allows you to better control the power tool in unexpected situations.
• Wear suitable clothing. Do not wear loose clothing or jewelry. Keep hair, clothing, and gloves away from moving parts. Loose clothing, jewelry or long hair can be caught by moving parts.
• If dust extraction and collection devices can be fitted, make sure that they are connected and used correctly. Using a dust extraction system can reduce hazards from dust.

Use and handling of the power tool

• Do not overload the device. Use the appropriate power tool for your work. With the appropriate power tool, you can work better and more safely in the specified power range.
• Do not use a power tool if the switch is faulty. A power tool that can no longer be switched on and off is dangerous and must be repaired.
• Disconnect the plug from the socket and/or remove the battery before making device settings, changing accessories or putting the device away. This precautionary measure prevents the power tool from unintentionally starting.
• When not in use, store the power tool out of the reach of children. Do not allow people to operate the device who are not familiar with it or who have not read these instructions. Power tools are dangerous when used by inexperienced people.
• Maintain power tools with care. Check whether moving parts are working properly and do not jam, and whether parts are broken or damaged in such a way that the function of the power tool is impaired. Repair any damaged parts before using the equipment.
• Many accidents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Carefully maintained cutting tools with sharp edges are less likely to jam and are easier to guide.
• Use power tools, accessories, insertion tools, etc. under these instructions. Take the working conditions and the activity to be carried out into account. Using power tools for applications other than those for which they are intended can lead to dangerous situations.

Service

• Only have your tool repaired by qualified specialists, and only with genuine spare parts. This guarantees that the safety of the power tool is maintained.

Safety instructions for drilling machines

• Wear ear protection when using drilling machines. Noise exposure can cause hearing loss.
• Use the additional handles supplied with the device. Loss of control of the machine can lead to injuries.
• Hold the device by the insulated gripping surfaces when carrying out work where the insertion tool may hit concealed power lines or its power cable. Contact with a live wire can also make metal device parts “live” and lead to electric shock.

Protection devices and signs on the equipment

• Protection devices
• Protection devices may only be removed when the equipment is switched off, has been disconnected from the mains supply, and is stationary. Safety components, in particular, may only be removed and re-installed by authorized persons.

Safety elements must be checked to ensure they are in perfect working order before the equipment is brought back into operation.

Overhead drilling

• Drilling upwards (overhead drilling) in wet conditions is permitted only with a suitable water catcher.

Residual risks
There is a risk of severe injury resulting from the residual risks described below.
Diamond segments flying away

• Only start drilling when there are no other people in the danger zone.
• Make sure that a safety distance is complied with.
• If diamond segments break off, replace the diamond coring bit.

• Do not connect or disconnect cables when the electric equipment is running.
• Always hold the portable drilling machine by the handles with both hands when switched on. The thumb and fingers must be closed around the handles.
• Keep the handles clean.

Vibrations
Vibrations can cause circulatory problems or nerve damage.

• Consult a doctor if symptoms occur.

Getting trapped and caught
Items of clothing or long hair could be caught by the rotating cutting tool.

• Do not wear loose clothing when working. Secure long hair in a hair net.

Harmful vapours and aerosol
Inhaling harmful vapours and aerosols can lead to respiratory problems. Inhaling water spray emanating from the machine is hazardous to health.

• Wear a respirator mask.
• Make sure that closed rooms have adequate ventilation.

Poor physical condition

• Do not work under the influence of alcohol, drugs or medication.
• Do not work when overtired.

Cutting tool quality

• Do not use damaged cutting tools.
