1. Keep your work area clean and well lit. Disorder or unlit work areas can lead to
accidents.
2. Do not work with the power tool near flammable liquids, gases or dust. Power
tools produce sparks that can ignite dust or fumes, causing explosions.
3. Keep children and other persons away while using the power tool. If you are
distracted, you may lose control of the tool.
4. Be attentive, work with concentration and pay attention to what you are doing.
Do not use a power tool when you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention can result in serious injury.
5. Wear suitable protective equipment and always protective goggles. Wearing
suitable protective equipment such as a dust mask, non-slip safety shoes, hard
hat or hearing protection reduces the risk of injury.
6. Avoid unintentional starting of the machine. Make sure that the power tool is
switched off before connecting it to the power supply. If you have your finger on
the switch when carrying the power tool or connect the machine to the power
supply when it is switched on, this can lead to accidents.
7. Remove setting tools or wrenches before switching on the power tool. A tool or
wrench that is on a rotating device can cause injury.
8. Avoid unusual postures. Ensure a secure footing and maintain your balance at
all times. Do not work on a ladder. This will give you better control of the power
tool in unexpected situations.
5
9. Wear appropriate 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.
10. Do not overload the device. Use the appropriate power tool for your work. With
the appropriate power tool, you will work better and more gently in the specified
power range.
11. Do not use a power tool whose switch is damaged. A power tool that cannot be
switched on and off is dangerous and must be repaired.
12. Unplug the power tool from the wall outlet before making any adjustments,
replacing accessories, or setting aside the power tool. This safety measure
prevents the power tool from starting unintentionally.
13. Keep unused power tools out of reach of children. Do not allow persons to use
the device who are not familiar with it or have not read these instructions. Power
tools are dangerous when used by inexperienced persons.
14. Note that the voltage must not exceed +/-5% of the nominal voltage. Higher
voltages can cause irreparable damage. Note that higher voltage peaks are not
generated when operating the machine via a generator.
15. The plug of the power tool must match the socket. Do not change the plug
under any circumstances. Do not use adapter plugs with grounding-type forces.
Unmodified plugs and matching outlets reduce the risk of electric shock.
16. Avoid body contact with grounded surfaces or grounded components such as
pipes, radiators, ranges, and refrigerators.
17. Do not expose power tools to rain or wet conditions. Water entering a power tool
increases the risk of electric shock.
6
18. Never use the cord to carry or pull the power tool or to unplug the power tool
from the wall outlet. Keep it away from heat, oil, sharp edges or moving parts.
Damaged, crushed or twisted cables increase the risk of electric shock.
19. When using a power tool outdoors, use only an extension cord that is suitable
for outdoor use. Using a cord that is suitable for outdoor use reduces the risk of
electric shock. When using with an extension cord, also make sure that the
extension cord has the same cross-section as the cord on the machine.
20. The use of products such as cutters, grinders, drills that machine sand or other
materials can generate dust and fumes that may contain hazardous chemicals.
Check the type of material you are going to machine and use a suitable
respirator.
21. Non-approved spare parts and any modification are prohibited on our products.
22. If the operation of a power tool in a damp environment is unavoidable, use a
residual current circuit breaker. The use of a ground fault circuit interrupter
reduces the risk of electric shock.
23. If a vacuum cleaner and suction device are required, make sure they are
connected and used properly. The use of a vacuum cleaner can reduce dust-
related hazards.

Technical data
In order to constantly improve the product, our company reserves the right to
change the technical data without prior notice.
Use and care
Only use diamond core bits which are in a sharp and undamaged condition.
Properly maintained diamond core bits with sharp cutting segments do not become
entangled so quickly and are easier to guide.
Use the power tool, accessories and drill bits etc. in accordance with these
operating instructions, taking into account the working conditions and the work to be
performed. Using the power tool for operations other than its intended use could
result in a hazardous situation.
Have your power tool repaired only by qualified personnel and only with original
spare parts.

Precautions
1. ALWAYS wear hearing protection! When using drilling motors, the loud drilling
noise in the working area can cause hearing damage.
2. When drilling, keep a sufficient distance to the core drill and do not touch any
rotating parts. Protect the danger zone and keep children and other persons
away from it. Falling and splashing parts can cause injuries.
3. This diamond core drill is intended for professional use only and may only be
operated by trained personnel. The appropriate use of the core drill includes
drilling rock, reinforced concrete and masonry.
4. The drill motor must be checked regularly (approx. every 6 months) by a
certified electrician in accordance with VDE.
5. When used for overhead drilling, a functional water collection ring must be used.
Make sure that no water can get into the motor.
6. Switch off the core drill immediately if it stops for any reason. After you have
determined and eliminated the cause and performed a visual inspection of the
device and core bit, the core drill can be restarted.
Preparation
Subject the core drill to a brief visual inspection before each start. Also check
whether the network voltage corresponds to the voltage specified on the nameplate
of the tool.
