Regularly check extension cords and replace them if they are damaged. Keep the handles
dry, clean and free of oil and grease.
15 Pull the plug from the socket. When not using the electric tool, before maintenance or
when changing tools, such as saw blades, drills and cutting bits.
16 Do not leave any tool keys inserted. Before switching on, check to see that keys and ad-
justment tools have been removed.
17 Avoid unintentional activation. When plugging the tool in, make sure that the switch is
turned off.
18 Use outdoor extension cords. When outdoors, use only extension cords that are approved
and appropriately marked.
19 Be alert. Pay attention to what you do. Approach your work sensibly. Do not use the electric
tool when you are distracted.
20 Check the electric tool for damage. Before using the electric tool, you must inspect safety
equipment or slightly damaged parts carefully to ensure that they work properly and as in-
tended. Check to see that the moving parts operate freely and don't stick, and to make sure
no parts are damaged. All parts must be mounted properly and meet all the conditions for
ensuring trouble-free operation of the electric tool.
Damaged safety equipment and parts must be properly repaired or replaced by a profes-
sional facility, unless otherwise indicated in the user manual. Damaged switches must be
replaced by a customer service facility.
Never use an electric tool whose switch cannot be turned on and off.
21 Caution. Using other insertion tools and accessories may cause injury.
22 Have your tool repaired by an electrical expert. This electric tool meets applicable safety
requirements. Repairs must be made only by an electrical expert using original replacement
parts. Otherwise accidents many occur.

Special Safety Instructions
Please read and be sure to understand all safety and working information for the drill mo-
tor being used!
The drilling to be carried out with the core drill must be stipulated exclusively by the construction
customer. Neither the ROTHENBERGER employees nor the user can be held liable for damag-
es to the construction statics and consequential damages as a result of this.
Any damages due to cooling water must be excluded as far as possible in advance. Necessary
countermeasures must be taken in coordination with construction site management. Neither the
ROTHENBERGER employees nor the user can be held liable for concealed water damages
(cavities, joints, cracks, invisible pipes etc.).
Do not leave any tools inserted during the installation of the drill rig/drill motor.
Use your personal protective equipment: safety shoes, protective gloves, ear protectors, dust
mask.
Wear close-fitting clothing, remove jewellery and tie back or cover long hair.
The 90 dB noise level is exceeded during drilling. It is, therefore, mandatory to wear suitable ear
protection. Non-observance can lead to significant hearing damage.
The operator must observe the drilling equipment attentively during drilling. Shut down the motor
immediately at the first sign of any disturbances (e.g. cooling water deficiency, loosening of the
drill rig, core bit blocked etc.). Drilling work must only be continued after the cause has been
remedied.
Core hole drilling in ceilings with rooms underneath constitutes a high safety risk. After drilling
through the ceiling there is the danger of the drilling cores crashing down. Suitable counter-
measures must be taken (e,g. safeguard or close off areas, remove drilling cores in an upward
direction): SAFEGUARD THE BUILDING SITE.
