4 Technical data
4.1 Diamond core drilling machine
Note
For rated voltage, rated current, frequency and/or input power, refer to the country-specific type
identification plate.
If the tool is powered by a generator or transformer, the generator or transformer’s power output must be
at least twice the rated input power shown on the rating plate of the tool. The operating voltage of the
transformer or generator must always be within +5% and -15% of the rated voltage of the tool.

5.1 Preparations at the workplace
WARNING
Risk of injury. When a drill stand is used, it can spin or topple if it is not adequately secured.
▶ Before using the diamond core drilling machine, secure the drill stand to the work surface with
anchors or with a vacuum base plate.
▶ Use only anchors suitable for the base material and comply with the anchor manufacturer's
instructions.
▶ Use a vacuum base plate only when the work surface is suitable for securing the drill stand by the
vacuum method.
