4.3 Noise information and vibration values in accordance with EN 62841
The sound pressure and vibration values given in these instructions were measured in accordance with a
standardized test and can be used to compare one power tool with another. They can also be used for a
preliminary assessment of exposure.
The data given represent the main applications of the power tool. However, if the power tool is used for
different applications, with different accessory tools, or is poorly maintained, the data can vary. This can
significantly increase exposure over the total working period.
An accurate estimation of exposure should also take into account the times when the tool is switched off, or
when it is running but not actually being used for a job. This can significantly reduce exposure over the total
working period.
Identify additional safety measures to protect the operator from the effects of noise and/or vibration, for
example: maintaining the power tool and accessory tools, keeping the hands warm, organization of work
patterns.

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.
5.1.1 Setting up the drill stand
1. Slacken the screw at the top at the brace and the screw at the bottom at the pivot joint of the rail.
2. Bring the rail into the vertical position.
3. Tighten the screw at the top at the brace and the screw at the bottom at the pivot joint of the rail.
