# Dry vacuuming

## Vacuuming up dust deposits

To switch on the dust extractor, set the mode selector switch (5) to the "extraction" symbol. |
To switch off the dust extractor, set the mode selector switch (5) to the "switch off" symbol. |

## Extracting dust that accumulates from working power tools (see figure H)

- There must be a sufficient air exchange rate in the room when the exhaust air comes back into the room. Be aware of the corresponding national regulations.

The dust extractor has a plug socket with a protective earth contact (3) that can be used to connect an external power tool. Observe the maximum permitted connected load of the connected power tool.

- Fit the extraction adapter (19) see Fitting the extraction adapter (see figure C).
- Insert the dust extraction adapter (19) into the extraction outlet of the power tool.

Note: When working with power tools that have a low air feed into the vacuum hose (e.g. jigsaws, sanders, etc.), the false air intake (32) of the dust extraction adapter (19) must be opened. Only then can the semi-automatic filter cleaning (SFC+) system work without any problems.
To do this, turn the ring above the false air intake (32) until the opening is at its maximum size.

To activate the automatic start/stop function of the dust extractor, set the mode selector switch (5) to the "automatic start/stop" symbol. |
To activate the dust extractor, switch on the power tool that is plugged into the electric socket (3). The dust extractor will start automatically.
To stop dust extraction, switch the power tool off. The automatic start/stop run-on function will run for up to 15 seconds longer in order to extract the remaining dust from the vacuum hose.
To switch off the dust extractor, set the mode selector switch (5) to the "switch off" symbol. |
