# Dry vacuuming

## Vacuuming up Dust Deposits

- To switch on the dust extractor, briefly press the on/off button (4).
- To switch off the dust extractor, press the on/off button (4) again.

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

- There must be a sufficient air exchange rate (L) 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 dust extraction adapter (18).
- Insert the dust extraction adapter (18) 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 (26) of the dust extraction adapter (18) must be opened. Only then can the semi-automatic filter cleaning (SFC) work without any problems.
To do this, turn the ring above the false air intake (26) until the opening is at its maximum size.

- To activate the automatic start/stop function of the dust extractor, briefly press the on/off button (4).
- To start the dust extractor, switch on the power tool connected to the plug 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, press the on/off button (4).
