# Fitting the Hose

## Extraction Function (see figure E)

To fit, insert the vacuum hose (23) into the hose connection piece (5) and turn it clockwise as far as it will go.

To remove, turn the vacuum hose (23) anticlockwise as far as it will go and pull it out of the hose socket.

Note: The friction generated by the dust in the vacuum hose and accessory during extraction causes an electrostatic charge that the user may experience as static discharge (depending on environmental factors and their physiological state).
Bosch generally recommends using an anti-static vacuum hose (accessory) to vacuum up fine dust and dry materials.

## Blowing Function (see figure F)

- The dust extractor has a blowing function. Do not blow exhaust air out into the open air. Only use the blowing function with a clean hose. Dust can be hazardous to health.

To fit the blow-out hose (24), push the locking mechanism (14) of the extract air cover and open the cover. Insert the blow-out hose (24) into the hose socket (25) until you hear the two snap fasteners (26) click into place.

To remove the blow-out hose (24), push the two snap fasteners (26) inwards and pull out the blow-out hose. Close the extract air cover so that the locking mechanism (14) engages again.
