# Fitting the vacuum hose (see figure B)

Attach the vacuum hose (21) to the hose adapter (2) and turn it clockwise as far as it will go.

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.
