Fitting the vacuum hose (see figure C)

• Insert the vacuum hose (17) firmly into the hose adapter (2).

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.
