Mounting the Vacuum Hose

Vacuuming function

Insert the vacuum hose 17 into the hose connection piece 2 and turn it all the way in clockwise direction.
Note: While vacuuming, an electrostatic charge develops in the vacuum hose and accessories caused by the friction of the dust, which the operator could experience in the form of static discharging (dependent on environmental influences and physical perception). As a general rule, Bosch recommends using an anti-static vacuum hose (accessory) when vacuuming fine dusts and dry materials.
