Fitting the vacuum hose

Extraction function (see figure X)

Push the vacuum hose (16) into the hose connection piece (2) and turn it as far as possible in the direction of rotation .

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 X)

The vacuum cleaner 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.

Note: Only use the blowing hose (32) (accessory) for the blowing function. The vacuum hose supplied must not be used for blowing.

Switch on the vacuum cleaner for at least 5 seconds (GAS 15: On/off switch (4) to "on"; GAS 15 PS: Mode selector switch (4) to the "vacuuming" symbol) to clean the vacuum hose (16) of dust deposits.
Turn the vacuum hose (16) as far as possible in the direction of rotation and pull it out of the hose connection piece (2).
Push the blowing hose (32) into the hose connection piece (12) and turn it as far as possible in the direction of rotation .
