I don't know this model, but for older cylinder vacs, you do normally just screw or click the hose into the socket at the opposite end. For some post-war models such as the late 1970's Electrolux 345, the connector is on the top, and you have click off the cover of the air vent and remove the filter to find it. It is advisable to empty the dust bag, point the hose out of the window, turn it on, and give the hose a few knocks to dislodge the dust it contains before using it in blow mode.
