PREPARING THE VACUUM CLEANER

Fit the telescopic tube (3) into the other end of the hose, and attach the floor nozzle (1) to the end of the tube.

You can adjust the length of the telescopic tube by pushing the locking mechanism (2) down and pulling on the bottom section of the tube until it reaches a suitable length.

When parking, shorten the tube as far as possible.

The vacuum cleaner’s combination nozzle (19) is used for particular vacuuming tasks (see under Use). Remove the floor nozzle and fit the combination nozzle to the end of the telescopic tube.

USE

Pull the cord (15) out of the vacuum cleaner. The cord must not be pulled out any further than the red mark. Plug in and switch the power on.

Press the on/off button (12) to start and stop the vacuum cleaner.

While in use, the suction strength can be regulated by opening and closing the air valve (5) on the handle at the end of the hose.

The suction strength can also be adjusted electronically using the button for controlling suction strength (13). Suction strength increases when the button is turned towards "Max", and reduces when it is turned towards "Min".
