Vacuum cleaning
Before using the device first roll out a sufficient length of the power cable and plug into the mains
socket. The yellow mark on the electric flex cable is the maximum length that must not be
exceeded.
To switch on the device press the foot pedal button on the casing
with your foot. Pull the device behind you like a sledge when working
with it.
Important!
In a few cases there may be a “whistling” sound at the start. This is
not a fault and the sound goes away after a time.
Do not suck up toner, plaster, cement, stone dust or drill dust. The
sucking up of these materials blocks the filter.
Regulating the suction power
You can set the suction power on the device individually as you
require it using the suction regulator. We recommend using
minimum suction power for delicate materials.
Select medium suction power for mattresses, upholstered furniture
and carpets. Select maximum suction power for tiled, wood and
other robust floors.
Secondary air valve
The secondary air valve is at the handle
•
Opening: pull upwards
•
Closing: push downwards
You can adjust the suction power by using the secondary air valve.
The wider the secondary air valve is opened, the less the suction power and vice-versa.
Open the secondary air valve to prevent curtains and the like from being sucked in.
Choose:
•
Minimal suction power for curtains and sensitive materials.
•
Medium suction power for upholstery cushions, mattresses, carpet floors.
•
Maximum suction power for tiled, wooden and robust floor surfaces with
heavy soiling.
