9. Operation
It is essential that the safety precautions printed in these
operating instructions are read and observed.
9.1 Connecting to the mains supply
The voltage provided by the mains supply must corre-
spond to the voltage rating printed on the type plate.
The appliance must be switched off (switch position 0).
Insert the mains plug in the socket.
9.2 Switching on the appliance
Turn the switch to the "MAN" position. The appliance then
starts immediately (soft start function).
9.3 After finishing work
1. Turn the switch to the "0" position.
2. Disconnect the mains plug from the socket.
3. Roll up the hose and the supply cord.
10. Care and maintenance
10.1 Cleaning the filter
The filter is cleaned automatically during operation.
Nevertheless, should it become heavily soiled, complete
cleaning is necessary.
1. Switch the appliance off.
2. Hold the hose in the hand.
3. Use one hand to close off the end of the hose.
4. Turn the switch to the "MAN" position and, using the
hand to close off the end of the hose, allow the appli-
ance to run for 10 seconds.
In addition to this, the filter may be cleaned with water
and a cloth (do not use a high-pressure cleaning sys-
tem). Mineral dust may clog the filter, reducing its suc-
tion performance, if it is not cleaned adequately. Don't
knock the filter against a hard object or use a hard or
pointed object to clean it. This reduces the life of the filter.

10.5 Caring for the appliance
The outer casing of the appliance is manufactured from
impact-resistant plastic.
Always keep the ventilation slots free from obstructions.

the outer surface of the appliance at regular intervals with
a slightly damp cloth. Do not use a spray cleaning sys-
tem, steam cleaning system or running water for clean-
ing. This may negatively affect the electrical safety of the
