4.1 Cleaning the filters

The battery powered hand-held vacuum
cleaner has the following filter inserts:
- Pre-filter (Fig. 6/1)
Prevents larger particles from blocking
the permanent filter.
- Permanent filter (Fig. 6/2)
Filters out fine particles from the
sucked-in air.
The filter inserts can become blocked after

some time and can thereby reduce the suction
power. It is therefore important that the filter
inserts are cleaned regularly.
If you determine that a filter insert is dam-

aged then replace it immediately.
NOTE:
We recommend that you replace the filter
inserts regularly.
1. Switch the appliance off and observe the
instructions under Chapter 3.2, "Putting
away".
2. Empty the dust container and remove the
filter inserts, Chapter 3.4, "Emptying the
dust container", Point 1-2.
3. Knock the filter inserts over a dustbin for a
rough clean.
4. Brush off the fabric and plastic parts with a
small brush.
NOTE:
If the filter inserts are extremely dirty, rinse
them with lukewarm water.
Then leave the filter inserts to dry (approx.
15 hours at room temperature). Only use
them again when they are completely dry.
5. Place the filter inserts inside again.

4.2 Cleaning the housing

WARNING:
Switch off the appliance before cleaning it.
Only clean the housing with a slightly

damp cloth. Do not use any cleaning agent,
scouring agent or alcohol as these can dam-
age the housing.
