When extracting large quantities of oak
or beech wood dust or dust that exceeds
the permitted limit values, only extract from a
single machine (electric or air tool).
Observe the following when extracting dust
generated by operating electric power tools:
If the exhaust air is discharged back into the
room, the air renewal rate L within the room
must be sufficient. The volume of air dis­
charged back into the room must not exceed
50% of the fresh air volume flow (room volume

Remember: A moist main filter clogs more
quickly when extracting dry materials. There­

WARNING
Hazardous dust
Damage to the respiratory passage
► Hazardous dust must never be taken in
during wet extraction.
Before the absorption of liquids remove the fil­
ter bag or safety filter bag (see Chapter
7.8 ). The use of a special wet filter is recom­
mended.
The dust extractor stops automatically when
the maximum level is reached.
CAUTION
Escaping foam and fluids
► Switch off the machine immediately and
empty the dirt trap.
8.4 The antistatic system
Friction inside the extraction hose causes static
electricity to develop during extraction. Operat­
ing personnel may receive unpleasant electric
shocks while working. The mobile dust extrac­
tor is fitted with an antistatic system as stand­
ard to discharge any static electricity that may
develop. However, always use the enclosed an­
tistatic extraction hose.
8.5 After finishing work
Pull the plug from the socket when the
machine is not in use and prior to main­
