suspended particles to be sucked into the fi lter
cyclone. The container can now be completely
removed from the machine. Carefully remove the
full sack from the edge of the bin, and immediately
seal it tight. Fit a new plastic sack, and carefully
pass the opening back over the edge of the bin.
Make sure that no folds occur, and that the sack is
not damaged. Then carefully install the bin under
the extractor and attach the two hooks, turn off the
machine and secure the bin to the machine once
more, making sure that the retaining hooks are
positioned correctly (see diagram) and check for
leaks.
Filter replacement
The fi ne fi lter should be replaced at least once a year.
HEPA fi lters should be replaced after every 300 hours
of operation. Wear a dust mask when replacing the fi lter.
Only use an original fi lter.
Release and lift off the lid. To prevent the escape of
dust, place a plastic sack over the cyclone, and remove
the fi lter cartridge. Clean the fi lter plate. Then fi t the new
fi lter.
- CAUTION! Do not reuse the main fi lter once it has
been removed from the machine.

The HEPA fi lter is removed by opening the lid and loos-
ening the cartridge. By gently tilting the loosened motor
head away from the cyclone, lateral pressure is exerted
on the HEPA fi lter cartridge secured to the motor head.
If necessary, repeat this procedure until the HEPA fi lter
cartridge falls into the fi ne fi lter cartridge. The HEPA
fi lter can then be removed together with the fi ne fi lter, as
described (also see diagram), and disposed of virtually
dust-free. The new fi lter cartridge is placed in the fi ne
fi lter and is sealed by carefully attaching the lid.
Caution
The manufacturer or a trained person must carry out
an inspection at least annually, e.g. damage to the fi lter,
air-tightness of the dust-extraction machine and the
function of the control unit.
The vacuum producer has an extremely long service life
and requires no maintenance. After approximately 1,000
operating hours, the seals should be inspected. If wear
is detected, these parts must be replaced.
