Warning sign for machines with
dust class L:
While the appliance is suitable for
extracting substances that pose a
slight threat to health, it is not
appropriate for reducing wood dust
in inhaled air.
Dust from material such as paint
containing lead, some wood
species, minerals and metal may
be harmful. Contact with or
inhalation of the dust may cause
allergic reactions and/or
respiratory diseases to the

Certain kinds of dust are classified
as carcinogenic, such as oak and
beech dust, especially in

6. Initial Operation

Before plugging in the device, check that
the rated mains voltage and mains
frequency, as specified on the rating label,
match your power supply.
Australia: Always use a residual current
device (RCD) protected supply with a
rated residual current of 30 mA or less.
6.1 Assembly
Insert the guide roller axles (8) until they engage
Fig. A. Fit the wheels (9) and secure with
screws (place a shim under the screw head)
Fig. B.
Fit the pipe support (10) until it clicks into place, as
shown (for ASA 32 L only)
6.2 Fitting the pleated filter
Fig. D+E: Fit the pleated filter (11) on the
housing as far as the limit stop and secure by
twisting the bayonet fitting (12).
6.3 Inserting the paper filter bag
Paper filter bags (13) are not suitable for wet vacu-
uming.
We recommend using paper filter bags for:
- Applications, where small amounts of fine dust are
created (e.g. spot-grinding and grinding of paint
and lacquer coatings, extraction of drilling
applications with small diameters < 10 mm of
short duration, etc.).
- Use of machines, such as: routers, planers, small
grinding machines, etc.
When using a fleece/paper filter bag the filter
cleaning is non-functional.
Switch off the appliance, remove the mains plug
and open the snap locks (3). Remove the upper part
(1) from the container (4).
Push the paper filter bag together with its cardboard
tab into the filter bag holder located on the suction
piece (inside the container)
Adjust the paper filter bag (13) so that it is flush with
the container wall and is not damaged when you
replace the upper part.
Remove the paper filter bag if you want to vacuum
coarser materials or liquids.
