Set the rotary switch (1) to a volumetric flow
setting of 70 m³/h.
The dust extractor is switched on and off by a
power tool which is connected to the plug socket
(4). Set switch (2) to A (automatic on/off switch).
Connect the switched off tool to the mains
socket (4).
If the air speed in a tube system 35 mm in diameter
falls below the average air speed of 20 m/s, an
acoustic signal sounds. This indicates that the
paper filter bag must be changed or the vibration
equipment activated.
If the hose is 27 mm in diameter, set the rotary
switch (1) to a volumetric flow setting of 40 m³/h.
If the hose is 19 mm in diameter, set the
rotary switch (1) to a volumetric flow setting
of 20 m³/h.
With a tube diameter of 19 mm and unfavourable
flow conditions in the suction tube, in certain
circumstances the control display (3) flashes and
an acoustic signal sounds, although the paper filter
bag still does not need to be emptied. In this case,
lay out the tube straight and clean it; shorten the
tube if necessary.
If it is necessary to set the volumetric flow on the
dust extractor to a lower value (40 m³/h or
20 m³/h) because of a dust generator, the suction
tube will not be able to carry sufficient quantities
of dust. After each operation, the suction tube
must be removed from the appliance in order to
free it of dust.
The extraction openings on power tools are not
standardised. A rubber nozzle (adapter) 6.30 324
(not included in scope of delivery) that can be
adapted (shortened) to the relevant power tool has
therefore been made available.
7.3 Vacuuming
The dust extractor can be used commercially for
demanding jobs in areas such as craft work,
installation, building and construction, industry,
garages, painting, plastering, carpentry, and wood
work. Complies with EN 60335-2-69.
Dry vacuuming
Vacuum using a dry filter, dry appliance and dry
accessories only. In a damp state, the dust can
stick and become encrusted.
When vacuuming soot, cement, plaster of Paris,
flour or similar dust, insert a paper filter bag.
Always use the paper filter bag together with a
filter cartridge.
Use the paper filter bag for dry vacuuming only.
Wet vacuuming
Never operate the machine without
inserting a filter cassette first (14).
14
The machine may be destroyed and water may
also escape.
Vacuum without a paper filter bag. The filter
cartridges are suitable for wet vacuuming.
Before doing any wet vacuuming remove the dry
vacuumed material. Doing this will avoid intense
soiling and encrustation.
The integrated sensor switches off the motor when
the container is full. Empty the appliance. If the
appliance is not switched off, the restart protection
device remains effective. The appliance is not
operable again until after it has been switched off
and switched back on again.
After switching off, some water may run back out
of the hose.
Before emptying, first of all take the suction hose
out of the liquid.
If you are going to subsequently dry vacuum,
insert a filter. If there is a frequent changeover
between dry and wet vacuuming, we recommend
the use of a second (replacement) filter. Allow the
filter, container and accessories to dry so that no
dust is able to adhere to otherwise damp
components.
7.4 Dedusting the filter
The appliance is equipped with an
electromagnetic vibrator. Using this, dust which
sticks to the filter cassette (14) can be shaken off.
This ensures optimized use of the filter cartridges
and lengthens the work cycles.
8 Cleaning
Cleaning instructions
The exterior of class M appliances should be
cleaned by removing the dust and then wiped
clean, or else treated with sealants. Only then,
should they be taken from the danger zone. It must
be assumed that all appliance parts have become
dirty when they are taken from the danger zone.
Suitable action must therefore be taken to prevent
dust from spreading. When carrying out
maintenance and repair jobs, all objects which
have become dirty and cannot be cleaned
satisfactorily must be disposed of. They must be
disposed of in impermeable bags in accordance
with the regulations in force for the removal of such
waste products.
Clean the water sensor regularly and check it for
signs of damage.
Changing the paper filter bag
If the control display (3) blinks during IDE
operation, or the acoustic signal sounds during DR
operation, this means that the paper filter bag
must be emptied.
