Display
1. LED indicator Mains connector plugged in:
When the unit is plugged in, the LED lights up continuously.
2. LED indicator collection container full:
The unit is equipped with a sensor that detects whether the container/bag
is full. If this LED lights up continuously while the unit is running with the
inlet open, i.e. without load, containers/bags must be emptied.
3. LED indicator suction power intensity: Indicates the level of suction power
4. On/off/automatic switch-on knob: Switch on (I), switch off (0), automatic
switch-on (socket symbol): The unit starts when an electrical tool is
connected to the vacuum cleaner (6) and this is switched on.
5. Socket with cover for mains connection of electrical tool
Attention: Only connect electrical tools with max. 2200 W to the mains
connection of the vacuum cleaner.
6. Rotary knob for regulating the suction power
Left = little suction power, Right = full suction power
Filter cleaning
Filter cleaning should be carried out regularly. Filter cleaning becomes necessary
as soon as the suction power decreases (see chapter "Small repairs - do it
yourself!" in this operating manual). The unit is equipped with a semi-automatic
filter cleaning system. You can clean the filters by closing the inlet of the hand
tube (B).
Procedure:
Switch the appliance on and then to max. power (A). Close the inlet with your
hand or the receptacle/opening in the unit (B). After closing the inlet, wait 2-3
seconds until the maximum negative pressure has been built up. Press the
filter cleaning button (C) 5 times quickly in succession. This cleans the filter
and restores suction power.

2. Before operating the appliance, make
sure that a clean filter is fitted. A filter
is already installed in the industrial
vacuum cleaner when it is removed
from the original packaging.
1. Open the filter cover
To open the filter cover, pull the cover
upwards by the filter cover handle (D).
Open the lid until you hear a click and
the rod (C) has hooked into the catch
(B). Only when the catch (C) is properly
engaged can the hand be removed

handle (D).
3. When vacuuming different types of
dirt, the filter will eventually become
clogged and the suction power will
decrease. Therefore, clean the filter
regularly under running water and
let it dry.
ATTENTION
Read the chapter "Safety instructions" in these operating manual
carefully before setting up this industrial vacuum cleaner!
DANGER
Always disconnect the appliance from the mains before opening
the industrial vacuum cleaner!

described below.
1. Insert clean pleated filter
To close the filter cover, lift the cover by the filter cover handle (D) or by the handle
(A) with one hand. Carefully lift the rod (C) over the retaining hook (B) with another
and slowly lower the lid. When the rod (C) is above the retaining hook (B), take
your hand off the rod (C) and close the filter lid.
ATTENTION When opening and closing the filter cover, there is a risk of
crushing due to carelessness! Body parts can be crushed by
the filter cover folding down quickly. Therefore, be particularly
attentive, e.g. when resetting the retaining hook and when
slowly lowering the filter cover. Do not allow yourself to be
distracted by anything.
Make sure that the filter cover handle (D) is re-engaged in the collection container
so that the filter cover is securely locked. Check by lifting the machine by the
handle (A) to check that the lid is securely closed.
WARNING
Filter cleaning and filter charging may only be carried out by an
authorised specialist wearing suitable personal protective equip-
ment. This protects the person from substances hazardous to

the hooks slightly tilted upwards (1)
and then press the dust bag into a
horizontal position (2).
Use dust bag
2.1 Prepare the device for dry vacuuming
To collect dust and facilitate disposal, the vacuum cleaner can be used with a
dust bag or a disposal bag. The disposal bag is recommended for very fine dusts.
To insert the dust bag, remove the
head. To do this, pull the clamps
outwards with a little force and
lift the head off by the handle.
2. When the bag is full, close it with
the cable tie included with the bag.
2. When the dust bag is full, remove it in
the same way and close the dust bag
inlet with the lid.
Remove the head of the suction cup
Reattach the head of the suction cup
ATTENTION
Emptying, cleaning and filter changing may only be carried out
by an authorised specialist wearing suitable personal protective
equipment. This protects the person from substances hazardous
to health. Wear a dust mask (suitable for fine dust) when empty-
ing the container of fine dust of any kind or substances hazardous
to health.

6. Choose the right nozzle
Using the floor nozzle:
To vacuum up dry dust and dirt, use the floor
nozzle with bristle edge (1) for dry floors.
To vacuum up wet dirt, remove the bristle
rim with a screwdriver and insert the
rubber extractor (2) instead.
Attach the nozzle for the desired cleaning
purpose to the suction tube (3).

switch-on knob is set to "OFF".
Unplug the mains cable of the vacuum
cleaner before connecting power tools

4.2 Emptying the liquid container
To empty the liquid container, unscrew
the drain plug and remove it. Now the
liquid can flow out of the container.
Dry the container with a clean cleaning
cloth so that it is ready for the next use.
WARNING
Empty the collection container of the vacuum cleaner after each
use. This will also prevent spontaneous ignition of the contents of
the con tainer. After using the vacuum cleaner, the contents of the
dust collection container may contain components that can pose
a risk to health or the environment if disposed of incorrectly. The
safe and proper disposal of these substances, as well as the disposal
of the dust collection container if necessary, may only be carried
out by professionals wearing suitable personal protective equip-
ment. They must not be disposed of with household waste.
WARNING
The unit must be decontaminated before these operations. Rooms
in which these activities take place must have local filtered forced
ventilation and the area must be properly cleaned afterwards.
ATTENTION
Emptying, cleaning and filter changing may only be carried out
by an authorised specialist wearing suitable personal protective
equipment. This protects the person from substances hazardous
to health. Wear a dust mask (suitable for fine dust) when empty-
ing the container of fine dust of any kind or substances hazardous
to health.
4.1 Emptying the dust/dirt collection bin
To empty dust/dirt from the container,
remove the head of the appliance (see
chapter "Safety instructions"). If you use
a dust bag or waste bag, remove the bag
and insert a new one.
If you have been working with the electrical
tools, switch them off first and only then
disconnect the mains plug from the vacuum
cleaner. This prevents the electrical tool from
starting up uncontrollably.
Turn the rotary knob of the vacuum cleaner
to "0".
