3.3 Suction force regulator (1.4)
The suction force regulator can be used to vary the
suction capacity. This permits a precise adaptation
to different substances to be picked up.
3.4 Connecting an electric tool
Warning! Observe the maximum connected load
on the appliance plug socket (see “Technical
Data“)!
Connect the electric tool to the appliance plug
socket (1.7).
Make sure that the electric tool is switched off when
plugging it in and unplugging it.
4 Application
A systainer can be fixed on the shelf (1.2) with the
two clamps (1.1).
A hose coupling (1.9, Order No. 487 072) can also
be plugged into the opening (1.8).
Alternatively, a hose clip (order No. 452 998) can
be fitted for coiling the suction hose.
The extensible push-handle (4.1) allows the vacuum
cleaner to be moved easily.
The lever (4.2) can be used to lock it in 2 positions.
Buffers (4.3, order No. 452 929) can be fitted on
the lower part of the vacuum cleaner.
They prevent the vacuum cleaner shifting when
being moved and operated.
4.1 Vacuuming dry materials
Before using the vacuum cleaner to evacuate dry
substances, a filter bag must always be inserted in
the container. Then the evacuated material can be
disposed of easily.
The filter element becomes damp after evacuating
liquids. A damp filter element suffers more wear and
tear if it is used for dry materials.
Accordingly, the filter element should be dried or
replaced with a dry one before dry operation.
4.2 Vacuuming liquids
The filter bag has to be removed before evacuating
liquids. We recommend use of a special wet filter
(Order No. 452 924).
When the maximum filling level is reached, a bag-
full indicator (2.8) automatically interrupts
extraction.
Warning: Do not evacuate combustible liquids!
If foam or liquid escapes, stop work immediately
and empty the dirt container (see 5.4).
4.3 The antistatic system (AS)
Friction in the suction hose causes electrostatic
charges which can result in unpleasant electric
shocks for the operator.
In order to conduct these static charges to earth,
the extraction units are provided with an antistatic
system as a standard feature.
However, antistatic hoses and accessories have
to be used in this case.
Caution: the antistatic function will only work if the
plug is plugged into a totally earthed socket.
5 Operation
5.1 Opening / closing the vacuum cleaner
- Open retaining clamps (2.2) ,
- Raise upper part (2.4) until support catch (2.5)
engages.
Follow the reverse order to close the appliance.
You must raise the upper part slightly before
depressing or disengaging the support.
5.2 Changing the filter
Warning: During the following procedure, take
care not to raise dust more than is unavoid-
able.
a) Changing filter bag (3.4, Order No.:
452 974)
- Open the vacuum cleaner,
- Remove the used filter bag (see printed text on
filter bag),
- Dispose of the used filter bag in accordance with
statutory requirements,
- Thoroughly clean the dirt container (2.7) and the
space (3.1) for suction turbine (wipe down with a
damp cloth),
- Insert new filter bag (see printed text on filter bag).
Important: Press the filter bag sleeve (3.3) firmly
onto the dust extraction fitting (3.2)!
- Close the vacuum cleaner.
b) Changing the filter element (2.3, Order No.
452 923)
Do not operate the suction unit without a filter
element. Otherwise, the motor may be damaged.
- Open the vacuum cleaner,
- Remove the used filter element (see printed text
on the filter element packaging),
- Dispose of the used filter element in a sealed,
dust-tight bag in accordance with statutory
requirements,
- Thoroughly clean dirt container (2.7) and space
(3.1) for the suction turbine (wipe down with a
damp cloth),
- Fit a new filter element (see printed text on the
filter element packaging),
- Close vacuum cleaner.
