Bosch Professional GAS 15 L SFC Original Instructions Manual page 11

– Put the top part of the vacuum cleaner (6) on and close
the catches (7).
Vacuuming up liquids
– Switch on the dust extractor.
The dust extractor is equipped with a float. Extraction is
stopped when the maximum filling level is reached.
– Switch off the dust extractor.
– Empty the container (1).
To prevent mould growth after wet extraction:
– Remove the top part of the dust extractor (6), then re-
move the pleated filter (28) and leave everything to dry
thoroughly.
Semi-automatic filter cleaning (see figure F)
The filter cleaning function should be used regularly, and at
the very latest when the suction power is no longer suffi-
cient.
How often filter cleaning needs to be carried out will depend
on the type and quantity of dust that has been vacuumed.
With regular use, the maximum conveying capacity will be
maintained for longer.
During semi-automatic filter cleaning (SFC), the air flow is
reversed to clean deposited dust from the flaps of the filter.
A pleated filter with surface dirt is still fully functional. It is
not necessary to clean the flat-pleated filter manually by
shaking or blowing it out; this may even damage the filter.
Triggering the SFC Filter Cleaning
– Use the palm of your hand to close the nozzle or vacuum
hose opening.
– Press the SFC switch (11) three times.
Maintenance and Service
Maintenance and Cleaning
Pull the plug out of the socket before cleaning or per-
u
forming maintenance on the vacuum cleaner, making
tool adjustments, changing accessories or putting
away the vacuum cleaner. This safety measure prevents
the vacuum cleaner from being started accidentally.
To ensure safe and efficient operation, always keep
u
the dust extractor and the ventilation slots clean.
Wear a dust mask when servicing and cleaning the va-
u
cuum cleaner.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
For the user to carry out maintenance, the dust extractor
needs to be disassembled, cleaned and maintained as far as
this is possible without endangering maintenance personnel
or other persons. Before disassembly, the dust extractor
should be cleaned to prevent any potential hazards. The
room/enclosure in which the dust extractor is disassembled
should be well ventilated. Wear personal protective equip-
Bosch Power Tools
ment while carrying out maintenance. After completing
maintenance, the maintenance area should be cleaned.
An inspection regarding the dust extraction capability must
be carried out at least once a year by the manufacturer or
someone who has been trained, e.g. to check for filter dam-
age, that the dust extractor is tight and that the control unit
is functioning correctly.
Class L vacuum cleaners which were located in dirty environ-
ments should have their exteriors, as well as all their com-
ponents, cleaned or treated with sealant. When performing
maintenance and repair work, all dirty parts that cannot be
cleaned satisfactorily must be disposed of. Such parts must
be disposed of in impermeable bags in accordance with the
valid provisions for disposing of such waste.
– Clean the housing of the dust extractor occasionally with
a damp cloth.
Cleaning the container
– Wipe the container (1) from time to time using a non-ab-
rasive off-the-shelf cleaning product and leave it to dry.
Cleaning the Filters
Regularly emptying the dust container and cleaning the fil-
ters will ensure optimum suction power. If suction power is
not achieved after that, the vacuum cleaner is to be brought
to the after-sales service.
