Semi-automatic filter cleaning (see figure G)
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
(6)
three times.
Maintenance and Service
Maintenance and Cleaning
u
Pull the plug out of the socket before cleaning or per-
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.
u
To ensure safe and efficient operation, always keep
the dust extractor and the ventilation slots clean.
u
Wear a dust mask when servicing and cleaning the va-
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.
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.
