The filter cleaning system must be actuated at the latest when
the vacuuming performance is no longer sufficient.
Regular use of the filter cleaning feature increases the tool life
of the filter.
To achieve ideal filter tool life, deactivate the automatic filter
cleaning in exceptional cases, e. g., when vacuuming pure liq-
uids or when working with a paper filter bag.
A flat-fold filter contaminated only on the surface is fully func-
tional. Manual cleaning of the flat-fold filter by striking/tap-
ping against it or blowing it out is not necessary, and can even
damage the filter.
Note: The automatic filter cleaning is factory-set.
Switching the automatic filter cleaning on/off is only possible,
when the VAC is running.

Maintenance and Service

Maintenance and Cleaning

 Before any work on the vacuum cleaner itself, pull the
mains plug.
 For safe and proper working, always keep the vacuum
cleaner and ventilation slots clean.
 Wear a dust protection mask when maintaining and
cleaning the vacuum cleaner.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
A dust-technical inspection is to be carried out at least once
every year by the manufacturer or an instructed person, e. g.
for damage of the filter, tightness against leakage of the vacu-
um cleaner and function of the control/monitoring unit.
For category L vacuum cleaners that were in contaminated
environments, the exterior as well as all machine parts should
be cleaned or treated with sealants. When performing mainte-
nance and repair work, all contaminated components that
cannot be cleaned to satisfactory must be disposed of. Such
components must be disposed of in impermeable plastic bags
conforming with the valid regulations for the disposal of such
waste.
For maintenance on behalf of the user, the vacuum cleaner
must be disassembled, cleaned and maintained as far as fea-
sible, without causing a risk for the maintenance personnel or
other persons. Prior to disassembly, the vacuum cleaner
should be cleaned in order to prevent any risks. The room/en-
closure in which the vacuum cleaner is disassembled should
be well ventilated. Wear personal protective equipment dur-
ing maintenance. After the maintenance, the maintenance ar-
ea should be cleaned.
