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 vacuum cleaner
needs to be disassembled, cleaned and maintained as far as
this is possible without endangering maintenance personnel
or other persons. Before disassembly, the vacuum cleaner
should be cleaned to prevent any potential hazards. The
room in which the vacuum cleaner is disassembled should
be well ventilated. Wear personal protective equipment
while carrying out maintenance. After completing mainten-
ance, 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 vacuum cleaner 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.
