Maintenance and Cleaning

Before any work on the vacuum cleaner it-
self, pull the mains plug.
For safe and proper working, always keep
the vacuum cleaner and ventilation slots
clean.
If the replacement of the supply cord is neces-
sary, this has to be done by Bosch or an author-
ized Bosch service agent in order to avoid a safe-
ty 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 fil-
ter, tightness against leakage of the vacuum
cleaner and function of the control/monitoring
unit.
For category M vacuum cleaners that were in
contaminated environments, the exterior as well
as all machine parts should be cleaned or treat-
ed with sealants. When performing maintenance
and repair work, all contaminated components
that cannot be cleaned to satisfactory must be
disposed of. Such components must be dis-
posed of in impermeable plastic bags conform-
ing with the valid regulations for the disposal of
such waste.
For maintenance on behalf of the user, the vac-
uum cleaner must be disassembled, cleaned
and maintained as far as feasible, without caus-
ing a risk for the maintenance personnel or oth-
er persons. Prior to disassembly, the vacuum
cleaner should be cleaned in order to prevent
any risks. The room/enclosure in which the vac-
uum cleaner is disassembled should be well
ventilated. Wear personal protective equipment
during maintenance. After the maintenance, the
maintenance area should be cleaned.
If the vacuum cleaner should fail despite the
care taken in manufacturing and testing proce-
dures, repair should be carried out by an after-
sales service centre for Bosch power tools.
In all correspondence and spare parts order,
please always include the 10-digit article
number given on the type plate of the machine.
