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 vacuum cleaner should fail despite the care
taken in manufacturing and testing procedures,
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.
WARNING! This appliance must be earthed.
Important instructions for connecting a new

The wires in the cable are coloured according to
the following code:
Do not connect the blue or brown wire to the
earth terminal of the plug.
Important: If for any reason the moulded plug is
removed from the cable of this power tool, it
must be disposed of safely.

Container
Wipe out the container 9 from time to time with
a commercially available, non-scouring cleaning
agent and allow to dry.
Motor Protection Filter (see figure B)
The motor protection filter 13 is basically mainte-
nance- free. Take out the motor protection filter
from time to time and flush it with clear water. Al-
low the motor protection filter to dry thoroughly
before reinserting.
Level Sensors
14
Clean the level sensors 14 occasionally.
Unlock the latches 10 and remove the vacuum lid
3.
Clean the level sensors 14 with a soft cloth.
Reattach the vacuum lid 3 again and lock the
latches 10.
Malfunctions
In the case of insufficient vacuuming perform-
ance, check the following:
– Is the vacuum lid 3 attached properly?
– Is the hose system clogged?
– Are the extension tubes connected firmly?
– Is the container 9 full?
– Is the dust bag 11 full?
– Is the folded filter 12 clogged with dust?
Emptying at regular intervals ensures optimum
vacuuming performance.
If the vacuuming performance is not achieved
thereafter, take the vacuum cleaner to customer
service.
