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.
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.
Removing/Replacing the Folded Filter
(see figure C)
Replace a damaged folded filter 12 immediately.
– With a coin or similar, rotate the lock 6 by
1/4 turn in the direction of the arrow and
push the lock in.
– Fold up the vacuum lid 3, grasp the folded fil-
ter 12 by the fins, pull up and remove.
– Clean the folded filter 12.
– Insert new or cleaned folded filter 12 and en-
sure firm seating.
– Fold the vacuum lid 3 down again. With slight
pressure from above on the cover, the lock 6
will snap back again.
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 main-
tenance- free. Take out the motor protection fil-
ter from time to time and flush it with clear wa-
ter. Allow 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.
