Changing the filter
Your cylinder vacuum cleaner has the following filters:
A protective motor filter (Fig. 22/1)
prevents larger
particles from destroying the motor if the dust filter bag is
defective.
Replace: after each 4th change of dust filter bag, at the lat-
est every 6 months
A hygienic exhaust filter (Fig. 22/2)
filters the finest
particles from the blown-out air.
Replace: every 6 months
On the other hand, replace a damaged filter as soon as
possible.

Changing the protec-
tive motor filter
1.
Switch off the appliance and remove the dust filter bag
as described under
Z
Chapter 4.1, "Changing the dust
filter bag"
, steps 1-4.
2.
Remove the filter holder together with the protective
motor filter (Fig. 23).
3.
Separate the protective motor filter (Fig. 24/1) from the
filter holder (Fig. 24/2) over a dustbin.
4.
Clean the filter holder.
5.
If necessary lay the used protective motor filter on the
new cut-to-size protective motor filter. Draw the outline
of the filter and cut the protective motor filter to fit.
6.
If necessary, insert a new protective motor filter into the
filter holder.
7.
Together with the protective motor filter, push the filter
holder forcefully from above and correctly positioned
(curve up) into its receptacle.
8.
Insert a dust filter bag and close the dust chamber cov-
er. The cover clicks audibly into place.
ATTENTION:
The filters are not washable. The exhaust filter cannot be
re-used.
NOTE:
If it is only slightly dirty, it can also suffice to knock the
protective motor filter over a dustbin. However, we rec-
ommend that you use a new protective motor filter if you
have used 4 dust filter bags (order number
Z
Chapter
5.2, "Accessories and Spare Parts"
).
