Maintenance indicator with reset but-
ton (dia. 39)
Some models are fitted with a mainten-
ance indicator.
The indicator lights up after approx. 50
hours of operation, which is equivalent
to about a year of average use. The
level of soiling of the dust compartment
filter and the exhaust filter must be
checked at this point.
If the filters are replaced, the indicator
must be reset. To do this the vacuum
cleaner must be switched on.
 Press the reset button.
The maintenance indicator will go out
and reset to zero.

The indicator can only be reset by
pressing the reset button after the
light has come on. Pressing the but-
ton at any other time will have no ef-
fect.
When to change the battery in the ra-
dio-control handle
Approximately every 18 months.
One 3 V battery (CR 2032) is required.
The vacuum cleaner can still be used
when the battery has run out or if

 Press the restart button on the va-
cuum cleaner (dia. 40).
The vacuum cleaner can continue to be
used in this way, but only at maximum
power.
