Maintenance indicator with reset but-
ton
Some models are fitted with a mainte-
nance indicator.
The indicator lights up after approxi-
mately 50 hours of operation, which is
equivalent to about a year of average
use. The level of soiling of the motor
protection filter and the exhaust filter
must be checked at this point.
The indicator must be reset each time
the filters are replaced. The vacuum
cleaner must be switched on to do this.
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 thread catchers?
(only possible for models with a re-
versible floorhead included as standard)
The thread catchers on the suction inlet
of the reversible floorhead can be re-
placed. Check them from time to time
and replace them if the pile has worn
down.
