Dry vacuuming

Vacuuming cold ashes

Only vacuum cold ash with an ash pre-separator.
ATTENTION
Defective or wet flat pleated filter
Device damage
Before initial startup, check the flat pleated filter for
damage and replace it if necessary.
Only vacuum with a dry flat pleated filter.
Note
Replace the filter bag in good time, as a filter bag that is
too full could be damaged. The fill degree of the filter
bag depends on the amount of dirt vacuumed. The filter
bag should be replaced more frequently when vacuum-
ing fine dust, sand, etc.
