Dry vacuuming

ATTENTION

Vacuuming cold ashes

Device damage
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.

Wet vacuuming

ATTENTION

Wet vacuuming with a filter bag

Device damage
Do not use a filter bag when vacuuming wet.

ATTENTION

Operation with full container

When the container is full, a float switch closes the suc-
tion opening and the device runs at a higher speed.
Switch off the device immediately and empty the con-
tainer.

Note

If the device falls over, the float can also close. To make 
the device capable of vacuuming again, set up the de-
vice, switch it off, wait 5 seconds and then switch it on 
again.
