Dust bag change
indicator
When the dust bag or filters are full or if the accessories
are blocked (hose, pipe, nozzle), the dust bag change
indicator which is the max level of the digital indicator will
turn red. To ensure correct analysis, the maximum
suction level needs to be set and the floor nozzle lifted
from the floor.
In this case, change the dust bag or blocked filter or
remedy the blockage.
Use this control (slide valve) to reduce the suction level for
brief periods of time. During normal vacuum cleaning, this
slide valve should remain closed.
