If the vacuum cleaner is not switched off, the re-start protection
remains effective. The vacuum cleaner is ready for operation only
after the unit has been switched off and switched on again.
▶ Remove the suction hose from the liquid before emptying.
▶ After switching off, a small quantity of water can flow back out of
the hose, as a result of the high suction level and the favourable
flow condition in the container.
▶ After wet vacuum cleaning insert dry filters for picking up dry
dust.
When changing frequently between dry and wet vacuum
cleaning, use a second set of filters, preferably polyester folded
filter cartridges.
5.3 Sucking up asbestos-containing substances
Only vacuum cleaners of dust class H-asbestos may be used for
vacuuming asbestos-containing substances.
▶ Only work with a dry filter, vacuum cleaner and accessories to
prevent dust from sticking and becoming incrusted.
▶ For sucking up asbestos-containing substances: Insert the PE
emptying bag or fleece filter bag into the dirt container.
▶ Always use filter bags in conjunction with folded filter cartridges.
H-asbestos class vacuum cleaners should be preferably used as
vacuum cleaners for dry dusts.
l WARNING !
Health hazard !
Asbestos fibres in the air.
▶ Supply the work area with sufficient outside air (fresh air).
▶ Guide or clean extracted air in such a way that asbestos
fibres do not get into the breathing air of other persons.
▶ When filtering the extracted air, transport any dust in dust-
tight containers.
▶ Do not decant dust.
If there is a possibility of asbestos fibres becoming free:
▶ Absorb asbestos fibres at the outlet or point of origin.
▶ Then dispose of asbestos fibres in accordance with the state of
the art without any danger to persons or the environment.
If complete absorption of asbestos fibres is not possible:
▶ Take additional ventilation measures in accordance with the
state of the art.
After completion of the work:
▶ Carefully clean tools, including suction tubes and work
equipment.
▶ Carefully clean the working area.
▶ Moisten and properly remove objects contaminated with asbes-
tos fibres that cannot be cleaned.
